Method and System for a User-Following Interface
First Claim
1. A user-following interface system comprising:
- one or more projectors adapted to project one or more images onto one or more selected surfaces in a real environment, wherein the one or more selected surfaces are selected from a plurality of surfaces;
a user tracking module adapted to track positions of one or more users in the environment; and
a controller coupled to the one or more projectors and the user tracking module, the controller adapted to select the one or more surfaces based on the positions of the one or more users in the real environment, and to provide information to the one or more projectors suitable for allowing the one or more projectors to project the one or more images onto the one or more selected surfaces.

Abstract
Techniques are disclosed for projecting an image onto a surface suitable for interaction with a user while avoiding user occlusion, and while correcting for distortion due to oblique projection. The displayed image moves to a suitable surface at a suitable size and orientation as a user moves around an environment, resulting in a user-following interface. Surfaces are selected in which the projected interface is not occluded by the user or other objects in the environment. Displayed images may be interactive, and moved into an interaction area on a suitable surface that is convenient for the user. The interaction area may or may not coincide with the display area. Adaptation of the projected interface is allowed so that the content of the display and the style of interaction widgets are modified based on distance from the user and orientation of the user with respect to a projected interface.
