  In this way, the phobia treatment system presents a subway use scene as a horror scene through the visual, auditory, and tactile sensations of the patient P, and feels as if the patient P is facing an actual subway use scene. Has been made to give.

  In fact, in the case of this embodiment, the phobia treatment system 1 is for the subway phobia patient P who feels fear when using the subway, as shown in FIG. It is the final stop station starting from 1 and passing through Sakura 1-chome Station, Sakura 2-chome Station, No. 30 Building-mae Station, Minami-dori Station, Minami-dori 3rd Avenue Station, Midori intersection Station and Hall No. 50 Mae Station. It is possible to present a three-dimensional virtual space of the route reaching the central street station.

  In this case, first, in the phobia treatment system 1, the patient is seated on the body sonic device 4 with the three-dimensional virtual space viewing means 2 attached to the head of the patient P, and the SSR measuring device 7 is placed on the arm of the patient P. At the same time, the patient controller 3 is held in the hand of the patient P.

  Incidentally, SSR (sympathetic skin reaction) is a biological signal that appears in the skin potential that changes due to mental sweating, and has been reported as a reaction of the sympathetic nervous system related to judgment, attention, and emotion. It has the advantage that no special training is required, and can accurately capture the physical changes of the patient P.

In this state, when the CPU 45 is given an instruction to start the subway phobia treatment by operating the operation section 49 for the therapist H, the CPU 45 is standing at the entrance of the Nishidori Station, which is the first station. A video signal that becomes a three-dimensional virtual space video is sent to the HMD 11 and the display unit 6.
As a result, the HMD 11 and the display unit 6 display a video screen 100 when standing at the doorway of Nishidori Station, which is the starting station, as shown in FIG.

  Here, on the video screen 100, a three-dimensional virtual space video in which people are sparsely arranged with live-action still images is set as an initial setting, and such a congestion setting makes it as if the patient P is real. It is designed to give you the feeling of standing at the entrance of a subway station.

  In addition to such a configuration, the CPU 45 can perform congestion setting by adjusting the number of persons displayed on the video screen 100 by operating the operation section 49 for therapist H, and is optimal for each patient P. It is designed to create a horror scene.

  In the case of this embodiment, the video screen shows the degree of congestion of the therapist H according to the state of the patient P, the unattended state, the degree of sparseness of the person (FIG. 6 (A)), the medium degree of congestion, It can be changed to 4 levels of heavy congestion. Incidentally, FIG. 6 (B) shows the video screen 101 at the entrance / exit of Nishidori Station when the unmanned state is set.

  In the phobia treatment system 1, the patient P himself / herself operates the patient controller 3 to enter the station from the subway entrance / exit of the first departure station (the entrance / exit of Nishidori Station) and move into the station platform through the station. The three-dimensional virtual space image, the three-dimensional virtual space sound, and the bodily sensation are given to the patient P via the HMD 11, the headphones 12, and the body sonic device 4, respectively.

  FIG. 7A is a video screen 102 showing a three-dimensional virtual space image in a station premises where people are sparse as congestion settings, and FIG. 7B is moderately crowded as congestion settings. This is a video screen 103 showing a three-dimensional virtual space image inside a station premises, and the patient controller 3 can move to the three-dimensional virtual space of the station platform by moving in the three-dimensional virtual space as it is in the straight line direction.

  In this embodiment, the patient P can change the moving speed of moving in the three-dimensional virtual space through the patient controller 3 in, for example, four stages, and the patient P can directly control the moving speed. By doing so, it is possible to adjust the burden received in the horror scene by itself.

  Incidentally, in this case, the three-dimensional virtual space image changes so that the first movement speed is slightly slower than the general female walking speed in the three-dimensional virtual space, and the second movement speed is within the three-dimensional virtual space. The three-dimensional virtual space image changes so as to be a general female walking speed in FIG. 2, and the third movement speed is a little faster than the female walking speed in the three-dimensional virtual space as the third movement speed. The three-dimensional virtual space image is set to change so that the fourth moving speed becomes the speed when lightly running in the three-dimensional virtual space.

  In the phobia treatment system 1, a series of events until the train arrives at the subway entrance / exit of the terminal station through various event settings such as waiting for the arrival of the train at the station platform, getting on the train by the patient P, and changing trains. The three-dimensional virtual space image, the three-dimensional virtual space sound, and the bodily sensation stimulus can be presented via the HMD 11, the headphones 12, and the body sonic device 4.

  Further, in this phobia treatment system 1, an event setting for suddenly stopping the train while getting on the train is generated by the therapist H according to the operation of the operation section 49 for the therapist, and the most suitable fear at the optimal timing. The scene can be presented for each patient P.

(2) Station home standby process In practice, the CPU 45 of the personal computer 5 moves the station P from the 3D virtual space image in the station premises to the 3D virtual space image of the station home via the patient controller 3. According to the home standby processing program, as shown in FIG. 8, the routine RT1 is entered from the start step, and the process proceeds to step SP1.

  In step SP1, the CPU 45 sends a station home standby video signal to the HMD 11 to display the station home three-dimensional virtual space video on the HMD 11 and sends a station home standby audio signal to the headphones 12. 3D by outputting 3D virtual space acoustics such as noise corresponding to the 3D virtual space image and announcement of arrival on the premises from the headphone 12, and further sending a stimulus control signal for waiting for the station home to the body sonic device 4. A bodily sensation stimulus corresponding to the virtual space image and the three-dimensional virtual sound is given to the patient P through the body sonic device 4, and the process proceeds to the next step SP2.

  In step SP2, the CPU 45 determines whether or not a station home train arrival instruction is given by the therapist H via the therapist operation unit 49 as a change in the event setting.

  If a negative result is obtained in step SP2, this means that the station home train arrival command has not been given via the therapist operation unit 49, that is, the therapist H has three-dimensional virtual without changing the event setting. This indicates that the patient P is forced to experience the state waiting for the arrival of the train at the station platform in the space. At this time, the CPU 45 returns to step SP1 again.

  On the other hand, if an affirmative result is obtained in step SP2, this means that a station home train arrival instruction has been given via the operation section 49 for the therapist, that is, the therapist H has three-dimensionally changed the event setting. This indicates that the patient P is trying to experience the state when the train arrives in the virtual space. At this time, the CPU 45 proceeds to the next step SP3.

  In step SP3, the CPU 45 sends a video signal for arrival at the train to the HMD 11 to display on the HMD 11 a three-dimensional virtual space image when the train arrives at the station platform, and transmits an acoustic signal for arrival at the train to the headphones. 12 sends out the 3D virtual space sound consisting of the train running sound and brake sound corresponding to the 3D virtual space image from the headphones 12, and the body sonic device also provides a stimulus control signal for arrival at the train. 4 is given to the patient P through the body sonic device 4 and the body sensation stimulus such as vibration upon arrival at the train corresponding to the three-dimensional virtual space image and the three-dimensional virtual sound is transferred to the next step SP4.

  For example, when the patient P is located at the end of the station platform in the three-dimensional virtual space and the train that has traveled from a distance enters the station platform while gradually decreasing the speed, as shown in FIG. A video screen 104 of a three-dimensional virtual space video is displayed on the HMD 11.

  Further, when the patient P is located in the middle of the station platform in the three-dimensional virtual space, when the train door stopped at the station platform opens and the train can be boarded, FIG. A video screen 105 as shown is displayed on the HMD 11. In this way, a series of three-dimensional virtual space images in which a train arrives as shown in FIGS. 9 and 10 is displayed on the HMD 11.

  In step SP4, the CPU 45 determines whether or not the patient P gets on the train from the door of the train that arrives at the station platform in the three-dimensional virtual space based on the coordinates obtained based on the operation command from the patient controller 3. Judging.

  If a negative result is obtained in step SP4, this means that the coordinates obtained by the operation command from the patient controller 3 do not coincide with the coordinates in the train, that is, the patient P is directly in the 3D virtual space image. This means that the user stays at the station platform. At this time, the CPU 45 proceeds to the next step SP5.

  In step SP5, the CPU 45 determines whether or not a door closing command is given from the therapist operation unit 49 as a change in the event setting.

  If a negative result is obtained in step SP5, this means that the door closing command has not been given from the operator section 49, that is, the therapist H has opened the train door without changing the event setting. This represents that the three-dimensional virtual space image in the state is displayed on the HMD 11, and at this time, the CPU 45 returns to step SP4 again.

  At this time, the therapist H displays a 3D virtual space image in which the door of the train arriving at the station platform has been opened for a predetermined time or more on the HMD 11 and displays the 3D virtual space image on the HMD 11 by, for example, a vehicle failure. It is possible to change the event setting to stop operation due to an emergency situation by outputting from the headphone 12 as a three-dimensional virtual space sound an announcement of the fact that there is an emergency stop due to a sudden illness.

  On the other hand, if an affirmative result is obtained in step SP5, this means that the door closing command is given from the operation part 49 for the therapist, that is, the treatment person H operates the operation part 49 for the therapist. A door closing instruction is given, and it is indicated that a series of three-dimensional virtual space images in which the train door is closed as an event setting change needs to be displayed on the HMD 11. At this time, the CPU 45 proceeds to the next step SP6.

  In step SP6, the CPU 45 displays on the HMD 11 a three-dimensional virtual space image when the train departs from the station platform by sending a video signal for when the train departs to the HMD 11, and also outputs an acoustic signal for when the train departs from the headphones. 12 to output the 3D virtual space sound composed of the train departure sound corresponding to the 3D virtual space image from the headphones 12 and further to the body sonic device 4 for the stimulus control signal for the train departure. By sending, a bodily sensation stimulus such as vibration upon arrival at the train corresponding to the three-dimensional virtual space image and the three-dimensional virtual sound is given to the patient P through the body sonic device 4, and the process returns to step SP1 again to repeat the above-described processing. .

  On the other hand, if an affirmative result is obtained in step SP4, this means that the coordinates obtained by the operation command from the patient controller 3 coincide with the coordinates in the train, that is, the patient P In the three-dimensional virtual space image, it is shown that the train passes through the train door and gets on the train. At this time, the CPU 45 moves to the next step SP7, finishes the station home standby processing, and proceeds to the next step. Transition to boarding process.

(3) Boarding process Next, when the CPU 45 of the personal computer 5 gets on the train through the door of the train that is stopped from the station platform in the three-dimensional virtual space via the patient controller 3, according to the boarding process program, As shown in FIG. 11, the routine RT2 is started from the start step and proceeds to step SP21.

  In step SP21, the CPU 45 sends a video signal for boarding the train to the HMD 11 to display on the HMD 11 a three-dimensional virtual space video when the train is boarded, and the sound signal for boarding the train to the headphones 12. By sending out, 3D virtual space sound consisting of door closing sound, train running sound, departure announcement, etc. corresponding to the 3D virtual space image is output from the headphone 12, and a stimulus control signal for riding on the train By sending it to the sonic device 4, vibrations during train traveling corresponding to the 3D virtual space image and 3D virtual sound, touching feelings such as a person's touch, and a sense of collision are given to the patient P via the body sonic device 4. And move to next step SP22.

  At this time, in the three-dimensional virtual space, after the door is closed, a series of events in which the train departs from the station platform is performed.

  At this time, when the train is still at the station platform based on the coordinates in the train and the angle signal from the gyro sensor 10 in the three-dimensional virtual space, the HMD 11 displays the train platform from the train window as shown in FIG. A video screen 106 of a three-dimensional virtual space image that can be viewed is displayed. Further, the HMD 11 has a video screen 107 of a three-dimensional virtual space image that can be viewed inside the train as shown in FIG. 13 based on the coordinates in the train in the three-dimensional virtual space and the angle signal from the gyro sensor 10. Is displayed.

  In the case of this embodiment, for example, the video screen 107 treats the congestion setting according to the condition of the patient P in four stages of an unattended state, a sparse state, a moderate congestion, and a large congestion. The person H can be changed through the operation section 49 for the therapist.

  The video screen 107 shown in FIG. 13 shows a three-dimensional virtual space video when the therapist H changes the congestion setting in the train to a moderate congestion via the operation section 49 for the therapist. is there. Incidentally, FIG. 14A is a video screen 108 showing a three-dimensional virtual space image inside a train set in an unmanned state, and FIG. 14B is a three-dimensional virtual space image inside a very crowded train. FIG.

  At this time, the therapist H can change the viewpoint height setting viewed by the patient P in the three-dimensional virtual space via the operation section 49 for the therapist, and in the train corresponding to each patient P. The three-dimensional virtual space can be presented. In the case of this embodiment, the viewpoint height setting can be changed in three stages, for example, a three-dimensional virtual space image set at a default position (a preset value set in advance by the program) as an initial viewpoint height setting. Can be presented. The viewpoint height setting can be sequentially changed to a sitting three-dimensional virtual space image and a standing three-dimensional virtual space image based on an operation command from the operation section 49 for the therapist. Has been made.

  In the embodiment described above, the change of the viewpoint height setting is forcibly performed by the therapist using the operation section 49 for the therapist, but the present invention is not limited to this, and the viewpoint height setting is performed. In this case, since the patient P can change the viewpoint height setting, a horror scene desired by the patient P can be easily presented.

  In step SP22, the CPU 45 determines whether or not a next station arrival command has been given by operating the therapist operating section 49 as a change in event setting.

  If an affirmative result is obtained in step SP22, this means that the next station arrival instruction is given via the therapist operation section 49, that is, the therapist H changes the event setting in the three-dimensional virtual space. This indicates that the patient P is trying to experience the state when the traveling train arrives at the next station platform. At this time, the CPU 45 proceeds to the next step SP23.

  In step SP23, the CPU 45 sends a video signal for arrival at the next station to the HMD 11 to display a three-dimensional virtual space image when the train arrives at the next station on the HMD 11 and an acoustic signal for arrival at the next station. Is output to the headphone 12 so that the headphone 12 can output the three-dimensional virtual space sound upon arrival at the next station, such as a train stop sound, door opening sound, arrival announcement, etc. corresponding to the three-dimensional virtual space image. By sending a stimulus control signal for arrival at the next station to the body sonic device 4, body sonic stimulation such as vibration and contact with a person when the train stops corresponding to 3D virtual space video and 3D virtual sound It gives to the patient P via the apparatus 4, and moves to the next step SP24.

  In step SP24, the CPU 45 determines whether or not the train platform has been lowered from the open door of the train stopped in the three-dimensional virtual space based on the coordinates obtained based on the operation command from the patient controller 3.

  If an affirmative result is obtained in step SP24, this means that the coordinates obtained by the operation command given from the patient controller 3 coincide with the coordinates at the station home in the three-dimensional virtual space, that is, the patient P is the patient controller. 3 is shown in the three-dimensional virtual space image that the train passes the train door and gets off from the train to the station platform. At this time, the CPU 45 moves to the next step SP25 and finishes the above-described boarding process. Shift to station platform standby processing.

  On the other hand, if a negative result is obtained in step SP24, this means that the coordinates obtained by the operation command given from the patient controller 3 do not coincide with the coordinates at the station platform in the three-dimensional virtual space. The three-dimensional virtual space image indicates that the vehicle stays on the train. At this time, the CPU 45 proceeds to the next step SP26.

  In step SP26, the CPU 45 determines whether or not a door closing command is given from the therapist operation section 49 as a change in the event setting.

  If a negative result is obtained in step SP26, this means that the door closing command has not been given from the operation section 49 for the therapist, that is, the event setting is not changed and the train door remains open. This indicates that the HMD 11 is displaying the three-dimensional virtual space image, and at this time, the CPU 45 returns to step SP24 again.

  At this time, the personal computer 5 displays the 3D virtual space image in which the door of the train stopped at the station platform has been opened for a predetermined time or longer on the HMD 11, and the therapist H uses the operation section 49 for the therapist. For example, by outputting from the headphones 12 a three-dimensional virtual space sound that indicates a vehicle failure or an emergency stop by a suddenly ill person, it can be changed to an event setting for stopping operation.

  On the other hand, if a positive result is obtained in step SP26, this means that the door closing command is given from the therapist operation section 49, that is, the therapist H is operated by the therapist H. Indicates that it is necessary to display a series of three-dimensional virtual space images in which the train door is closed as a change in the event setting on the HMD 11. At this time, the CPU 45 returns to step SP 21 and returns to the above-described step. Repeat the process.

  On the other hand, if a negative result is obtained in step SP22, this means that the next station arrival instruction is not given through the operation section 49 for the therapist, that is, the therapist H runs the train in the three-dimensional virtual space. This indicates that the patient P is going to experience the state when he / she continues, and the CPU 45 proceeds to the next step SP27.

  In step SP27, the CPU 45 determines whether or not an emergency stop command has been given from the therapist operation unit 49 as a change in the event setting.

  If a negative result is obtained in step SP27, this means that an emergency stop command has not been given from the operation section 49 for the therapist, that is, the therapist H does not change the event setting in the three-dimensional virtual space. This represents that the patient P wants to experience the state of continuing running. At this time, the CPU 45 moves again to step SP22 and repeats the above-described processing.

  On the other hand, if an affirmative result is obtained in step SP27, this means that an emergency stop command has been given from the operation section 49 for the therapist, that is, the therapist H changes the event setting and trains in the three-dimensional virtual space. Represents that the patient P is to be forced to experience the state when the vehicle is urgently stopped. At this time, the CPU 45 proceeds to the next step SP28.

  In step SP28, the CPU 45 sends an emergency stop video signal to the HMD 11 to display on the HMD 11 a three-dimensional virtual space image when the train stops in the tunnel, and an emergency stop acoustic signal. By sending the sound to the headphone 12, a 3D virtual space sound such as an emergency stop sound of the train corresponding to the 3D virtual space image or an announcement indicating an emergency stop is output from the headphone 12, and further stimulation for arrival at the next station. By sending a control signal to the body sonic device 4, the body sonic device 4 can be used to generate a bodily sensation stimulus such as vibration during emergency stop corresponding to a 3D virtual space image and 3D virtual sound or a feeling of pressure from another person. It gives to the patient P and moves to the next step SP29.

  In step SP29, the CPU 45 determines whether or not a driving resumption command is given from the therapist operating section 49 as a change in event setting.

  If a negative result is obtained in step SP29, this means that the operation resuming instruction has not been given from the therapist operation unit 49, that is, the therapist H trains in the three-dimensional virtual space without changing the event setting. Represents that the patient P wants to experience the emergency stop state. At this time, the CPU 45 waits for a positive result in step SP29.

  On the other hand, if an affirmative result is obtained in step SP29, this means that the operation resumption instruction is given from the operation section 49 for the therapist, that is, the therapist H trains in the three-dimensional virtual space as a change in the event setting. Represents that the patient P wants to experience when the operation resumes, and the CPU 45 proceeds to the next step SP30.

  In step SP30, the CPU 45 sends a video signal for resuming operation to the HMD11 to display on the HMD11 a three-dimensional virtual space image when the train resumes operation in the tunnel, and also outputs an acoustic signal for resuming operation. By sending the sound to the headphone 12, the 3D virtual space sound composed of the start sound of the train corresponding to the 3D virtual space image and the announcement that the operation has been resumed is output from the headphone 12, and the stimulus control for resuming the operation By sending a signal to the body sonic device 4, a bodily sensation stimulus such as a vibration at the start corresponding to the 3D virtual space image and the 3D virtual sound is given to the patient P through the body sonic device 4, and the process returns to step SP22 again. The above processing is repeated.

  In this way, the phobia treatment system 1 is in front of Sakura 1-chome Station, Sakura 2-chome Station, No. 30 Building-mae Station, Minami-dori Station, Minami-dori 3rd Avenue Station, Midori intersection Station and Hall 50 Presents various 3D virtual space images to the station, 3D virtual space acoustics and physical stimulation, reaches the final station, Chuo-gai Station, and finally 3D at the entrance / exit of the subway station as shown in FIG. A virtual space image may be presented.

  Incidentally, in this phobia treatment system 1, as shown in FIG. 16, the therapist H displays the various three-dimensional virtual space images such as traveling on the subway through the operation section 49 for therapist according to the state of the patient P. The event setting can be changed to force the switching to the 3D virtual space image at the subway station entrance of the final station, and the burden on the patient P can be easily reduced by the therapist H at any time during treatment. Can do.

(4) Operation and Effect In the configuration described above, the phobia treatment system 1 uses the HMD 11 as a three-dimensional virtual space that reproduces the subway usage situation for a patient P who has a fear of the subway usage situation as a specific situation. The three-dimensional virtual space sound corresponding to the three-dimensional space image is output from the headphone 12, and the bodily sensation corresponding to the three-dimensional space image and the three-dimensional space sound is output to the patient via the body sonic device 4. By giving it to P, it presents a subway use scene that is a horror scene through the visual, auditory, and tactile senses of patient P, and feels as if patient P is facing the actual subway use scene. Can be given.

  In this phobia treatment system 1, the setting of the three-dimensional virtual space image, the three-dimensional virtual space sound, and the bodily sensation stimulation (that is, the congestion setting, the viewpoint height setting, and the event setting) By making it possible to change freely according to the state of the patient P being treated, it is possible to finely set a fear scene for each patient P, thus performing a treatment suitable for each patient P, and improving the therapeutic effect of the patient P. Can be increased.

  In other words, in the three-dimensional virtual space of the subway usage scene presented by the phobia treatment system 1, the therapist H uses the operation section 49 for the therapist, the cherry blossom 1-chome station that is a transit station from the first station, Nishidori Station, In each route from Sakura Nichome Station, No. 30 Building-mae Station, Minami-dori Station, Minami-dori 3rd Avenue Station, Midori intersection Station, and Hall 50 Mae-mae Station to Chuogai Station, the final station 3D virtual space image, 3D virtual space acoustics, and sensation stimulation can be changed by changing the person's congestion setting in 4 stages of sparseness, moderate sparseness, and heavy congestion. The setting can be made finely for each patient P, and thus treatment of the patient P who feels a fear of crowds in the subway use scene can be performed.

  In the three-dimensional virtual space of the subway usage scene presented by the phobia treatment system 1, the therapist H uses the therapist's operation unit 49 to arrive at the train, open / close the door, start the train, next to the train being boarded. Fear scenes that have a sense of fear for each patient P for 3D virtual space video, 3D virtual space sound, and body stimulation by being able to change to various event settings such as arrival at the station, emergency stop, forced termination, etc. Thus, various specific situations can be created in the subway usage scene, and optimal treatment can be performed for each patient P.

  Furthermore, in the three-dimensional virtual space of the subway usage scene presented by the phobia treatment system 1, the view height setting that the therapist H views the patient P in the three-dimensional virtual space can be changed by the therapist operation unit 49. By doing so, it is possible to finely set the 3D virtual space image, 3D virtual space sound and bodily sensation stimulation to a horror scene that has a fear sensation for each patient P, and thus to be seated or standing in the subway use scene On the other hand, the optimal treatment can be performed for the patient P who has a sense of fear.

  In the phobia treatment system 1, the patient P himself / herself operates the patient controller 3 to display on the HMD 11 a 3D virtual space image that is moving in the 3D virtual space. Thereby, in the phobia treatment using the virtual space which has been performed unilaterally under the initiative of only the therapist H, it is possible to give the patient P a higher sense of reality than before and to the patient P. Active treatment participation can be induced, and treatment can be concentrated to enhance the therapeutic effect.

  Moreover, in this phobia treatment system 1, since the physiological information of the patient P sent from the SSR measuring device 7 is displayed on the display unit 6 in real time, the physical change of the patient P is conventionally compared with the evaluation of the treatment. The physical change of each patient P, which has been performed through observation by eye, language report, and data from a questionnaire after treatment, can be easily and accurately applied to the therapist H based on the SSR as physiological information. Thus, an appropriate horror scene can be set while analyzing information on the physical change of the patient P in real time.

  Furthermore, in the phobia treatment system 1, the back stimulation applying means 23, the waist stimulation applying means 27, the upper arm stimulation applying means 31, the buttocks stimulation applying means 35, the forearm stimulation applying means 38 as the stimulation applying means of the body sonic device 4, and Conventionally, the lower leg stimulation applying means 41 is individually controlled and operated independently, so that a predetermined bodily sensation stimulation is applied only to a specific part of the patient P corresponding to the three-dimensional space image and the three-dimensional space sound. It gives you a sense of reality and allows you to concentrate and receive treatment to increase the therapeutic effect.
