  Embodiments of the present invention will be described below with reference to the drawings. However, such an embodiment does not limit the technical scope of the present invention.

  FIG. 1 is a diagram showing a configuration example of an information display system in an embodiment of the present invention. The display system in the present embodiment is a computer system mounted on an automobile and may be shared with a navigation system. In FIG. 1, a display system 10 detects, on a control device 11, a display 12 for displaying information (contents) on the Internet, for example, an operation panel 13 constituted by a touch panel, a speaker 14 for outputting sound, and sound. And a communication device 16 connectable to the Internet.

  The control device 11 is a general-purpose computer device equipped with a CPU, a memory, and a hard disk drive (storage device). A browser (Internet browsing program) as a display control means for displaying information on the Internet on a display, and converts the information into sound. And a speech recognition program for recognizing a user's voice instruction and the like are executed. All components related to voice output, such as the microphone 15, the speaker 14, a voice synthesis program, and a voice recognition program, constitute voice output means.

  In the information display system 10 having such a configuration, in the first embodiment, information acquired from the Internet is displayed on the display 12 and the acquired information is read out by voice. At that time, when all the information cannot be displayed on the display, the screen is automatically scrolled according to the reading so that the read-out information is displayed on the display 12.

FIG. 2 is a flowchart showing processing in the first embodiment. FIG. 3 is a diagram for explaining processing in the first embodiment. With reference to FIG. 3, it demonstrates along FIG. In FIG. 2, when information is acquired from the Internet via the communication device 16 (S10), this process is started, and the information acquired by the browser function of the control device 11 is displayed on the display 12 (S11). At this time, if the display area of the acquired information is larger than the screen area of the display 12, a scroll button is displayed, and the user operates the scroll button to scroll the screen, thereby displaying the information to be displayed on the screen. Can be moved sequentially.

  Text data (character string) in the acquired information is converted into voice data by the voice synthesis function of the control device 11 (S12), and reading of the voice data by the voice reading function is started (S13). During reading, the position on the screen where the character being read is displayed is obtained (S14). When the display position of the displayed character on the screen is determined from the screen size and the display character size of the display 12 and displayed in horizontal writing, as shown in FIG. If you go from left to right on the top line and go to the right on that line, you will move to the bottom line and read from left to right as well.

  Then, the display position of the character being read out is sequentially acquired, and it is determined whether or not the position is above a predetermined position on the screen (S15). Further, it is determined whether or not the last character of the information to be read out is displayed on the screen (S16). When the final character is displayed on the screen, as described below, it is not necessary to scroll the screen so that the read-out character is displayed. Therefore, scrolling is not performed, and the completion of the read-out is determined (S18). When the reading is complete, the process ends.

  The predetermined position in step S15 is, for example, the position of the center line M in the horizontal line of the screen (see FIG. 3B). When the final character is not displayed in step S16, if the display position of the read-out character is below the predetermined position (center line) M, the read-out character is above the predetermined position (center line) M. Thus, the browser automatically scrolls (S17). After scrolling the predetermined line, the process returns to step S14, the display position of the read-out character is calculated, and the process is continued.

  The amount of scrolling may be one line or a plurality of lines. For example, when the scroll amount is one line, when the read-out character moves to the character in the line immediately below the center line, it is scrolled by one line and becomes a line immediately above the center line. Therefore, every time one line is read out, the line is scrolled by one line. When the scroll amount is two lines, similarly, every time two lines are read out, two lines are scrolled.

  As an example, the predetermined position is the center line in the horizontal line. By doing so, the character to be read out is always near the center of the screen, and is the position most easily seen by the user. From the beginning of reading, until the reading position reaches near the center, the reading character is above the center line, so scrolling is not performed and the reading character is displayed when the final character is displayed on the screen. Even if is lower than the center line, all the remaining read-out characters are displayed on the screen, so scrolling is not performed (see FIG. 3C). Of course, scrolling may be performed so that the read character comes near the center line until the final character is read.

  As described above, in the first embodiment, when all the information cannot be displayed on the display, the screen is automatically displayed according to the reading so that the information read out is displayed on the display 12. Since scrolling is performed, the user can always display the characters being read out on the screen without manually scrolling.

Next, in the second embodiment, the browser function of the control device 10 has a function of displaying only a headline that is a headline with a link on the display for the search result of the Internet search engine.

  FIG. 4 is a diagram for explaining a second embodiment. Usually, when a desired keyword is entered in a keyword input field of an Internet search site (portal site) and a search is executed, a plurality of sites are extracted as search results, and as shown in FIG. Detailed text including linked headlines and keywords for each site appears on the display. Clicking on the linked text display will take you to that site.

  A search result is composed of a headline with a link corresponding to each site and its detailed text, and a plurality of lines are required to display it. On the other hand, since the size of the display in the information display system mounted in the automobile is relatively small, many search results cannot be displayed.

  Therefore, in the second embodiment, when the browser function of the control device 10 receives the search result information including the extracted headline with links for each of a plurality of sites and the detailed text thereof, FIG. As shown in Fig. 4, only the headline with link is displayed without displaying the detailed text. Thereby, more search result sites can be displayed on the screen, and the listability is improved.

  FIG. 5 is a flowchart showing processing in the second embodiment. When the browser function of the control device 11 receives search result information having a plurality of search results each composed of a headline with a link and a detailed text (S20), this process is started and a link is added from the received information. Only the headline is extracted (S21) and displayed (S22). Specifically, in the search result information composed of an HTML document, a character string to which a site address is attached as a link is determined as a headline, and is extracted.

  Preferably, the detailed text that is not displayed may be converted into voice data by the voice synthesis function of the control device 11 (S23), and reading of the voice data by the voice reading function may be started (S24). Thereby, it is possible to know the contents of the detailed text that is not displayed. If there is more than one search result, you can insert a silence for a few seconds between reading the detailed text of each search result in order to recognize the delimiter of the detailed text of each search result. The display color of the headline corresponding to the detailed text may be different from the color of other headlines.

  Furthermore, a number may be added to the linked headline displayed as a search result, and the detailed text may be read out after reading out the number (see FIG. 4B).

  Further, the voice type may be changed for each search result and read out. For example, the voice synthesis function has sound quality data for male voices and sound quality data for female voices, and the sound quality of detailed texts read out sequentially is switched alternately between male voices and female voices for each search result site. It may be. Thereby, it becomes possible to easily recognize the break of the site in reading out the detailed text.

  Furthermore, in the third embodiment, when the browser function of the control device 11 acquires search result information, the browser function of the control device 11 automatically transitions to each link destination site included in the search result information, and the text data of that site is voiced. Read aloud.

  FIG. 6 is a flowchart showing processing in the third embodiment, and FIG. 7 is a diagram for explaining the processing. A description will be given along FIG. 6 with reference to FIG.

  When the browser function of the control device 11 receives search result information having a plurality of search results each composed of a headline with a link and detailed text (S30), this process is started and the search result information is once displayed. (S31). At this time, only a headline with a link may be displayed as in the second embodiment (see FIG. 7A). After that, it automatically transitions to the first search result site (S32) (see FIG. 7B).

  When the transition is made to the first search result site, the speech synthesizing function of the control device 10 converts the text data of the transitioned site into speech data, and reading of the speech data is started by the speech reading function (S33).

  While the search result site is being read out by voice data, the browser function waits for an operation from the user (S34). User operations include, for example, (1) “stop” operation to stop reading and maintain the display screen as it is currently displayed, (2) “return” operation to return to the previous display screen, (3) For example, the “next” operation to move to the next site. These operations may be input signals from the operation panel 13 or audio signals from the microphone 15. In the case of operation by voice input, for example, the user utters “stop”, “return”, “next”, etc., recognizes the operation content of the voice signal input from the microphone by the voice recognition function, and the browser function Performs the corresponding operation. In the case of the “stop” operation (S341), the reading of the audio data is stopped, and the display screen remains at the currently displayed site (S342). In the case of the “return” operation (S343), the reading of the voice data is stopped, and the screen before the transition is returned (S344). In the case of “next” (S345), the process proceeds to the next search result site as described in the following step S36.

  Further, the site displayed as a search result may be displayed with an identification code (for example, a numeric number), and the user may be able to input a site number or the like that the user wants to see. The number may be input from a number button (such as a numeric keypad) on the operation panel 13 or may be input from the microphone 15 by voice.

  When a number is input (S346), the presence / absence of the number is determined. If there is a number, a transition is made to the site corresponding to the number (S347), and the text data of the site is read out by voice (S33).

  When there is no user operation while the voice data is being read and the reading of the text data of the displayed site is completed (S35), the browser function refers to the search result information and the next search result site is displayed. Whether there is a next search result site is determined (S36), and if there is a next search result site, a transition is made to the next site (S37). Then, as described above, the text data of the next site is converted into voice data, and reading of the voice data is started (S33). If there is no next search result, the screen returns to the search result information display screen (S31).

  When the reading of the text data in step S35 ends, for example, when all the text data of the site has been read, a predetermined reading time (several tens of seconds) is set in advance, and when that time has passed, the user This is the case when the operation has interrupted.

In the third embodiment, similarly to the second embodiment, when a site displayed as a search result is numbered and displayed, and when the transition to the search result site and reading its contents, You may make it read out the text of the site after reading the number attached. Further, the voice type may be changed for each search result and read out. For example, the voice synthesis function has sound quality data for male voices and sound quality data for female voices, and the type of voice to be read out is switched alternately between male voices and female voices for each sequentially transitioning site. May be.

  Further, in the second embodiment and the third embodiment, the tone of the voice may be changed according to the attribute of the text data to be read out. For example, when reading out the detailed text in the search result information, the reading volume of the text corresponding to the keyword is changed (for example, increased), the reading speed is changed (for example, slowed down), or the reading tone is changed (for example, You may make it raise. Also, depending on the type of audio data to be read, such as the body text (text) of the transition destination site, a headline with a link, or its detailed text, the volume, speed, tone, etc. Etc. may be changed. Since you cannot see the display screen while driving, if you read it monotonously with the same voice quality, it is difficult for the driver to recognize where you are reading, but you can see the screen by changing the tone of the voice you are reading In addition, the attribute (type) of the text data being read out can be recognized, which contributes to driving safety.

  Each of the above-described embodiments is optimal for an information display system mounted on a vehicle such as an automobile. However, the present invention is not limited to this, and is not limited to this. Is also applicable.
