Camera based safety mechanisms for users of head mounted displays
First Claim
1. A method for cautioning a user of a head mounted display, the method comprising:
- receiving, by a processor, images of a scene of a physical environment within which the user wearing the head mounted display is present, wherein the scene includes a predetermined three-dimensional area in which the user is allowed to move around during use of the head mounted display;
tracking, by the processor, location information of the head mounted display based at least in part on the images as the user moves around the physical environment;
dynamically determining, by the processor, while content is presented on a screen of the head mounted display and the user is wearing the head mounted display, that the user is approaching an edge of the scene, the edge of the scene is defined by a boundary of the predetermined three-dimensional area; and
based on the determination, warning, by the processor, the user via the head mounted display that the user wearing the head mounted display is approaching the edge of the scene.

Abstract
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.

12. A method for cautioning a user of a head mounted display, the method comprising:
-
receiving, by a processor, images of a scene of a physical environment within which the user using the head mounted display is present, wherein the scene includes a predetermined three-dimensional area in which the user moves around during use of the head mounted display and wherein the images are captured by one or more sensors secured to the head mounted display; dynamically determining, by the processor, while content is presented on a screen of the head mounted display and the user is wearing the head mounted display, that the user is approaching one or more tangible obstacles in the physical environment based at least on the images, the determining includes analyzing the images to identify a boundary of the predetermined three-dimensional area and determining that the user is approaching the one or more tangible objects within the boundary; and based on the determination, warning, by the processor, the user via the head mounted display that the user wearing the head mounted display is approaching the one or more tangible obstacles. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for cautioning a user of a head mounted display, the method comprising:
-
receiving, by a processor, depth data of a scene of a physical environment within which the user using the head mounted display is present, wherein the scene includes a predetermined three-dimensional area in which the user moves around during use of the head mounted display and wherein the depth data is captured by one or more depth sensors secured to the head mounted display; dynamically determining, by the processor, while content is presented on a screen of the head mounted display and the user is wearing the head mounted display that the user is approaching one or more tangible obstacles present within a boundary of the predetermined three-dimensional area as the user moves around the physical environment, based at least on the depth data; and based on the determination, warning, by the processor, the user via the head mounted display that the user wearing the head mounted display is approaching the one or more tangible obstacles.
