What are the main devices in which VR is used?
Virtual reality (VR) technology mainly includes simulated environments, perception, natural skills and sensing devices. The simulated environment is a computer-generated, real-time dynamic three dimensional realistic image. Perception means that the ideal VR should have all the perceptions that a person has.
In addition to the visual perception generated by computer graphics technology, there are auditory, tactile, force, motion and other perceptions, and even smell and taste, also known as multi-perception. Natural skills refer to human head rotation, eye, hand gestures, or other human behavioral movements, which are processed by computers to match the participant's actions and respond to the user's input in real time and feedback to each of the user's five senses. Sensing devices refer to three-dimensional interaction devices.
Interactivity of VR
The interactivity of VR refers to the degree of user manipulability of objects in virtual reality and the naturalness of feedback from virtual reality, including real time. It is generated mainly with the help of specialized devices (e.g., operating grips, data gloves, etc.) to manipulate objects in virtual reality in a natural way, such as gestures, body postures, language, and other skills, as if they were in the real world.
