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.
Claims20
A method for cautioning a user of a head mounted display, the method comprising:
- receiving, by a processor, images of a scene within which the user using the head mounted display is present, wherein the scene includes a predetermined three-dimensional area;
- tracking, by the processor, location information of the user based at least in part on the images;
- dynamically determining, by the processor, that the user approaches an edge of the scene;
- and
- based on the determination, warning, by the processor, the user that the user approaches the edge of the scene.
A method for cautioning a user of a head mounted display, the method comprising:
- receiving, by a processor, images of a scene within which the user using the head mounted display is present, wherein the images are captured by one or more sensors secured to the head mounted display;
- dynamically determining, by the processor, that the user approaches one or more tangible obstacles based at least on the images;
- and
- based on the determination, warning, by the processor, the user that the user approaches the one or more obstacles.
A method for cautioning a user of a head mounted display, the method comprising:
- receiving, by a processor, depth data of a scene within which the user using the head mounted display is present, wherein the images are captured by one or more depth sensors secured to the head mounted display;
- dynamically determining, by the processor, that the user approaches one or more tangible obstacles based at least on the depth data;
- and
- based on the determination, warning, by the processor, the user that the user approaches the one or more obstacles.
