The detection unit 28 is a sensor that detects various kinds of states of the user U in the real space 100 and surroundings of the providing apparatus 10. The detection unit 28 is a sensor that detects a position of the user U in the real space 100, a posture of the user U, and surroundings of the providing apparatus 10.
The detection unit 28 includes, for example, a position sensor, an acceleration sensor, a gyro sensor, a stereo camera, a Time of Flight (ToF) sensor, or the like. The position sensor detects a position of the user U in the real space. The acceleration sensor detects a motion of the user U in the real space 100.

The detection unit 28 is mounted on a head, a hand, a waist, a leg, or the like of the user U, for example.
The detection unit 28 is not limited to those as described above as long as it is possible to detect the position of the user U and the posture of the user U in the real space 100 and an object that is present around the providing apparatus 10 in the real space 100. For example, the detection unit 28 may detect, by Light Detection And Ranging (LiDAR), an object that is present in the real space 100. For example, the detection unit 28 may detect the position and the posture of the user U by using an image of the real space 100 that is captured by a camera. The detection unit 28 may use, as the position sensor, a beacon, or the like.
The controller 30 controls each of units of the providing apparatus 10. The controller 30 includes, for example, an information processing device such as a CPU or an MPU, and a storage device such as a RAM or a ROM. The controller 30 executes a program that controls operation of the providing apparatus 10 according to the present application. The controller 30 may be implemented by, for example, an integrated circuit such as an Application Specific Integrated Circuit (ASIC) or a Field Programmable Gate Array (FPGA). The controller 30 may be implemented by a combination of hardware and software.
The controller 30 includes a real space information acquisition unit 40, a virtual space information acquisition unit 42, a position information acquisition unit 44, a user behavior determination unit 46, and a virtual space providing unit 48.
The real space information acquisition unit 40 acquires information on a real object that is present in the real space 100. The real object indicates an object that is present in the real space 100. In the example illustrated in
The real space information acquisition unit 40 controls the detection unit 28 and causes the detection unit 28 to detect an object around the providing apparatus 10. The real space information acquisition unit 40 extracts multiple feature points and regions from the detected object by using a well-known technology based on a detection result that is obtained by the detection unit 28. The real space information acquisition unit 40 acquires information on the real object based on the extracted feature points and the extracted regions. A method of acquiring the information on the real object by the real space information acquisition unit 40 is not limited to this example. For example, it may be possible to set, in advance, information on a position or a shape of a furniture in a room of the user U as the information on the real object, and the real space information acquisition unit 40 may acquire the set information on the real object.
A type of the object to be acquired by the real space information acquisition unit 40 may be arbitrary. In the present embodiment, the real space information acquisition unit 40 acquires, as the information on the real object, position information and shape information on an object (for example, the window 110, the desk 120, or the like) that remains still in the real space.
The virtual space information acquisition unit 42 acquires information on a virtual object that is present in the virtual space 200. The virtual object indicates an object that is present in the virtual space 200. In the example illustrated in
The position information acquisition unit 44 acquires user position information. The user position information is information indicating a position of the user avatar AU in the virtual space 200, which is set based on the information on the real object that is acquired by the real space information acquisition unit 40 and the information on the virtual object that is acquired by the virtual space information acquisition unit 42.
In the present embodiment, the position information acquisition unit 44 sets the user position information based on a position relationship between the virtual object and the user avatar AU in the virtual space 200, which is calculated based on the position relationship between the real object and the user U. Specifically, the position information acquisition unit 44 sets the user position information such that a position of the virtual object with respect to the user avatar AU in the virtual space 200 corresponds to a position of the real object with respect to the user U in the real space 100. In other words, the position of the user avatar AU in the virtual space 200, which is indicated by the user position information, is set such that an orientation and a distance from the virtual object to the user avatar AU correspond to an orientation and a distance from the real object to the user U in the real space 100.
The user behavior determination unit 46 determines whether or not the user U has performed a predetermined behavior with respect to the real object in the real space 100. For example, the user behavior determination unit 46 determines an attention level of the user U to the real object. The attention level to the real object is calculated based on a duration in which the real object is looked at or the number of repetitions of looking at the real object at predetermined intervals. The user behavior determination unit 46 calculates a higher attention level as the duration in which the real object is looked at or the number of repetitions of looking at the real object at predetermined intervals increase. The user behavior determination unit 46 determines whether or not the attention level of the user U to the real object exceeds a predetermined threshold. For example, the user behavior determination unit 46 determines whether or not the user U has held his/her hand over the real object. For example, the user behavior determination unit 46 determines whether or not the user U has held his/her hand over the real object in a state in which the user U has approached the real object within a predetermined distance. The predetermined behavior in the real space 100 is not limited to the above examples, and may include a different behavior. The predetermined behavior in the real space 100 may be arbitrarily set in advance by the user U.
The user behavior determination unit 46 determines whether or not the user avatar AU has performed a predetermined behavior with respect to the virtual object in the virtual space 200. For example, the user behavior determination unit 46 determines an attention level of the user avatar AU to the virtual object. The attention level to the virtual object is calculated based on a duration in which the virtual object is looked at or the number of repetitions of looking at the virtual object at predetermined intervals. The user behavior determination unit 46 calculates a higher attention level as the duration in which the virtual object is looked at or the number of repetitions of looking at the virtual object at predetermined intervals increase. The user behavior determination unit 46 determines whether or not the attention level of the user avatar AU to the virtual object exceeds a predetermined threshold. For example, the user behavior determination unit 46 determines whether or not the user avatar AU has held his/her hand over the virtual object. For example, the user behavior determination unit 46 determines whether or not the user avatar AU has held his/her hand over the virtual object in a state in which the user avatar AU has approached the virtual object within a predetermined distance. The predetermined behavior in the virtual space 200 is not limited to the above examples, and may include a different behavior. The predetermined behavior in the virtual space 200 may be arbitrarily set in advance by the user U.
The virtual space providing unit 48 provides the virtual space 200 to the user U based on the user position information. The virtual space providing unit 48 sets a position indicated by the user position information to the position of the user avatar AU in the virtual space 200, and provides the virtual space 200 to the user U. Specifically, the virtual space providing unit 48 acquires information on the position and the orientation of the user U in the real space 100, and converts the position and the orientation of the user U in the real space 100 to a position and an orientation of a viewpoint of the user avatar AU indicated by the user position information in the coordinate system of the virtual space 200. The virtual space providing unit 48 causes the output unit 22 to output, as the image for the virtual space 200, an image of the virtual space 200 in the case where the virtual space 200 is viewed from the calculated position and the calculated posture of the viewpoint of the user avatar AU.
The virtual space providing unit 48 provides the virtual space 200 to the user U based on a determination result of the behavior of the user U obtained by the user behavior determination unit 46. When it is determined that the user U has performed the predetermined behavior, the virtual space providing unit 48 provides the virtual space 200 to the user U. For example, when the user behavior determination unit 46 determines that the attention level of the user U to the desk 120 exceeds a predetermined threshold, the virtual space providing unit 48 provides the virtual space 200 to the user U. For example, when the user behavior determination unit 46 determines that the attention level of the user U to the desk 120 exceeds the predetermined threshold and the user U has held his/her hand over the desk 120, the virtual space providing unit 48 provides the virtual space 200 to the user U.
In the present embodiment, the position and the posture of the user U in the real space 100 are reflected in the position and the posture of the viewpoint of the user avatar AU in the virtual space 200. Therefore, when the user U moves in the real space 100, the position and the posture of the viewpoint of the user avatar AU in the virtual space 200 also move. In this case, it is preferable to associate a movement amount of the user U in the real space 100 with a movement amount of the viewpoint of the user avatar AU in the virtual space 200.
The virtual space providing unit 48 may display an image that represents the real object in the virtual space 200 such that the image is superimposed on the virtual object. The virtual space providing unit 48 may display the image that represents the real object in the virtual space 200 such that the image is superimposed on the virtual object, based on shape information on the virtual object and shape information on the real object. For example, when a size of the virtual object is larger than a size of the real object, the virtual space providing unit 48 may display the image that represents the real object in the virtual space 200 such that the image is superimposed on the virtual object. In this case, the output unit 22 may provide an AR space that displays an image of the virtual space 200 while making the real space 100 transparent or may display the image of the virtual space 200 and the image that represents the real object in a superimposed manner. Furthermore, it may be possible to delete a portion that does not overlap with the real object in the virtual object from the image of the virtual space 200 or provide information as a region that is not associated with the real object.
In the present embodiment, the virtual space providing unit 48 provides a transition space that includes a transition video that indicates a state between the real space 100 and the virtual space 200 to the user U, before providing the virtual space 200. The virtual space providing unit 48 provides the transition space that includes a transition video that indicates a state between the real object in the real space 100 and the virtual object in the virtual space 200 to the user U, before providing the virtual space 200. The transition video is, for example, a video that includes 50% of a video of the real space 100 and 50% of a video of the virtual space 200, but embodiments are not limited to this example. For example, the virtual space providing unit 48 causes the output unit 22 to display, as the transition video, a three-dimensional (3D) desk that has the same size and the same shape as those of the desk 120 while superimposing the 3D desk on the desk 120 by AR. In this case, when the user U opens a drawer of the 3D desk, the virtual space providing unit 48 gradually increases a display region of the virtual space 200 and creates an experience of being drawn into the virtual space 200. At this time, the virtual space providing unit 48 causes the output unit 22 to output not only the video of the virtual space 200, but also sound of the virtual space 200 such that the sound is superimposed on sound of the real space 100. When the user U is transferred to the virtual space 200, the virtual space providing unit 48 causes the output unit 22 to output only the video of the virtual space 200 and the sound of the virtual space 200.
The virtual space providing unit 48 may cause the output unit 22 to display the transition video that corresponds to a type of the real object. For example, when the real object is a manhole, the virtual space providing unit 48 may cause the output unit 22 to display a transition video that creates an experience in which the manhole extends like a flexible tube and a body size of the user U is reduced to allow the user U to enter the tube. For example, when the real object is a window of a building, the virtual space providing unit 48 may cause the output unit 22 to display a transition video that creates an experience in which a ladder or an escalator appears to climb toward the window.
The virtual space providing unit 48 terminates provision of the virtual space 200 and returns the user U to the real space 100 based on a determination result on a behavior of the user avatar AU obtained by the user behavior determination unit 46. When it is determined that the user avatar AU has performed a predetermined behavior, the virtual space providing unit 48 returns the user U to the real space 100. The virtual space providing unit 48 provides the transition video between the virtual space 200 and the real space 100 to the user U, before returning from the virtual space 200 to the real space 100. For example, when the user behavior determination unit 46 determines that an attention level of the user avatar AU to the virtual desk 220 exceeds a predetermined threshold, the virtual space providing unit 48 returns the user U to the real space 100. For example, when the user behavior determination unit 46 determines that the attention level of the user avatar AU to the virtual desk 220 exceeds the predetermined threshold and the user avatar AU has held his/her hand over the virtual desk 220, the virtual space providing unit 48 returns the user U to the real space 100.
The virtual space providing unit 48 may display an exit to return to the real space 100 in the virtual space 200. In this case, for example, when the user behavior determination unit 46 determines that an attention level of the user avatar AU to the exit exceeds a predetermined threshold, the virtual space providing unit 48 returns the user U to the real space 100. For example, when the user behavior determination unit 46 determines that the attention level of the user avatar AU to the exit exceeds the predetermined threshold and the user avatar AU has held his/her hand over the exit, the virtual space providing unit 48 returns the user U to the real space 100.
The virtual space providing unit 48 provides the transition video between the virtual space 200 and the real space 100 to the user U before returning from the virtual space 200 to the real space 100. For example, the virtual space providing unit 48 gradually increases a display region of the exit to the real space 100 and creates an experience of being drawn into the real space 100. At this time, the virtual space providing unit 48 causes the output unit 22 to output not only the video of the real space 100, but also the sound of the real space 100 such that the sound is superimposed on the sound of the virtual space 200.
Details of a process performed by the providing apparatus according to one embodiment will be described below with reference to
The process illustrated in
The real space information acquisition unit 40 acquires information on a real object that is present around the providing apparatus 10 (Step S10). Specifically, the real space information acquisition unit 40 acquires, from the detection unit 28, information on a real object that is present around the providing apparatus 10 and that is detected by the detection unit 28. Then, the process proceeds to Step S12.
The virtual space information acquisition unit 42 acquires information on a virtual object that is present in the virtual space (Step S12). Specifically, the virtual space information acquisition unit 42 acquires the information on the virtual object from the information processing apparatus 12 via the communication unit 26. Then, the process proceeds to Step S14.
The position information acquisition unit 44 acquires user position information that indicates a position of the user in the virtual space (Step S14). Then, the process proceeds to Step S16.
The user behavior determination unit 46 determines whether or not the user U has performed a predetermined behavior in the real space 100 (Step S16). For example, the user behavior determination unit 46 determines that the user has performed the predetermined behavior in the real space when the user has touched a door of a room to enter the room. When it is determined that the user has performed the predetermined behavior in the real space (Step S16; Yes), the process proceeds to Step S18. When it is not determined that the user has performed the predetermined behavior in the real space (Step S16; No), the process at Step S16 is repeated.
When it is determined as Yes at Step S16, the virtual space providing unit 48 provides the transition space to the user U (Step S18). For example, when the user behavior determination unit 46 determines that the user U has touched the door of the room, the virtual space providing unit 48 causes the output unit 22 to output sound of fireworks as if the sound is heard from behind the door. Further, when the user behavior determination unit 46 determines that the user U has entered the room and looked at the window 110, the virtual space providing unit 48 causes the output unit 22 to faintly display a video of the fireworks on the window 110 in a superimposed manner. Then, the process proceeds to Step S20.
The virtual space providing unit 48 provides a virtual space to the user U (Step S20). Specifically, the virtual space providing unit 48 provides a virtual space, in which the position information on the user U in the real space 100 and the position information on the user avatar AU in the virtual space 200 are made consistent, to the user U. For example, the virtual space providing unit 48 causes the output unit 22 to output a video in which a ladder extends from the virtual window 210 that is located at a higher position in the virtual space 200. For example, when the user behavior determination unit 46 determines that the user avatar AU has held his/her hand on the ladder, the virtual space providing unit 48 causes the output unit 22 to output a video in which the user avatar AU climbs up the ladder. At this time, the virtual space providing unit 48 causes the output unit 22 to output louder sound of the fireworks that is heard from outside of the virtual window 210 along with climbing up the ladder. For example, when the user behavior determination unit 46 determines that the user avatar AU has opened the virtual window 210, the virtual space providing unit 48 causes the output unit 22 to output a video in which the fireworks is shot in a clear night view outside the virtual window 210. At this time, the virtual space providing unit 48 causes the output unit 22 to output clear sound of the fireworks. Further, for example, when the user behavior determination unit 46 determines that the user avatar AU is looking around while looking away from the virtual window 210, the virtual space providing unit 48 causes the output unit 22 to output a video in which the room is looked down from a higher position. Then, the process in
Details of a process performed by the providing apparatus according to one embodiment will be described below with reference to
The user behavior determination unit 46 determines whether or not the user avatar AU has performed a predetermined behavior in the virtual space 200 (Step S30). For example, when the user avatar AU closes the virtual window 210 and looks at the ladder, the user behavior determination unit 46 determines that the user avatar AU has performed the predetermined behavior in the virtual space 200. When it is determined that the user avatar AU has performed the predetermined behavior in the virtual space 200 (Step S30; Yes), the process proceeds to Step S32. When it is not determined that the user avatar AU has performed the predetermined behavior in the virtual space 200 (Step S30; No), the process at Step S30 is repeated.
When it is determined as Yes at Step S30, the virtual space providing unit 48 provides the transition space to the user U (Step S32). For example, when the user behavior determination unit 46 determines that the user U has held his/her hand on the ladder, the virtual space providing unit 48 causes the output unit 22 to output a video in which the user U climbs down the ladder. Further, when the user behavior determination unit 46 determines that the user U has looked at the virtual window 210, the virtual space providing unit 48 causes the output unit 22 to faintly display a video of the fireworks on the virtual window 210 with sound that is heard from the virtual window 210. Then, the process proceeds to Step S34.
The virtual space providing unit 48 terminates provision of the virtual space 200 to the user (Step S34). Specifically, the virtual space providing unit 48 terminates output of the video of the fireworks and output of the sound of the fireworks, and causes the output unit 22 to stop display of the virtual space 200. Then, the process in
As described above, in one embodiment, the transition space that indicates a state between the real space and the virtual space is provided to the user before provision of the virtual space. With this configuration, in one embodiment, it is possible to reduce a feeling of discomfort due to a rapid change of a video at the time of switching from the real space to the virtual space when the virtual space is provided. Furthermore, in one embodiment, it is possible to reduce a feeling of auditory discomfort due to a rapid change of sound at the time of switching from the real space to the virtual space when the virtual space is provided.
A configuration example of a providing apparatus according to a modification of one embodiment will be described below with reference to
As illustrated in
The event detection unit 50 detects an event that occurs for the user U in the real space 100. The event detection unit 50 detects an event that occurs for the user U in the real space 100 while the virtual space providing unit 48 is providing the virtual space 200 to the user U. For example, the event detection unit 50 detects, as the event, a possibility that the user U and a real object come into contact with each other in the real space 100.
The event detection unit 50 detects the event based on, for example, a distance between the user U and a real object that is detected by the detection unit 28. For example, when the distance between the user U and the real object is equal to or smaller than a threshold, the event detection unit 50 detects that the event has occurred for the user U. The event detection unit 50 may change the threshold for the distance in accordance with a type of the real object, for example. For example, the event detection unit 50 may increase the threshold for the distance when the real object is a moving body that is approaching the user U as compared to a case where the real object is a stationary body. For example, when the real object is a moving body, the event detection unit 50 may change the threshold for the distance based on speed information on the real object that is detected by the detection unit 28. For example, the event detection unit 50 may increase the threshold for the distance as a moving speed of the real object increases.
When the event is detected, the event detection unit 50 may determine a danger level of the detected event. The danger level indicates an emergency level for giving a notice of the event. For example, the event detection unit 50 determines a higher danger level as the possibility that the user U may get injured when the user U and the detected real object come into contact with each other increases. For example, the event detection unit 50 determines a higher danger level as the possibility that the user U may get seriously injured when the user U and the detected real object come into contact with each other increases. The event detection unit 50 may determine the danger level in a stepwise manner, such as “high”, “medium”, and “low”, for example. The event detection unit 50 may determine the danger level by numerical values, such as “1”, “2”, and “3”, for example.
The event detection unit 50 may determine the danger level in accordance with, for example, a type of the detected real object. For example, the event detection unit 50 may determine a low danger level when the real object is a furniture such as a chair, and determine a high danger level when the real object is a traveling vehicle or the like.
The event detection unit 50 may determine the danger level in accordance with, for example, a size of the detected real object. For example, the event detection unit 50 may determine a lower danger level as the size of the real object decreases, and determine a higher danger level as the size of the real object increases.
The event detection unit 50 may determine the danger level in accordance with, for example, a moving speed of the detected real object. For example, the event detection unit 50 may determine a lower danger level as the moving speed of the real object decreases, and determine a higher danger level as the moving speed of the real object increases.
When the event detection unit 50 detects an event, the notification unit 52 notifies the user U that the event is detected. For example, when the event detection unit 50 detects an event, the notification unit 52 causes the output unit 22 to output notification sound, a notification video, or the like to notify the user U that the event is detected.
The notification unit 52 may change a way of notification in accordance with the danger level of the event that is detected by the event detection unit 50. For example, the notification unit 52 may increase a notification intensity as the danger level increases. For example, the notification unit 52 may cause the output unit 22 to output louder notification sound as the danger level increases. For example, the notification unit 52 may cause the output unit 22 to output a notification video in a more eye-catching manner as the danger level increases.
Details of a process performed by the providing apparatus according to the modification of one embodiment will be described below with reference to
The process illustrated in
The event detection unit 50 determines whether or not an event for the user U is detected in the real space 100 (Step S40). Specifically, when a distance between the user U and the real object detected by the detection unit 28 is equal to or smaller than a predetermined threshold, the event detection unit 50 detects an event for the user U. When the event for the user U is detected (Step S40; Yes), the process proceeds to Step S42. When the event for the user U is not detected (Step S40; No), the process proceeds to Step S46.
When it is determined as Yes at Step S40, the event detection unit 50 determines a danger level of the detected event (Step S42). Specifically, the event detection unit 50 determines the danger level based on a type or a moving speed of the detected real object. Then, the process proceeds to Step S44.
The notification unit 52 gives a notice in accordance with the danger level (Step S44). Specifically, the notification unit 52 causes the output unit 22 to output notification sound or a notification video in accordance with the danger level. Then, the process proceeds to Step S46.
The controller 30A determines whether or not the process is terminated (Step S46). Specifically, when the virtual space providing unit 48 terminates provision of the virtual space 200 to the user U, the controller 30A determines that the process is terminated. When it is determined that the process is terminated (Step S46; Yes), the process in
