3D Blu-ray playback

ability to watch the content of 3D Blu-ray disks in 3D very much like in 3D IMAX

360-degree videos and photos

when you watch a 360-degree movie, you can see the panorama all around you, yet interacting with objects is limited. 360 degree photos are a static version of the same experience.

display resolution

every display consists of pixels – tiny “bulps” packed densely next to each other. The bigger the resolution, the greater number of those “bulps” and the better quality of the visuals.

IPD (Interpupillary Distance)

distance between centers of the pupils of the eyes


infrared radiation


an electronic circuit board which is one of the main components of a personal computer


personal computer

room-scale VR

VR systems able to track the player in any pose, anywhere in a designated area

screen-door effect

every display consists of pixels – tiny, densely packed “bulps”. If their density is not big enough, the display produces blurry visuals. In the worst case you can see every pixel individually.


a technique giving the ability to see images in 3D. The principles of that are described here.


all objects from the real world, which can be tracked by the VR system to propel their counterparts in the VR. Those include representations of: pistols, shotguns, bats, rackets etc.

USB (Universal Serial Bus)

one of the ways of the communication between computers, gaming consoles and other devices. The signal is transmitted over the cable and through the standardized plugs and sockets. USB can be also used for charging batteries or as a source of power.
