The difference between VR and AR lies in definition, equipment and usage.
1. Definition difference: The Chinese name of VR is virtual reality, which is an artificially programmed virtual environment and a created virtual world. Special VR equipment is used to simulate people's visual, auditory and tactile sensations. The Chinese name of AR is augmented reality. Various cameras and sensors on the glasses can achieve in-depth understanding of space and have spatial positioning functions, which can perfectly integrate virtual information and content with the real environment.
2. Differences in equipment: Because VR is a pure virtual scene, it is more commonly used: position trackers, data gloves (5DT and the like), motion capture systems, data helmets, etc. Since AR is a combination of real scenes and virtual scenes, it basically requires a camera. Based on the pictures captured by the camera, it is combined with the virtual pictures for display and interaction.
3. Difference in usage: VR is mainly used for game entertainment. AR can be used in teaching, advertising, medical treatment, and industry.
Characteristics of VR and AR
Characteristics of VR: Immersion refers to the immersive feeling that the user has during use; interactivity means that the user can use sensors The device interacts with most objects in the virtual environment. Conceivability means that users can not only obtain real experiences in the virtual environment, but also fully use their imagination to create objects that do not exist in the real world according to their personal wishes.
Characteristics of AR: Integration of information between the real world and the virtual world. Has real-time interactivity. It is to add positioning virtual objects in the three-dimensional scale space.
