Interpupillary distance: Difference between revisions

Revision as of 06:38, 24 March 2015

Interpupillary distance or IPD is the distance between the pupils of your eyes. There are two types of IPDs: Real IPD and Virtual IPD.

Real IPD

Real IPD is the actual distance between the center of your eyes' pupils in real life. Any Head-mounted Display require this measurement to accurately position the virtual camera outputs on the screen in front of the user's eyes. The outputs have to be directly in front of both of the users' eyes. Any deviation can cause eye strain.

Virtual IPD

Virtual IPD is the distance between the 2 virtual eyes (cameras) in Virtual Reality. This number can change the Sense of Scale of the objects in the virtual environment in relation to the user.
