Virtual reality glasses, or VR goggles, are eyewear which enables the wearer to view computer-generated images in stereoscopic 3D, in VR CAVES.
Virtual reality glasses and VR CAVES are growing in popularity with engineers, designers, architects and other professions, as they have clear benefits over head mounted displays (HMDs).
VR glasses are lighter and more comfortable to wear than HMDs, and less disorientating or isolating, all of which allow users to work in VR for longer times without ill effects.
Accurate colourimetry: Enhanced contrast and a high rate of residual light
Radio-Frequency (RF) link with the simulation computer: monitoring, real-time remote control and 3DoF accelerometer
Head-tracker targets specifically designed for the glasses
Universal IR mode, compatible with most standard IR protocols
The applications for VR glasses are broad: for example, if the wearer is using virtual reality for architectural purposes then they will be able to view a computer generated building at different angles, walkthrough and around it, with their point of view changing as if they were in a real building.

How do VR glasses work?
Stereoscopy
The glasses contain polarised lenses which show two images, one per eye, which the brain combines into one. In this, they are similar in operation to the 3D glasses used in cinemas to watch 3D films These combined images give a 3D depth and Virtual Reality. This technique is called stereoscopy. Manufacturers of virtual reality glasses, like our partner Volfoni, provide high-quality VR glasses with the following enhanced capabilities:
