The technical field Useful model refers to the field of instrumentation and is intended for use in gaming machines, simulators and systems using simulation devices.

State of the art

It is known that in recent years, in scientific research, the game industry, and simulators, tools for creating virtual reality are widely used, by which they mean a set of tools that allow creating a 1: 3 person the illusion that he is in an artificially created world, by replacing the usual perception of the surrounding reality ( using the senses) - computer-generated information (L1-L75L105L11)

This is achieved by using three-dimensional graphics and special input and output devices that mimic a person’s usual connection with the surrounding world. Most often, gloves (L1, L2, L, p. 66,220), joysticks (A10, L11) and other control devices are used as such devices 5 transmitting computer information about the movement of the RCCH (its position, orientation, effort and TP), slots (Al, A2, A6, A10, A11) that allow you to see and hear the virtual world using the computer output signals supplied to the stereo video systems and stereo headphones of the helmet, is equipped with th position sensor head output is connected to a control computer inputs (A1, A2, A6, A10 and All

The most important task of such systems is to achieve the maximum correspondence of the sensations of a person using a simulator to the actual real sensations.

Great achievements in software maintenance are also known (see, for example, Encyclopedia of Computer Games, Filio Press, St. Petersburg, 1955). The space of dynamic virtual reality Fantastic scenes is formed with the most unusual features for the user: movements in the plane of the turns, braking, axial turns, diving, cabling shooting and. (A1, A2, A6, A7, A10 and AI). To increase the presence effect, eye-mounted stereo telemonitors and stereo headphones placed in a helmet are used as video and VCHDU1O simulations, which completely isolates the user from the visual and sound environment actually surrounding him and immerses him in the world of virtual reality without external interference (A1, A6, A7, A10, A11). To enhance the simulation, the governing bodies are made according to Forne and the principles of use are very close to real ones. To further develop the direction of virtual reality, the above simulation tools are supplemented with mechanical influences on the user. Thus, to increase the reliability of sharp turns, braking, falling, and accelerating, mechanically changing elements are introduced into the game equipment, for example, pressure sensors in different parts of the player’s shaft and / or player’s chair (L1) acting on the player in accordance with the image and his (player's) control actions One of the great achievements is the introduction of the head position sensor gender zovtelya is located in the helmet, which is put on the head of the player. The essence of its action is based on the theory of G.L.Komendantov’s orientation of a person in space, according to which the orientation is carried out according to two components a) relative to the gravitational vertical C, the vector of gravity) and b) relative to landmarks (M, L5). Orientation with respect to gravity is provided by the work of the balance organs, external receptors and the motor apparatus. The vestibular apparatus, receptors of the skin and muscles, internal organs, of which the functions consist in maintaining equilibrium in three-dimensional space or correcting imbalances (L4, A5), are of great importance. Thus, the irritation of receptors caused by a change in the action of the force of gravity, determines the functioning of the structures of the central nervous system, combined into a single functional system. In this case, there is a whole perception of the position of the body in space (a complex visual image plus a complex of sensations caused by mechanical stimuli). The installation of the human head strictly according to the vector of gravity is provided by cervical, postural and oculomotor unconditioned reflexes. When performing displacements in real space (for example, flight), a person’s orientation provides the same oiotema as in terrestrial conditions; at the same time, a person experiences the influence of the resulting gravity and the numerous inertia forces that arise during airplane evolutions. In this, a person unconsciously seeks to combine the axis of his body and, especially, his head with the resulting forces acting on him. However, visual control of the earth’s surface, assessment of the position of the horizon and showing The use of navigation instruments allows the pilot to restore the spatial position of the aircraft. Thus, the orientation of a person with complex spatial movements, such as flight, is an active mental and intellectual process. When in virtual reality, the image of the spatial position of a person who is physically at rest is formed using only a visual analyzer - by perceiving movements relative to computer-simulated visual images. The functional spatial orientation system resulting from the evolution of the creature is not implemented in this case, because there is no physiological support - 2 visual information by other analyzers - The effect of presence in 1 virtual space is significantly weakened due to the operation of spatial images only at the level of representations (a subzective image of a real object) One of the options for enhancing the presence effect is to search for the approach of the system of artificial stimuli to the evolutionarily developed functional system of the spatial orientation of a person, i.e. the introduction of adequate deyotviyu natural stimuli other analyzers. Then, the artificially generated visual information will be supported by mechanical influences corresponding in strength and direction, and the assessment of one’s spatial position in the virtual plane will require less intellectual expenditure and the use of abstract thinking from the user (player), since a natural combination of natural subconscious orienting mechanisms in space will work and read the above, the introduction of the head position into the player’s helmet helmet was a great improvement by the existence of pre-existing simulators SLBluchu}) - Being in a virtually motionless seat, the player nevertheless naturally responds with the movements of his body and, first of all, his head, to changing virtual reality. The player deflects his head forward or backward when sharply braking or accelerating, deviates to the sides during turns , goes down or up with a change in height, and t "n. In this case, the head position sensor transmits information about these movements to the control inputs of a computer game, which accordingly changes nyat video and audio plot of virtual reality i.e. small instinctive changes in the position of the head (with a position sensor located on it) will visually increase, respectively, affect the player more strongly; they will cause stronger sensations), bringing them closer to the natural sensations of real events. This sensor (taking into account the natural reaction of a person to maintain his vertical position) for the first time used and reinforced the real physical movement of the player when moving in virtual reality space. To further increase the effect of virtual reality in the ACE DRIVER models of NAMKO (Japan) (LI), the player’s seat was used with little left and right radial movement associated with the rotation of the control knobs in this case with the car’s steering wheel But it is closest to the claimed technical the decision on the number of common essential features simulator of movement on the UN game MAGIC CARPET (.266). It is selected as a prototype and contains a computer with an installed virtual reality game program, a helmet with video and audio systems and a head position sensor, a player’s control device, for example, a joystick and / or button control unit and a movable base for placing the player, and the computer’s audio and video outputs are connected with video and audio inputs of the player’s helmet systems and outputs of the control device and sensor

the player’s head position is connected to the control inputs of the computer. A player with a helmet on his head and a control device in his hands stands on a movable base, it is a platform suspended on flexible stretch marks and insured against falling around the moving platform, it is fenced and a belt worn on the player is also attached with stretch marks to the specified fence. The simulator works as follows “In accordance with visual and sound content of the current virtual reality, the player using the player’s control device controls his position (the position of an imaginary apparatus movements in which the player is in virtual reality space) in the space t “e-he changes directions and the speed of the jump jumps, shoots and instinctively makes the corresponding movements. In this case, the movements of the moving base occur directly from the player’s movements. Since the suspension is flexible and the player’s stability in a standing position it is low, the player’s movements will be strengthened by the suspension, the player will feel large vestibular signals and the position sensor on his head will transmit signals to the computer further enhancing his sensations of movement, especially of the acceleration braking turns “This solution was chosen by us as a prototype. It is described in detail in (L10). Despite all the relative simplicity of the prototype, it has several disadvantages.

Limited area of effective use Virtual reality illusion with enhanced work of the vestibular apparatus can be obtained only with limited small amplitude changes in the player’s position. But a significant number of games are connected with the movement of a person on aircraft where a much wider range of movements is possible (with aerobatics figures, barrel loop, etc.). In this case, a person sits in the cockpit.

The standing position of the user is inconvenient and does not correspond, for example, to the above examples of games with aircraft. The vestibular apparatus is far from fully involved i.e. the illusion of virtual reality is poorly supported by adequate simultaneous exposure to the vestibular apparatus.

The essence of utility models.

The objective of this useful model is to reduce the listed disadvantages of the prototype (and analogues), namely: to increase the reliability of the simulation to expand its functionality by effectively reinforcing the illusion of the generated audio and video signals with an adequate effect on the player’s vestibular apparatus. This problem is solved in a well-known simulator of human movement in virtual reality space containing a computer with an installed virtual reality game program helmet with video and audio oiotems with the head position sensor, the player’s control device and a movable base for placing the player, the video and audio outputs of the computer are connected respectively to the video and audio inputs of the helmet and the outputs of the player’s control device and the head position sensor are connected to the computer inputs, significant changes and additions are made to the simulator, namely creole mounted on a movable base and

- I am

rotary and / or reciprocating movement of the base; the drive input is connected through one output (displacement output) of the player’s control device and the output is on the movable base

In addition to that) to eliminate the uncertainty in the reflection of the spatial position, the output of the player’s head position sensor can be connected to the control input of the computer through a key that blocks the sensor signal when the movable base deviates from the original base by more than 70 degrees (so that movement in the chair is not perceived as movement of only the head inside the cab).

In addition, to increase the efficiency and simplicity of safety, the output of the player’s control device can be connected to the drive input through the controller, which provides video and audio virtual information pairing with the mechanical movement of the player’s chair, as well as the correct stop of the game if the player’s predetermined limit values are exceeded. , to increase convenience and security, the chair can have a tethered system for attaching the player to it (player fixation during chair movements)

In addition, to ensure safety, the player’s tethered system can be made with the possibility of emergency detachment, for example, using a quick release parachute lock.

In addition, a second control device may be introduced into the simulator, comprising an emergency stop switch located outside the movable elements; the operator has its output connected to the controller.

In addition, to increase safety, a controller can create an emergency automatic stop circuit for creole containing a logic addition, the inputs of which are connected respectively to the outputs of the player’s status sensor, emergency stop switches of the player’s control device and second control device, and the output is connected to the circuit input disabling actuator actuators In addition, to ensure hygiene, the simulator helmet may have a removable hygienic liner. tsya drawings (Figures 1, 2), where: Fig -1 - an example block diagram of the simulator of FIG 5 2 - Example tethered sistemyNa Figure 1 the notation: 1- computer installed with a virtual reality game,

The simulator consists of computer 1 with the installed virtual reality game program, PI video audio outputs of which 10 and I are connected respectively to the video and audio systems 3 and 4 of the helmet 2 In the helmet 2 there is also a sensor: head position 5. A control device for player 6 is attached to the seat 15 from joystick75 of the button control unit 8 and the state sensor 9. At least one transfer output (in the example of FIG. 1, two) 12a of the player’s control device is connected to rotation drives 17 and / or reciprocating movement 18 through the matching controller the control drives 17 and 18 the outputs of the controller 22 are connected to the corresponding drives The drives 17 and 18 are kinematically connected to a movable base 165 on which the creole is mounted 15 The output of the head position sensor 5 is connected to the input of computer 1 through the key 21 the outputs of the player’s state sensor and switch emergency shut-off 13 connected to the input of the matching controller 22 connected by a communication line 24 to the computer 1 The controller 22 has emergency stop inputs 20 to which the environmental switches are connected oh, the shut-offs of both control devices 6 and 23 of the player’s state sensor 9. The simulator works as follows: “The player sits in the chair 15 and attaches to it using the attachment system, which will be put on the helmet 2, then the operator will turn on the computer 1 installed by the virtual reality game program According to the content on the video system 3 and audio system 4 of the player’s helmet 2 receives dynamic information that requires an immediate reaction of the player — Using the player’s control device, the player produces Corollary appropriate in his view of the current situation: it speeds up your letate / 1ny apparatus tornozit turns, soars upwards swoops down falls flips

shoots.-For these maneuvers, the player uses the joystick 7 and the button control 8. Each maneuver has its own control and its output signal which from the outputs 12 and 12a of the control device 6 are fed to the inputs of the computer 1.

At least one moving output 12a of the control device 6 (in our example, FIG. 1, two outputs) is connected to the inputs of the matching controller 22. The outputs of the controller 22 are driven in accordance with the control signals, drives 17 and 18, i.e. player 15, together with the player sitting in it, begins either to turn or move forward (backward), downward), or to carry out these movements at the same time. The controller 22, through the communication line 24, coordinates the visual-sound and physiological information received by the player through all his senses.

The player receives a huge gamut of harmonized sensations, significantly exceeding the naturalness obtained in the prototype. Through the communication line 24 of the controller 22 with the computer 1, the controller 22 is loaded at start-up and the settings of the actuators 17 and also the controller settings are changed, if necessary.

In order that the movement in the chair is not perceived by the user (who has a head position sensor 5 installed in the helmet 2) as soon as the head movement inside the cab when the movable smell 16 deviates from the initial horizontal position by more than 70 degrees, the key 20 disables the head sensor output 5 from the input of the computer. The control key 21 comes from the output 24a of the controller 22. In this case, the latter monitors the position of the player’s cabin 15 according to the control signals of the controller 22 Limit of 70 degrees. due to the technical characteristics of the head rotation sensors and existing software.

The attachment system (example -) consists of the upper 25 belts attached to the back of the chair with two ends and the other two to the locking system 28 of the upper belt of the foot 26, fixing the position of the player’s legs using the lock 29 of the foot straps, and the waist belt 27 passing, for example, through the brackets mounted on the creole 15 at the hips of a player whose ends are closed by the upper lock of the tethered system 28. The belts are made with the possibility of independent adjustment of length.

The device is used as follows: The player sits in chair 15, adjusts the length of all belts 25,26,27 according to his size, then fastens the leg belt with a lock 29, and the upper and waist belts with a lock 28. Locks are selected such as quick-release, for example, parachute. If you need to urgently release the player, the player, or the operator quickly unfastens the locks 28 and 29, freeing the ends of all the belts at once. The player can get out of the chair. For an emergency stop at the inputs 20 of the emergency stop of the controller 22, the output signal of the sensor for the state of the player 9 (objective state of the player), or the switches of the emergency stop of the control devices of player 6 (player decision) or operator 23 (operator decision) will appear. Logic generated in controller 22 emergency stop circuit will immediately turn off the actuator of the actuators 17 and 18. In this case, the chair can be reset to its initial position manually.

A computer with an installed virtual reality game program can be executed on a PC-486 0X4,100 MHz, 16 MB RAM, and 420 mV HDD; SRAM 512 KB; CD-ROM DRIVE - UMITJ Long Bound cardlVEK 1 interface protokol (VIP) Card. Joystick - may be of the type Quid: Shot The button control unit can be built on conventional microswitches. A player’s status sensor can be simply a button that is constantly pressed (the player) controls himself and the situation “If he faints or is confused, he releases this button, which is equivalent to signaling a player’s bad state. A helmet can be used5 for example, like VEX 1 from Forte technologies, Inc (USA) . Drives: For example, an electromechanical drive on contactless torque motors DG, M PO -1-0.8-2 (L8) A motor control system - for example, based on a Siemens 80 C 167 microcontroller (L9). The matching controller can be made on the basis of the Siemens CS167-1E game controller. Coordination of the control outputs of the matching controller with the drives is done using RS485 protocol and the controller with a computer using RS 232 protocol. Chair design - like an airplane, can not cause difficulties Fixing device: example of it performance described in this application (figure 2). The key is electronic, of any type, controlled. Thus, the proposed design is industrially applicable. The prototype of the inventive simulator is made and is being tested, and the results obtained. Tests confirm the confident achievement of the task - a fundamental increase in the degree of adherence of the sensations of a virtual reality game to the sensations of reality. The claimed solution, in our opinion, satisfies all the criteria presented to utility models. It is new - we do not know such a solution from available sources of information. The solution is extraordinary, has an inventive step. It is not obvious to a specialist. This statement can be confirmed by the following arguments.

player movements

These contradictions were resolved by the claimed utility model by a complex of non-obvious mutually necessary essential features in the limiter in the head position sensor circuit by a system of special safety measures by introducing a player state sensor; a special scheme of the tethered system by the introduction of an emergency stop unit for monitoring the simultaneous serviceability of all elements of the simulator and an additional emergency stop switch outside the moving elements of the simulator.
