CAMERA BASED SAFETY MECHANISMS FOR USERS OF HEAD MOUNTED DISPLAYS

摘要

The disclosure provides methods and systems for warning a user of a head mounted display that the user approaches an edge of field of view of a camera or one or more tangible obstacles. The warning includes presenting audio and/or displayable messages to the user, or moving the display(s) of the head mounted displays away of the user's eyes. The determination that the user approaches the edge of scene or a tangible obstacle is made by dynamically tracking motions of the users through analysis of images and/or depth data obtained from image sensor(s) and/or depth sensor(s) secured to either the head mounted display, arranged outside of the scene and not secured to the head mounted display, or a combination of both.
