Leiditech recommends VR glasses protection devices and solutions
VR glasses use headworn display devices to block people's visual and auditory perception of the outside world, guiding users to create a sense of being in a virtual environment. The display principle is that the left and right eye screens display images of the left and right eyes respectively, and the human eye obtains this information with differences, which creates a sense of stereoscopy in the mind.
Generally speaking, VR head display devices can be divided into three categories: external head display devices, integrated head display devices, and mobile end head display devices.
From a technical perspective, sensory interaction is the soul of VR. Good somatosensory interaction must have accurate positioning, sensitive response, and comprehensive somatosensory recognition. At present, there are five recognition technologies: laser positioning, infrared optical positioning, visible light positioning, visual Motion capture, and inertial sensor Motion capture. The CPU calculates attitude positioning based on the data transmitted by these sensors. In order to prevent dizziness, VR glasses require the image Refresh rate to reach 90Hz, which has a high requirement for the GPU's computing power.
From a market perspective, mobile head display devices are gradually being phased out due to their poor experience (low resolution, poor sensors), and generally exist in scenarios where there are thousands of offline fast experiences. And all-in-one VR head display devices are the trend of future VR. It is estimated that by 2023, integrated head display devices will account for 59% of market shipments; External head display devices will account for 37.4% of market shipments; The remaining part belongs to the thousand mobile terminal display devices.
In the future, it is likely that our TV, pad, and mobile devices will all disappear and be replaced by VR three-dimensional interactive operating systems. We will no longer stay in the simple plane interaction between fingers and screens, but in the future, it may be multi-dimensional interactive manipulation such as three-dimensional space, gesture, and voice. To achieve these complex interactive manipulations, the importance of sensors is self-evident.
