1.VR / AR overview

Virtual reality technology is a development direction of simulation technology. It is a combination of simulation technology and computer graphics, human-machine interface technology, multimedia technology, sensing technology, network technology and other technologies. It is a challenging cross-technology, Research fields and frontier disciplines. Virtual reality technology (VR) mainly includes aspects such as modeling, perception, natural attributes, and sensing equipment. Modeling is a three-dimensional, realistic image generated by a computer. Perception is ideal. VR should have the perception of all people. In addition to the visual perception generated by computer graphics technology, there are also perceptions of hearing, touch, force, and motion, and even olfactory and taste, which are also called multi-sensing. Natural attributes refer to other behaviors such as human eyes, gestures, walking, etc. The computer processes data that is compatible with the movements of the human body, responds to user input and output in real time, and outputs them to the human features.

Augmented reality technology is a technology that seamlessly combines virtual world information with real world information. It is physical information (such as vision, taste, and touch) that was originally estimated in a certain time and space of the real world. , Sound and other information), superimposed after computer simulation, the virtual information is mapped to the real world and perceived by human senses, so as to achieve a sensory experience beyond reality. The real environment and virtual object information are superimposed on the same picture in space at the same time, achieving a state where reality and virtual coexist. It not only shows the real world information, but also displays the virtual information at the same time. The two kinds of information complement and superimpose each other. In visualized augmented reality, users can use the head-mounted display to synthesize the real world and computer graphics multiple times, and then they can see the real world around it.

The AR system has three outstanding features: ① real-world and virtual information integration; ② real-time interaction; ③ adding positioning virtual objects in a three-dimensional scale space. AR technology can be widely used in many fields.

The difference between VR / AR

VR and AR have different application fields, technologies and market opportunities, so it is of great significance to distinguish the differences between the two. .
