Description
Technical Field
The invention relates to a virtual reality method, in particular to a visual redirection method of an immersive virtual reality system.
Background
Displays that produce virtual images are often used on display devices that are positioned near the eyes of a user. These displays are referred to as near-eye displays, for example, widely known as head-mounted displays. After wearing the head-mounted display, a user cannot visually perceive the real world and only can see the virtual world in the virtual reality system.
Virtual reality systems generally include a head mounted display, a host device, and a tracker device. The virtual reality system is in communication with the accessory device via an operation. The tracker device may enable a user to determine the relative position of the user in space using algorithms and sensors in addition to rotating in place in the immersive world while wearing the head mounted display. The tracker device can not only make the user have better immersion feeling, but also greatly reduce the dizzy feeling generated by the tracker device, and the asynchronous feeling of the picture caused by the displacement of the user completely disappears.
Virtual reality systems provide us with an infinite border virtual world, but in practice users are more tied to the real world. The amount of space displayed by the head mounted display is not meant to be ambulatory and the user may be outside the sensing range of the tracker device or hit a real wall at any time. Therefore, a method for enabling a user to walk in a limited real space synchronously with a virtual world in a virtual reality system is needed.
Disclosure of Invention
The technical problem to be solved and the technical task to be solved by the invention are to perfect and improve the prior technical scheme and provide the visual redirection method of the immersive virtual reality system, so that the user can walk synchronously with the virtual world in the virtual reality system in a limited real space. Therefore, the invention adopts the following technical scheme.
An immersive virtual reality system visual redirection method comprises the following steps:
1) connecting the virtual reality device with a main control device;
2) transmitting a video signal from the master control device to the virtual reality device;
3) transmitting a feedback signal recorded with the current virtual reality device positioning information from the virtual reality device to the main control device;
4) and adjusting the video information content transmitted to the virtual reality device by the main control device according to the feedback signal, and performing spatial distortion or displacement processing on part of the picture to realize real walking adaptive to the virtual world by a spatial transformation method.
Through a visual redirection method, partial picture space is distorted or shifted, so that the real world walking is matched with the virtual world, the illusion effect of synchronizing the position direction between the virtual world and the real world is realized, and better immersion experience is realized.
As a further improvement and supplement to the above technical solutions, the present invention also includes the following additional technical features.
The video information content comprises information of a door or a movable position outside a viewed picture, and the main control device realizes reasonable virtual displacement of the door or the movable position according to a signal fed back by the virtual reality device so as to realize space transformation. The door or the position to which the door can move is reasonably and virtually displaced, so that the space transformation between the real world and the virtual world is realized.
The space transformation method comprises the transformation of angles and/or displacements, and the steering angles and/or displacements in the virtual world are processed by the main control device, so that the steering angles and/or displacements in the real world are different from the steering angles and/or displacements in the virtual world to avoid obstacles. And correspondingly displacing and/or adapting the angle through adjusting the angle and/or the displacement according to the corresponding relation between the virtual world and the real world.
When the virtual world walks in a straight line, displacement and angle of the real world are properly adjusted through calculation and adjustment, so that circular arc walking in a closed space is realized to avoid a closed wall in the real world and an obstacle in the middle of a closed place; the virtual world is a straight line walking, and when the straight line of the current corresponding direction and position in the real world is just a straight line path, the angle is not adjusted. An adaptation method for realizing straight line walking in a virtual world.
The virtual world and the real world are both straight walking paths but have different distances from touching the obstacle or the wall, and the step distances of the virtual world and the real world are converted to realize corresponding adjustment of touching the obstacle at the same time. The method can realize vivid touch effect, makes people difficult to distinguish the difference between virtual reality and the real world, and has better effect.
In the virtual world, the two sides of the virtual world are provided with obstacles and move forward in a zigzag mode when the obstacles are touched, and no matter how large the zigzag angle is, the virtual world can be processed into turning around and turning back when a closed boundary is touched, and the angle and the step pitch are calculated and adjusted while the real world is walking, so that the virtual world walks between two opposite walls and is converted into the virtual world which turns back through a 90-degree arc between two adjacent walls. The zigzag forward in the virtual world can be effectively realized in the closed space, and the effect of forward walking can be realized all the time.
The virtual reality device comprises a position tracker, a head-mounted display and a handle, wherein the position tracker is distributed in a real place for realizing virtual reality so as to realize comprehensive position tracking of a user. The position tracker is arranged in a real place to realize comprehensive position tracking of a user, and realize information feedback of the main control device so as to realize calculation of position and angle adaptability adjustment.

The square closed space occupies a small area and is not interfered by the outside, and 2 sets or 4 sets of position trackers are distributed diagonally, so that the comprehensive and effective position tracking can be realized.
The head-mounted display is connected with a main control device through an HDMI video line to transmit video signals, is connected with the main control device through a 3.5mm audio line to transmit audio signals, and is connected with the main control device through a DC3.5 power line to obtain a power supply; the position tracker and the handle are connected with the main control device in a 2.4GHz wireless mode to transmit positioning information and handle key information. HDMI video line transmissible ultra-clear video picture realizes the immersive effect easily, through 3.5mm audio signal transmission audio signal, acquire power, position tracker and handle through DC3.5 power cord and adopt 2.4GHz wireless transmission locating information and handle button information, the technology is mature, stability is good.
The side length range of the square closed space is between 2.5 and 3.5 m. The suitable smaller closed space occupies a small area, is low in cost and can meet the simulation of virtual world walking.
Has the advantages that:
1. by the method, large-scale walking in the virtual world can be realized in a narrow closed space, and unlimited walking in the large-scale virtual world can be experienced without establishing a large real space by a user;
2. because the virtual world and the real world realize adaptive algorithm adjustment, when the virtual world touches a wall, the real world also touches the wall, so that accidental touching of the wall or other obstacles in reality is not needed to be considered, and the immersive experience effect is more vivid;
3. compared with the prior art, the virtual reality device greatly improves the problem of space limitation of real space positioning, and simultaneously, due to the fact that planned limitation is performed on the action of a user, even if the user cannot see the real world after wearing the head-mounted display, the user is not afraid of colliding with obstacles outside the defined real space, and the safety of the user after wearing the head-mounted display is improved.
