GB/T 38247-2019Information technology—Augmented reality—Terminology (English PDF)

2.1 General terms

2.1.1 Virtual reality

Multi-sensory integration of realistic vision, hearing, touch, smell, taste and so on generated by modern high-tech means with computer as the core

The digital artificial environment, the user interacts with the objects of the virtual world in a natural way by means of some input and output devices.

Ringing, resulting in a feeling and experience of being in the real environment.

2.1.2 Augmented reality

The use of additional information generated by modern high-tech means of computer-centric means to enhance the real world perceived by users

The generated information is superimposed into the real scene in a way that the physiological feelings such as sight, hearing, taste, smell, and touch are merged.

2.1.3 Enhanced virtual

Combine the geometric and physical properties of the physical objects in the real scene into the computer-generated virtual scene to form a virtual scene.

Line enhancement.

Note. Different from augmented reality, the enhanced virtual subject is the virtual world generated by the computer rather than the real world where the user is located.

2.1.4 Mixed reality

A technique for realizing the hybrid matching of a real scene and a virtual scene. The physical object and the virtual object coexist in the scene and can be delivered in real time.

Mutual, thus constructing a new environment in which real objects and virtual objects blend in real time.

Note 1. The ideal mixed reality is to achieve an exact match between the real scene and the virtual environment in terms of geometry, illumination, physics and interaction consistency.

Note 2. Augmented reality and enhanced virtual are two forms of mixed reality.

2.2 Technical terminology

2.2.1 Virtual object

A computer-generated object with a geometric shape, a specific format, or a specific behavior.

Note. The prototype can be a real object or a completely fictional object.
