Description

Virtual reality large-range omnidirectional walking technical scheme

Technical Field

The invention relates to a technical scheme for experiencing wide-range omnidirectional ambulation in a virtual reality scene.

Background

The virtual reality technology brings the experience person with a virtual scene through a 3D display technology, so that the scene seen by the experience person is like a real environment, the virtual reality gradually enters the life of common people, and the future demand can be explosively increased. At present, virtual reality equipment is becoming mature, and a virtual reality host can capture the position and the direction of virtual reality sensing equipment (such as a handle and the like, the same below) through space positioning equipment (such as a base station or an antenna and the like, the same below), map the position and the direction to a virtual scene, and interact with the content in the virtual scene.

The virtual reality is characterized in that immersion feeling and carrying-in feeling are provided, wherein the immersion feeling of a scene at a first human visual angle is the strongest and the most vivid, in the existing virtual reality technology, an experiencer controls a main corner in a virtual scene to move forwards by 1 meter by means of an input device (such as a handle), the forward movement of a visual field of the main corner of the scene by 1 meter is realized through a software algorithm, but the experiencer does not move actually, the scene changes or shakes severely, and the experiencer can be dized just like a person who walks a mountain bike, a visual organ sees the movement, a perception organ perceives the body not to move, and the two conflict, namely motion sickness. The best method for solving motion sickness is that an experiencer walks forward by 1 meter, the visual field of the main corner of the virtual scene also moves forward by 1 meter, and the same is true for other directions. Then the problem comes that you have so much real space to 1:1 "feel" the virtual scene. At present, the motion of an experiencer within a few square meters (the real activity space is limited) is mapped to a virtual scene through a space positioning device to solve motion sickness in a virtual reality scene in an instant moving mode, but the experienceable activity range of the virtual scene is fixed within the few square meters, even the virtual scene can be 'appreciated' through shaking the head in place for 360 degrees, and the immersion of the virtual reality is seriously influenced. How to map people to virtual reality in a mode closest to real walking (including walking and running, the same way below) to realize wide-range omnidirectional walking in a virtual scene and fully embody each position and visual angle in the scene is a huge problem.

Disclosure of Invention

Technical problem to be solved

In order to solve the problem that the experiencer does not comfortably and conveniently walk on the actual original place in the current market, but the walking (or running) travel distance and the walking direction are mapped into a virtual scene so as to realize a scheme of wide-range omnidirectional walking in the virtual scene, the invention sequentially solves 3 technical problems:

1. comfortable and convenient walking in situ

2. Planar omnidirectional in-situ walking

3. Mapping in real-time the face orientation of an experiencer into a virtual scene

The technical scheme that the virtual scene is not occupied in a large actual space, so that an experiencer can really feel that the virtual scene is occupied and the experiencer wants to walk to and then walks to, and experiences different positions and visual angles is provided.

Technical scheme

The technical scheme adopted by the invention for solving the technical problems is as follows: a virtual reality experience technical scheme.

Firstly, the treadmill walks in situ, and the treadmill on the market can realize the in-situ walking at present, but the research of authors shows that the realization mode of the two rollers and the middle running board of the treadmill is two-end rolling friction, a large area in the middle is sliding friction, the friction force is large, the mechanical treadmill is difficult to travel, and the electric treadmill solves the difficulty in traveling, but the running is at the cost of high energy consumption, high repair rate and high abrasion (sliding friction). The author designs a walking plate which is totally in rolling friction, the walking plate is composed of a plurality of circular shafts, frames and caterpillar bands, a plurality of professional bearings or rollers with very small friction force are respectively arranged on the circular shafts, two ends of each shaft are respectively inserted into holes of the frames, and all the shafts between the frames are wrapped by the caterpillar bands. Experience person directly steps on the track, and the track moves backward through the rolling friction with bearing or roller when advancing, and speed is the same with experience person's the speed of advancing, and frictional force is little, and it is comfortable to advance, need not take off shoes or wear what purpose-made shoes or equipment, just so can be very comfortable, very convenient on the spot walk.

The design idea of the author comes from the idea that people can walk towards any direction, but a person can only walk towards one direction at a certain moment, and the change of the direction is the next moment. The lower part of the frame of the walking plate is connected with a plate, the upper part of the plate does not touch a crawler, the central shaft which can rotate is connected at the central position of the bottom of the plate, the rotation is realized through a bearing principle, a specific realization mode can be a deep groove ball bearing or a thrust ball bearing and the like, which are mature technologies. The driving mode of the rotation can be manual or non-manual, and the scheme is not limited. The manpower is to push a fixed driving point which does not rotate along with the walking plate by a certain part of the body so as to achieve the rotation effect; the non-manual operation is just to press keys or induce and drive a rotating motor. However, it should be pointed out that after the virtual reality head display (the display part of the virtual reality host) is worn by the experiencer, the real environment is invisible, for the sake of insurance, walking needs a handrail, the handrail is not enough regardless of manual driving or non-manual driving, and an author designs a boosting support ring which is fixedly connected with a base and surrounds the upper half body (non-contact) of the experiencer, so that the double functions of a driving point of 360 degrees and the handrail are achieved, so that the proposal recommends energy conservation, environmental protection and low repair rate, and the manpower driving rotation mode of entertainment and fitness is also considered. The boosting support ring height suggestion is located a little below the elbow of a person in a natural state, so that the boosting support ring can be used for boosting and supporting the part below the elbow and above the palm of the person to experience, and hands holding the virtual reality induction equipment are liberated.

Connect a circular hardboard at walking board frame, the face flushes with the face of walking, the optional position of face (in virtual reality host computer space positioning equipment scanning range), place a device that can fix virtual reality response device, fixed orientation of putting response device is the same with experience person's front orientation, experience person like this, walking board, the panel, response device is as a whole, no matter what angle is arrived in experience person's rotation, response device's orientation remains the syntropy with experience person's front orientation throughout. The orientation of the experiencer and the orientation of the sensing equipment can be transmitted back to the virtual reality host machine through the capture of the space positioning equipment at any time, the orientation of the experiencer and the orientation of a main corner in a virtual scene are always consistent through a virtual reality content design algorithm, when the experiencer walks, only a signal of advancing is needed to be given to the virtual reality host machine, the key triggering or the body sensing triggering is a mature technology, and the scheme is not limited. As long as the traveling speed in the virtual scene is set, the walking motion of the experiencer can be mapped into the virtual scene in a ratio of 1 to 1, and different positions and visual angle feelings can be experienced without halation.

Advantageous effects

The method has the advantages that an experiencer can comfortably and conveniently move in situ without occupying a large actual space, experiences fresh feeling and visual angle impact force brought by any different positions and visual angles in a virtual scene in the maximum range, avoids motion sickness through high-reduction-degree reality and virtual mapping, is low-carbon and environment-friendly in the whole process, and gives consideration to entertainment and fitness.
