The present disclosure relates to a display control device, a display control method, and a program.
In recent years, athletes (actors) wear devices that can receive various kinds of information from the outside via a communication network or the like and perform exercises.
Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2002-507734 discloses a technology for providing information regarding a traveling distance of an athlete to the athlete or a device used by the athlete during an exercise based on global positioning satellite data.
When one actor acts at a given action position, the actor wants to know the past actions of other actors at the same position in some cases. This is because when the one actor knows the past actions of the other actors at the same position, for example, the one actor can perform an action appropriate for a situation, referring to the past action of the other actors.
However, in Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2002-507734, a technology for informing one athlete of exercise information regarding other athletes is not mentioned.
It is desirable to provide given display realistically using action information a past action of regarding another actor during an action of one actor.
According to an embodiment of the present disclosure, there is provided a display control device including an action information acquisition unit that acquires, at an action position of one actor, action information regarding a past action of another actor, an object generation unit that generates a virtual object for virtually indicating a position of the other actor during an action of the one actor based on the acquired action information, and a display control unit that causes a display unit displaying a surrounding scene to superimpose and display the generated virtual object during the action of the one actor.
According to the above-described configuration, the object generation unit generates the virtual object for virtually indicating the position of the other actor during the action of the one actor based on the acquired action information. Then, the display control unit causes the display unit displaying a surrounding scene to superimpose and display the generated virtual object during the action of the one actor. Thus, when the one actor is acting in a specific place, the display unit displays the virtual object corresponding to the action information regarding the past action of the other actor at the same place. That is, during the action of the one actor, the display is realized realistically using the past action information of the other actor. As a result, the one actor continues the action while viewing the virtual object displayed during the action. Therefore, the one actor can compete with the other actor or can act based on the action of the other actor instead of a guide.
Further, according to an embodiment of the present disclosure, there is provided a display control method including acquiring, at an action position of one actor, action information regarding a past action of another actor, generating a virtual object for virtually indicating a position of the other actor during an action of the one actor based on the acquired action information, and causing a display unit displaying a surrounding scene to superimpose and display the generated virtual object during the action of the one actor.
Further, according to an embodiment of the present disclosure, there is provided a program for causing a computer to execute acquiring, at an action position of one actor, action information regarding a past action of another actor, generating a virtual object for virtually indicating a position of the other actor during an action of the one actor based on the acquired action information, and causing a display unit displaying a surrounding scene to superimpose and display the generated virtual object during the action of the one actor.
According to the embodiments of the present disclosure described above, it is possible to provide realistic display using action information regarding a past action of another actor during an action of one actor.
Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the appended drawings.

The GPS processing unit 128 acquires position information regarding the display device 100 (user) based on a signal received from the GPS satellite 500 (see
The gyro sensor 130 is an angular velocity sensor that detects the angle of the sight line of the user who wears the display device 100. The gyro sensor 130 may be, for example, a triaxial gyro sensor that detects, as a voltage value, a velocity (angular velocity) at which a rotational angle around the X axis, the Y axis, and the Z axis varies. The gyro sensor 130 supplies data of the detected angular velocity to the CPU 112.
The atmosphere pressure sensor 132 is a sensor that detects the altitude of the current position of the user. The atmosphere pressure sensor 132 detects the altitude as a predetermined sampling frequency and supplies the detected data to the CPU 112.
The acceleration sensor 134 is a sensor that detects a movement of the user who wears the display device 100. For example, the acceleration sensor 134 detects whether the user is moving (exercising) or has stopped. The acceleration sensor 134 may be a triaxial acceleration sensor that detects each of an acceleration in the X axis direction, an acceleration in the Y axis direction, and an acceleration in the Z axis direction. The acceleration sensor 134 supplies data of the detected acceleration to the CPU 112.

(2-2. Example of Functional Configuration of Display Device)
An example of a functional configuration of the display device 100 according to the embodiment of the present disclosure will be described with reference to
As shown in
(Position Information Acquisition Unit 202)
The position information acquisition unit 202 acquires position information (in other words, position information regarding the user Ua who wears the display device 100) regarding the display device 100. The position information acquisition unit 202 acquires the position information regarding the display device 100 (the user Ua) through the GPS processing unit 128. For example, the acquired position information is information regarding a latitude, a longitude, and an altitude of the display device 100. The position information acquisition unit 202 acquires the position information at predetermined intervals.
(Action Determination Unit 204)
The action determination unit 204 determines an action of the user Ua who wears the display device 100. For example, the action determination unit 204 determines whether the user Ua is exercising. Specifically, the action determination unit 204 determines whether the user Ua is exercising based on a detection result of the acceleration sensor 134.
The action determination unit 204 may determine whether the user Ua starts a running action based on a detection result of the acceleration sensor 134. Further, the action determination unit 204 may determine an action of the user based on the position information acquired by the position information acquisition unit 202.
(Action Information Acquisition Unit 206)
The action information acquisition unit 206 acquires action information regarding a past action of the user Ub or Uc (another action) at the action position of the user Ua (one actor) who wears the display device 100 from the server 300 (see
For example, the action information acquisition unit 206 acquires an exercise history of the user Ub or the user Uc as action information. Here, the acquired exercise history is a running history of the user Ub or Uc who has run at the position at which the user Ua is running. The exercise history to be acquired may be determined when the user Ua starts exercising and the user Ua selects the exercise history on a menu screen displayed on the display unit 118. Further, the exercise history to be acquired may be set in advance, for example, at the user's home before exercise.
The action information acquisition unit 206 acquires not only the action information but also map information including information regarding the altitude of the position at which another user Ub or Uc acts from the server 300. By acquiring the map information including the information regarding the altitude, the position of another user can be detected with higher accuracy.
Here, action information to be downloaded from the server 300 will be described with reference to
(Captured Image Acquisition Unit 208)
The captured image acquisition unit 208 acquires a captured image captured by the imaging unit 136. For example, the captured image acquisition unit 208 acquires the captured image (visual field image) obtained by imaging a visual field of the user by the imaging unit 136. The captured image acquisition unit 208 outputs the acquired captured image to the image processing unit 210.
(Visual Field Information Acquisition Unit 210)
The visual field information acquisition unit 210 acquires visual field information of the user Ua who wears the display device 100. The visual field information acquisition unit 210 acquires, as visual field information, for example, information regarding the direction (azimuth) of the sight line of the user Ua or the angle of the sight line of the user Ua. The direction (azimuth) of the sight line of the user Ua is detected by the electronic compass 126 which is an example of the sight line detecting unit. The angle of the sight line of the user Ua is detected by the gyro sensor 130.
(Image Processing Unit 212)
The image processing unit 212 performs various kinds of image processing on the captured image acquired by the captured image acquisition unit 208. The image processing unit 212 has a function of a determination identifying unit that identifies the range of a road on which the user is running from the captured image obtained by imaging the visual field of the user Ua by the imaging unit 136.
Hereinafter, a method of identifying the range of a road from the acquired captured image will be described with reference to
As shown in
(Position Determination Unit 214)
The position determination unit 214 determines whether another user Ub (or Uc) was located in the past at the position within the visual field of the user Ua during the action. Specifically, the position determination unit 214 determines whether the other user was located in the past within the visual field of the user based on the range of the road identified by the image processing unit 212 and the position of the other user Ub.
For example, the position determination unit 214 determines that the other user Ub is located at the position within the visual field of the one user Ua, when the other user Ub is located within the range of the road identified by the image processing unit 212. Conversely, the position determination unit 214 determines that the other user Ub is not located at the position within the visual field of the one user Ua, when the other user Ub is not located within the identified range of the road.
(Image Generation Unit 216)
The image generation unit 216 generates a virtual image transparently displayed on the display unit 118. The image generation unit 216 generates, as the virtual image, a virtual object for virtually indicating the position of the other user Ub (or the user Uc) during an action of the user Ua based on the action information acquired by the action information acquisition unit 206. Specifically, when the user Ua is running at a given position, the image generation unit 216 generates the virtual object for virtually indicating the position of the other user Ub (or the user Uc) that has run in practice at the same position in the past. Further, when a plurality of different users who have run at the same position are present, the image generation unit 216 generates the virtual object corresponding to another user selected by the user Ua.
The image generation unit 216 generates the virtual object suitable for a positional relation between the one user Ua and the other user Ub (or the user Uc). For example, when the other user Ub is running in the front of the user Ua, the image generation unit 216 generates the virtual object showing the back shape of the other user Ub. On the other hand, when the other user Ub is running in the rear of the user Ua, the image generation unit 216 generates the virtual object showing the front shape of the other user Ub.
The image generation unit 216 generates a map indicating the positions of the one user Ua and the other user Ub (or the user Uc). The image generation unit 216 causes the road to be included in the map and shows the positions of the one user Ua and the other user Ub on the road. The map is generated such that the map occupies a partial area in the corner of the display screen of the display unit 118.
(Display Control Unit 218)
The display control unit 218 causes the display unit 118 displaying the surroundings to display the virtual object generated by the image generation unit 216 in a superimposition manner.
Specifically, the display control unit 218 causes the display unit 118 to display the virtual object generated by the image generation unit 216 in the superimposition manner during the action of the user Ua who wears the display device 100. That is, when the user Ua is acting at a specific place, the display control unit 218 causes the display unit 118 to display the virtual object corresponding to the action history of the other user Ub who has acted at the same position in the past. Thus, during the action of the user Ua, given display is realized realistically using actual past action information regarding the user Ub.
The display control unit 218 causes the display unit 118 to transparently display the generated virtual object. For example, the display control unit 218 displays the virtual object in gray or only with a contour line. Thus, it is possible to prevent the visual field of the user Ua from being blocked due to the displayed virtual object.
The display control unit 218 switches the display of the virtual object depending on whether the other user Ub is located within the visual field of the one user Ua. That is, the display control unit 218 causes the display unit 118 to display the virtual object when the position determination unit 214 determines that the other user Ub is located at the position within the visual field of the user Ua. Conversely, the display control unit 218 causes the display unit 118 not to display the virtual object when the position determination unit 214 determines that the other user Ub is not located at the position within the visual field of the user Ua. Thus, the given display can be realized more realistically.
The display control unit 218 switches the display of the virtual object on the display unit 118 in accordance with the positional relation between the other user Ub and the one user Ua and the direction of the sight line of the user Ua. For example, the display control unit 218 causes the display unit 118 to display the virtual object corresponding to the other user Ub when the other user Ub is acting in the front of a traveling direction of the user Ua and it is thus detected that the sight line of the user Ua is oriented toward the front of the traveling direction. Conversely, the display control unit 218 causes the display unit 118 to display the virtual object corresponding to the other user Ub, when the other user Ub is acting in the rear of the traveling direction of the user Ua and it is thus detected that the sight line of the user Ua is oriented toward the rear of the traveling direction (that is, the user Ua is looking back). Thus, the position of the user Ub can be appropriately displayed in accordance with the sight line by switching the display of the virtual object on the display unit 118 in accordance with the direction of the sight line of the user Ua.
The display control unit 218 may cause the display unit 118 to display the virtual object when it is determined that the user Ua who wears the display device 100 starts acting. Thus, when the user Ua does not act, it is possible to prevent the virtual object from being displayed on the display unit 118.
The display control unit 218 may cause the display unit 118 not to display the virtual object when a shielding object is present between the user Ua and the other user Ub in a view from the user Ua. Then, the display control unit 218 causes the display unit 118 to display the virtual object when the user Ua passes the shielding object. Thus, in a situation in which the other user Ub would not normally be viewed due to the shielding object, it is possible to prevent the virtual object corresponding to the other user Ub from being displayed.
The display control unit 218 may change the size of the virtual object to be displayed in accordance with the distance between the other user Ub and the user Ua. For example, the display control unit 218 causes the virtual object to be displayed larger as the other user Ub is located closer to the vicinity of the user Ua.
The display control unit 218 may cause the display unit 118 to display the map showing the positions of the user Ua and the other user Ub in the superimposition manner when it is determined that the other user Ub is not located at the position within the visual field of the user Ua. Thus, by displaying the map showing the positions of the user Ua and the other user Ub, the user Ua can easily comprehend the relative position even when the user Ua is distant from the other user Ub.
Specifically, the display control unit 218 causes the display unit 118 to display the map showing the positions of the user Ua and the other user Ub when it is determined that the other user Ub is not located at the position within the visual field of the user Ua and the other user Ub is distant from the user Ua by a predetermined distance or greater. At this time, in order to prevent the visual field from being blocked by the shown map, the display control unit 218 causes the map to be transparent.
The display control unit 218 may change a scale (magnification) of the map in accordance with the distance between the other user Ub and the user Ua and display the changed map. That is, when the distance between the other user Ub and the user Ua is large, the display control unit 218 enlarges the scale of the map. When the distance between the other user Ub and the user Ua is small, the display control unit 218 reduces the scale of the map. Thus, the display unit 118 can display the positions of the other user Ub and the user Ua within the restricted display area.
(Action Information Transmission Unit 220)
The action information transmission unit 220 transmits (uploads) the action information (for example, exercise information) regarding the user Ua who wears the display device 100 to the server 300. The action information regarding the user Ua is sequentially stored in, for example, the memory 114, and thus the action information transmission unit 220 transmits the series of action information to the server 300 when the exercise is completed. Specifically, the action information transmission unit 220 transmits the exercise information shown in

In the above-described display examples, the display of the virtual object superimposed on a scene is switched when the sight line of the user is moving. Thus, the user can perceive the relative position of the competitor more realistically.
(Display Example in Which Competitor Is Outside of Visual Field)
In the above-described display examples of
The display unit 118 according to the embodiment displays a map showing the positions of the competitor and the user, instead of a virtual object, when the competitor is outside of the visual field of the user. Thus, the user can easily comprehend the position relation between the competitor and the user, while viewing the map showing the positions of the competitor and the user. Hereinafter, a display example of the map when the competitor is outside of the visual field of the user will be described with reference to
Here, the displayed map can be displayed while changing the scale (magnification) of the map in accordance with the positions of the user and the competitor to display the positions of both the user and the competitor, as shown in
In the above-described display examples of
<4. Flow of Process Performed by Display Device>
An example of the flow of a process performed by the display device 100 according to the embodiment will be described with reference to
The position information acquisition unit 202 of the display device 100 acquires position information (position information regarding the user who wears the display device 100) regarding the display device 100 (step S102). That is, the position information acquisition unit 202 acquires information regarding the latitude, longitude, and altitude of the display device 100 (user) through the GPS processing unit 128.
Next, the display device 100 is connected to a social network by the radio communication unit 124 (step S104). Next, the display device 100 receives a competition mode input by the user Ua (step S106). At this time, the user Ua can select a competitor through the input unit 122.
Next, the action information acquisition unit 206 downloads exercise information regarding another user (competitor) from the server 300 (step S108). Then, the action determination unit 204 determines whether the user Ua who wears the display device 100 starts exercising based on a detection result of the acceleration sensor 134 (step S110).
When the action determination unit 204 determines that the user starts exercising in step S110 (Yes), the display device 100 records the exercise information regarding the user Ua in the memory 114 (step S112). Next, the display device 100 determines whether the competitor is exercising (step S114).
When display device 100 determines that the competitor is exercising in step S114 (Yes), the display control unit 218 performs a virtual object display process of displaying a virtual object on the display unit 118 (step S116). Conversely, when the display device 100 determines that the competitor is not exercising in step S114 (No), the display control unit 218 does not perform the virtual object display process of step S116. The details of the virtual object display process of step S116 will be described below.
Next, the action determination unit 204 determines whether the user ends the exercise (step S118). When the action determination unit 204 determines that the user continues the exercise in step S118 (No), the display device 100 performs the above-described process of step S112. Conversely, when the action determination unit 204 determines that the user ends the exercise in step S118 (Yes), the display device 100 uploads the exercise data of the user to the server (step S120).
(Virtual Object Display Process)
An example of the flow of the virtual object display process of step S116 in
The position determination unit 214 of the display device 100 acquires the relative coordinates of the competitor based on the latitudes, longitudes, and altitudes of the user and the competitor (step S202). Next, the image processing unit 212 determines the range of a road in which the user Ua is running from a captured image captured by the imaging unit 136 (step S204).
Next, when the image processing unit 212 can identify the range of the road from the determination result (Yes in step S206), the image processing unit 212 determines whether road information is included in the downloaded map information (step S208).
When the image processing unit 212 determines that the road information is included in step S208 (Yes), the image processing unit 212 performs matching between the identified range of the road and the road information to define the range of the road (step S210).
Next, the position determination unit 214 compares the position of the competitor with the range of the road (step S212). Then, the position determination unit 214 determines whether the competitor is within the visual field of the user (step S214). That is, the position determination unit 214 determines whether the competitor is located within the range of the road.
When the position determination unit 214 determines that the competitor is within the visual field of the user in step S214 (Yes), the image generation unit 216 generates a virtual object based on the coordinates of the competitor and the traveling direction of the competitor (step S216). Then, the display control unit 218 causes the display unit 118 to display the generated virtual object (step S218).
When the position determination unit 214 determines that the competitor is outside of the visual field of the user in step S214 (No), the display control unit 218 causes the display unit 118 not to display the virtual object. Further, when the competitor is distant from the user by a predetermined distance or greater, the display control unit 218 causes the display unit 118 to display the map showing the positions of the competitor and the user.
<5. Case in which Virtual Object is Displayed>
The case in which the display unit 118 displays the virtual object corresponding to the competitor based on the exercise history of another user (competitor) who has run at the specific position in the past when the user Ua who wears the display device 100 is running in a specific position has been described. However, the case in which the display unit 118 displays the virtual object is not limited to the above-described case.
For example, the display unit 118 may display the virtual object based on the exercise history of the other user (competitor) when the user Ua is performing an action (exercise) other than running. Here, examples of the action other than running include bicycling, swimming, automobile driving, motorcycling, sailing, flying, and paragliding.
In a specific facility, a virtual object may be displayed as a guide function. For example, when an area is divided minutely and a user is located in a specific area in a gallery, a zoo, a park, an amusement facility, or the like, a virtual object such as a video may be automatically displayed. Further, a past movement of another person playing a guiding role may be displayed as a virtual object based on movement information. Likewise, a virtual object may be displayed and used as a guide in a route or the like that is difficult to search for.
Further, a virtual object may be displayed based on exercise information performed in the past event. Specifically, in one place, an atmosphere of the past event can be reproduced by displaying the virtual object based on the exercise information or the like of participants of the event performed at the same place in the past.
<6. Summarization>
As described above, the display device 100 according to the embodiment of the present disclosure generates a virtual object for virtually indicating the position of another actor (competitor) during an action of one actor (user) based on acquired action information. Then, the display device 100 can superimpose the generated virtual object on the display unit 118 displaying the surrounding scene during the action of the one actor.
Thus, when the user is exercising in a specific place, the display unit 118 displays the virtual object corresponding to the exercise history of a competitor who has exercised at the same place in the past. That is, during the action of the user, the display is realized realistically using the actual past action information of the competitor. As a result, since the user continues the action while viewing the virtual object displayed during the action, the user can compete with another actor or perform an action using the action of the other actor instead of a guide.
It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
The glasses-type display device 100 (see
The display device 100 has been described as a display control device that generates a virtual object and causes the display unit 118 to display the virtual object, but the embodiment of the present disclosure is not limited thereto. For example, the server 300 may be configured as a display control device that generates a virtual object and causes a display device to display the virtual object. Even in this case, when a user is exercising in a specific place, the display unit 118 displays the virtual object corresponding to exercise history of a competitor who has exercised at the same place in the past. When the server 300 serves as the display control device, the configuration of the display device 100 can be simplified.
While the steps described in the flowcharts according to the above-described embodiment naturally include processes performed chronologically in the described order, but the processes are not necessarily processed chronologically, and the steps may also include processes performed in parallel or separately. Further, the order of the chronologically processed steps may, of course, be changed appropriately, as necessary.
The process performed by an information processing device described in the specification may be realized by any one of software, hardware, and a combination of the hardware and software. For example, a program for the software is stored in a memory medium installed inside or outside each device in advance.
