The standard specifies how Augmented Reality and Virtual Reality (AR/VR) devices should be set up and used in the enterprise; in a manner that ensures Health and Safety (H&S) is maintained, H&S consequences are understood, and additional risks are not introduced. Within this concept of safe usage, there is particular focus on guidance around safe immersion (time) and safety in the workplace. This ISO/IEC standard: a) defines the concepts of AR, VR, the virtuality continuum and other associated terms such as Augmented Virtuality and Mixed Reality; a) provides guidance on setting up AR systems; b) provides guidance on setting up VR systems; c) provides guidance on safe usage and immersion in AR systems both in the consumer and enterprise domains; d) provides guidance on safe usage and immersion in VR systems both in the consumer and enterprise domains. This standard focuses on visual aspects of AR and VR. Other modes such as haptics and olfactory are not addressed within this standard. The standard covers both the hardware (the physical VR/AR head mounted displays) and areas of visual stimulus (the environments and graphics displayed in those headsets). The standard does not cover all possible visual stimulus scenarios; focus is directed toward those areas that are known to have implications on safe use. This specifically includes the source vection (visual illusion of self-motion in physically stationary VR/AR users) and/or motion (physical movement of VR/AR users) and associated safe use considerations.
