Definitions

  • the invention relates to the development of attractions and simulators for both games and entertainment, and for athletes and professional training in various fields, namely, virtual reality technologies, which, in addition to transmitting visual content to a person, also provide the possibility of its movement identical to the corresponding movement in a simulated reality.
  • the disadvantage of this invention is the rigid fixation of the entire surface of each foot on a flat surface, which significantly limits the possibility of transmitting the impressions that arise when moving in the real world: when running, jumping, climbing a steep slope, etc.
  • the objective of the invention is to provide, when simulating movements in virtual reality, such sensations that will most fully correspond to the sensations taking place in the real world.
  • FIG. 1 illustrates a bend of the sole and, accordingly, a change in the relative position of the heel and forefoot during normal walking.
  • FIG. 2 shows the degrees of freedom that must be implemented in the present invention.
  • FIG. 3 shows a possible embodiment of a device that implements the proposed method, and FIG. 4, a fragment of this device is given in close proximity to the place of fixation of the feet.
  • FIG. 5 shows another one of the many possible variants of the design of the device for implementing the proposed method.
  • the invention can be carried out by using a multi-link hinged-lever system and a set of sliders moving along special guides, as well as drives that provide the necessary linear and rotary movements in all the minimum 14 degrees of freedom (7 for each foot) and are presented, for example, stepper motors with gears and linear actuators (Fig. 3).
  • linear actuators provide the movement of each foot to the desired location in space by displacement along three spatial axes
  • the articulated link mechanisms coupled with devices for fixing the foot with the appropriate actuators provide the required spatial orientation of the foot and the necessary bend of the sole (Fig.
  • the parameters of the drives are selected so as to provide movement speeds for each degrees of freedom corresponding to the physical abilities of a person, and at the same time realize the corresponding efforts and moments taking into account dynamic effects. It is advisable to equip the devices for attaching the feet with sensors of forces and moments corresponding to the called degrees of freedom. Taking readings of these sensors at fairly short time intervals, it is possible to record in real time the current motility of a person on the simulator and, thus, determine the movements that he intends to make. Comparing these movements with the constraints dictated by the current landscape of virtual reality, it is possible to calculate the necessary control actions on all drives (linear and rotational).
  • the leg in virtual reality is on a solid surface
  • the corresponding sensor detects the presence of a force directed downward from the person
  • the vertical position of the corresponding actuator should remain unchanged. If the direction of this force changes to the opposite, then the actuator must begin to move upward according to the law of motion, which ensures the lowest possible value of this force.
  • this will be perceived by a person as his voluntary and natural movement to raise the leg, not constrained by any factors, including the weight and inertia of the actuator itself. That is, a person simply does not have to feel that his leg is in fact shackled by something.
  • FIG. 5 an example of an alternative embodiment of the described device is depicted, based on the support of a person’s feet on special retractable swing rods pivotally connected to devices for attaching to the sole in its front part and in the heel region.
  • the main thing is that the number of independent degrees of freedom (at least seven on each leg) does not change.
  • the corresponding coordinate transformations again come down to the simplest operations with 14th-order matrices. It should be noted that in any of the options shown there is a disadvantage associated with the limited ability of a person to rotate about the vertical axis.
  • the proposed method provides a technical result, which consists in obtaining a new quality - providing the necessary minimum conditions for creating, when simulating movements in virtual reality, a complex of sensations that are practically indistinguishable from those that a person experiences in real reality.

Abstract

L'invention concerne un procédé pour imiter les déplacements dans la réalité virtuelle grâce au positionnement des pieds sur des surfaces d'appui mobiles qui sont mises en mouvement par un système d'entraînement linéaire ou orientable ; au moins sept degrés de liberté sont prévus pour chaque pied. Dans le cadre de la mise en oeuvre de l'invention, on parvient à un résultat technique qui consiste à élargir la mesure de la perception d'une personne de ses sensations sur le dispositif d'entraînement qui sont tellement réalistes que la personne croit qu'elles sont réelles. A peu près chaque mouvement est perçu de façon réaliste : l'on peut marcher ou courir dans des directions aléatoires sur n'importe quelle surface, même fortement inégale et présentant des propriétés différentes (dure, souple, glissante), s'accroupir, se mettre sur la pointe des pieds, sauter, remonter des pentes raides ou des escaliers, et ce sans sentir le mécanisme attaché aux pieds. Le dispositif peut s'utiliser pour créer des appareils d'attraction ou d'entraînement, dans des jeux ou à des fins de divertissement, de même que pour des sportifs et dans le cadre d'entraînements professionnels dans différents domaines.
