In particular, the present invention relates to an electronic device that provides operation guidance by voice.
[0002]
[Prior art]
In recent years, electronic devices that are easy to use for not only healthy persons but also physically disabled persons have been developed. For example, there is an electronic device that not only displays on a monitor the state of the electronic device and contents that can be instructed to the electronic device, but also notifies the user with sound or voice guidance so that the visually impaired person can operate the electronic device. With the sound and the voice guidance, even a visually impaired person can determine what kind of situation the electronic device is currently in, what kind of command can be input, and what he / she should do.

[Problems to be solved by the invention]
However, in an electronic device such as a television or a radio that emits sound such as program sound, the sound guidance may be erased by the sound. In addition, when displaying the state of the electronic device and the contents that can be instructed to the electronic device on the monitor, a healthy person can instantly grasp the state of the electronic device and the contents that can be instructed by looking at the monitor. However, when the visually impaired person tries to know the state of the electronic device or the contents that can be instructed to the electronic device through the voice guidance, the voice guidance must be heard until the end. Therefore, it takes time to grasp the state of the electronic device and the contents that can be instructed through the voice guidance. Also, if the visually impaired person forgets the voice guidance once heard, the voice guidance must be heard again.
[0005]
In order to improve usability of electronic devices from the viewpoint of universal design, the present invention conveys voice guidance to the visually impaired person more reliably, and also describes the status of electronic devices and the contents that can be commanded in a short time through voice guidance. It is an object of the present invention to provide an electronic device that a visually handicapped person can grasp.
[0006]
[Means for Solving the Problems]
The electronic device of the present invention has an event processing means capable of accepting a request for operation explanation of the electronic device from a user in a plurality of input forms, and the event processing means accepting the operation explanation request in a predetermined input form. In this case, there is provided control means for setting operation guidance provided in accordance with the content of the operation explanation request, and notification means for notifying the operation guidance set by the control means by at least one of sound and voice. . By notifying the operation guide by sound or voice, even a visually impaired person can grasp the operation of the electronic device.
[0007]
Further, the control means sets the volume of the operation guide higher than the program sound reproduced by the electronic device so that the user can reliably hear the operation guide notified by sound or voice. In addition, since the volume of the operation guide is too loud if it is too loud, the control means may lower the volume of the program audio and set the volume of the operation explanation request higher than the volume of the program audio.
[0008]
Further, the control means may control the notification speed of the guide item according to the timing at which the guide item notified by the operation guide is selected. For example, if the user selects another guide item while the notifying unit is notifying the predetermined guide item, the control unit starts notifying the other guide item and notifying the predetermined guide item. This is performed at a speed according to the difference between the time when the user selects another guidance item and the time when the user selects another guidance item. Therefore, if the control is performed in this way, if the user selects another guide item immediately after the notification of the predetermined guide item is started, the notification speed of the other guide item increases, and the notification time of the entire guide item increases. Can be shorter.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
(Embodiment 1)
(Description of device configuration)
The electronic apparatus of the present invention is an electronic product such as a digital TV, a copier, a facsimile, an air conditioner, a personal computer, a car navigation system, a mobile phone, and a mobile device such as a PDA (Personal Digital Assistants). Hereinafter, a case where the electronic device is the digital TV 100 will be described.
[0010]
The digital TV 100 shown in FIG. 1 can provide a user with a recording reservation function using an EPG (Electronic Program Guide). The digital TV 100 receives program data and EPG transmitted by broadcasting or the Internet by a receiving unit 107 provided in the digital TV 100. The receiving means 107 transfers the received program data to the recording / reproducing means 153 of the control means 105 and the received EPG to the EPG storage means 108. When the program data is transferred, the recording / playback unit 153 plays back an image on the monitor 103 based on the program data, and outputs program audio data of the program data to the notification unit 106. The notifying unit 106 reproduces the output program audio through the speaker 104. Further, when the transferred program data is program data of a program reserved for recording, the recording / reproducing means 153 records the program on the recording medium 110.
[0011]
The EPG is information about a program such as a broadcast channel 201, a broadcast date and time 202, and a program name 203 of the program as shown in FIG.
[0012]
The user basically operates the digital TV 100 with the remote controller 300 shown in FIG. When a key provided on the remote controller 300 such as the cursor key 301 or the enter key 302 is pressed, the type of the pressed key is transmitted to the event processing unit 102 provided in the digital TV 100 as an operation explanation request.
[0013]
In order for a visually impaired person to operate the remote controller, it is necessary to store the correspondence between the position of each key of the remote controller 300 and the operation content, and it is not always easy to operate the digital TV 100 with the remote controller 300. Therefore, the digital TV 100 is operated not only by the remote controller 300 but also by voice.
[0014]
The voice uttered by the user is received by the voice conversion means 101 provided in the digital TV 100, converted into an electric signal corresponding to the voice by the voice conversion means 101, and sent to the event processing means 102 as an operation explanation request. Will be transferred.
[0015]
(Explanation of specific operation)
Here, the operation will be described in detail below on the assumption that a visually impaired person makes a recording reservation for a soccer game when a television program is displayed on the screen.
[0016]
The “program navigation” issued by the visually impaired as an explanation of the operation request is converted into an electric signal by the voice conversion unit 101 and transferred to the event processing unit 102. When the visually impaired person presses the menu key 303 of the remote controller 300 instead of issuing “program navigation”, the fact that the menu key 303 has been pressed is transmitted from the remote controller 300 to the event processing means 102.
[0017]
The event processing unit 102 recognizes that the program navigation transmitted from the audio conversion unit 101 or the menu key 303 transmitted from the remote controller 300 has been pressed as a start instruction of the operation guide. Then, the event processing unit 102 transfers, to the hierarchy shift unit 151 of the control unit 105, whether the instruction from the user has been received via the voice conversion unit 101 or directly from the remote controller 300 together with the activation instruction ( (FIG. 5, S531).
[0018]
When the route of the start instruction and the instruction from the user is transferred, the hierarchy shift unit 151 starts the program navigation mode A of the highest hierarchy of the operation guide having the hierarchical structure shown in FIG. S501). When the program navigation mode A is activated, the hierarchy shifting means 151 causes the in-hierarchy processing means 152 to execute the processing in the program navigation mode A.
[0019]
First, when the program navigation mode A is activated, the in-hierarchical processing means 152 displays the program navigation screen shown in FIG. As shown in FIG. 6, the program navigation screen includes a program table item 501, a counter program item 502, a genre search item 503, a program reservation item 504, a reservation list item 505, an information item 506, a pointer 521, a cursor key 301, and the like. Is displayed, and the user can obtain what to do next only from the visual information.
[0020]
When the user is a healthy person, the user sees the program navigation screen, and as a next operation, moves the pointer 521 to a desired item using the cursor key 301 and presses the enter key 302 to select the item. It can be determined that it is specified.
[0021]
However, if the user is visually impaired, the user cannot see the program navigation screen, and thus does not know whether the program navigation is actually running or what operation to perform next.
[0022]
In consideration of the fact that the user often operates the digital TV 100 by voice when the user is visually impaired, the layer shift unit 151 determines whether the instruction from the user is transferred via the voice conversion unit 101. When the program navi mode A is activated, data corresponding to the notification sound indicating that the program navi mode A has been activated is output to the notification means 106 (FIG. 5, S502 → S503).
[0023]
The notification means 106 notifies the notification sound from the speaker 104 based on the output data. The notification sound is, for example, a synthetic sound such as “bean” or a chime sound such as “ping-pong”. The type of sound, for example, the frequency, the tone, the pattern, the volume, and the like may be changed between when the operation guidance is started or ended and when the hierarchy in the menu is moved. For example, when the operation guidance mode is activated or terminated, a long sound “Peen” is given, and when the operation is within a hierarchy, “ping-pong”, “pong-ping”, and the like are given.
[0024]
When going deeper into the hierarchy, use "ping-pong" from high pitches to low pitches, and conversely, use "pong-pong" from low pitches to high pitches when going shallow, to impress the user with directionality and quickly understand the state of the device. Help. For a user who is accustomed to the operation to some extent, the user can reach the target layer by the number of floors pressed and the sound without having to listen to the voice guidance of each layer, thereby reducing the operation time. In addition, even when using a shortcut by voice input (shortcut function will be described later), the notification sound is generated by the number of advanced layers, and the execution sound of the device can be intuitively grasped by the pattern sound indicating the direction. Users can be relieved.
[0025]
The device is equipped with an on / off switching function so that the user can select on / off of voices and sounds emitted from the device according to his / her preference and learning degree of operation.
[0026]
By hearing the notification sound, even if the user is visually impaired, it is possible to recognize that the program navigation mode A has been activated and to recognize that the digital TV 100 is operating as intended. it can.
[0027]
When the data corresponding to the notification sound is output to the notification means 106, the layer shifting means 151 instructs the in-hierarchy processing means 152 to notify the voice guidance in the program navigation mode A.
[0028]
Upon receiving the instruction, the in-hierarchical processing means 152 displays the program navigation screen on the monitor 103, and also outputs data corresponding to voice guidance for causing the visually impaired person to recognize what to do next. The information is output to the notification means 106. The voice guidance starts with, for example, “Program navigation mode has been activated. Please specify the item.” The name of each item displayed on the program navigation screen (program listing, back program, genre search, program reservation) , Reservation list, and information) in this order.
[0029]
However, when the electronic device outputs program sound such as digital TV 100 or radio as in the present embodiment, the above-described notification sound and voice guidance may be erased by the program sound. Therefore, when outputting the data corresponding to the notification sound or the voice guidance to the notification means 106, the layer shift means 151 and the in-layer processing means 152 output the sound volume of the program sound being reproduced to the recording / reproduction means 153. To obtain the playback volume of the program audio. The layer shifting means 151 and the in-layer processing means 152 change the data corresponding to the notification sound or the voice guidance so that the notification sound or the voice guidance is notified at a volume higher than the program sound being reproduced. Is output to the notification means 106. As a result, the notification means 106 notifies the notification sound and the voice guidance at a volume higher than the program sound, so that the possibility that the notification sound and the voice guidance are erased by the program sound is reduced.
[0030]
Also, if the volume of the notification sound and the voice guidance is too loud, it is noisy. When the program navigation mode A is activated, the layer shift unit 151 instructs the recording / reproducing unit 153 to reduce the volume of the program audio being reproduced. To do so. As a result, the recording / reproducing means 153 reduces the volume of the program audio data and outputs it to the notifying means 106. By reducing the volume of the program sound in this way, it is possible to reduce the possibility that the notification sound and the voice guidance are drowned out by the program sound without increasing the volume of the notification sound and the voice guidance.
[0031]
In addition, the user may be able to set the volume of the notification sound and the voice guidance independently of the volume of the program audio. For example, when the user presses the operation guide volume key 308 of the remote controller 300 while the program is being reproduced on the monitor 103 and the speaker 104 or when the operation explanation is activated, the event processing unit 102 shifts to the hierarchical level. The means 151 is notified that the operation guide volume key 308 has been pressed.
[0032]
When the operation guide volume key 308 is pressed, the layer shift unit 151 outputs data corresponding to the voice guidance “Please indicate the volume of the operation guide.” To the notification unit 106. The notification means 106 notifies the voice guidance from the speaker 104.
[0033]
When the user hears the voice guidance, the user says, for example, “increase” or “decrease” to the digital TV 100. The voice uttered by the user is converted into an electric signal by the voice conversion unit 101, and Via the event processing means 102, it is received as a sound volume instruction by the layer shifting means 151.
[0034]
Upon receiving, for example, a volume instruction of “increase”, the hierarchy shifting unit 151 notifies the in-hierarchy processing unit 152 of the volume instruction. As a result, the layer shifting unit 151 and the in-layer processing unit 152 can recognize that there is a volume instruction of “increase”. After receiving the sound volume instruction, the hierarchy shifting means 151 and the in-hierarchy processing means 152 change the data corresponding to the notification sound and the voice guidance so that the notified volume is higher than usual, and Output to the notifying means 106.
[0035]
When the in-hierarchy processing means 152 outputs the data corresponding to “Program navigation has started. Specify a guidance item.” To the notification means 106 as described above, then the top guidance on the program navigation screen is displayed. Data corresponding to the item name "program guide" is output to the notification means 106 (FIG. 5, S504 → S507).
[0036]
As a method of deciding an item, both a method of inputting with a button of the remote controller 300 and a method of inputting by voice are provided.
[0037]
There are at least the following three types of voice guidance output from the device when the user moves into a certain hierarchy and switches the screen. There are three types of guidance: a guidance indicating what screen to do, a guidance to guide the user on what to do on the screen, and a guidance for presenting options that the user can select.
[0038]
For example, when entering the program navigation mode A, there are three types of voice guidance: "Entered the program navigation", "Please select an item", and "Program guide" which is the guidance for presenting the next choice. Voice guidance appears. At this time, the user can use the cross key of the remote controller 300 to move the cursor to a target item on the screen and press the enter key to select the item. A user with normal vision can determine items by this method, but this method may be difficult for a visually impaired person. In that case, a method of voice guidance and determination of items by a remote controller is used. As a method of guidance by voice, first, all the item names are sequentially read out by the device by voice inputting “all” or the like to know the items on the screen, and thereafter, the target items are displayed on the remote controller 300. A method of selecting with the enter key 302 is possible. When the cursor is moved between items on the screen using the cross key 301, the user can determine the item name at which the cursor is located by reading the item name at which the cursor is located. By pressing the key 302, a predetermined item is selected. When all the items are read out, the next item is read out after a predetermined time (for example, one second) elapses after one item is read out from the device. Thus, the user can select an item by pressing the enter key 302 while the target item is being read out or before the next item is read out.
[0039]
As a method of determining an item, it is also possible to provide guidance by voice and perform an operation such as determination by voice.
[0040]
In this case, first, the operation guidance and selection items as options are read aloud by voice, and if it is recognized by voice recognition that a predetermined keyword such as “determine” or “return” has been uttered, the remote control The same operation as pressing the operation button 300 is performed. If a desired item name is input by voice, a shortcut function works regardless of whether the item exists in the hierarchy or not, and the item can be directly selected by skipping the middle hierarchy.
[0041]
The voice recognition function may be provided in the main body of the digital TV 100. However, by incorporating a microphone and a voice recognition circuit inside the remote controller 300, a signal equivalent to a button operation is generated. Is also good.
[0042]
Here, when the user utters “decision” toward the digital TV 100 before the next item “back program” is read out after the “program table” is notified, the item is the currently notified item. "Program guide" is determined. In this way, the item can be selected by saying "decision" when the item is presented (when it is read out), but instead of saying "decision", by saying the item name, You can also choose directly. The timing of uttering the item name does not need to be after the item name is presented from the device side, that is, may be uttered at any stage of the hierarchy. As a result, the operation in the middle of the hierarchy can be skipped by directly selecting the item without having to follow the hierarchy of the menu screen as in the related art.
[0043]
This function is called "shortcut" in this specification.
[0044]
Alternatively, the user can perform the determination operation by pressing the determination key 302 of the remote controller 300 instead of speaking.
[0045]
When the operation of “determination” is received by the above utterance or the button operation of the remote control, the event processing unit 102 transfers the “determination” to the in-layer processing unit 152.
[0046]
However, in the present embodiment, since the purpose of the user is to activate the genre search mode B in which the recorded program can be searched, while the “program guide” is notified from the speaker 104 or when the user is notified. Until a predetermined period elapses, the user does not say “enter” or press the enter key 302.
[0047]
When a predetermined time elapses after the output of the data corresponding to the “program table”, the in-hierarchical processing means 152 determines whether there is an item to be notified next (FIG. 5, S508). Here, since there is a “counter program” which is an item to be notified after the “program table”, the in-hierarchical processing means 152 outputs a predetermined time after finishing outputting the data corresponding to the “program table”. The data corresponding to the "back program" is output to the notification means 106 (FIG. 5, S504). Then, the notifying unit 106 notifies the “back program” from the speaker 104.
[0048]
At this time, the user does not say “enter” nor press the enter key 302. When a predetermined time elapses after the output of the data corresponding to the “back program” has been completed, the in-layer processing means 152 determines whether there is an item to be notified next (FIG. 5, S505 → S508). Here, since there is "genre search" which is an item to be notified next to "back program", the in-layer processing means 152 outputs data corresponding to "genre search" to the notification means 106 next (FIG. 5, S504). Then, the notifying unit 106 notifies the “back program” from the speaker 104.
[0049]
For example, the user says “determined” to the digital TV 100 while “genre search” is informed.
[0050]
The “decision” issued by the user is received by the event processing unit 102 via the voice conversion unit 101. Then, upon receiving the decision, the event processing means 102 transfers the decision to the in-layer processing means 152 (FIG. 5, S532).
[0051]
When “decision” is received while outputting data corresponding to “genre search”, the in-layer processing unit 152 recognizes that the genre search mode B has been designated by the user (FIG. 5, S505). The in-layer processing means 152 notifies the tier moving means 151 that the genre search mode B has been designated.
[0052]
Upon receiving the notification, the layer shift unit 151 activates the genre search mode B (FIG. 5, S511 → S512).
[0053]
If it is troublesome to notify the “program guide” or the “back program” until the “genre search” is notified as described above, the user is notified of the “program table” or the “back program”. Occasionally, the user may say “next” or press the down cursor key 301 of the remote controller 300. The fact that the user has pressed the “next” or down cursor key 301 is received by the event processing unit 102 as a selection instruction. Upon receiving the selection instruction, the event processing unit 102 generates a notification stop instruction, and transfers the notification stop instruction to the in-layer processing unit 152 (FIG. 5, S533).
[0054]
Upon receiving the notification stop instruction, the in-hierarchical processing unit 152 causes the notification unit 106 to stop the notification of the guide item that is currently being notified, and if there is a guide item to be notified next, responds to the guide item. The next guidance item is notified to the notifying unit 106 by outputting the data to be notified to the notifying unit 106 (FIG. 5, S506 → S508 → S504).
[0055]
That is, when the "program guide" is notified, the notification of the "program guide" is stopped and the "counter program" is notified, and when the "counter program" is notified, the notification of the "counter program" is performed. Is stopped and "genre search" is notified. Therefore, immediately after the program navigation mode A is activated, the user says “next” twice, so that “genre search” is notified immediately after the program navigation mode A is activated.
[0056]
It should be noted that the notification of the "program guide" from the speaker 104 is slightly delayed from when the user says "program navigation" to activate the program navigation mode A. , "Program guide" is not notified at all, and "back program" is the first guide item to be notified in the voice guidance. Of course, if the user says "next" twice after the user says "Program Navi" before being notified of both "Program Guide" and "Back Program", "Genre Search" will be the first in the above voice guidance. It is a guidance item to be notified.
[0057]
If the user does not say "OK" or press the enter key 302 until a predetermined time has elapsed since the last guidance item (information) output by the voice guidance, the in-hierarchical processing means 152 enters a waiting state (FIG. 5, S509).
[0058]
As described above, when the in-hierarchy processing unit 152 is in the waiting state, that is, when the guidance item is specified after the voice guidance is notified to the end, the user specifies the name of the guidance item to be specified (in the present embodiment, “ Genre search ”) to the digital TV 100. Here, the "genre search" issued by the user is converted into an electric signal by the voice conversion means 101 and transferred to the event processing means 102.
[0059]
When the event processing means 102 receives the "genre search" from the voice conversion means 101, the event processing means 102 transfers the "genre search" to the in-layer processing means 152 (FIG. 5, S534).
[0060]
Upon receiving the “genre search”, the in-layer processing means 152 notifies the above-mentioned layer shifting means 151 that the genre search mode B has been designated.
[0061]
Upon receiving the notification that the genre search mode B has been designated as described above, the hierarchy shift unit 151 activates the genre search mode B which is a lower hierarchy of the program navigation mode A as shown in FIG. 5, S511 → S512).
[0062]
When the genre search mode B is activated, the hierarchical transition unit 151 takes a lower order than the operation guidance activated immediately before, considering the case where the user is visually impaired, as in the case of the activation of the program navigation mode A. Data corresponding to the notification sound indicating that the hierarchical operation guidance has been started is output to the notification means 106 (FIG. 5, S503). The notification means 106 notifies the notification sound from the speaker 104.
[0063]
Note that the operation guidance of the lower hierarchy is activated while the operation guidance of the predetermined hierarchy is activated as in the case where the genre search mode B is activated, and the operation guidance is activated as in the case where the program navigation mode A is activated. It is desirable to make the volume, frequency, timbre, notification time, rhythm, melody sound, etc. of these notification sounds different so that the notification sound can distinguish the activation of the operation guide of the predetermined hierarchy from the absence state. For example, the notification sound indicating that the lower-level operation guidance has been activated during the activation of the predetermined-level operation guidance is set to “ping-pong”, and the notification that the predetermined-level operation guidance has been activated from the state where the operation guidance has not been activated. Make the sound "bean".
[0064]
Upon outputting the data corresponding to the notification sound, the layer shift unit 151 instructs the in-layer processing unit 152 to notify the voice guidance in the genre search mode B. When the voice guidance is instructed, the in-layer processing unit 152 displays the genre search screen shown in FIG.
[0065]
As shown in FIG. 7, the genre search screen includes nine guide items, namely, news / report items 601, sports items 602, culture / entertainment items 603, drama items 604, music items 605, variety items 606, and movie items 607. , An animation / special effects item 608, other items 609, a pointer 621, and an operation unit such as a cursor key 301, so that the user can obtain what to do next only from the visual information.
[0066]
Further, the in-layer processing means 152 outputs data corresponding to voice guidance for causing the visually impaired person to recognize what to do next to the notifying means 106 (FIG. 5, S504). The voice guidance starts with, for example, “Genre search mode B has been activated. Please specify an item.” The name of each item displayed on the genre search screen (news / report, sports, culture / entertainment, Drama, music, variety, movie, animation / sFX, etc.).
[0067]
In the same manner as when the genre search item is specified on the program navigation screen, since the soccer is included in the sport, for example, a predetermined time elapses while the “sports” of the voice guidance is announced and after the announcement. By then, say "decision" toward digital TV 100. Note that when designating “sports”, the user may say “sports” to the digital TV 100 after the voice guidance has been notified to the end and the in-hierarchy processing unit 152 is in a waiting state as described above. . In addition, as described above, the user may use the “next” and down cursor keys 301 to stop the notification of news / reporting on the way, and to promptly notify “sports”.
[0068]
Of course, the above-mentioned hierarchy shifting means 151 and the above-mentioned intra-layer processing means 152 activate the above-mentioned program navigation mode A so that the user can surely hear the notification sound and the voice guidance indicating that the genre search mode B has been activated. As in the case of the above, the data corresponding to the notification sound and the voice guidance is changed so that the volume of the notification sound and the voice guidance becomes larger than the volume of the program voice and output to the notification means 106.
[0069]
The “decision” issued by the user is received by the event processing unit 102 via the voice conversion unit 101. Upon receiving the decision from the voice conversion means 101, the event processing means 102 transfers the decision to the in-hierarchy processing means 152 (FIG. 5, S532).
[0070]
Upon receiving the decision, the in-layer processing means 152 recognizes that the sports sub-genre mode C has been specified by the user (FIG. 5, S505). When recognizing that the sports sub-genre mode C has been selected, the in-layer processing means 152 notifies the layer shifting means 151 that the sports sub-genre mode C has been designated.
[0071]
Upon receiving the notification, the layer shifting unit 151 activates a sports sub-genre mode C which is a lower layer of the genre search mode B shown in FIG. 4 (FIG. 5, S512 → S513). Also, when the sports sub-genre mode C is activated in consideration of the case where the user is a visually impaired person, the above-mentioned hierarchy shifting means 151 informs that the operation guidance of the lower hierarchy than the genre search mode B has been activated. The data corresponding to "ping-pong" is output to the notification means 106 (FIG. 5, S503). The notifying unit 106 notifies a notification sound from the speaker 104 based on the data.
[0072]
Upon outputting the data corresponding to the notification sound, the layer shift unit 151 instructs the in-layer processing unit 152 to notify the voice guidance of the sports sub-genre mode C.
[0073]
When the voice guidance is instructed, the in-layer processing means 152 displays the sports screen shown in FIG.
[0074]
As shown in FIG. 8, on the sports screen, all operation units such as an item 701, a baseball item 702, a soccer item 703, a golf item 704, a public competition item 705, other items 706, a pointer 721, and cursor keys 301 are displayed. Here, too, the user can obtain what to do next only from the visual information.
[0075]
Further, in consideration of the case where the user is a visually impaired person, the in-hierarchical processing means 152 outputs data corresponding to voice guidance for causing the visually impaired person to recognize what to do next. The data is output to 106 (FIG. 5, S504). The voice guidance starts with, for example, "Sports subgenre mode has been activated. Please specify the item." The name of each item displayed on the sports screen (all, baseball, soccer, golf, public sports) , Etc.) in order.
[0076]
Here, in order to reserve the recording of the soccer program, for example, the user says “decision” to the digital TV 100 while “soccer” is informed. The “decision” is converted into an electric signal by the voice conversion unit 101 and transferred to the event processing unit 102.
[0077]
Upon receiving the decision from the voice conversion means 101, the event processing means 102 transfers the decision to the in-hierarchy processing means 152 (FIG. 5, S532).
[0078]
The in-layer processing means 152 notifies the above-mentioned layer shifting means 151 that the soccer mode has been designated.
[0079]
Upon receiving the notification, the layer shifting unit 151 starts a soccer mode which is a lower layer of the sports sub-genre mode C shown in FIG. 4 (FIG. 5, S512 → S513). Further, when the soccer mode is activated in consideration of the case where the user is visually impaired, the layer shifting means 151 outputs the notification sound “ping-pong” indicating that the operation guidance of the lower layer than the sports sub-genre mode C has been activated. Is output to the notification means 106 (FIG. 5, S503). The notifying unit 106 notifies a notification sound from the speaker 104 based on the data.
[0080]
Upon outputting the data corresponding to the notification sound, the layer shift unit 151 instructs the in-layer processing unit 152 to notify the voice guidance in the soccer mode.
[0081]
When the voice guidance is instructed, the in-layer processing means 152 outputs to the notification means 106 data corresponding to the voice guidance of "Soccer mode has been activated. Soccer program is being searched."
[0082]
The in-hierarchy processing means 152 recognizes the instruction to notify the voice guidance in the soccer mode as a soccer program search command, and from the EPG stored in the EPG storage means 108, the program name 203 includes soccer. Search for programs to be played. Then, as shown in FIG. 9, a program in which a soccer is included in the program name 203 is extracted, and three items of the extracted broadcast date / time 202, program name 203, and broadcast channel 201 are displayed on the monitor 103 as guide items 211. indicate.
[0083]
Here, also in consideration of the case where the user is a visually impaired person, the in-hierarchical processing means 152 outputs data corresponding to the notification sound indicating that the search has been completed to the notification means 106, and the notification means 106 The notification sound is notified from the speaker 104. Further, the in-hierarchy processing means 152 outputs data corresponding to the program guide item 211 to the notifying means 106, for example, in order from the program with the earliest broadcast date and time 202, and the notifying means 106 transmits the guide item 211 from the speaker 104. Notify.
[0084]
When the visually impaired person is notified of the guide item 211 of the desired soccer program, he or she says “decision” to the digital TV 100 at that time. The "decision" is converted into an electric signal by the voice conversion means 101 and transferred to the event processing means 102.
[0085]
Upon receiving the decision, the event processing means 102 transfers the decision to the in-layer processing means 152 (FIG. 5, S532). When the decision is transferred, the intra-layer processing means 152 acquires the guide item 211 currently output to the notification means 106. Then, the in-layer processing means 152 recognizes the program corresponding to the acquired guide item 211 as the program to be reserved.
[0086]
In the present embodiment, since there is only one reservation target program that can be specified in the soccer mode, the in-layer processing unit 152 notifies the above-mentioned hierarchy transition unit 151 of the specified recording target program.
[0087]
The in-layer processing means 152 activates a reservation mode for setting details of the recording reservation of the program.
[0088]
When the notification is received as an instruction to activate the reservation mode, the layer shift unit 151 activates the reservation mode for setting details of the recording reservation of the program (FIG. 5, S511 → S512).
[0089]
However, if there are a large number of soccer programs, the user must listen to the guidance items 211 of many other programs until the guidance item 211 of the program to be reserved for recording is notified. It is very tiring to keep listening to the guide items 211 of many programs.
[0090]
Thus, the in-hierarchical processing means 152 forms a guide item group 212 from guide items 211 of programs having the same attribute among soccer programs. The attribute is, for example, the broadcast date of the program. If the attribute is the broadcast date of the program, the guide item group 212 includes guide items 211 of the program on the same broadcast date.
[0091]
When the guide item group 212 is configured, the in-hierarchy processing means 152 outputs to the notification means 106 in order from the data corresponding to the guide item group 212 to which the program with the earliest broadcast date belongs. The notification means 106 notifies the guide item 211 belonging to the guide item group 212 from the speaker item 104 from the guide item group 212 with the earliest broadcast date from the speaker 104, and broadcasts the message after a predetermined interval when the notification of the guide item group 212 is completed. The day notifies the guide item group 212 of the next day.
[0092]
Therefore, the notification means 106 first notifies the guide item 211 of the program broadcasted today. After the notification of the guide item 211 of the program to be broadcasted today is finished, the notification unit 106 notifies the guide item 211 of the program to be broadcast tomorrow after a predetermined interval. By providing a predetermined interval in this way, if there is an interval, the user recognizes that the broadcast date of the program for which the guide item 211 is to be notified is the next day of the program for which the guide item 211 has been notified. can do. Therefore, the user listens to the broadcast date broadcast after the broadcast interval, and only when the broadcast date is the broadcast date of the program for which recording reservation is desired, the guide item 211 that is broadcast following the broadcast date carefully. Just ask. In the case where the category of information is classified by auditory information, in addition to the time interval, a notice sound such as a "beep" sound is inserted, or the user notices a change by changing the pitch of the read-out voice. You may let it.
[0093]
Also, if there are many soccer programs, it may take time until the guide item 211 of the program desired by the user is notified. For example, when the guide item 211 is notified in order from the program with the earliest broadcast date and time, the guide item 211 of the program broadcast five days later is notified after the guide item 211 of the program broadcast four days from today is notified. Is done.
[0094]
Then, the user listens to the broadcast date and time 202 of the guide item 211 to be notified, and if the broadcast date is not five days later, says “next” or presses the down cursor key 301. The fact that the user has pressed the “next” or down cursor key 301 as described above is received as a selection instruction by the in-layer processing means 152 via the event processing means 102.
[0095]
Upon receiving the selection instruction, the in-hierarchical processing means 152 causes the notifying means 106 to stop the notification of the guide item 211 currently being notified, and if there is a guide item to be notified next, the in-hierarchical processing means 152 The corresponding data is output to the notifying unit 106, and the notifying unit 106 is notified of the next guidance item 211.
[0096]
Therefore, for example, by saying “next” after hearing the broadcast date, the user can avoid listening to the program name 203 and the broadcast channel 201 of the soccer program broadcasted for four days from today. Accordingly, the time until a desired soccer program is notified is shortened.
[0097]
Further, by adjusting the notification speed of the guide item 211 of the notification unit 106, the time until a desired soccer program is notified may be shortened.
[0098]
For example, when the user presses the right cursor key 301 while the notification unit 106 is notifying the guide item 211 of the predetermined program, the in-hierarchical processing unit 152 via the event processing unit 102 is pressed. Is received that the right cursor key 301 has been pressed.
[0099]
When the in-hierarchy processing means 152 receives the notification that the right cursor key 301 has been pressed, how many seconds have passed since the start of outputting the guidance item 211 currently output to the notification means 106 to the notification means 106? Is measured. After measuring the time, the in-layer processing means 152 instructs the notifying means 106 to notify the next and subsequent guidance items 211 within the time. In order to measure such time, the in-hierarchical processing means 152 stores the output start time of each guide item 211.
[0100]
In this case, as the user shortens the time from when the guidance item 211 is notified to when the right cursor key 301 is pressed, the notification speed of the guidance item 211 increases. Therefore, the time until a desired soccer program is announced is shortened.
[0101]
In addition, a normal notification speed of the notification unit 106 may be determined by a user. For example, when the user presses the notification speed setting key 307 of the remote controller 300 when the program is being reproduced on the monitor 103 and the speaker 104 or when the operation explanation is activated, the event processing unit 102 The notification that the notification speed setting key 307 has been pressed is transmitted. When receiving the notification that the notification speed setting key 307 has been pressed, the accepting unit 111 outputs data corresponding to the voice guidance “Please input the notification speed.” To the notification unit 106, and the notification unit 106 notifies the voice guidance.
[0102]
When the user hears the voice guidance, the user speaks to the digital TV 100, for example, a notification speed instruction such as “fast” or “slow”. The voice uttered by the user is converted into an electric signal by the voice conversion means 101 and received by the reception means 111 via the event processing means 102.
[0103]
For example, upon receiving a signal corresponding to “fast”, the accepting unit 111 notifies the notifying unit 106 of the signal. After receiving the notification, the notification means 106 issues a notification sound or voice guidance at a speed corresponding to “fast”.
[0104]
Note that, instead of pressing the notification speed setting key 307, if the user says “notification speed setting”, the “notification speed setting” is converted into an electric signal by the voice conversion means 101, and the notification speed setting instruction is issued. May be transferred to the receiving unit 111 as above.
[0105]
By the way, when the reservation mode is activated based on the activation instruction as described above, in consideration of the case where the user is a visually impaired person, the above-mentioned hierarchy shifting means 151 activates the operation guidance of the lower hierarchy than the soccer mode. The data corresponding to the notification sound "ping-pong" is output to the notification means 106 (FIG. 5, S503). The notifying unit 106 notifies a notification sound from the speaker 104 based on the data. From the notification sound, the visually impaired person recognizes that the “decision” has been received by the digital TV 100 and the reservation mode has been activated.
[0106]
Upon notifying the notification sound, the layer shift unit 151 instructs the in-layer processing unit 152 to notify the voice guidance in the reservation mode.
[0107]
When there is an instruction to notify the voice guidance, the in-layer processing means 152 displays the reservation screen shown in FIG. On the reservation screen, as shown in FIG. 10, an operation unit such as an item 910 for specifying a recording method, an item 920 for specifying a recording medium 110, an item 930 for specifying whether or not to make a reservation, a pointer 921, a cursor key 301, etc. Is displayed, and also on the reservation screen, the user can obtain what to do next only from the visual information.
[0108]
Further, the in-layer processing means 152 outputs data corresponding to the following voice guidance to the notifying means 106 so that the visually impaired person can recognize what to do next (FIG. 5, S504).
[0109]
First, the in-hierarchical processing means 152 provides a voice guidance of “Please select a reservation method. Make a viewing reservation or make a recording reservation” to ask the user whether to make a viewing reservation or a recording reservation. The information is output to the notification means 106. The viewing reservation means that the reserved program is displayed on the monitor 103 and the speaker 104 at the designated time without recording, and the recording reservation means that only the recording is performed without reproducing the program.
[0110]
The notification unit 106 notifies the voice guidance from the speaker 104.
[0111]
For example, while the user is informed of “Do you want to make a recording reservation?”, If the user says “decision” to the digital TV 100, “decision” is sent to the event processing unit 102 via the audio conversion unit 101. Received. Upon receiving the “decision”, the event processing means 102 transfers the decision to the in-layer processing means 152 (FIG. 5, S532).
[0112]
Upon receiving the decision, the intra-layer processing means 152 recognizes that the recording reservation has been designated (S505 in FIG. 5).
[0113]
Then, upon receiving the decision, the in-hierarchical processing means 152 confirms whether there is any other guide item that can be specified in the reservation mode. In the reservation mode, guidance items that can be specified include guidance items for specifying the recording medium 110 and specifying whether or not to register a reservation, in addition to the reservation method. For this reason, after the confirmation, the in-layer processing means 152 outputs data corresponding to the voice guidance “Please designate a recording medium. Hard disk, DVHS, DVD” to the notifying means 106 (FIG. 5, S504). . The notification means 106 notifies the voice guidance.
[0114]
For example, the user may say “OK” to the digital TV 100 while “DVD” is being notified. Then, “decision” is received by the event processing unit 102 via the voice conversion unit 101. Upon receiving the “decision”, the event processing means 102 transfers the decision to the in-layer processing means 152 (FIG. 5, S532).
[0115]
Upon receiving the decision, the in-layer processing means 152 recognizes that a DVD has been designated (FIG. 5, S505). Further, the in-hierarchy processing means 152 outputs data corresponding to the voice guidance of “specify whether or not to register a reservation. Do not reserve or make a reservation” to the notifying means 106, and the notifying means 106 Then, the voice guidance is notified (FIG. 5, S504).
[0116]
For example, while the user is informed of “reserve”, saying “decision” toward the digital TV 100, the “decision” is received by the event processing means 102 via the voice conversion means 101. Upon receiving the decision, the event processing means 102 transfers the decision to the in-layer processing means 152 (FIG. 5, S532). Upon receiving the decision, the in-layer processing means 152 recognizes that the reservation of the soccer program specified in the soccer mode has been registered (S505 in FIG. 5).
[0117]
When recognizing that the reservation has been registered, the in-hierarchical processing means 152 instructs the recording / reproducing means 153 to broadcast date and time of the soccer program selected in the soccer mode, the broadcast channel, the reservation method designated in the reservation mode, and the recording medium 110. Register
[0118]
Based on this registration, the recording / playback means 153 records the soccer program specified by the user on the registered recording medium 110.
[0119]
As described above, at the time when the user “decides” while “reserve” is informed, all the items that can be specified in the reservation mode have been specified. The broadcast date and time of the soccer program are registered in the recording / reproducing means 153, and a notification sound indicating that the setting of the recording reservation has been completed or a sound such as "recording reservation has been completed" is issued from the speaker 104. Then, upon receiving the notification that the reservation completion has been registered in the hierarchical shifting means 151, the in-tier processing means 152 returns to the soccer program list screen. Thus, the user can continue operations such as making a reservation for another program or searching for a program of another genre.
[0120]
Upon being notified that the reservation completion has been registered, the above-mentioned hierarchy shifting means 151 ends the above-mentioned operation guidance (FIG. 5, S511 → S513). At the same time as ending the operation guidance, the layer shifting means 151 outputs data corresponding to the notification sound indicating that the operation guidance has been completed to the notification means 106, and the notification means 106 notifies the notification sound. The hierarchy shifting unit 151 may output a voice guidance “Operation guidance has been completed” to the notification unit 106 following the notification sound.
[0121]
It should be noted that these notification sounds are distinguished from each other by a notification sound so that the completion of the operation guidance and the start of the operation guidance from a state in which the operation guidance is not started such as when the program navigation mode A is started can be distinguished. It is desirable to make the volume, frequency, tone, notification time, rhythm, melody sound, and the like different.
[0122]
In this way, the state of the digital TV 100 and what to do next are notified from the speaker 104 by the notification sound or the voice guidance, so that even if the user is a visually impaired person, the operation is not lost.
[0123]
In the above description, the event processing means 102 notifies the notification sound and the voice guidance only when "program navigation", "genre search", "sports", and "soccer" are received from the sound conversion means 101. However, even when “program navigation”, “genre search”, “sports”, and “soccer” are designated by the remote controller 300, the notification sound and the voice guidance may be notified.
[0124]
In the above description, the notification sound or the voice guidance notified from the speaker 104 is notified in each operation guide, but the content to be notified may be selected by the user. For example, when a predetermined mode of operation explanation is activated, or when a program is being reproduced on the monitor 103 or the speaker 104, and the user presses the notification content setting key 304 of the remote controller 300, the event processing unit 102 The notification that the notification content setting key 304 has been pressed is transferred to the accepting unit 111. Upon receiving the notification that the notification content setting key 304 has been pressed, the receiving unit 111 outputs data corresponding to the voice guidance “Please select the notification content.” To the notification unit 106. The notification means 106 notifies the voice guidance from the speaker 104.
[0125]
When the user hears the voice guidance, the user gives a notification content instruction such as “only the notification sound”, “only the voice guidance”, or “both” to the digital TV 100. The voice uttered by the user is converted into an electric signal by the voice conversion means 101 and received by the reception means 111 via the event processing means 102.
[0126]
For example, upon receiving a signal corresponding to “notification sound only”, the accepting unit 111 notifies the in-layer processing unit 152 of the signal. After receiving the notification, the in-hierarchy processing unit 152 outputs only the data corresponding to the notification sound to the notification unit 106, and does not output the data corresponding to the voice guidance to the notification unit 106.
[0127]
In the above description, a case has been described in which the user activates the program navigation mode A by saying “program navigation”. However, the user activates the program navigation mode A using the menu key 303 of the remote controller 300 to perform recording. You may make a reservation. For example, when a TV program is being reproduced on the monitor 103 and the speaker 104, a healthy person presses the menu key 303 when making a reservation for recording a soccer program. The fact that the menu key 303 has been pressed is transmitted from the remote controller 300 to the event processing means 102.
[0128]
When the notification that the menu key 303 has been pressed is transmitted, the event processing means 102 transfers the activation instruction and the fact that the instruction from the user has been directly received from the remote controller 300 to the hierarchy transition means 151 (FIG. 5, S531). ).
[0129]
When the start instruction is transferred, the hierarchy shifting means 151 starts the program navigation mode A (S501 in FIG. 5). However, when the program navigation mode A is activated by pressing the menu key 303, the hierarchy shifting unit 151 does not emit the notification sound as described above. Similarly, the in-hierarchical processing means 152 also waits for the user to specify an item displayed on the program navigation screen without informing the voice guidance (FIG. 5, S502 → S521). It is normal for a healthy person to activate the program navigation mode A using the menu key 303, and the normal person can see what he / she does by looking at the screen even if the notification sound and voice guidance are not notified. This is because it is possible to recognize the feeling.
[0130]
When the program navigation screen is displayed, the user presses the cursor key 301 in a predetermined direction of the remote controller 300 to move the pointer 521. The fact that the cursor key 301 has been pressed is transmitted from the remote controller 300 to the event processing means 102. The event processing means 102 transfers to the in-hierarchy processing means 152 that the received cursor key 301 has been pressed. The in-hierarchical processing means 152 grasps the position indicated by the current pointer 521 based on the fact that the transferred cursor key 301 is pressed. Then, the in-layer processing means 152 displays the pointer 521 at the grasped position.
[0131]
The user presses the enter key 302 when the pointer 521 moves to a desired item. The fact that the enter key 302 has been pressed is transmitted from the remote controller 300 to the event processing means 102. When the remote controller 300 transmits that the decision key 302 has been pressed, the event processing means 102 transfers the fact that the decision key 302 has been pressed to the intra-layer processing means 152 (FIG. 5, S534).
[0132]
When the event processing means 102 transmits that the decision key 302 has been pressed, the in-layer processing means 152 informs the above-mentioned hierarchy shifting means 151 that the user has designated the item currently pointed to by the pointer 521. Notice. The hierarchy shift unit 151 activates an operation guide corresponding to the notified item (FIG. 5, S522 → S523 → S524). Note that, in the reservation mode, when “reservation” is designated by pressing the enter key 302, the above-mentioned hierarchy shift unit 151 ends the operation guidance (FIG. 5, S522 → S523 → end).
[0133]
Even when the program navigation mode A is activated by the menu key 303 in this way, the hierarchical transition unit 151 can notify the digital TV 100 of the item to be activated instead of the cursor key 301 and the enter button 302, and May be activated. However, even if the predetermined operation guidance is activated using voice, if the program navigation mode A is activated by the menu key 303, the above-mentioned hierarchy shifting means 151 and the above-mentioned intra-hierarchy processing means 152 are notified by a notification sound. And data corresponding to the voice guidance are not notified to the notification means.
[0134]
When the visually impaired person activates the program navigation mode A using the menu key 303, the visually impaired person cannot grasp the item indicated by the pointer 521. Therefore, when the item pointed to by the pointer 521 changes, the in-hierarchical processing means 152 outputs the item pointed to by the pointer 521 to the notification means 106. The notification means 106 notifies the output item.
[0135]
Further, the pointer 521 may be moved by a user's voice instead of the cursor key 301. For example, when the program navigation screen is activated, the in-hierarchy processing means 152 displays a pointer 521 at a position indicating the program guide item 501. When the user says “below”, the “below” is received by the in-layer processing means 152 via the voice conversion means 101 and the event processing means 102. When receiving the lower part, the in-layer processing means 152 moves the pointer 521 to the counterprogram item 502 displayed immediately below the program guide item 501.
[0136]
Note that if it is assumed that even a visually impaired person is likely to operate the remote controller, even if the program navigation mode A is activated by pressing the menu key 303, the above-described hierarchy shifting means is used. 151 or the in-hierarchy processing means 152 may output data corresponding to the notification sound or the voice guidance to the notification means 106.
[0137]
Note that, instead of the remote controller 300, keys provided on a keyboard, a Braille keyboard, and the digital TV 100 may be used as the cursor key 301, the enter key 302, the menu key 303, the notification content setting key 304, and the notification speed setting key 307. .
[0138]
【The invention's effect】
Since the electronic device of the present invention notifies the operation guidance at a volume higher than the program audio, the operation guidance is not erased by the program audio or the like. Can be. Therefore, an electronic device with high usability can be provided from the viewpoint of universal design.
[0139]
In addition, since the operation guide can be reliably heard, not only visually impaired persons but also healthy persons can easily operate the electronic device without looking at the screen.
[0140]
Further, since the user can change the notification speed of the guide item notified by the operation guide, the time during which the guide item is notified can be shortened by increasing the notification speed.
