[0009] The mobility system described in this specification provides a virtual space image corresponding to a real space image to a user who is riding a mobile vehicle and moving through a predetermined real space (supermarket, shopping mall, gymnasium, etc.). The mobility system allows the user to have a simulated experience of a virtual space (entertainment space) without going to an entertainment facility.

[0010] [1 First Embodiment] [1-1 Configuration of the mobile system 10] FIG. 1 is a schematic configuration diagram of a mobile system 10 according to a first embodiment. The mobile system 10 includes one or more mobile bodies 12 and one or more head-mounted displays 14. A user U wearing a head-mounted display 14 rides on each of the mobile bodies 12. The mobile body 12 on which one user Ua rides is referred to as the own mobile body 12a. The mobile body 12 on which another user Ub rides is referred to as the other mobile body 12b. The mobile bodies 12 and the head-mounted displays 14 are capable of wireless communication with each other.

[0011] FIG. 2 is a functional block diagram of a self moving body 12a according to the first embodiment. The configuration of the other moving body 12b is the same as the configuration of the self moving body 12a. The self moving body 12a is a small electric vehicle (e.g., a cart) that can be boarded by the user Ua. The self moving body 12a moves in a specific real space. The self moving body 12a may be manually driven by the user Ua, or at least some of the driving, braking, and steering may be automatically controllable. In other words, the self moving body 12a may be an autonomous vehicle. Note that in the first embodiment, the self moving body 12a is assumed to be a moving body 12 that travels by being manually driven by the user U. The self moving body 12a includes an imaging unit 18, a driving unit 20, a steering unit 22, a communication unit 24, a calculation unit 26, and a storage unit 28.

[0012] The imaging unit 18 (external sensor) may be configured with a camera. The imaging unit 18 captures an image of the surroundings of the own moving body 12a and acquires an image of real space (referred to as a real space image). The imaging unit 18 outputs the real space image to the calculation unit 26.

[0013] The drive unit 20 may be composed of, for example, a battery, a power supply circuit, an electric motor, a power transmission mechanism, and drive wheels. When the user Ua is manually driving the vehicle, the drive unit 20 applies a driving force and a braking force (regenerative braking) to the vehicle's own moving body 12a in response to pedal operation by the user Ua. When the vehicle is autonomously driven, the drive unit 20 applies a driving force and a braking force to the vehicle's own moving body 12a in response to a determination by the calculation unit 26. The power supply circuit supplies power from the battery to the electric motor during power running, and supplies power from the electric motor to the battery during regeneration. The power transmission mechanism transmits power from the electric motor to the drive wheels during power running, and transmits power from the drive wheels to the electric motor during regeneration.

[0014] The steering unit 22 may be configured with a steering mechanism and a steering wheel. When the user Ua is manually driving the vehicle 12a, the steering unit 22 changes the traveling direction of the vehicle 12a in response to the steering operation of the user Ua. When the vehicle 12a is automatically driven, the steering unit 22 changes the traveling direction of the vehicle 12a in response to the determination of the calculation unit 26.

[0015] The communication unit 24 may be configured, for example, by a wireless communication module including an antenna, etc. The communication unit 24 may transmit signals to the outside of the mobile body 12 a, and may also receive signals from the outside of the mobile body 12 a.

[0016] The calculation unit 26 may be configured by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). That is, the calculation unit 26 may be configured by processing circuitry. At least a part of the calculation unit 26 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). At least a part of the calculation unit 26 may be realized by an electronic circuit including discrete devices.

[0017] The calculation unit 26 includes an acquisition unit 30, a mobile object control unit 32 (control unit), an image recognition unit 34 (recognition unit), an image generation unit 36, a sound generation unit 38, and a communication control unit 40. The acquisition unit 30, the mobile object control unit 32, the image recognition unit 34, the image generation unit 36, the sound generation unit 38, and the communication control unit 40 can be realized by the calculation unit 26 executing a program stored in the storage unit 28.

[0018] The acquisition unit 30 acquires signals transmitted from outside the calculation unit 26. The mobile object control unit 32 controls the behavior of the mobile object 12a. For example, the mobile object control unit 32 controls an electric motor provided in the drive unit 20 in response to pedal operation by the user Ua. The mobile object control unit 32 also controls an electric motor of a steering mechanism provided in the steering unit 22 in response to handle operation by the user Ua. The image recognition unit 34 recognizes real space by performing image recognition on a real space image. The image generation unit 36 ​​generates a virtual space image corresponding to the real space and generates an image signal representing the virtual space image. The sound generation unit 38 generates sound effects (sound) and generates an audio signal representing the sound effect. The communication control unit 40 performs processing to transmit signals to the outside of the mobile object 12a via the communication unit 24.

[0019] The storage unit 28 is a computer-readable storage medium. The storage unit 28 is composed of a volatile memory (not shown) and a non-volatile memory (not shown). The volatile memory is, for example, a random access memory (RAM). The non-volatile memory is, for example, a read-only memory (ROM), a flash memory, etc. Data, etc. are stored in, for example, the volatile memory. Programs, tables, maps, etc. are stored in, for example, the non-volatile memory. At least a part of the storage unit 28 may be provided in the above-mentioned processor, integrated circuit, etc.

[0020] The storage unit 28 stores in advance image data of the virtual space image generated by the image generation unit 36. The image data is used to display an image generated in advance by computer graphics or the like on the head-mounted display 14. The image data may be an entire image of the virtual space image, or a partial image to be superimposed on a part of the real space image. The storage unit 28 stores in advance sound data of sound effects generated by the sound generation unit 38.

[0021] 3 is a functional block diagram of the head mounted display 14 according to the first embodiment. In this specification, the head mounted display 14 is also referred to as an HMD (Head Mounted Display) 14. The HMD 14 is worn on the head of the user Ua. The HMD 14 includes a communication unit 42, a display unit 44, an audio unit 46 (acoustic output unit), a calculation unit 48, and a storage unit 50.

[0022] The communication unit 42 may be configured by, for example, a wireless communication module including an antenna, etc. The communication unit 42 may transmit signals to the outside of the HMD 14. The communication unit 42 may also receive signals from the outside of the HMD 14.

[0023] The display unit 44 may be configured, for example, by a display device. The screen or face of the display device is located close to both eyes of the user Ua. The display unit 44 displays (projects) a virtual space image on a display surface based on an image signal transmitted from the calculation unit 48. The display unit 44 may provide the virtual space image to the user Ua.

[0024] The acoustic unit 46 may be configured, for example, by an audio device. The speakers (including headphones and earphones) of the acoustic unit 46 are placed close to the ears of the user Ua. The acoustic unit 46 outputs sound effects from the speakers based on the acoustic signals transmitted from the calculation unit 48. The acoustic unit 46 may provide the sound effects to the user Ua.

[0025] The calculation unit 48 may be configured by a processor such as a CPU or a GPU. That is, the calculation unit 48 may be configured by a processing circuit. At least a part of the calculation unit 48 may be realized by an integrated circuit such as an ASIC or an FPGA. At least a part of the calculation unit 48 may be realized by an electronic circuit including discrete devices.

[0026] The calculation unit 48 includes an acquisition unit 52, a display control unit 54, and an audio control unit 56. The acquisition unit 52, the display control unit 54, and the audio control unit 56 can be realized by the calculation unit 48 executing a program stored in the storage unit 50.

[0027] The acquisition unit 52 acquires a signal transmitted from outside the calculation unit 48. The display control unit 54 causes the display unit 44 to display a virtual space image. The sound control unit 56 causes the sound unit 46 to output sound effects.

[0028] The storage unit 50 is a computer-readable storage medium. The storage unit 50 is composed of a volatile memory (not shown) and a non-volatile memory (not shown). The volatile memory is, for example, a RAM. The non-volatile memory is, for example, a ROM, a flash memory, etc. Data, etc. are stored in the volatile memory. Programs, tables, maps, etc. are stored in the non-volatile memory, for example. At least a part of the storage unit 50 may be provided in the above-mentioned processor, integrated circuit, etc.

[0029] [1-2 Functions of the Mobile System 10] 4 is a sequence diagram related to the display of virtual space images. In a predetermined real space (supermarket, shopping mall, gymnasium, etc.), user Ua wears HMD 14 and drives own moving body 12a. While moving own moving body 12a, HMD 14 provides user Ua with virtual space images and sound effects according to the situation in the real space. The series of processes shown in FIG. 4 is executed at predetermined time intervals.

[0030] In step S1, the acquisition unit 30 of the own moving body 12a acquires a real space image from the imaging unit 18. The imaging unit 18 of the own moving body 12a captures images of the surroundings of the own moving body 12a all the time or at regular time intervals.

[0031] In step S2, the image recognition unit 34 of the own moving body 12a performs image recognition of the real space image. Furthermore, the image recognition unit 34 determines whether or not a specific space or a specific object (specific object) exists around the own moving body 12a. Information for recognizing the specific space and the specific object is preset in the storage unit 28.

[0032] In step S3, the image generation unit 36 ​​of the own moving body 12a generates a virtual space image corresponding to the real space image. For example, the image generation unit 36 ​​generates the virtual space image by superimposing an image of a predetermined character (e.g., a ghost) on the real space image. The image generation unit 36 ​​may superimpose the image of the predetermined character on a specific space or specific object recognized by the image recognition unit 34, or may superimpose the image of the predetermined character on an arbitrary position on the real space image. The image generation unit 36 ​​may superimpose an image other than a character, such as an image of a desert, on the floor of the real space image. The specific object may be another moving body 12b moving around the own moving body 12a. The specific object may also be determined based on an instruction by the user Ua. For example, if the user Ua's shopping list is stored in the storage unit 28 based on the user Ua's instruction, the specific object may be an item registered on the shopping list. Image data of the predetermined character is stored in the storage unit 28. The image generation unit 36 ​​may generate a virtual space image corresponding to the real space image using images such as computer graphics. Furthermore, the image generation unit 36 ​​may use the image data to generate data for another image. Furthermore, in step S3, the sound generation unit 38 of the own moving body 12a generates a sound effect. The sound effect data is stored in the storage unit 28. Furthermore, the sound generation unit 38 may use the sound effect data to generate data for another sound effect.

[0033] In step S4, the communication control unit 40 of the own moving body 12a generates an image signal corresponding to the virtual space image and an audio signal corresponding to the sound effect, and performs processing to transmit the generated image signal and audio signal. The communication unit 24 of the own moving body 12a transmits the image signal and audio signal to the HMD 14 in accordance with the processing performed by the communication control unit 40.

[0034] In step S5, the communication unit 42 of the HMD 14 receives the image signal and the sound signal. The acquisition unit 52 of the HMD 14 acquires the image signal and the sound signal via the communication unit 42.

[0035] In step S6, the display control unit 54 of the HMD 14 causes the display unit 44 to display a virtual space image in accordance with the image signal acquired by the acquisition unit 52. In addition, the sound control unit 56 of the HMD 14 causes the sound unit 46 to output sound effects in accordance with the sound signal acquired by the acquisition unit 52.

[0036] FIG. 5A is a diagram showing a real space image. FIG. 5B is a diagram showing a virtual space image. According to this embodiment, the imaging unit 18 of the host moving body 12a acquires an image (corresponding to a real space image) 100a as shown in FIG. 5A. The image generation unit 36 ​​of the host moving body 12a generates an image (corresponding to a virtual space image) 100b as shown in FIG. 5B based on the image 100a. The display unit 44 of the HMD 14 displays the image 100b. This allows the user Ua wearing the HMD 14 to experience the sensation of moving through a virtual space where various characters exist.

[0037] [1-3 Variations] When the image generation unit 36 ​​of the calculation unit 26 of the management device 16 generates the entire virtual space image based on image data generated by computer graphics or the like, a real space image does not need to be acquired. In this case, it is necessary to constantly grasp the position and orientation of the own moving body 12a in real space. In this case, the image generation unit 36 ​​can grasp the position and orientation of the own moving body 12a using, for example, existing indoor positioning technology (beacon positioning, inertial navigation, etc.). The storage unit 28 pre-stores image data corresponding to the position and orientation of the own moving body 12a. The image generation unit 36 ​​generates the virtual space image based on image data corresponding to the position and orientation detected by indoor positioning.

[0038] [1-4 Effects of the first embodiment] According to the first embodiment, the user Ua can move through the real space while experiencing the virtual space. Therefore, the user Ua can move through the real space while enjoying it. In other words, according to the present embodiment, it is possible to provide an excellent movement system 10.

[0039] In the first embodiment, the HMD 14 provides the user Ua with a virtual space image including the other moving object 12b, which allows the user Ua to recognize the other moving object 12b.

[0040] In the first embodiment, the HMD 14 provides the user Ua with a virtual space image including an object designated by the user Ua, allowing the user Ua to recognize the designated object. For example, the user Ua can recognize an item registered in the user Ua's shopping list.

[0041] Various functions can be added to the above-described first embodiment and its modifications. Functions that can be added to the first embodiment and its modifications will be described in second to fifth embodiments.

[0042] [2 Second Embodiment] The own moving body 12a may move autonomously in a predetermined situation. For example, the own moving body 12a may move autonomously so as to maintain a certain distance or more from the other moving body 12b. A specific example of this will be described below.

[0043] 6 is a functional block diagram of the mobile object 12a according to the second embodiment. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. The mobile object 12a includes an external environment detection unit 60.

[0044] The external environment detection unit 60 may be configured by one or more external environment sensors including the imaging unit 18. The external environment sensor is, for example, a camera, radar, LiDAR, etc. The external environment detection unit 60 detects the distance between the own moving body 12a and surrounding objects (other moving bodies 12b, etc.). The external environment detection unit 60 outputs the detected information (referred to as distance information) to the calculation unit 26.

[0045] The calculation unit 26 includes a determination unit 62. The determination unit 62 can be realized by the calculation unit 26 executing a program stored in the storage unit 28.

[0046] The determination unit 62 determines whether or not the distance between the other moving body 12b and the own moving body 12a is less than a first distance (predetermined distance) stored in advance in the storage unit 28, based on the distance information.

[0047] When the determination unit 62 determines that the distance between the other moving body 12b and the own moving body 12a is less than the first distance, the moving body control unit 32 autonomously moves the own moving body 12a away from the other moving body 12b.

[0048] The own mobile body 12a can also detect the distance between the other mobile body 12b and the own mobile body 12a through mobile communication performed between the own mobile body 12a and the other mobile body 12b.

[0049] According to the second embodiment, in a real space where a plurality of moving bodies 12 are moving, a user U riding on a moving body 12 can move safely through the real space.

[0050] [3 Third embodiment] As in the second embodiment, the own moving body 12a may move autonomously under predetermined circumstances. For example, the own moving body 12a may automatically follow another moving body 12b in response to approval from the user Ua. The user Ua can approve the following movement of the own moving body 12a by operating a switch or the like (not shown). The configuration of the third embodiment is the same as that of the second embodiment.

[0051] When the own moving body 12a is made to follow the other moving body 12b, the moving body control unit 32 autonomously moves the own moving body 12a so that the distance between the other moving body 12b and the own moving body 12a is maintained at a second distance pre-stored in the storage unit 28. In this case, manual operation of the own moving body 12a by the user Ua is not required.

[0052] According to the third embodiment, the own moving body 12a can move together with the other moving body 12b. For example, the third embodiment is suitable for a case where a plurality of users U move together in a plurality of moving bodies 12.

[0053] [4 Fourth embodiment] The sound generator 38 of the own moving body 12a may change the sound effect depending on the position of the other moving body 12b. For example, the sound generator 38 may generate a sound effect that can be heard from the direction of the other moving body 12b. This allows the user Ua to recognize that the other moving body 12b is present in the direction where the sound effect is generated. In other words, the user Ua can recognize the other moving body 12b with his eyes and ears.

[0054] [5 Fifth embodiment] The mobile system 10 can also make the virtual space an interactive space.

[0055] FIG. 7 is a schematic diagram of a mobile system 10 according to a fifth embodiment. In the fifth embodiment, the same components as those in the first embodiment are assigned the same reference numerals, and their description will be omitted. The mobile system 10 includes a controller 64 (reception unit) that receives instructions from the user Ua. The controller 64 includes an operator that can be operated by the user Ua. The controller 64 wirelessly transmits an instruction signal to the mobile object 12a in response to the operation of the operator by the user Ua.

[0056] The acquisition unit 30 of the own moving object 12a acquires the instruction signal, and the image generation unit 36 ​​of the own moving object 12a generates a virtual space image in response to the instruction signal.

[0057] For example, the image generation unit 36 ​​generates a virtual space image including a game image when a command to display a game image is accepted by the controller 64. The HMD 14 provides the virtual space image including the game image to the user Ua.

[0058] Furthermore, the user Ua can play a game using the controller 64 while viewing a virtual space image including a game image. For example, when a game operation is accepted by the controller 64, the image generation unit 36 ​​generates a virtual space image including an image corresponding to the game operation. The HMD 14 provides the user Ua with the virtual space image including the game image. The game image and software for executing the game are stored in advance in the storage unit 50.

[0059] According to the fifth embodiment, the user Ua can move around while enjoying the real space.
