<About the present invention>
The present invention provides real-time information that is easy to understand by presenting movements of players and movements of balls in various sports broadcasts such as soccer and basketball according to the situation, for example by visually impaired persons. Present in For example, on a regular TV, it is possible to know that the shot was made by the cheering of the audience at the soccer goal shot, but who entered the goal, missed it, who collaborated with who or who the other team I couldn't know immediately whether it was a defense (defense) or not, and I had to know by the announcer's commentary. Therefore, in the present embodiment, the player and the ball are presented as an abstract figure that can be identified by tactile sense on a tactile display on which a plurality of stimulating objects are arranged, and the player's play and ball movement such as a ball pass and goal By presenting in real time as vibration stimulus by changing the vibration of the stimulating object, information presentation that is easy to understand is performed, for example, even for visually impaired people etc. I can enjoy it. In addition, although the stimulation pin mentioned above can use a stimulation pin, an electrode, etc., for example, the following description demonstrates the example using a stimulation pin.

<System configuration>
FIG. 1 is a diagram illustrating a system configuration example of an information presentation system. The information presentation system 10 shown in the example of FIG. 1 shows an example of a system configuration for performing tactile presentation using a tactile display simultaneously with TV broadcast (in real time), but is not limited thereto. For example, when playing back a recorded or downloaded program, the tactile sense presentation control in this embodiment may be performed.

  The information presentation system shown in the example of FIG. 1 includes a broadcasting station 11, a presentation control device 12, a tactile display 13 as an example of a tactile presentation device, a speaker 14 as an example of an audio output device, a display device 15, and the like. Have.

  The broadcast station 11 captures a program to be provided to the user (viewer), transmits the captured content as a TV broadcast wave to the presentation control device 12 by radio waves, and transmits a time table (script information) corresponding to the program to the Internet. And transmitted to the presentation control apparatus 12 via the communication network 16 typified by LAN (Local Area Network).

  Here, the program in the present embodiment is a relay program such as various sports such as soccer and basketball, but is not limited thereto. Also, among sports, for example, soccer or basketball team competition in which a plurality of groups play against each other is preferable.

  In addition, the time table described above includes, for example, person recognition using feature information of a person or face appearing in the program from a TV broadcast wave program image taken, and feature information such as a goal and a ball in the photographed image. Information such as who or what is shown in which time zone and information such as a game situation (for example, a scoring scene) are set for each time by the used object recognition or the like. Further, the time table may be set manually by an administrator, a production person, or the like while watching the program video. Note that the above-described shooting of a program and creation of a time table may be performed by one or a plurality of operators other than the broadcasting station 11.

  The presentation control device 12 has a function as a receiver that receives TV broadcast waves and time tables from the broadcast station 11. In addition, the presentation control device 12 controls presentation information and the like for stimulating the user and recognizing the object by tactile sensation by the tactile display 13 in which a plurality of stimulation objects (stimulation pins) are arranged.

  For example, the presentation control device 12 presents information corresponding to the time table on the tactile display 13 in synchronization with the reproduction time of the TV broadcast wave, or outputs the sound to the speaker 14. The presentation control device 12 may display a broadcast program of TV broadcast waves on the display device 15.

  Here, a functional configuration example of the presentation control device 12 will be specifically described. As a functional configuration of the presentation control device 12, for example, a broadcast wave reception unit 21, a synchronous reproduction unit 22, a time table conversion unit 23, a tactile display drawing unit 24 as an example of a stimulus information generation unit, and an instruction information acquisition unit 25, a speech synthesis unit 26, and a storage unit 27.

  The broadcast wave receiving unit 21 receives TV broadcast waves transmitted from the broadcast station 11 or the like. The broadcast wave receiving unit 21 acquires time synchronization information based on a time stamp from the received TV broadcast wave, and transmits the acquired time synchronization information and broadcast program (video information) to the synchronous reproduction unit 22.

  The synchronized playback unit 22 acquires time table information corresponding to TV broadcast wave program content from the broadcast station 11 via the communication network 16 or the like. In addition, the synchronous reproduction unit 22 acquires time synchronization information and a broadcast program from the broadcast wave reception unit 21. The acquired various information is stored and managed in the storage unit 27 or the like.

  In addition, the synchronization reproduction unit 22 outputs a time table corresponding to the broadcast wave received by the broadcast wave reception unit 21 to the time table conversion unit 23 at a time corresponding to the time synchronization information obtained by the broadcast wave reception unit 21. . The synchronized playback unit 22 outputs the video of the broadcast program to the display device 15 in synchronization with the timing at which the presentation information generated based on the time table is presented on the tactile display 13. That is, the synchronized playback unit 22 causes the tactile display 13 to present the presentation information obtained from the time table information in synchronization with the playback timing of the broadcast program.

  Note that the synchronized playback unit 22 may use a program file downloaded from an external device or the like that can be connected via the communication network 16 such as the Internet, for example, instead of the TV broadcast wave described above.

  The time table conversion unit 23 extracts, from the information included in the time table, position information of each player to be presented using the tactile display 13, information indicating the division of the team, information indicating the position of the ball, and the like. The information is converted into presentation information corresponding to the extracted information by using a conversion table or a predetermined conversion condition stored in advance in the storage unit 27. For example, the time table conversion unit 23 converts position information (coordinate values) on the screen of each player or ball in the time table into position information (coordinate values) of the presentation area of the tactile display 13. Further, the time table conversion unit 23 sets the presentation contents corresponding to the game situation obtained from the parameters in the time table. In this case, a conversion table or the like stored in advance in the storage unit 27 or the like may be referred to, or may be set using an algorithm (program) indicating conversion conditions. The time table conversion unit 23 outputs the converted presentation information to the tactile display drawing unit 24.

  In addition, the time table conversion unit 23 extracts text information for reading a player name or the like from the time table, and outputs the extracted text information to the speech synthesis unit 26.

  Based on the presentation information converted by the time table conversion unit 23, the tactile display drawing unit 24 drives the corresponding stimulation pins among the plurality of stimulation pins arranged at predetermined positions on the tactile display 13 (vibration). Drive control information is generated. That is, the tactile display drawing unit 24 draws various objects on the tactile display based on the drive control information described above. Further, the tactile display drawing unit 24 performs vibration control on various objects presented on the tactile display 13. Here, the object is information that can be acquired from a timetable corresponding to a broadcast program such as a sports broadcast, for example, a player who participated in a competition, a tool used in the competition (for example, a ball, etc.), a field (ground Information (for example, a field outer periphery line), a score, and the like. However, the present invention is not limited to this.

  Further, the tactile display drawing unit 24 redraws the information to be presented on the tactile display 13 in correspondence with the user instruction information (for example, mode change) obtained from the instruction information acquisition unit 25 and outputs the information to the tactile display 13. . The tactile display drawing unit 24 may change the mode in accordance with not only the instruction from the user but also the game situation obtained from the time table, for example.

  In addition, the tactile display drawing unit 24 controls to present the objects separately based on the positional information of the objects so that the object shapes are not deformed by overlapping the presented objects. May be.

  The instruction information acquisition unit 25 acquires information (for example, a selection result) indicated by the user from the tactile display 13. When the instruction information acquisition unit 25 receives a mode change instruction as the instruction content, the instruction information acquisition unit 25 outputs the information to the tactile display drawing unit 24. The mode change means, for example, a change in the presentation contents such as when half of the field is presented or only the players of the team A or only the ball are presented. Further, the mode change may be, for example, a change that is presented at a predetermined time interval or is presented when a player or a ball moves more than a preset threshold. As a result, the user can easily present detailed information such as the passing of the team, the trajectory of the ball, the goal scene, the counter attack, and the set play.

  In addition, when the presentation information (object) of a certain player is instructed (selected) by a user or the like from the tactile display 13, for example, the instruction information acquisition unit 25 is a player name or position corresponding to the instructed object. Can be extracted from information preset in the storage unit 27, and the extracted information can be output to the speech synthesizer 26 and output from the speaker. For example, by pressing the presentation information (stimulus pin) of the player holding the ball, the name of the ball holder (player) can be output as a voice. Also, by pressing the information on the score board presented on the screen, the current score can be output as a voice.

  As described above, the information instructed by the instruction information acquisition unit 25 includes a mode change instruction, a current score, information on a player who has decided a goal, information on an attacking team, etc. It is not limited to this.

  The voice synthesizer 26 generates a voice corresponding to read-out information (text information) such as a player name obtained from the time table conversion unit 23, and outputs the generated voice to the speaker 14. The voice may be a machine voice or may be voice information by a preset person, but is not limited thereto.

  The storage unit 27 stores information for presenting a tactile sensation on the tactile display 13, information corresponding to instruction information from the tactile display 13, and the like. The storage unit 27 is storage means such as a hard disk drive (HDD) or a solid state drive (SSD). The storage unit 27 may be a read only memory (ROM), a random access memory (RAM), or the like.

<Examples of various data>
FIG. 2 is a diagram for explaining various data examples for performing the presentation control process in the present embodiment. FIG. 2A shows an example of shape setting information using a stimulation pin. FIG. 2B shows an example of player information. FIG. 2C shows an example of presentation setting information (conversion table).

  The items of the shape setting information using the stimulation pin shown in FIG. 2A include, for example, “team type” and “shape using the stimulation pin”, but are not limited thereto.

  “Team type” is information for identifying a battle team in a sports broadcast or the like. The “shape using the stimulation pin” is information indicating the shape of an abstract graphic for distinguishing each team. In the example of FIG. 2A, among the same team type (Team A), for example, the stimulus pin shape of the player (A-1) other than the keeper is “◯”, and the stimulus pin shape of the keeper (A-2) Is “□” similar to the shape of “◯”, but is not limited thereto. For example, all players on the same team may have the same shape. In the present embodiment, one or a plurality of shapes can be set even for the same team.

  This shape shows the outer shape of the convex region using a set (bundle) of a plurality of stimulation pins. Therefore, the shape setting information shown in FIG. 2A may be set with the number of stimulation pins necessary for generating the shape.

  Examples of the player information items shown in FIG. 2B include “player type”, “player name”, “position”, and the like, but are not limited thereto. In the example of FIG. 2B, information corresponding to contents (items) included in a time chart described later is set.

  In the example of FIG. 2B, “player type” is information for identifying a player who participates in a competition (such as soccer) in a broadcast program. The player type is information included in the time chart, for example, and text information such as player information (for example, “player name” and “position”) can be acquired using “player type” as a key. The player information is not limited to the example of FIG. 2B, and may be information such as the player's back number, height, weight, age, team, career, and the like.

  In addition, examples of the items of the presentation setting information illustrated in FIG. 2C include “situation information” and “presentation information”, but are not limited thereto. The “situation information” is information for distinguishing the situation of the content to be presented (for example, sports relay). The “presentation information” is information indicating the content of presentation corresponding to the situation information.

  For example, when a ball is received (pass is received) as a situation, processing for reading out the name of the player who has received the ball, and vibrating the stimulation pin for a predetermined time at a predetermined vibration cycle (for example, vibration level 3), etc. However, it is not limited to this. In the present embodiment, information acquired from the time table is converted into information to be presented on the tactile display 13 based on the presentation setting information shown in FIG.

  FIG. 3 is a diagram illustrating an example of a time table. The time table shown in the example of FIG. 3 shows a time chart showing the state of each player, ball, goal, and field appearing corresponding to time (time code). The time table is script information generated from TV broadcast waves in order to obtain presentation information presented on the tactile display 13.

  The items (items) of the time table shown in the example of FIG. 3 include “player type (A1, A2,...)”, “Ball”, “goal”, “field” for each elapse of time (time code). However, the present invention is not limited to this. For example, the player name may be set directly for the player type. In addition, in the time table, position information for each item, presence / absence of a ball for a player, and the like can be specified, but the present invention is not limited to this.

  In the example of the time table of FIG. 3, parameters are set for each item. For example, in the item “player type”, “X, Y” indicates a coordinate value on the screen, and “BFLG” indicates ball holding (1) or no ball (0). “Team: A” indicates that the ball is for team A, and “team: B” indicates that the ball is for team B.

  In the item “ball”, “DFLG: 1” indicates a dribble state (ball holding), and “DFLG: 0” indicates that the ball is alone. In the item “goal”, “GFLG: 1” indicates the goal in, “GFLG: 0” indicates the goal out, “GOAL: A” indicates the goal of the A team, and “GOAL: B” indicates the goal of the B team. Yes.

  In the item “field”, “OFLG: 1” indicates that the ball is out of the field, “OFLG: 0” indicates that the ball is in the field, and “LINE: U” is on the screen. The case where the ball comes out from the line (side line) is shown, and “LINE: D” shows the case where the ball comes out from the line (side line) at the bottom of the screen. Similarly, “LINE: L” indicates the case where the ball comes out from the left line of the screen, “LINE: R” indicates the case where the ball comes out from the right line of the screen, and “LINE: 0” indicates that there is a ball in the field. ing.

  In this embodiment, by referring to the respective parameters in the time chart described above, the position and action of each player (dribbling and passing), the position of the ball, the game situation (shooting, goal, out of field), etc. I can grasp it. Moreover, in this embodiment, the information of a time chart is converted into the presentation information shown on the tactile display 13 using information as shown in the examples of FIG. 2 and FIG. 2 and 3 are obtained from, for example, the broadcasting station 11 and stored in the storage unit 27 and the like.

<Example of presentation control>
Next, an example of presentation control in the present embodiment will be described using a flowchart. FIG. 4 is a flowchart illustrating an example of presentation control. In the example of FIG. 4, the presentation control apparatus 12 acquires a TV broadcast wave from the broadcast station 11 (S01), and acquires a time table corresponding to the acquired TV broadcast (S02). In the process of S01, a TV broadcast wave is used. However, the present invention is not limited to this, and a program file downloaded from an external device or the like that can be connected via the communication network 16 such as the Internet may be used.

  Next, the presentation control apparatus 12 performs reproduction by synchronizing the TV broadcast wave and the time table (S03). That is, control is performed so that the video displayed on the display device 15 and the information presented on the tactile display 13 are synchronized. Next, the presentation control device 12 extracts presentation information presented on the tactile display 13 in association with the time code and voice information output from the speaker 14 from the information in the time table (S04), and the presentation information is preset. Then, conversion is performed using a table, conversion conditions, and the like (S05), and drive control information for driving the corresponding stimulation pins on the screen of the tactile display 13 to be uneven is generated (S06).

  Next, the presentation control apparatus 12 outputs the generated drive control information to the tactile display 13 (S07). Next, the presentation control apparatus 12 outputs audio information to the speaker 14 (S08). In the processes of S07 and S08, audio information corresponding to the content presented by the tactile display 13 is output.

  Here, the presentation control device 12 determines whether or not to end the process (S09), and when all of the timetable information is not reproduced or when other TV broadcast waves or timetables exist (in S09). , NO), the process returns to S04. In addition, when the presentation from the user (forced termination) or the presentation corresponding to the time table is completed (YES in S09), the presentation control device 12 ends the process.

  FIG. 5 is a flowchart illustrating an example of presentation control for instruction information from the tactile display. In the example of FIG. 5, the presentation control device 12 acquires instruction information based on an instruction from the user or the like from the tactile display 13 (S11), refers to the storage unit 27 based on the acquired instruction information, and corresponds to the instruction information. Mode change or voice information is acquired (S12). The audio information includes, for example, the player name and position described above, the current score, etc., but is not limited to this.

  Next, the presentation control device 12 outputs the instructed mode to the tactile display drawing unit 24 (S13), redraws corresponding to the mode (S14), and outputs it to the tactile display 13 (S15). Next, the presentation control apparatus 12 outputs audio information to the speaker 14 (S16). In addition, you may perform the redrawing by the mode change mentioned above not only according to the instruction | indication from a user but according to the condition of the game obtained, for example from a time table.

<Specific examples of content presented on tactile display 13 and control processing>
Next, a specific example of the content presented on the tactile display 13 and a control process will be specifically described.

  In the present embodiment, presentation of sports relay will be described as an example of a program. In the following description, a soccer game relay scene is described as an example. However, the present invention is not limited to this, and can be applied to other sports scenes such as basketball. In the present embodiment, a television relay broadcast (TV broadcast wave) is assumed, but the same applies to a relay via a communication network 16 such as the Internet as well as a broadcast by radio waves.

  FIG. 6 is a diagram illustrating an example in which a soccer broadcast scene is presented. In the example of FIG. 6, the player and ball presentation contents on the tactile display 13 are shown. In the example of FIG. 6, the abstraction of “◯” and “Δ” is based on the shape setting information using the stimulation pin shown in FIG. It is distinguished by a figure. Note that the shape is not limited as long as it can be distinguished by tactile sense, and can be arbitrarily set using the table shown in FIG.

  Here, the content presented on the tactile display 13 as shown in FIG. 6 is expressed by the unevenness of the plurality of arranged stimulation pins. In the example of FIG. 6, a predetermined shape portion such as an abstract graphic or a line indicating a player or a field is presented by the unevenness control of the stimulation pin. In addition, in the example of FIG. 6, by pressing or touching a shape (for example, ○) meaning each player with a finger, information such as the player's name, position, back number, team name, etc. is conveyed by voice. Can do. Thereby, even if it is a visually handicapped person, for example, each player can be known.

  In addition, the goal keeper object 32 of each team is an abstract graphic such as “□” or “◇” so that it can be distinguished from other players of the same team and the goal keeper of the opponent team. In addition, it is preferable to set this shape to a shape similar to the shape of a teammate player so that it can be easily associated with the same team.

  In the example of FIG. 6, a player who keeps the ball (in FIG. 6, the object 31-1) is presented with vibration, and a player who does not keep the ball (object) is non-vibrated. In FIG. 6, for convenience of explanation, an object in a vibration presenting state is indicated by a white shape (for example, “◯”), and an object in a non-vibrating state is indicated by a black shape (for example, “●”). ing. Thereby, a user such as a visually impaired person can easily know the position of the player who is keeping the ball.

  Further, in the present embodiment, by presenting only the players of team A by changing the mode, it is possible to present the scenes that are being passed by the team in an easy-to-understand manner. Also, in order to make it easier to understand the squeeze around the goal, multiple presentations such as presenting the entire field, presenting half of the field, or enlarging only the specified area such as the vicinity of the goal, etc. Set the mode. Thus, by changing the content presented on the tactile display 13 in response to the mode change instruction from the user, the information desired by the user can be presented appropriately.

  Moreover, in this embodiment, you may show in real time like the movement of an actual player and a ball | bowl, corresponding to the timing code | cord | chord (for example, 1 second interval) of a timetable, and the timing to show a player or a ball | bowl. Also, in this embodiment, when a small movement becomes noise and is difficult to understand, a threshold is set for a position change based on the coordinate value of a player or the like, and is presented when there is a large position change greater than or equal to the threshold. By doing so, it is also possible to present the movement more clearly. Processing corresponding to these various change modes is stored in, for example, the storage unit 27 described above, and control information corresponding to the change mode instructed by the user is acquired from the storage unit 27 to change the presentation content. Can do. Further, the mode may be changed according to the game situation obtained from the time table. For example, if it is determined from the timetable that a soccer penalty kick (PK) will be performed, half of the field may be displayed based on the ball position, or the penalty area may be expanded and presented. Also good.

  FIG. 7 is a diagram illustrating a presentation example according to the game situation. For example, when a mode change instruction is received, as shown in FIGS. 7A and 7B, a half field where the ball exists may be presented from the entire field presentation. The position of the ball can be obtained from the XY coordinates of the item “ball” in the time table shown in FIG.

  Further, in the present embodiment, as shown in FIG. 7A, when the object 41-1 of the player who keeps the ball kicks the ball, the line segment 42 is presented in the moving direction of the ball, and the constant Change the time expansion and contraction. Thereby, the user can know from the presentation information that the player has kicked the ball and the moving direction of the ball. While the ball is kept, the object 41-1 vibrates with a preset steady vibration (for example, vibration level 1), but when the ball is released, no vibration (for example, vibration level 0). It becomes. In addition, the object 41-2 that has received the moved ball vibrates vigorously (eg, vibration level 3), for example, “bull bull” only at the moment of reception (predetermined time), and thereafter, the ball is kept. Therefore, it becomes a steady vibration (vibration level 1). Thus, the user can sensuously know the pass exchange between the players from the content presented on the tactile display 13.

  In the present embodiment, as shown in FIG. 7B, when a player (for example, the object 41-3) takes a goal shot and the shot is decided, the goal outer periphery line 43 or the goal (goal mouse) 44 is used. Is vibrated vigorously (eg, vibration level 3), for example, “Bulburu”. Further, when the chute is removed, the line 43 and the goal 44 on the outer periphery of the goal are vibrated with a slightly high-frequency steady vibration (for example, vibration level 2). When the keeper catches the ball, the keeper object 45 is vibrated vigorously (eg, vibration level 3) and presented. Thereby, the user can easily know the result (situation) of the shot.

  Conventionally, a visually handicapped person cannot know that a shot has been decided immediately from an announcer's voice or the like even if he / she knows that the goal has been achieved by the voice of the audience in a soccer broadcast or the like. However, in the present embodiment, the visually impaired person can experience a sense of realism just before the goal at the same timing as the sighted person by the above-described presentation method.

  Furthermore, in this embodiment, even when the ball goes out of the field or when the game is interrupted by a foul or the like, it can be easily communicated by vibrating the line 43 of the field.

  FIG. 8 is a diagram illustrating an example of the ball presentation mode. In the example of FIG. 8, only the ball object 51 is presented without presenting the player. The arrow of FIG. 8 has shown the direction of the object 51 shown with progress of time. In this mode, since the player object is not presented, the movement of the ball can be known more clearly.

  In the example of FIG. 8, in order to distinguish which team has the ball, processing is performed to change the shape (abstract figure) presented when the player of the opponent team (enemy team) keeps the ball. Also good. In the example of FIG. 8, since the opponent team has taken the ball, the shape of the object is changed from “◯” to “Δ” and presented. This makes it easy to know which team the ball is. In addition, by pressing or touching the ball object 51 presented on the tactile display 13, the name of the player who keeps the ball can be output by voice.

  Here, the situation such as the above-mentioned pass to the same team, goal shoot, out-of-field etc. can be easily obtained from the above-mentioned time chart shown in FIG.

<Specific example when objects overlap>
Here, depending on the contents of presentation, a case where a plurality of objects are overlapped due to, for example, competing balls between players is assumed. In such a case, if the position information is presented as it is, it is difficult to determine the shape of the object. Therefore, in this embodiment, the tactile display drawing unit 24 controls and presents predetermined objects such as players' objects so as to be presented apart from each other without overlapping.

  FIG. 9 is a diagram illustrating a specific example of object presentation control. For example, when the player objects 61-1 and 61-2 are approaching each other by competing for the ball, the players (the same applies to the player and the ball) overlap each other. For this reason, the outer periphery of the object shape is deformed as shown in FIG. 9A, and the user cannot grasp what object the object is.

  Therefore, in the present embodiment, as shown in FIG. 9B, the player's object is controlled so that the objects 61-1 and 61-2 do not overlap each other. Specifically, for example, circles circumscribing each of the objects 61-1 and 61-2 with respect to the center of the abstract figure (for example, “◯” and “△”) of the objects 61-1 and 61-2. Both the figures 62-1 and 62-2 are set so that the circles 62-1 and 62-2 do not overlap with each other so that the position shown in FIG. 9A is changed to the position shown in FIG. 9B. A position correction process is performed to widen (separate the distance) in the linear direction between the centers. Note that the distance between the objects is preferably, for example, set to a position where the outer circumferences of the set circles overlap, but are not limited thereto.

<Specific example of presentation control based on program processing>
Here, as described above, the presentation contents of each object may be converted based on the conversion table as shown in FIG. 2C described above, or may be processed based on a program (algorithm). Here, a specific example in the case of performing vibration control which is an example of presentation control based on program processing will be described using a flowchart.

  FIG. 10 is a flowchart showing an example of player vibration control. In the example of FIG. 10, the presentation control device 12 determines whether or not the player to be presented has received the ball (S21). For example, the player presented on the tactile display 13 receives the ball by a pass or the like. (YES in S21), the name of the player who has received the ball is read out (S22), and the object is vibrated at a preset vibration level (eg, level 3) (S23). Further, it is determined whether or not a certain time (for example, about 3 to 5 seconds) has elapsed since the vibration of S23 (S24). If the certain time has not elapsed (NO in S24), the processing of S23 is performed. Return and continue to vibrate until a certain time has passed.

  Further, when a certain time has elapsed (YES in S24), vibration by steady vibration (for example, vibration level 1) is performed (S25). The vibration due to the steady vibration indicates a situation where the player holds the ball. Next, the presentation control device 12 determines whether or not the player has kicked the ball (S26). If the player has not kicked the ball (NO in S26), the process of S25 is continued. In the process of S26, when the ball is kicked (YES in S26), a line segment is presented in the kicked direction, and the line segment is repeatedly expanded and contracted (S27).

  Here, it is determined whether or not a fixed time has passed (S28). If the fixed time has not passed (NO in S28), the process of S27 is continued until the fixed time has passed. In the process of S28, when a certain time has elapsed (YES in S28), the presentation of the line segment is terminated (S29). In the process of S21, when the player has not received the ball (NO in S21), no vibration (vibration level 0) is set (S30). Note that the processing described above can be grasped by referring to the time chart shown in FIG. 3 described above. The above-described vibration level indicates that the greater the numerical value of the level, the more intense the vibration occurs, but the present invention is not limited to this.

  FIG. 11 is a flowchart illustrating an example of goal vibration control. In the example of FIG. 11, the presentation control device 12 determines whether or not the ball has entered a preset area (for example, a penalty area) (S41), and when the ball has entered the area (YES in S41). Then, it is determined whether or not the ball has entered the goal (S42).

  When the ball enters the goal (YES in S42), a preset vibration level (vibration level 3) is performed (S43). If the ball does not enter the goal (NO in S42), steady high frequency vibration (vibration level 2) is performed (S44). In the process of S41, if the ball does not enter the area (NO in S41), no vibration (vibration level 0) is set (S45).

  FIG. 12 is a flowchart showing an example of vibration control of the field outer periphery line. In the example of FIG. 12, the presentation control device 12 determines whether the ball is out of the field or the game is interrupted (S51), and when the above condition is satisfied (YES in S51), The vibration is performed at a preset vibration level (vibration level 1) (S52). If the condition of S51 is not satisfied (NO in S51), no vibration (vibration level 0) is set (S53).

  FIG. 13 is a flowchart showing an example of ball vibration control. The processing in FIG. 13 corresponds to a mode in which only the ball is presented, for example, as shown in FIG. 8 described above.

  In the example of FIG. 13, the presentation control device 12 acquires the position of the ball from the time chart (S61), and determines whether or not it is the ball alone (S62). The case where the ball is alone indicates a situation where the ball is not held by any player. Here, if it is not the ball alone (NO in S62), it is determined whether or not the player has received the ball (S63). If the ball has been received, the received player name is read out (S64). Next, the presentation control device 12 determines whether or not the received player is a player of the opponent team (S65). If the player is a player of the opponent team (YES in S65), the shape of the ball is set in advance. It changes to the shape for the other opponent team (for example, Team B) and presents it (S66).

  Further, in the process of S65, when the player is not a player of the opponent team (NO in S65), or after the process of S66, the vibration at a preset vibration level (vibration level 3) with respect to the presented ball shape. (S67). Next, the presentation control device 12 determines whether or not a certain time has elapsed (S68). If the certain time has not elapsed (NO in S68), the vibration in the process of S67 is continued until the certain time has elapsed. . In addition, the presentation control device 12 changes the vibration of the ball being presented to a steady vibration (vibration level 1) after a predetermined time has elapsed (S69). In the process of S62, if the ball is alone (YES in S62), no vibration (vibration level) is set (S70).

  According to each of the embodiments described above, in a sports scene such as soccer, for example, a player who does not touch the ball vibrates on the tactile display 13 and vibrates for a certain period of time at the received moment. Presented with steady vibration while keeping. Further, in this embodiment, when the player kicks the ball, the line segment indicating the jump destination of the ball repeatedly expands and contracts in the kicked direction, so that the tactile stimulation to the visually impaired person is coordinated and more clearly It is possible to know the moving direction of the ball. Further, in this embodiment, after kicking the ball and presenting the direction of the ball for a certain period of time, the player does not keep the ball and changes to no vibration.

  Further, in the present embodiment, it is possible to control the vibration of the line on the outer periphery of the goal and the penalty area at the time of goal shooting. For example, when a ball enters an area that is regarded as a goal shoot and a goal is further determined, the line around the goal or the entire goal vibrates as “bull bull”. In addition, when the goal shoot is removed, the user can know whether or not the shot has been decided by making a steady vibration at a high frequency that is clearly felt.

  Note that the difference in vibration and the vibration frequency such as the “bull bull” vibration (vibration level 3) and the steady vibration (vibration level 1) described above are examples for more clearly distinguishing the difference in the presentation contents. Vibration mode may be used.

  In addition, in this embodiment, when the ball goes out of the field or when the game is interrupted, the visually impaired person can know that the play is interrupted by constantly vibrating the line on the outer periphery of the field. Also good. Further, as described above, ball vibration control, goal vibration control, and field outer peripheral frame vibration control in a mode in which only the ball is presented may be performed.

  Note that the setting of the vibration level and the object to be vibrated can be arbitrarily set or the mode can be changed according to the user's preference.
