Description

  The present invention relates to a user interface design method for a content navigation service in a portable terminal capable of transmitting and receiving at least one of a broadcast wave and a communication wave.

  As a content viewing service, (1) a service that provides content that is played while streaming via communication, or a content that is downloaded and viewed at any time via communication, and (2) a service that provides content that is viewed while streaming via broadcast waves (3) It is conceivable to provide a service for providing content to be viewed and received in advance through a communication network or broadcast wave. In addition, in order to take advantage of the advantage of the portable terminal that it can be carried and viewed anytime and anywhere, the terminal can receive and store metadata associated with the content in advance, and a search engine can also be provided in the terminal. Conceivable. In such a service, metadata is stored in the mobile terminal and a part of the content can be stored. Therefore, the user can receive the advantage that the user can search and view the content anytime and anywhere.

  In the above service, when a user performs a search using a conventional user interface or a conventional search engine, broadcast wave streaming content is included in the search result list even if the broadcast wave reception intensity is insufficient Is presented to the user in the list state as it is. In this case, even if the user tries to view the broadcast wave streaming content with interest, the content cannot be reproduced because the content cannot be received due to the radio wave condition. Therefore, usability is reduced.

  A similar problem occurs when the user tries to display an arbitrary content list on the screen. In the conventional user interface, even when the radio wave reception intensity of the broadcast wave is insufficient, the broadcast wave streaming content information is displayed as a content list, and usability is reduced for the same reason as described above. Also, if content information that cannot be viewed right now (cannot be played back) due to insufficient reception strength is presented, it is difficult for the user to select content that can actually be viewed from the search results or list screen. In this respect, usability is reduced. As a merit of the portable terminal, in order to realize the above-mentioned “contents can be viewed anytime and anywhere”, it is necessary to appropriately present content information that can be viewed immediately to the user.

  There has been proposed a method in which display priority is adjusted according to terminal status, content attributes, recommendation level, etc., and the sorted content is displayed to the user (see, for example, Patent Document 1). However, this proposed technology does not take into consideration the user interface design according to the radio wave environment (reception strength), the storage state of the content, and the difference between the mobile phone of the download type and the streaming type.

  As another known technique, a wireless communication terminal has been proposed that reduces power consumption when the reception environment deteriorates in one-to-many unidirectional communication such as broadcast broadcasting and multicast communication (see, for example, Patent Document 2). In this proposed technology, the terminal presets the threshold of the reception radio wave environment set for each content transmission rate, compares the threshold corresponding to the transmission rate of the content to be received with the current reception radio wave environment, If the current reception environment is less than or equal to the threshold value, the user is notified so that the user can select whether or not to execute reception, or the user can move to a place with a good radio wave environment during the scheduled reception time of content. Warn in advance. With this method, it is possible to avoid the reception of content that may fail to be received in advance, but for convenient content navigation that takes into account the content storage status, radio wave intensity, distribution form, etc. in the mobile terminal Is not touched.

It is a figure which shows the process flow of the user interface design (priority display control) by embodiment, and is a figure which shows the process following FIG. 14A.

  Hereinafter, specific user interface design will be described with reference to the drawings. FIG. 1 is a schematic block diagram of a wireless portable terminal 200 provided with a user interface design device 250. The user interface design device 250 realizes highly convenient content navigation in a wireless portable terminal (hereinafter simply referred to as “portable terminal” or “wireless terminal”) 200. The portable terminal 200 includes a broadcast interface and a cellular communication interface. It is assumed that both content broadcasted by broadcast waves and content distributed by communication can be received.

  The user interface design refers to a design of a part related to a user's receiving method and interaction (interaction) in designing a computer, a communication device, a software application, and the like. In user interface design, it is an important goal to enable users to use devices and application software as intuitively and easily as possible.

  A UI (user interface) control unit 203 constituting the user interface design device 250 acquires a content search result list in which scores are assigned to each content by the search engine 205 inside the mobile terminal 200. Alternatively, a content list in which a score is assigned to each content is acquired by automatic distribution of the content via a communication network. The “score” is a value that serves as a rough indication of priority in a content list provided by search or communication network, and a specific example thereof will be described later.

  The UI control unit 203 receives content storage state information from the content / metadata management unit 208. The content storage state is information indicating whether each content is already stored in the mobile terminal 200 or not stored. On the other hand, the reception intensity calculation unit 204 calculates the reception radio wave intensity of the broadcast wave received by the broadcast reception unit 207 of the mobile terminal 200 and the communication signal obtained via the communication control unit 206. In addition, in the example of FIG. 1, although it has the structure which performs both wireless communication and broadcasting, it is good also as a structure which performs only any one.

  As a part of user interface design, the UI control unit 203 performs rearrangement control of the list display so that the obtained search result and content list become a list that is easy to use for the user of the mobile terminal 200. To achieve this, the score value assigned to each content depends on the storage state of each content and the reception intensity (radio wave environment) of at least one of the broadcast wave and communication wave received by the mobile terminal 200 Apply adjustment values to determine the order of listing. Further, for the content distributed in streaming, the display priority is determined in consideration of the moving speed of the mobile terminal 200 and the content length.

In order to adjust the list display according to the radio wave environment, the UI control unit 203 has a first score adjustment function for adjusting the score value of the content using the reception intensity as an argument. As a specific example of the first score adjustment function, an adjustment function F (SNa) used for adjusting the list display of communication contents according to the SN ratio of communication waves, and a list display adjustment of broadcast contents according to the SN ratio of broadcast waves The adjustment function G (SNb) used for the above is stored in the memory. As will be described later, in the embodiment, since a method of subtracting the values of F (SNa) and G (SNb) from the score value is adopted, these functions are referred to as deduction functions, and the obtained adjustment value is the first score. This is called a deduction point value. Specific contents of the functions F (SNa) and G (SNb) will be described later.
The UI control unit 203 also has a second adjustment function P (R, L) used for display adjustment of content that is distributed in a streaming manner. Here, R is the moving speed of the mobile terminal 200, and L is the content length L of the ST content. The UI control unit 203 acquires the moving speed R of the portable terminal 200 from the moving speed sensing unit 202 and acquires the content length L of each content from the content / metadata management unit 208. With the second adjustment function, appropriate display adjustment based on the moving speed of the mobile terminal 200 and the content length can be performed. In the embodiment, since the method of adjusting the score value by subtracting the second adjustment function value is adopted, the second adjustment function is referred to as a second deduction function, and the obtained adjustment value is referred to as the second score deduction. This is called a value.
The UI control unit 203 uses the first adjustment function in consideration of the storage state of the content, and also determines the display order of the list using the second adjustment function when there is streaming content. Change. Then, thumbnail data of each content is acquired from the content / metadata management unit 208, and a search result list or a content list is displayed on the drawing / screen display unit 201 of the mobile terminal 200 according to the determined display order. When instructing the drawing / screen display unit 201 to display a thumbnail of the search result / content list, the user can see the distribution status of the current content at a glance by referring to the time information provided from the time control unit 209. It is desirable to perform display control. The thumbnail is an example of identification information for identifying content included in the content list, and the content name may be displayed instead of the thumbnail or together with the thumbnail. Details of the thumbnail display will be described later.

It is assumed that the user makes a search request on the portable terminal 200 provided with such a user interface design device 250. The UI control unit 203 sends a search request to the search engine 205 based on the search condition input by the user. The search engine 205 executes a search based on the metadata acquired from the content / metadata management unit 208. For example, assume that the user inputs the keyword “golf” as a search condition. Of course, the search condition may be a keyword other than “golf”, and the search may be performed based on conditions such as a genre instead of the keyword. The metadata includes information such as content introduction information, content distribution method, content length, and distribution date and time. As a delivery method, there are the following four patterns.
(1) Broadcast wave ST: Content distributed by streaming using a broadcast wave. The date and time to be aired is predetermined.
(2) Broadcast wave FC: Content distributed by file casting (download type) using broadcast waves. The delivery date and time is determined in advance.
(3) Communication network ST: Content distributed by streaming via the communication network. If the communication strength is stable, streaming viewing is possible at any time triggered by a user.
(4) Communication network FC: Content distributed by file casting (download type) via the communication network. If the communication strength is stable, it can be downloaded at any time triggered by the user.

  The search engine 205 outputs a list 290 as shown in FIG. 2 as a result of the search. In the list 290 of FIG. 2, a score is assigned to each searched content, and a distribution method is associated with the content. The score is a value obtained by an arbitrary calculation method using a normal search engine. In the embodiment, for the word “golf”, which is the search condition input by the user, a full text search is performed in the metadata of each content, and the number of words “golf” included in the metadata is obtained. In the example of FIG. 2, nine contents are shown for convenience, but in practice, any number of contents may be used according to the search result. Here, only those broadcasted at the time of the search date are picked up from broadcast ST. The broadcast date and time is described in the metadata.

  The conventional search display method is the process so far. In other words, the content IDs 002 and 005 are merely excluded because the scores are presented to the user in descending order of score values among those having a score greater than 0.

  However, depending on the radio wave state of the broadcast wave and communication wave, there is a high possibility that content that cannot actually be viewed is included in the list. Therefore, in the embodiment of the present invention, the following processing is further performed.

  First, the UI control unit 203 refers to the content / metadata management unit 203, and saves the contents of the broadcast FC and communication FC, which are download-type content (filecasting distribution), in the mobile terminal 200. Confirm. As a result, it is determined that the content IDs 004, 008, and 009 are not stored. Among these, the content of ID008 is broadcast wave content, and since the distribution time zone is determined, it is excluded from the search result list displayed to the user. On the other hand, IDs 004 and 009 are not stored at the present time, but can be downloaded at any time as long as the communication radio wave intensity is stable.

  The list in FIG. 2 acquired by the search engine 205 as a result of the adjustment by the score and the adjustment by the storage state is rewritten to the list 300 in FIG. 3 by the UI control unit 203.

Further, an S / N ratio (signal-to-noise ratio) is acquired and calculated as the radio wave intensity of the communication wave. This is designated as SNa. In addition, an S / N ratio (signal-to-noise ratio) is acquired and calculated as the radio wave intensity of the broadcast wave. This is designated as SNb. Then, according to the values of SNa and SNb, the following subtraction (deduction) processing is performed on the retrieved score.
・ For communication contents
Priority [ID] = Score [ID]-F (SNa) (1)
・ For broadcast content
Priotity [ID] = Score [ID] − G (SNb) (2)
here,
Priority [ID] is an evaluation value indicating the priority for display to the user,
Score [ID] is the score value assigned to the searched content,
ID is the content ID,
F (x) is a score deduction function according to the communication reception intensity, and a deduction function using the SN ratio [dBm] of the communication wave as an argument x,
G (y) is a score deduction function according to the broadcast reception intensity, and a deduction function using the SN ratio [dBd] of the broadcast wave as an argument y,
It is. In the embodiment, F (x) is a non-increasing function with respect to x, and G (y) is a non-increasing function with respect to y. By using G (y) as a function that does not increase with respect to the reception intensity, the display priority of the broadcast content is lowered as the broadcast reception intensity decreases. Avoid presenting content that cannot be seen right away to the user in places where the broadcast reception intensity is low. Thereby, it becomes easy for the user to search for content, and usability can be improved.

In the embodiment, the following function is defined as an example, but any other appropriate function may be selected.
F (x) = 100 (x ≦ −100)
F (x) = 10 (−100 <x ≦ −90)
F (x) = 5 (-90 <x ≤ -85)
F (x) = 1 (−85 <x ≦ −75)
F (x) = 0 (−75 <x)
G (y) = 100 (y ≤ -30)
G (y) = 10 (-30 <y ≤ -22)
G (y) = 3 (−22 <y ≦ −15)
G (y) = 0 (−15 <y)
Assume that SNa = −80 [dBm] and SNb = −20 [dBd]. When applied to the above calculation formula, since the content ID 001 is a content of communication ST distribution, formula (1) is applied. Since Score [ID] of the content ID 001 is 1, and F (SNa) = F (−80) = 1, Priority [001] = 1−1 = 0. When calculation is performed for each content listed in the list 300 of FIG. 3, the table 400 of FIG. 4 is created from the list 300 of FIG. The above calculation is applied only to content that has not been saved. This is because the quality of the stored one is not affected by the radio wave condition. Therefore, for the stored content IDs 006 and 009, the score value (Score [i]) becomes the priority value (Priority) as the content evaluation value as it is.

  FIG. 5 shows an example in which thumbnails of each content are displayed on the drawing / image display unit 201 as a final search result for the user in descending order of priority (Priority value) in the table 400 of FIG. For the thumbnail, the UI control unit 203 acquires thumbnail data corresponding to the content ID to be displayed from the content / metadata management unit 208. In the example of FIG. 5, IDD001 having a priority (Priority value) of 0 and content of ID003 having a value of −1 are also displayed. However, for a content having a priority of 0 or less, a search to be displayed to the user. It is good also as a structure excluded from a result. Alternatively, information indicating that reproduction is not possible in the current radio wave environment may be attached and presented to the user. As an example of the latter, as shown in FIG. 5, the thumbnails of the contents of ID001 and ID003 are drawn and displayed in a light color. As a result, the user can visually and intuitively recognize that “cannot be reproduced now”.

  So far, the user interface design using the deduction functions F (x) and G (y) reflecting the radio wave environment in addition to the score value has been described. In addition to the above, it is desirable to consider the moving speed of the mobile terminal for the content that is streamed. This is because when the mobile terminal is moving, even if the SN ratio is sufficiently secured at the place where the user has searched, it may be moved to a broadcasting or communication out-of-service area while viewing the streaming content. Because.

Therefore, the UI control unit 203 refers to the content / metadata management unit 208, acquires the content length described in the metadata regarding the ST content, and determines the moving speed of the mobile terminal 200 from the moving speed sensing unit 202. Then, the second score deduction value (reflecting the moving speed of the terminal) is further subtracted from the Priority value reflecting the radio wave environment, and Priority ′ is calculated as the final content evaluation value as follows.
・ About communication ST contents
Priority '[ID] = Priority [ID] -P (R, La) (3)
・ About broadcast ST contents
Priority '[ID] = Priority [ID] −P (R, Lb) (4)
here,
La is the length of the communication ST content [minutes],
Lb is the time [minutes] from the current time to the end of the content for the broadcast ST,
R is the moving speed of the mobile terminal [km / h],
P (R, L) is a second adjustment function (score deduction function) with the mobile terminal moving speed R and the content length L as arguments.
It is. In the embodiment, P (R, L) is monotonically increased with respect to the moving speed R of the terminal and monotonically increased with respect to the content length L, but may be monotonically increased with respect to at least one. By using a monotonically increasing function with respect to at least one of the moving speed R and the content length L of the terminal, the mobile terminal 200 was able to view the streaming content at the start of broadcasting or communication while moving. It is possible to avoid a situation in which the radio wave reception intensity becomes low and it becomes impossible to view, and a decrease in usability can be suppressed.

In the embodiment, the following function is determined as the specific function P, but any other appropriate function may be used.
P (L) = Q (L) = R * L / 1000
For example, as a result of referring to the content / metadata management unit 208 by the UI control unit 203, it is assumed that the content length list as shown in FIG. 6 is acquired for the ST content in the list of FIG. Further, it is assumed that R = 30 km / h is acquired by the speed sensor (movement speed sensing unit) 202 provided in the mobile terminal 200. in this case,
P [001] = 30 * 5/1000 = 0.15
P [003] = 30 * 10/1000 = 0.3
P [007] = 30 * 60/1000 = 1.8
Is obtained.

  For FC content (004, 006, 009), the Priority value calculated by Equations (1) and (2) becomes the final content evaluation value Priroity '(Priority' = Priority). As a result, a list 700 including the content evaluation value Priority ′ [ID] is calculated as shown in FIG. A display screen presented to the user by the screen display unit 201 based on the list 700 of FIG. 7 is as shown in FIG.

  In this way, usability is improved by displaying the content that the user can now actually view and play back in an efficient order.

In the first embodiment, the method of displaying the search result list by the search engine 205 in a convenient manner has been described. However, when displaying other content lists, the radio wave environment or the radio wave environment and the moving speed of the terminal are taken into consideration. User interface design techniques can be applied. For example, the present invention can be applied to an application that displays a content list of “recommended content” on the top screen.
FIG. 9 shows an example in which the user interface design method of the present invention is applied to a “recommended content list”. The “recommendation degree” included in the recommended content list 900 is set by the service provider, and the mobile terminal 200 is acquired in advance together with metadata via a broadcast wave or a communication network, and is managed by the content / metadata management unit 208 And The current situation of the mobile terminal 200 is that the communication and broadcast reception strengths are SNa = −80 [dBm], SNb = −20 [dBd], and the moving speed is 30 km / h. At this time, the UI control unit 203 acquires the content length list 1000 of FIG. 10 for each ST content, and generates the list 1100 of FIG. 11 including the storage state information with reference to the content / metadata management unit 208. In the example of FIG. 11, the content IDs 102 and 105 have been saved, and the rest are unsaved.
The UI control unit 203 performs the following calculation for each content using the “recommendation level” given to the content as a score.
・ About communication ST contents
Priority '[ID] = Score [ID]-F (SNa) -P (La) (5)
・ About communication FC contents
Priority '[ID] = Score [ID]-F (SNa) (6)
・ About broadcast ST contents
Priority '[ID] = Score [ID]-G (SNb) -P (Lb) (7)
・ About communication FC contents
Priority '[ID] = Score [ID]-G (SNb) (8)
For ST content, according to equations (5) and (7), the final content evaluation value (Priority ') that takes into account both elements of the radio wave environment (reception strength in communication and broadcasting) and the moving speed of the terminal 200 is obtained. Will be calculated. For FC content, from Equations (6) and (8), a priority value that considers the radio wave environment is used as the final priority value (Priority '= Priority). When calculating for each content based on the above, F (-80) = 1, G (-20) = 3,
Priority '[101] = 3-1-30 * 60/1000 = 2-1.8 = 0.2
Priority '[102] = 5-3 = 2
Priority '[103] = 4-3-30 * 5/1000 = 1-0.15 = 0.85
Priority '[104] = 9-1 = 8
Priority '[105] = 4-3 = 1
Priority '[106] = 3-1 = 2
Priority '[107] = 6-3-30 * 20/1000 = 3-0.6 = 2.4
It becomes. As a result, the table 1200 of FIG. 12 is created, and the content list is displayed in the descending order of the content evaluation value (Priority ').

  FIG. 13 shows a display example of a “recommended content list” corresponding to the list result of FIG. In the displayed list, the content ID 103 is content by broadcasting ST. The streaming content distributed by the broadcast wave is drawn and displayed in the drawing / screen display unit 201 as shown in FIG.

  Streaming content distributed over broadcast waves is different from streaming and saved content on a communication network, and the user cannot view the content from the beginning at any time, and the start and end are controlled at the absolute time. . Therefore, when the content information is presented to the user in the recommended content list or the search result list as in the first embodiment, the content has already started in many cases. Therefore, in the embodiment, the time passage of the broadcast wave streaming content is presented to the user.

  Specifically, the UI control unit 203 refers to the content / metadata management unit 208, refers to the broadcast start and end times described in the metadata accompanying the streaming content, and calculates the content length. . Further, the elapsed time from the start time is calculated based on the time. For example, it is assumed that the broadcast start time of the broadcast ST of the content ID 103 is exactly 10:00, the end time is exactly 11:00, and the current time is 10:20. In this case, the content length is 60 minutes, and the elapsed time from the start is 20 minutes. That is, 20/60 = 1/3, and 1/3 of the entire content length has elapsed. Based on this, content information is displayed as shown in FIG. The content length is written in a rectangular box 1302 at the lower right of the thumbnail 1301, and is drawn lightly as an elapsed length “b” by 1/3 of the horizontal length “a”. As a result, the user can visually and intuitively recognize how long the broadcast has elapsed.

  14A and 14B show a process flow of user interface design (priority display control) performed by the UI control unit 203 of the mobile terminal 200. FIG. First, in S101, the user requests display of a search result or a content list display screen via a user interface such as a numeric keypad attached to the drawing / screen display unit 201. In step S102, the UI control unit 203 that has received the request from the drawing / screen display unit 201 issues a search instruction to the search engine 205 or refers to the content / metadata management unit 208 to acquire a search result or a content list. . The number of contents included in the search result or content list is N, and the score value or recommendation level of the i-th content is Score [i].

  Next, in S103, the UI control unit 203 acquires the reception strength SNa of communication radio waves and the reception strength SNb of broadcast radio waves from the reception strength calculation unit 204, and calculates F (SNa) and G (SNb) for each. . Furthermore, in S104, the moving speed R of the mobile terminal 200 is acquired via the moving speed sensing unit 202. This process leads to S105 in FIG. 14B.

  In S105, the initial value of i is 0 (i = 0). In S106, it is determined whether or not the content i has been stored sequentially for the N pieces of content. If it is already stored, there is no need to consider the radio wave environment, the moving speed of the terminal, etc., so the process proceeds to S115, and the score value of the search or content list is set as the final priority value as it is (Priority '= Score [i ]). If the content [i] to be processed is not stored (NO in S106), it is determined in S107 whether the content is distributed by communication waves or broadcasted by broadcast waves. If it is broadcast content, the process proceeds to S108, and it is determined whether it is streaming distribution (ST) or file casting distribution (FC). In the case of file casting, the process proceeds to S116, where the priority value considering the radio wave environment is set as the final priority value (Priority '= Priority = Score [i] -F (SNb)), and i is incremented. In S119, the priority value is added to the list (for example, the list 900 in FIG. 9), and the process returns to S106.

  On the other hand, if it is determined in S108 that it is broadcast streaming delivery (ST), the process proceeds to S109, where the content length Lb [i] is acquired from the metadata, and the function P (R, Lb [i] of the moving speed and the content length is obtained. ]). Further, the priority value Priority ′ is calculated in S110, i is incremented, and the process returns to S106.

  If the current content is a content to be delivered via communication in S107, the process proceeds to S111 to determine whether it is streaming delivery (ST) or file casting delivery (FC). In the case of file casting, in S113, the priority value considering the radio wave environment is set as the final priority value (Priority '= Priority = Score [i] -F (SNa)), and i is incremented. In S119, the priority value is added to the list, and the process returns to S106.

  If it is determined in S111 that it is communication streaming delivery (ST), the process proceeds to S112, where the content length La [i] is obtained from the metadata, and the function P (R, La [i] of the moving speed and the content length is obtained. ) Is calculated. In S114, the priority value Priority 'is calculated and i is incremented. In S119, the priority value is added to the list, and the process returns to S106.

  The above processing is repeated as long as i <N is satisfied. When the increment value reaches N in S119 (NO in S119), the process proceeds to S120, the list is rearranged according to the priority, and the screen display is instructed to the drawing / screen display unit 201. In this case, the time-lapse display as shown in FIG. 13B is also performed for the broadcast streaming content.

As described above, according to the embodiment, the content can be appropriately presented to the user in accordance with the content storage state and the reception intensity of the communication wave and the broadcast wave, thereby providing the content viewing opportunity with high usability. It becomes possible to do. Further, since the content can be provided according to the moving speed of the mobile terminal according to the content distribution form, the reliability and convenience are further enhanced.
