Anti-screen door effect intelligent type VR head-display device

Abstract

The invention relates to an anti-screen door effect intelligent type VR head-display device comprising a body, a headband, a support and two earflaps; two display mechanisms are arranged in the body;the display mechanism comprises a notch, a tracking mechanism, a moving mechanism and a display shell; the moving mechanism comprises a first motor, a buffer block, a first drive shaft, a wire coil, astay wire and two reset units; the tracking mechanism comprises a drive mechanism, a tracking plate, an infrared emitter and an infrared camera; the anti-screen door effect intelligent type VR head-display device drives the display shells to move through the moving mechanisms, thus changing the distance between the display shell and the human eye, and enabling the equipment to suit for populationof various visual sights; in addition, the tracking mechanism can track the eyeball positions, thus determining the visual field scope, rendering the center position of the visual field scope with the maximum resolution, carrying out fuzzy processing for other portions, preventing the screen door effect, reducing the CPU burdens in the body, and improving the equipment practicality.

Description

technical field [0001] The invention relates to the field of VR equipment, in particular to an intelligent VR head-mounted display device capable of preventing screen effect. Background technique [0002] VR head-mounted display device, full name of virtual reality head-mounted display device, uses a head-mounted display device to close people's external vision and hearing, and guides it to produce a feeling of being in a virtual environment. The principle of monitor display is that the left and right eye screens display the images of the left and right eyes respectively, and the human eyes will generate a three-dimensional feeling in the mind after obtaining this information with differences. [0003] Because VR headsets can bring people into a virtual environment, VR headsets are often used for simulating engineering design to achieve an immersive feeling through virtual experience, and to save costs by experiencing the engineering environment in the early stage of enginee...

Problems solved by technology

In the VR head-mounted display, the main limiting factor of the virtual reality field of view is the lens. In order to obtain a wider field of view and enhance the virtual experience, it is necessary to shorten the distance between the user's eyeball and the lens or increase the size of the lens, but using a thinner The lens, the distance between the lens and the display will increase, and the size of the head display will also increase. Using a thicker lens will shorten the distance between the display and the display, but using a thicker lens will cause geometric distortion and chromatic aberration , because of the enhanced zoom, there will also be a screen door effect (due to insufficient resolution, the human eye will directly see the pixels on the display screen, just like looking at things behind the screen window), which reduces the user's VR experience, even if a small amount of VR The head-mounted display eliminates the screen window effect by increasing the screen resolution, but this will increase the operating burden on the internal processor of the head-mounted display and increase the cost of the device. Not only that, due to differences in human eyes, there are myopia, For different conditions such as farsightedness, although the existing VR head-mounted display can be equipped with various glasses, in the experience process, the glasses will undoubtedly increase the burden on the user experience, thereby reducing the practicality of the existing VR head-mounted display device
