Virtual reality system based on a smartphone and a tilt mirror

摘要

The invention relates to systems for mobile virtual reality and specifically to systems for mobile virtual reality performing six-degrees-of-freedom tracking of the user position using a smartphone camera as the only imaging device. The invention provides a marked-based VR system where markers can be easily deployed and a calibration procedure may be performed in a less complex way. A marker-based positional tracking system for virtual reality is provided. The system includes a camera mounted on a user; and a floor marker. The floor marker may be provided on an unrollable carpet and denote a safe walkable area for the user. A slanted mirror may be mounted in front of the camera so that the view of the camera is redirected downwards. Also, the camera may be a smartphone camera.
