Description

 The invention relates to computer games, space, sports, military simulators, and more specifically to a method of immersing a user in virtual reality and a device for its implementation.

 The invention can be used to entertain children and adults. Devices for computer games can be installed indoors, in the courtyard, in the halls for slot machines. The device can be used for education and training of the military, athletes and in training various specialties, such as police officers. The device may be useful for research purposes in the study of human behavior in computer virtual space.

 Virtual reality is a combination of means that make it possible for a person to have the illusion that he is in an artificially created world, by replacing the usual perception of the surrounding reality with the help of the senses by information generated by a computer. This is achieved using three-dimensional graphics and special information output devices that mimic the familiar connection of a person with the world. Currently, virtual reality is a completely independent area of computer technology.

 Virtual reality is what allows you to move in a three-dimensional world with six degrees of freedom and view it in real time. This means that the program sets, and the equipment recognizes six types of movement: back and forth, up and down, left and right, tilt up and down, roll left and right, and rotate left and right. Virtual reality is an artificial medium generated by a computer, which can be an imitation of physical reality or be a completely unusual and fantastic environment.

 Virtual reality provides the user with a rare opportunity to almost truly feel their presence in another world. In it, they can see each other, talk and interact, distinguishing colors, shapes and sounds. This complete immersion creates an impressive presence effect. This is achieved through the equipment used - a helmet with built-in headphones and a joystick that is sensitive to spatial movement.

 In the simplest version of a virtual reality system, contact with the virtual world is carried out through an ordinary personal computer monitor, which serves as a window to this world. Additional tools, such as the information glove used to manipulate objects in a virtual environment, and the visual interface in the form of a helmet-display, allow you to see only virtual space around, the picture of which will change when the joystick is manipulated, which aggravates the sensations and allows you to fully immerse yourself in this space .

 The tools that form virtual reality include a high-speed computer, usually including an accelerator of three-dimensional graphics from just a personal computer to supercomputers and virtual reality software, for example, VIRTUS VR, VIRTUS WALKTHROUGH PRO, SUPERSC APE VRT, VRCREATOR, etc.

 Means of displaying virtual reality, i.e. means of audio-visualization, are monitors of various types, helmets, displays HMD (Head Maunted Display) or CAVE (Cave Automatic Virtual Environment).

 Means for interactive interaction with virtual reality - traditional and non-traditional input-output devices, special three-dimensional mice, gloves, joysticks and tracking devices. For example, the Virtual Technologies CyberGlove glove tracks almost any movement your hand is capable of.

 Tracking devices allow you to determine the position of the user's arms, legs and torso and orientation in the real world and display them in the virtual world. Tracking systems differ according to the principle of motion detection - with mercury balancers, radio waves, ultrasound, laser, etc.

 The simplest set of tools for creating virtual reality is known, which was available 7-8 years ago (see, for example, the DOOM game by ID Software, "The Encyclopedia of Computer Games", St. Petersburg, 1995, pp. 119 - 122). This set contains a stationary computer, a color monitor that opens a “window” into the virtual world, which appears to be lying on the other side of the screen. A manipulator device such as a mouse, joystick, or keyboard makes it possible to control movement, rotation, and visibility in any horizontal direction of virtual space.

 In this game, a complete immersion in virtual reality does not occur, since the virtual space is visible through the "window", limited by the boundaries of the picture tube screen. Movement is controlled by the manipulator with a hand. The system does not reflect interactively the physical movements of the user in the virtual space.

 The increased power of computers and the more advanced means of audio visualization that have appeared have led to the creation of a device for displaying virtual reality, such as a stereoscopic monitor or projector, which a person puts on his head like a helmet or glasses and gets the opportunity to see a three-dimensional image (see, for example, the PC World magazine ", N 1, 1995, p. 164-175).

 In the specified device, the virtual world becomes full-sized, goes beyond the screen and surrounds a person. There is complete freedom of movement in the virtual space, an opportunity, in addition to horizontal viewing, to look at a certain angle up and down. Manipulators such as a three-dimensional mouse, "gloves" allow you to interact with objects. They either respond to this with a predictable response, or are deformed. This level of funds allows you to more fully immerse yourself in virtual space, feel yourself inside this virtual space and interact with objects.

 However, the control of objects and movement occurs with the help of manipulators and does not allow to fully identify movements in virtual space and in real space.

 Recent developments in the field of virtual reality provide almost complete immersion of a person in virtual space.

 A known method of forming virtual space is that they form a virtual space in which objects appear and move in a predetermined and random manner, display the generated virtual space to the user, and continuously convert the virtual space in accordance with real physical movements of the arm, leg, head, body and the human eye in real space, taking into account interaction with objects in virtual space.

 It is also known a device for immersion in virtual reality, containing means for creating virtual space in which objects appear and move in a predetermined and random manner, to which a means for displaying virtual space to a user and a unit for converting virtual space are connected in accordance with real physical movements of the arm, leg, head , torso and eye of the user in real space, taking into account interaction with objects in virtual space (see, for example, al PC Magazine / Russian Edition, N 6, 1995, p. 60 - 79).

 In this device for immersion in virtual reality as a means of displaying virtual space uses a modern helmet that allows you to track the position of the head. This information is transmitted to a computer - to a virtual space formation tool that calculates a screen image corresponding to this space. If the user looks up, sees the virtual sky, if down - the virtual earth, that is, an overview of any direction of the virtual space is possible. The possibilities of human interaction with virtual objects have increased. You can grab a three-dimensional virtual reality object and drop it, or take a three-dimensional object and deform it.

 But in this world of sufficiently developed hardware and software, a person is forced to imitate his movement in the "endless virtual space" with the help of manipulators. There is no complete immersion of a human user into virtual reality, because, interacting with the specified device, a person does not have the ability to freely move in real space with a helmet on his head. The real space surrounding the user during a game or training is usually limited to a small area where a person cannot freely move in any direction for a sufficient distance.

 The basis of the invention is the task of creating a method of immersing the user in virtual reality, in which the transformation of the virtual space in accordance with the real physical movements of the user on the generated real limited space will allow the user to move in a limited real space in steps to any side without restrictions and combine movements in real space with movements in virtual space, i.e. provide a more complete immersion in virtual reality.

 The basis of the invention is also the task of creating a device for immersion in virtual reality, in which the use of the platform to form a real limited space, the elements of which can move in the plane along the x and y axes, compensating for the user's movement in any direction, and the use of the virtual space transformation block in In accordance with the user's physical physical movements, it will ensure a more complete immersion of the user in virtual reality.

 The basis of the invention is also the task of creating a device for immersion in virtual reality, in which the use of devices mounted on the legs of the user, providing slippage of the legs on the surface, and a corset, mounted on a support, to support the user when sliding in real space, as well as the use of block conversion of virtual space in accordance with the actual physical movements of the user, will allow for a more complete immersion of the user in virtual reality.

a control unit that is connected to a virtual space forming means and to the input of which a sensor for determining the number, size and direction of steps is connected, and
means for compensating the movement of the user on the site from the starting point associated with the control unit.

 It is advisable that the means for compensating the movement of the user on the site from the starting point contain a conveyor, the tape of which was formed by a plurality of elements fixed with the possibility of rotation around its axis on a set of endless closed elements that are parallel to each other and interconnected by connecting elements, so that the distance between them is approximately equal to the axial size of the elements; conveyor drive connected to the control unit; means for rotating the conveyor elements in a direction perpendicular to its longitudinal axis to return the user to the starting point connected to the control unit.

in FIG. 7 is an embodiment of a support for securing a corset;
in FIG. 8 is another embodiment of a support;
A device for immersing a user in virtual reality comprises means 1 (Fig. 1) of forming a virtual space in which objects appear and move in a predetermined and random manner. As a means of virtual space formation 1, a computer with an accelerator of three-dimensional graphics is usually used.

 The means 1 is connected to the means 1 display virtual space to the user 3. As a means 2 display in the described embodiment, a helmet is worn on the head of the user 3 and containing two screens on liquid crystals to transmit images to the user, and headphones for transmitting sound.

 The device contains a platform that is designed to move user 3 on it in any direction for any number of steps when interacting with objects of virtual space.

 The device also includes means 4 for compensating the user's movement across the site away from the starting point in such a way that, interacting with the elements of the site, returns user 3 to the starting point "0" when moving along the X and Y coordinates or at an angle to them.

The platform is a conveyor 5. The approximate size of the conveying surface is 2 x 2 m ² .

 The conveyor belt 5 (Fig. 2) is made in the form of a set of elements 6, interconnected. In the described embodiment, cylinders placed rotatably around their axis on endless closed elements, which are used as flexible cables 7, with a gap relative to each other, are used as elements 6. The cables 7 are parallel to each other and the longitudinal axis X of the conveyor 5. The distance between adjacent cables 7 (Fig. 3) is approximately equal to the radius of the cylinders 6, while the distance between each two even cables and every two odd cables is approximately equal to the diameter of the cylinders 6. Cylinders 6, located on one cable 7, are located in the gaps between the cylinders located on the adjacent cable 7. The cables 7 pass through the connecting elements - brackets 8, which are installed between each two adjacent cylinders 6 located along axis X. The conveyor 5 is driven by a drive 9, which is connected to the control unit 10. On the side surface of the cylinders 6 are made notches 11 (Fig. 4).

 The means 4 for compensating the movement of the user on the site from the starting point contains means 12 for rotating the conveyor elements in a direction perpendicular to the longitudinal axis of the conveyor, which is made in the form of an endless closed tape 13.

 The specified tool 12 is placed between the upper and lower parts of the conveyor belt 5. The tape 13 (Fig. 1) is mounted on a shaft 14 mounted on bearings 15 and connected to the drive 16. On the tape 13 are made notches 17 that are in contact with notches 11 on the cylinders 6 conveyor belt 5, on which the user 3 is located. The lower and lateral parts of the conveyor belt 5, as a rule, do not come into contact with the belt 13.

 The device also contains a sensor 18 for determining the magnitude and direction of steps of the user 3 relative to the starting point "0" of reference, located in the immediate vicinity of the user 3 and connected to the virtual space conversion unit 1 and the control unit 10. As the sensor 18 in the described embodiment, a sensor is used that determines the size and direction of movement of the user relative to the site on infrared radiation, and a receiver of signals sent by the sensor.

 The sensor 18 determines the magnitude and direction of movement of the user in accordance with the actual physical movements of the arm, leg, head, trunk and eye of the user in real space, taking into account interaction with objects in virtual space. To do this, a number of sensors 19 - 23 are installed on user 3, which determine the position of the hands, head, trunk, legs and eyes of a person, respectively. In this case, the eye position sensor 23 is placed on the helmet 2.

 The manipulator 24 is usually placed in the hand of the user 3 and is connected to the tool 1.

 Another embodiment of the device for immersing the user in virtual reality is possible, which contains a platform 25 (Fig. 5) for sliding, intended for the user to make 3 walking movements in any direction when interacting with objects of virtual space. In this case, the pad 25 is a smooth surface.

 The device also includes means 26 for compensating the movement of the user's legs on the site near the starting point. In the described embodiment, ball skates are used as such means 26 (Fig. 6), which are worn on the legs of user 3. It is possible that roller skates (not shown in Fig. 6) or shoes having a low coefficient of friction are used as such means soles, for example Teflon.

 The tool 26 (Fig. 5) also contains a corset 27, which is worn on the user 3 during a session of immersion in virtual reality. The corset 27 is rigidly fixed to the support 28 with the possibility of rotation around its axis. The support 28 is movable, i.e. it is attached on a cylindrical hinge 29 to the ceiling 30 to allow the user to rotate about the Z axis. Any type of corset can be used as the corset 27.

 The device also contains a sensor 31 for determining the number, size and direction of walking movements made by the user on the site relative to the starting point of reference, located in the immediate vicinity of the user 3. In the described embodiment, the specified sensor is similar to the sensor 18. The output of the sensor 31 is connected to the control unit 32, which connected to the means 33 of the formation of virtual space. The output of the means 33 is connected to the means 2 for displaying the virtual space to the user 3.

 It is advisable that the platform 25 for moving the user had a concave shape (not shown in FIG. 5).

 A support embodiment is also possible when it comprises two posts 34 (FIG. 7) installed in a spacer between floor 25 and ceiling 30, which are interconnected by means of a rod 35. A cylindrical hinge 29 is attached to the rod 35.

 Another embodiment of the support is possible when it contains three rods 36 (Fig. 8), one end of which is rigidly connected to form a pyramid, and the other ends can be mounted directly on the ground, to the top of which a cylindrical hinge 29 is attached.

 An additional support can be fixed on the cylindrical hinge 29 (Fig. 5), for example, a manipulator 37 designed to place auxiliary devices on it for forming virtual reality and interacting with the user 3.

 The device for immersion in virtual reality is as follows.

 A computer forms a virtual space in which objects, such as walls of houses, trees, cars, animals, people, clouds, etc., arise and move in a predetermined and random manner.

 The generated virtual space is displayed on the screens of the helmet 2 (Fig. 1) to user 3, and the user sees a three-dimensional image of the virtual world.

 Carry out continuous transformation of virtual space according to the program. Since user 3 does not see the borders of the screen due to the perfect design of helmet 2, he has the illusion of being completely present in virtual three-dimensional space. He has a desire to actively interact with the objects of this virtual space, for example, touch the trees with his hands, move closer to the object, pick it up, dance with a virtual partner, fly in an airplane, etc.

 In accordance with the change in the position of objects in virtual space, the user 3 changes his position in real and virtual space by real physical movements of the arms, legs, head, trunk and eye.

 User 3, making real steps on the site, moves relative to the objects of the virtual space. Moreover, it shifts relative to the center O of the site. The sensor 18 determines the magnitude and direction of movement of the user 3 relative to the center and transmits this information to the unit 1 and to the drive control unit 10 of the conveyor 5 and the means 12. At the signal from the block 10, either the conveyor 5 or the conveyor 5 and the means 12 are turned on simultaneously.

 In case the user 3 has moved only along the X axis, only the conveyor 5 is turned on, which moves the user back to the point O. If the user has moved only along the Y axis, only the means 12 is turned on, the belt of which will rotate and rotate the cylinders of the belt of the conveyor 5, moving the user along the Y axis to the center O.

 If the user has moved at an angle to the X axis, then both drives 9 and 15 are turned on. In this case, the entire conveyor belt 5, consisting of cylinders, will move and move the user along the X axis, and the belt 13 will simultaneously rotate each of the moving cylinders in contact with it 6, which will move the user 3 on them simultaneously along the Y axis. The resulting movement will occur at an angle to the X axis.

 If user 3 deviates from the center O by an amount not exceeding the specified limits, for example 0.5 m, the drives will not turn on.

 When using the second embodiment of the device, the operation is as follows.

 A shoe is put on the legs of user 3 (FIG. 5), which allows the user to slip over the legs of platform 25. Set user 3 at the starting point on platform 25 and put on a corset 27 so that user 3 does not fall and can move relative to the starting point. When the user 3 makes walking movements on the platform, the corset 27 holds him at the starting point, while the legs slip relative to the platform 25. Thus, the user 3 can take an unlimited number of steps in any direction, remaining constantly in the same place in the physical space.

 In this case, the number and direction of steps are determined by sensors 31 and, in accordance with this information, block 32 recounts the new position of user 3 in virtual space and displays it to user 3, which makes it possible to form a feeling of free movement in virtual space.

 For completeness of tactile sensations when interacting with objects of the virtual world, a manipulator 24 is used.

 Since the function of moving in virtual space, previously performed by the hand with the help of the manipulator, is performed by the user 3 himself when walking, he has great opportunities for controlling objects with his hands and through the manipulators.
