Description

  The present invention relates to an apparatus that allows a subject to experience virtual reality with higher reality.

  Devices that allow a user, a subject, to wear a head-mounted display and experience virtual reality are provided. In these apparatuses, a virtual object can be arranged in a virtual space to show a virtual world to a user. Such a virtual reality device is used for a wide range of uses, for example, when it is used for an attraction of a theme park, or when it virtually walks in a building that is predicted to be completed.

  However, since the virtual reality device remains in the visual virtual world and is not accompanied by a bodily sensation, there is a problem of lack of reality. In order to solve this problem, there has been proposed an apparatus that provides a user with a bodily sensation and gives the user a bodily sensation so as to match the virtual reality image.

  For example, Patent Literature 1 discloses a system that detects an interaction between a virtual object in a virtual space and a user and gives a haptic effect to the user. According to this system, since a tactile sensation is given to the user, a virtual reality with higher reality can be provided.

  Patent Document 2 also discloses a system that can provide the same effect using an illusionary tactile force sense induction device.

It is an example of the working room 30 by other embodiment.

1. Overall Configuration FIG. 1 shows the overall configuration of a virtual reality device according to an embodiment of the present invention. In this embodiment, a user 2 who experiences virtual reality is seated on a chair 4 and restrained by a belt (not shown) or the like. The user 2 is attached with a head-mounted display (HMD) 6 that is a video display unit. The video control means 8 outputs a virtual reality video to the HMD 6. Therefore, the user 2 sees the virtual reality video by the HMD 6.

  A staff 10 is arranged near the chair 4. The staff 10 works on the user 2 (swing the chair 4, hit the wind, etc.) in accordance with the virtual reality video that the user only has. The instruction control means 12 outputs an instruction to the staff 10 so that the action by the staff 10 matches the virtual reality video. The instruction display unit 14 displays this instruction. Therefore, the staff 10 can act on the user 2 by looking at the instruction displayed on the instruction display unit 14. In this way, the user 2 can experience a realistic virtual reality world by giving vibration and the like together with the virtual reality video.

  FIG. 2 shows the structure of a set (structure) in which the virtual reality device is mounted. An introduction chamber 20 and a work chamber 30 are provided. An inlet door 22 is provided in the introduction chamber 20. A separation door 24 is provided between the introduction chamber 20 and the work chamber 30. Instead of the separation door 24, a curtain, a screen, or the like may be used.

  The introduction room 20 is provided with a chair 4 with a caster that can be moved, a desk 28 for providing an atmosphere as a set, a shelf 29 and the like. In this embodiment, since the user wants to experience a haunted house as a virtual reality, the desk 28 and the shelf 29 are props for giving a haunted house atmosphere. Although not shown in the figure, a poster or the like that arouses fear is affixed to the wall of the introduction chamber 20.

  When the separation door 24 is opened, the chair 4 can be moved to the work room 30. The work room 30 is provided with a monitor 32 for displaying instructions to the staff, a computer 34, and a rack 36 on which tools for work are placed.

FIG. 3 shows the inside of the introduction chamber 20. The entrance door 22 is visible in the center. In addition, shelves and posters are visible.

2. Virtual reality experience The provision of a virtual reality experience for users will be described below. In this embodiment, the process is divided into a preparation stage until the user wears the HMD and a main stage after the HMD is worn.

2.1 Preparation Stage The user is guided by the staff and enters the introduction room 20 through the entrance door 22. At this time, the user sees the actual interior as shown in FIG. 3 and feels as if he is in a haunted house.

  Subsequently, the staff seats the user on the chair 4 and restrains the body (including the limbs) with a belt or the like. At this time, the staff gives the user an emergency stop switch 27 (see FIG. 4) that is OFF when grasped and turned ON when released, and causes the right hand or left hand to grasp it.

  In the virtual reality experience, when the user cannot withstand this and wants to stop the experience, the emergency stop switch 27 can be stopped to stop the emergency stop.

  Further, as shown by the one-dot chain line in FIG. 1, the staff puts white sheets on the user and wears the HMD and the headset. In this embodiment, a completely closed type HMD (a type of HMD in which no actual scenery can be seen) is used. The staff presses a switch (for example, provided in the HMD) that starts the reproduction of the virtual reality video after confirming that the user has securely attached the HMD. Further, the staff opens the separation door 24 after confirming that the user has securely attached the HMD. Thereby, the staff can see the instruction | indication of the monitor 32 through the opened door.

2.2 This Stage When the start switch is pressed, the computer 34 outputs a virtual reality image to the HMD worn by the user, and outputs an instruction to the staff on the monitor 32 of the work room 30.

  FIG. 5 shows the hardware configuration of the system. A memory 42, a monitor 32, a hard disk 44, an HMD 46, a headset 47, an emergency stop switch 27, and a start switch 48 are connected to the CPU 40 of the computer 34. The hard disk 44 stores an operating system 50, a virtual reality program 52, a virtual reality video / audio 54, an instruction video 56, and the like.

  The virtual reality program 52 exhibits its function in cooperation with the OS 50.

  A flowchart of the virtual reality program 52 is shown in FIG. The CPU 40 determines whether or not the start switch 48 has been pressed (step S1). As described above, the staff puts white sheets on the user, confirms that the user has put on the HMD 46 and the headset 47, and then presses the start switch 48.

  When the start switch 48 is pressed, the CPU 40 reads out the virtual reality video / audio 54 and outputs it to the HMD 46 and the headset 47 (step S2). Therefore, a virtual reality image is displayed on the HMD 46, and sound corresponding to the virtual reality image is output from the headset 47.

  The beginning of the virtual reality video is a video viewed by a person restrained by the chair 4 in the introduction room 20. Therefore, the user can smoothly immerse in the virtual reality world because the match between the real scenery and the virtual reality image that has been viewed up to now is high.

  In order to improve this match, the beginning of the virtual reality video is produced so as to match the interior of the actual introduction room 20, the desk 28, the shelf 29, the color of the wall, the poster, and the like. In the virtual reality video, the guided actual staff appears as a video. At this time, the virtual reality image and the reality of the worn clothes and shoes are the same. When the staff appearing in the virtual reality video and the actual staff cannot be the same person, it is preferable to make the person as similar in appearance as possible.

  Furthermore, it is unpredictable what kind of clothes the user is wearing. Therefore, it becomes difficult to match the reality with the virtual reality as in the case of the staff. Therefore, in this embodiment, the same white sheets as the virtual reality are covered so as to hide the clothes worn by the user. In this way, by preparing an image covered with white sheets as a virtual reality image, it becomes easy to match the reality and the virtual reality image.

  The HMD 46 includes an acceleration sensor. The CPU 40 receives the output of the acceleration sensor, determines which direction the user is facing, and outputs a virtual reality image in the direction. Yes. Therefore, when the user moves his / her face forward / backward / left / right, a virtual reality image in that direction is displayed on the HMD 46.

  FIG. 7 shows a virtual reality image when the user is facing forward. A virtual reality image of the sheet 100 and the staff 10 covering the user sitting on the chair 4 is visible.

  Subsequently, the CPU 40 reads out the instruction video 56 and outputs it to the monitor 32 so as to synchronize with the virtual reality video presented to the user (step S3). As a method of synchronizing the two, it can be realized by attaching time stamps to both videos continuously and performing reproduction according to the time stamps for synchronization. Instead of continuous time stamps, time stamps may be provided at predetermined intervals (for each group of videos) for synchronization.

  The monitor 32 is provided in the work room 30. Therefore, the staff in the work room 30 can see the instructions displayed on the monitor 32. Further, by opening the separation door 24 as described above, the staff in the introduction chamber 20 can also see the instructions.

  An example of the instruction video displayed on the monitor 32 is shown in FIG. The screen is divided into four parts, and front, back, left, and right characters are displayed in each area. “Front” is the virtual reality video that the user sees when the user is facing forward, “Back” is the virtual reality video that the user sees when the user is facing backward, and “Left” is the virtual reality video that the user is facing left The virtual reality video viewed by the user when the user is present, and “right” is the virtual reality video viewed by the user when the user is facing the right.

  The staff can grasp what virtual reality image the user is currently viewing by viewing the instruction image. Under each area, instruction display units 60, 62, 64, 66 are provided. On the instruction display units 60, 62, 64, and 66, instructions for the staff are displayed in characters. In the instruction display unit 60 corresponding to the “previous” image area, an instruction for a work performed by the staff from the front side of the user is displayed. In the instruction display unit 62 corresponding to the “rear” image area, an instruction for a work performed by the staff from behind the user is displayed. Similarly, the instruction display unit 64 corresponding to the “left” image region and the instruction display unit 66 corresponding to the “right” image region respectively display instructions for the staff to perform from the left side and the right side of the user.

  Subsequently, the CPU 40 determines whether or not the user has turned on the emergency stop switch 27, that is, whether or not the hand has been loosened (step S4). When the user turns on the emergency stop switch 27, the CPU 40 stops outputting virtual reality video to the HMD 46 and outputting audio to the headset 47. Further, the output of the instruction video 56 is also stopped, and an indication that an emergency stop has occurred is displayed on the monitor 32 (step S6).

  If the emergency stop switch 27 is not on, the CPU 40 determines whether or not the virtual reality video / audio 54 has been reproduced to the end (step S56). If it has been played to the end, the process ends. If the virtual reality video / audio 54 to be reproduced still remains, step S2 and the subsequent steps are repeated.

  FIG. 9 shows an instruction video when the reproduction proceeds. Here, an instruction is given to put the foot on the chair leg. Since this instruction is displayed on the instruction display unit 60 corresponding to the “front” screen area, it can be understood that the staff only has to turn in front of the chair and put his / her leg on the chair leg.

  Also, as shown in FIG. 9, a number (“9” in the figure) is displayed before the character indicating the instruction. This instructs the staff to perform this action after 9 seconds. As shown in FIG. 10, in the virtual reality video, a person is moving to the front side of the chair 4. At this timing, the number becomes “0” and the leg of the chair is touched. Thus, the user can experience the virtual reality world with reality not only through video and sound but also through vibration.

  Also, as shown in FIG. 11, an instruction is given to the staff to go in front of the user and send the wind with a fan. This corresponds to the fact that the separation door 24 is opened at this moment in the virtual reality video.

  After that, the chair 4 is pushed by the staff and moved to the work room 26. In the meantime, in the virtual reality video, the video moving in the haunted house is played, and the staff gives vibrations when moving. Even after moving to the work room 26, the user is made to experience virtual reality in the same manner as described above.

In this embodiment, the instruction video 56 does not include sound. Therefore, although the staff knows what kind of video the user is currently viewing, he / she cannot know what kind of sound he / she is listening to. Therefore, as shown in FIG. 12, the audio given to the user in the virtual reality video / audio 54 is shown as characters. In FIG. 12, the virtual reality video / audio 54 allows the staff to know that the user is listening to the sound of “Let's go now” from the headset 47 at the right ear. In addition, the number attached after "Let's go now" is the number of seconds until the sound is output.

3. Other
(1) In the above embodiment, an instruction is displayed on the monitor 32. However, instead of the monitor 32, each staff member may wear an HMD (a type in which reality can be seen) and display instructions.

(2) In the above embodiment, the virtual reality sound that the user is listening is displayed on the monitor 32 as characters. By doing so, there is an advantage that the user who is waiting for the experience does not inadvertently leak the voice. However, if there is no such problem, the virtual reality sound may be output from the speaker so that the staff can hear it.

(3) In the above embodiment, the virtual reality world is experienced while the user is restrained by the chair 4. However, the present invention can be applied even when the user is restrained by the stretcher 5 as shown in FIG. A bed may be used instead of the stretcher 5. Also, the present invention can be applied to a case where a user is restrained by a vehicle such as a roller coaster.

  In addition, by restricting the user, the field of view from the user is limited, and it becomes easy to increase the matching between the real landscape and the virtual reality landscape. However, if this is not a problem, the user need not be restrained.

(4) In the above embodiment, the introduction chamber 20 and the work chamber 30 are provided separately. This is because if the user views the instruction video on the monitor 32 before wearing the HMD, the reality is lost.

  However, if the staff wears the HMD instead of the monitor, the operation can be performed only in the work room 30.

  Further, it may be performed only in the work chamber 30 as shown in FIG. In this example, a curtain 25 is provided in the work room 30 to hide the monitor 32. After the user wears the HMD, the curtain 25 is opened so that the staff can see the instructions on the monitor 32.

  Furthermore, in the work chamber 30 of FIG. 14, the curtain 25 may not be provided. In this case, when the user enters the work room 30, nothing is copied on the monitor 32, or a video other than the instruction video (for example, a video related to virtual reality) is recorded. After the user enters the working room 30 and wears the HMD, an instruction for the staff is displayed on the monitor 32.

(5) In the above embodiment, the instruction screen is displayed in four areas. However, the display may be divided into three or less and five or more areas.

  Further, only the screen in the direction in which the user is looking may be displayed as the instruction screen.

(6) In the above-described embodiment, a switch configured not to make an emergency stop when grasped but to make an emergency stop when loosened is used as an emergency stop switch. Thereby, even if it is a case where it loses consciousness, an emergency stop can be made.

  Note that an emergency stop may be performed by pressing a switch.

(7) In the above embodiment, the user 2 wears the completely closed HMD 46. However, you may make it mount | wear with HMD which can see the actual external world. Further, the virtual reality video may be displayed on an external display instead of the HMD 46.

(8) In the above embodiment, white sheets are used as the covering member, but sheets of other colors may be used. Further, instead of the sheets, cloth, clothes, ski wear, diving suits and the like may be used as the covering member. Furthermore, the user may be put in a box or the like, and the box may be used as a covering member.

  In any of the above cases, it is preferable that the actually used covering member and the covering member provided in the virtual reality are visually the same (similar).

(9) In the above embodiment, as a staff user's approach to the user, use a fan, etc. You may be made to work on it. In addition, the staff may be encouraged to give a sign of the person by being at the side.
