Virtual reality systems in wide applications
VR glasses are widely used in computer games, but also used in other applications, including simulators and trenażerach. They include a stereoscopic head mounted display (provide a separate image for each eye), 3D glasses, stereo sound, and very often also the sensors are tracking the head movements, which may include gyroscopes, accelerometers, magnetometers, structured lighting systems, etc. in Addition to the entertainment apps (games or watching video in 3D) this kind of system is often used for training doctors, especially surgeons, and professional soldiers.
The requirements that should match 3D glasses
The creation of virtual reality systems, in particular 3D glasses not trywialną case. Poorly designed devices will not give the full effect of three-dimensionality, and in addition, can cause the user nausea, dizziness or eye pain. VR glasses should have low latency, so that the image respond quickly to movement. The image must have a large enough resolution that the pixels were not visible, especially if the VR system that we use, has a wide viewing angle. A key element of any 3D glasses are lenses digital block image with flat panel displays for the user's eyes to provide a realistic and not tiring on the eyes image.
Smartphones as a device for the VR system
Some VR glasses use smartphones to control virtual reality and display three-dimensional images. This is not an unreasonable approach. First, almost everyone has this kind of device. Secondly, modern mobile phones have high quality displays that have sufficiently low latency and high resolution to see how the display in the glasses 3D. In modern smartphones built-in sensors such as accelerometers or gyroscopes, digital, facilitating their use in the virtual reality system.
