[Figure 4] FIG. 11 is a diagram showing a provision system according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment will be described with reference to the drawings. The following embodiment is merely an example, and various modifications are possible within the scope of the present disclosure.

[0011] Embodiment 1 1 is a diagram showing a provision system according to a first embodiment. The provision system allows a user to have a simulated experience of a disaster. The provision system includes a provision device 100, a visual device 200, and a haptic device 300. The provision system may include servers 400, 410, and 420.

[0012] The providing device 100, the visual device 200, the haptic device 300, and the servers 400, 410, and 420 are connected via a network. The network may be a wired network or a wireless network.

[0013] The providing device 100 is a device that executes the providing method. The visual device 200 and the haptic device 300 are devices worn by a user. For example, the visual device 200 is a goggle-type device. For example, the haptic device 300 is a glove-type device. The server 400 stores a hazard map DB (Database). The server 410 stores a sensory information DB. The server 420 stores an image DB.

[0014] Next, the hardware of the providing device 100 will be described. 2 is a diagram showing hardware included in the providing device of the embodiment 1. The providing device 100 is a computer. The providing device 100 includes a processor 101, a volatile storage device 102, and a non-volatile storage device 103.

[0015] The processor 101 controls the entire providing device 100. For example, the processor 101 is a central processing unit (CPU) or a field programmable gate array (FPGA). The processor 101 may be a multiprocessor. Furthermore, the providing device 100 may include a processing circuit.

[0016] The volatile storage device 102 is a main storage device of the providing device 100. For example, the volatile storage device 102 is a random access memory (RAM). The non-volatile storage device 103 is an auxiliary storage device of the providing device 100. For example, the non-volatile storage device 103 is a hard disk drive (HDD) or a solid state drive (SSD).

[0017] Next, functions of the providing device 100 will be described. 3 is a block diagram showing functions of a providing device according to embodiment 1. The providing device 100 includes a storage unit 110, an acquisition unit 120, a generation unit 130, and a transmission unit 140.

[0018] The storage unit 110 may be realized as a storage area secured in the volatile storage device 102 or the non-volatile storage device 103 . A part or all of the acquiring unit 120, the generating unit 130, and the transmitting unit 140 may be realized by a processing circuit. Also, a part or all of the acquiring unit 120, the generating unit 130, and the transmitting unit 140 may be realized as a module of a program executed by the processor 101. For example, the program executed by the processor 101 is also called a providing program. For example, the providing program is recorded on a recording medium.

[0019] The storage unit 110 stores various information. The storage unit 110 may also store a hazard map DB, a sensory information DB, and an image DB. The sensory information DB may store data related to the user's senses.

[0020] The acquisition unit 120 acquires the simulated experience content information. For example, the acquisition unit 120 acquires the simulated experience content information from the storage unit 110. Also, for example, the acquisition unit 120 acquires the simulated experience content information from an external device. Note that the external device is a device that exists outside the providing device 100. For example, the external device is a cloud server. Note that the illustration of the external device is omitted. Also, for example, the acquisition unit 120 acquires the simulated experience content information by an input operation by the user.

[0021] Here, the simulated experience content information is information indicating the content of the simulated experience desired by the user. For example, the simulated experience content information indicates a simulated experience of a water-related disaster or a fire-related disaster. Specifically, the simulated experience content information indicates the type of disaster, the scale of the disaster, and the location of the disaster. The types of disaster include earthquakes, fires, tsunamis, and river flooding. For example, if the type of disaster is an earthquake, the scale of the disaster is the magnitude. For example, if the type of disaster is a fire, the scale of the disaster is the scale of the fire spread. For example, if the type of disaster is a tsunami, the scale of the disaster is the height of the tsunami and the area of ​​impact of the tsunami.

[0022] The acquisition unit 120 acquires information for generating a scenario for the user to have a simulated experience based on the simulated experience content information. For example, the acquisition unit 120 acquires the information for generating a scenario for the user to have a simulated experience from a hazard map DB based on the simulated experience content information. The generation unit 130 generates a scenario based on the information for generating a scenario. The acquisition unit 120 acquires a video corresponding to the scenario. For example, the acquisition unit 120 acquires a video corresponding to the scenario from a video DB.

[0023] The acquisition unit 120 also acquires tactile information, which is information for giving the user a wet or hot sensation in conjunction with the video, from the sensory information DB. In particular, if the video is of a water-related disaster such as a tsunami or a river flood, the acquisition unit 120 acquires information for giving the user a wet sensation from the sensory information DB. If the video is of a fire-related disaster such as a fire, the acquisition unit 120 acquires information for giving the user a hot sensation from the sensory information DB.

[0024] The transmission unit 140 transmits the video to the visual device 200. The transmission unit 140 also transmits haptic information to the haptic device 300. This allows the user to view the video via the visual device 200 and receive a sensation of being wet with water or feeling heat via the haptic device 300.

[0025] According to the first embodiment, the providing device 100 transmits an image of a water-related disaster or an image of a fire-related disaster to the visual device 200, and transmits haptic information, which is information for giving the user the sensation of being wet with water or feeling heat, to the haptic device 300 in conjunction with the image. This allows the user to have a simulated experience of a water-related disaster or a fire-related disaster. Thus, the providing device 100 can allow the user to have a simulated experience of disasters other than earthquakes.

[0026] Here, the providing device 100 may not generate a scenario. When the simulated experience content information indicates a simulated experience of a disaster related to water, the acquiring unit 120 may acquire a video of the disaster related to water from the storage unit 110 or an external device. When the simulated experience content information indicates a simulated experience of a disaster related to fire, the acquiring unit 120 may acquire a video of the disaster related to fire from the storage unit 110 or an external device. The acquiring unit 120 may acquire haptic information, which is information for giving the user a sensation of being wet with water or a sensation of feeling heat, from the sensory information DB in conjunction with the acquired video. The transmitting unit 140 may transmit the acquired video to the visual device 200. The transmitting unit 140 may transmit the haptic information to the haptic device 300.

[0027] Furthermore, the providing system may include an olfactory device. The providing apparatus 100 is connected to the olfactory device via a network. The acquiring unit 120 may acquire olfactory information, which is information for providing the user with the smell of the disaster site, from the sensory information DB in conjunction with the video. The transmitting unit 140 transmits the olfactory information to the olfactory device. This allows the user to smell the smell of the disaster site. Therefore, the user can experience a more realistic sense of the disaster.

[0028] Embodiment 2 Next, a description will be given of embodiment 2. In embodiment 2, differences from embodiment 1 will be mainly described. In embodiment 2, descriptions of matters common to embodiment 1 will be omitted.

[0029] The acquisition unit 120 acquires a hazard map from a hazard map DB. The generating unit 130 generates an image showing an evacuation route based on the scenario and the hazard map. For example, the generating unit 130 may generate an image showing an evacuation route by using the technology described in Non-Patent Document 1 or Non-Patent Document 2. The transmission unit 140 transmits the image showing the evacuation route to the visual device 200. This allows the user to recognize the evacuation route.

[0030] According to the second embodiment, the providing device 100 can allow the user to experience a simulated disaster other than an earthquake, and can also allow the user to recognize evacuation routes.

[0031] Embodiment 3 Next, a description will be given of embodiment 3. In embodiment 3, differences from embodiment 1 will be mainly described. In embodiment 3, descriptions of matters common to embodiment 1 will be omitted.

[0032] 4 is a diagram showing a provision system according to the third embodiment. The provision system may include a sensor 500 and a camera 600. The sensor 500 and the camera 600 are installed at the disaster site. For example, the sensor 500 is a water level gauge, a thermometer, a hygrometer, or the like.

[0033] The server 400 updates the hazard map DB based on the information measured by the sensor 500. For example, the server 400 updates the hazard map DB using the method described in Non-Patent Document 3. Server 420 accumulates the video generated by camera 600 in the video DB. Server 420 may also update the video stored in the video DB based on the video generated by camera 600. When temperature, humidity, or the like is associated with the video, server 420 may update the temperature, humidity, or the like based on information measured by sensor 500.

[0034] The above describes the case where the servers 400 and 420 operate. When the providing device 100 stores a hazard map DB, the providing device 100 updates the hazard map DB based on information measured by the sensor 500. When the providing device 100 stores an image DB, the providing device 100 accumulates images generated by the camera 600 in the image DB.

[0035] When the simulated experience content information acquired by the acquisition unit 120 is the content of a disaster occurring in real time, the acquisition unit 120 acquires information for generating a scenario for the user to have a simulated experience from the hazard map DB based on the simulated experience content information. The generation unit 130 generates a scenario based on the information for generating the scenario. The acquisition unit 120 acquires an image corresponding to the scenario from the image DB. Then, the transmission unit 140 transmits the image to the visual device 200. This allows the user to experience a disaster occurring in real time.

[0036] According to the third embodiment, the providing device 100 can allow the user to simulate the experience of a disaster occurring in real time.

[0037] Embodiment 4 Next, a fourth embodiment will be described. In the fourth embodiment, differences from the first to third embodiments will be mainly described. In the fourth embodiment, descriptions of the commonalities between the first to third embodiments will be omitted. The fourth embodiment is a combination of the second and third embodiments.

[0038] The acquisition unit 120 acquires a hazard map from a hazard map DB. The hazard map DB is updated based on information measured by the sensor 500. The generation unit 130 generates an image showing an evacuation route based on the scenario and a hazard map. The transmission unit 140 transmits the image showing the evacuation route to the visual device 200. This allows the user to recognize the evacuation route.

[0039] According to the fourth embodiment, the providing device 100 can allow the user to experience a simulated disaster occurring in real time, and can also allow the user to recognize evacuation routes.

[0040] The features of each of the embodiments described above can be combined with each other as appropriate.
