Next, Figure 4 is described.

FIG. 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

Fig. 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display (180).

The user can move the remote control device (200) up and down, left and right, or rotate it. The pointer (205) displayed on the display (180) of the display device (100) corresponds to the movement of the remote control device (200). This remote control device (200) can be called a space remote control because the pointer (205) moves and is displayed according to the movement in 3D space, as shown in the drawing.

Figure 4 (b) exemplifies that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display (180) of the display device (100) also moves to the left correspondingly.

Information about the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the display device (100). The display device (100) can calculate the coordinates of the pointer (205) from the information about the movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.

Figure 4 (c) illustrates a case where a user moves the remote control device (200) away from the display (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display (180) corresponding to the pointer (205) can be zoomed in and displayed in an enlarged manner.

Conversely, when the user moves the remote control device (200) closer to the display (180), the selection area within the display (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced size.

Meanwhile, when the remote control device (200) moves away from the display (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selection area may be zoomed in.

In addition, when a specific button within the remote control device (200) is pressed, recognition of up, down, left, and right movements can be excluded. That is, when the remote control device (200) moves away from or toward the display (180), up, down, left, and right movements are not recognized, and only forward and backward movements can be recognized. When a specific button within the remote control device (200) is not pressed, only the pointer (205) moves according to the up, down, left, and right movements of the remote control device (200).

Meanwhile, the movement speed or movement direction of the pointer (205) can correspond to the movement speed or movement direction of the remote control device (200).

Meanwhile, the pointer in this specification means an object displayed on the display (180) in response to the operation of the remote control device (200). Accordingly, objects of various shapes other than the arrow shape illustrated in the drawing are possible as the pointer (205). For example, it may be a concept including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer (205) may be displayed corresponding to one point of the horizontal and vertical axes on the display (180), and may also be displayed corresponding to multiple points such as lines and surfaces.

Meanwhile, the display device (100) according to an embodiment of the present disclosure obtains and displays content to be displayed as a result of a search or recommendation, and at this time, the content to be displayed as a result of a search or recommendation may vary depending on the type of disability determined based on the setting information of the menu.

The controller (170) can change the type, order, display method, etc. of the content to be displayed as a result of a search or recommendation by filtering the content to be displayed as a result of a search or recommendation according to the disability type determined based on the setting information of the menu. For example, the controller (170) can preferentially display the filtered content according to the disability type determined based on the setting information of the menu, display only the filtered content, or display the filtered content separately from the remaining content. This will be described in detail below.

FIG. 5 is a flowchart illustrating a method of operating a display device according to an embodiment of the present disclosure.

The controller (170) can obtain a content search or content recommendation signal (S10).

The controller (170) can detect input of a search word and selection of a search button through a search window for searching content, and can obtain a content search signal accordingly.

And, the controller (170) can obtain a content recommendation signal by receiving a content recommendation command from a user. Or, the controller (170) can obtain a content recommendation signal for displaying recommended content in at least one area when accessing a home screen, etc.

When the controller (170) obtains a content search signal or a content recommendation signal, it can obtain menu setting information (S20).

When the controller (170) obtains a content search signal or a content recommendation signal, it can search or recommend content according to the user's disability type.

According to one embodiment, the controller (170) can obtain setting information of the menu to determine the viewer's disability type.

The menu may include items for setting various functions executable on the display device (100). For example, the menu may include at least one of an item for setting a subtitle function and an item for setting a voice guidance function.

FIG. 6 is a drawing illustrating an example of a menu provided by a display device according to an embodiment of the present disclosure.

The controller (170) can control the display (180) to display a menu. The display (180) can display a menu including at least one of an item for setting a voice guidance function and an item for setting a subtitle function.

In the example of Fig. 6, the 'Read menu by voice' item may be an item for setting the voice guidance function, and the 'Subtitle' item may be an item for setting the subtitle function.

The voice guidance function may refer to a function that provides voice guidance for menu names or operations so that the display device (100) can be used without directly looking at the screen.

The subtitle function can refer to a function that provides text guidance so that you can watch content without hearing the sound directly.

The controller (170) receives a command to set the voice guidance function to 'use' or 'disable' through the menu, and can set the voice guidance function on or off according to the received command.

Likewise, the controller (170) can receive a command to set the subtitle function to 'use (on)' or 'disable (off)' through the menu, and can set the subtitle function to on or off according to the received command.

The setting information of the menu may include at least one of the setting status of the voice guidance function and the setting status of the subtitle function.

That is, when the controller (170) obtains the setting information of the menu, it can obtain whether the voice guidance function is on or off and whether the subtitle function is on or off.

When the controller (170) obtains a content search signal or a content recommendation signal, it can obtain at least one of whether the voice guidance function is turned on and whether the subtitle function is turned on.

Again, let's explain Figure 5.

The controller (170) can determine the type of failure based on the setting information of the menu (S30).

Specifically, the controller (170) can obtain whether the user has either a hearing impairment or a visual impairment based on the setting information of the menu. That is, the controller (170) can determine the user's disability type based on the setting information of at least one of the subtitle function and the voice guidance function in the menu.

For example, the controller (170) may determine that the user is visually impaired if the voice guidance function is set to on. Additionally, the controller (170) may determine that the user is hearing impaired if the subtitle function is set to on.

Meanwhile, the controller (170) can determine that the user does not have any type of disability, either visual or hearing impairment, if both the voice guidance function and the subtitle function are off. That is, the controller (170) can determine that the user does not have any type of disability, if both the voice guidance function and the subtitle function are off.

The controller (170) can filter content based on the disability type (S40) and display the filtered content (S50).

That is, the controller (170) can filter content based on the setting information of the menu. More specifically, the controller (170) can filter content to be displayed as a result of search or recommendation according to the type of disability determined based on the setting information of the menu. The controller (170) can filter content to be displayed as a result of search or recommendation based on the setting information of at least one of the subtitle function and the voice guidance function in the menu.

Additionally, the controller (170) can sort the filtered content according to popularity or user viewing history.

Below, we will explain in detail how to filter content based on the settings information of various menus.

The controller (170) can display content in order of accuracy or popularity when the user does not have any disability type. For example, when the controller (170) receives a content search signal, the controller can display content in order of search terms and accuracy, or when recommending a content recommendation signal, the controller can display content in order of popularity.

That is, the controller (170) can display content in order of accuracy or popularity when both the voice guidance function and the subtitle function are off.

The controller (170) can preferentially display content with subtitle support when the user is hearing impaired. That is, when the subtitle function is set to on in the menu, the controller (170) can preferentially display content with subtitle support.

Specifically, the controller (170) may filter the content with subtitles to be displayed as a result of a search or recommendation when the subtitle function is turned on in the menu. For example, when the controller (170) obtains a content search signal, the controller (170) may search for content corresponding to a search word and then filter the content with subtitles from the searched content. As another example, when the controller (170) obtains a content recommendation signal, the controller (170) may obtain content to be recommended in order of popularity or latest and then filter the content with subtitles from the obtained content.

When displaying search or recommended content, the controller (170) may display content with subtitles as a priority according to filtering, and display the remaining content after the content with subtitles.

And, more specifically, the controller (170) can further filter the content based on the language set in the subtitle function. The controller (170) can first filter the content for which subtitles are supported in the search or recommended content, and secondarily filter the content for which subtitles are supported in the language set in the subtitle function among the first-filtered content. Accordingly, when displaying the search or recommended content, the controller (170) can first display the content for which subtitles are supported in the language set in the subtitle function, then display the content for which subtitles are supported in a language not set in the subtitle function, and then display the content for which subtitles are not supported.

The controller (170) can preferentially display content that supports voice screen description when the user is visually impaired. That is, when the voice guidance function is set to on in the menu, the controller (170) can preferentially display content that supports voice screen description.

Content that supports voice screen description may refer to content that provides voice descriptions for each scene as well as the dialogue of characters when the content is played.

Specifically, the controller (170) may filter content that supports voice screen description to be displayed as a result of a search or recommendation when the voice guidance function is set to on in the menu. For example, when the controller (170) obtains a content search signal, the controller (170) may search for content corresponding to a search word and then filter out content that supports voice screen description from the searched content. As another example, when the controller (170) obtains a content recommendation signal, the controller (170) may obtain content to be recommended in order of popularity or latest and then filter out content that supports voice screen description from the obtained content.

When displaying search or recommended content, the controller (170) may preferentially display content that supports voice screen description according to filtering, and display the remaining content after the content that supports voice screen description.

And, more specifically, the controller (170) may further filter the content based on the language set in the voice guidance function. The controller (170) may first filter the content for which voice screen description is supported in the search or recommended content, and secondarily filter the content for which voice screen description is supported in the language set in the voice guidance function among the first-filtered content. Accordingly, when displaying the search or recommended content, the controller (170) may first display the content for which voice screen description is supported in the language set in the voice guidance function, then display the content for which voice screen description is supported in a language not set in the voice guidance function, and then display the content for which voice screen description is not supported.

Meanwhile, the display device (100) according to the embodiment of the present disclosure can filter content that supports subtitles or content that supports audio screen description using metadata. For example, the controller (170) can filter content that supports subtitles or content that supports audio screen description based on at least one of content provider (CP) metadata and electronic program guide (EPG) metadata.

FIG. 7 is a schematic diagram illustrating a method for a display device to filter content using metadata according to an embodiment of the present disclosure.

The display device (100) communicates with a server (20), and the server (20) can communicate with at least one of a content provider (30) and an EPG provider (40).

A content provider (30) can provide content to a server (20) and provide CP metadata together with the content. The CP metadata can include information on whether subtitles and voice screen descriptions are supported for each content provided by the content provider.

An EPG provider (40) can provide EPG for broadcast content to a server (20) and provide EPG metadata together with the EPG. The EPG metadata can include information on whether subtitles are supported for each broadcast content and whether voice screen description is supported.

The server (20) can receive at least one of content and CP metadata from a content provider (30), or at least one of EPG and EPG metadata from an EPG provider (40).

The server (20) may include at least one of a metadata acquisition/management platform, a recommendation platform, a search platform, and a customer usability log.

The metadata acquisition/management platform acquires information on accessibility support from the content provider (30) and the EPG provider (40), and this can be used to manage information on each content in the server (20). The metadata acquisition/management platform can acquire, store, and manage at least one of the CP metadata received from the content provider (30) and the EPG metadata received from the EPG provider (40). The metadata acquisition/management platform can manage information on subtitle/audio screen description for each content. The metadata acquisition/management platform can store information on whether at least one of the subtitle or audio screen description is supported and the supported language.

The recommendation platform can obtain at least one recommended content based on metadata managed in the metadata acquisition/management platform.

The search platform can acquire at least one search content based on metadata managed in the metadata acquisition/management platform.

Customer usability logs can store and manage records of content viewed by customers, functions used by customers, etc. For example, customer usability logs can include menu setting information for each user.

The recommendation platform and search platform can identify targeting segments based on whether/what accessibility settings are enabled based on customer usability logs when obtaining at least one recommendation content or search content.

For example, the recommendation platform and search platform can identify content that supports at least one of subtitles or audio screen description based on menu setting information for each user.

The recommendation platform and the search platform can provide at least one recommendation content or search content to the display device (100). The recommendation platform and the search platform can provide information on whether subtitles or voice screen descriptions of each recommendation/search content are supported along with one recommendation content or search content.

Alternatively, the recommendation platform and search platform may provide the support content of subtitles or voice screen descriptions as recommended/searched content to the display device (100) upon request of the display device (100). That is, the recommendation platform and search platform may extract accessibility support content for each target segment and provide it to the display device (100).

The display device (100) may receive information from the server (20) on whether subtitles or voice screen descriptions are supported, and select content to be recommended or searched, or may directly receive content to be recommended or searched from the server (20). That is, filtering of content to be recommended or searched according to setting information of the menu may be performed by the server (20) and transmitted to the display device (100), or filtering may be performed directly by the display device (100).

FIG. 8 is a diagram illustrating an example of a method for a display device to display recommended content according to an embodiment of the present disclosure.

The screen shown in Fig. 8 may be an example of a screen that displays recommended content. For example, the controller (170) may display recommended content in at least one area when displaying the home screen. At this time, the controller (170) may display closed caption-supported content as recommended content based on information that the subtitle function is set to on in the menu. Closed captioning may mean a service that broadcasts all voice content in real time as text for the hearing impaired.

Meanwhile, the screen of Fig. 8 is only an example screen when only the subtitle function is set to on in the menu. If the voice guidance function is set to on in the menu, the controller (170) can display content that supports voice screen description as recommended content.

FIG. 9 is a diagram illustrating an example of a method for a display device to display search content according to an embodiment of the present disclosure.

The screen shown in Fig. 9 may be an example of a screen that displays search content. When the controller (170) receives a command to search for content related to a specific search word, the controller (170) may display the search content in at least one area. At this time, the controller (170) may display content that supports voice screen description as search content based on information that the voice guidance function is set to on in the menu.

In addition, the controller (170) may further display content that does not support voice screen description after content that supports voice screen description. The controller (170) may sort content based on accuracy with the search word even within content that supports voice screen description, and may also sort content based on accuracy with the search word even within content that does not support voice screen description.

Meanwhile, the screen of Fig. 9 is only an example screen when only the voice guidance function is set to on in the menu. If the subtitle function is set to on in the menu, the controller (170) can display closed caption-supported content as search content.

FIG. 10 is a diagram illustrating an example of a method for a display device to display recommended content according to another embodiment of the present disclosure.

According to another embodiment of the present disclosure, the controller (170) may filter the recommended or searched content based on whether the subtitle function or voice guidance function is turned on, as well as the type of language set for the subtitle function or voice guidance function when displaying the recommended or searched content.

Specifically, the controller (170) can receive an input for selecting a language type (e.g., Korean, Japanese, English, etc.) of the subtitle or voice guidance when the subtitle or voice guidance function is turned on. The controller (170) can recognize the set language type as the user language. The controller (170) can filter out content whose supported language matches the user language among the content for which subtitle or voice screen description is supported, and display it in a separate category or display it with priority.

Referring to the example of FIG. 10, the controller (170) may display closed caption supported content as recommended content based on the on-setting information of the subtitle function, and may display content whose subtitle support language matches the user-set language among the closed caption supported content separately from other content.

In this way, according to various embodiments of the present disclosure, when providing content to a user with hearing or visual impairment through a search/recommendation service, the display device (100) can classify/select content appropriate for viewing by considering each disability and display the results at the top.

In summary, the controller (170) supports subtitle services within a program, and if the subtitle language is a language set by the user, it can distinguish it and display the results as a separate category, and can obtain whether closed captions are provided within the VOD and EPG of each CP. Similarly, the controller (170) can distinguish it and display the results as a separate category if the voice screen description function exists within the program, and if the voice language is a language set by the customer, it can obtain whether voice screen descriptions are provided within the VOD and EPG of each CP.

According to one embodiment of the present invention, the above-described method can be implemented as a processor-readable code on a medium in which a program is recorded. Examples of the processor-readable medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.

The display device described above is not limited to the configuration and method of the embodiments described above, and the embodiments may be configured by selectively combining all or part of the embodiments so that various modifications can be made.
