Abstract
User gaze information, which may include a user line of sight, user point of focus, or an area that a user is not looking at, is determined from user body, head, eye and iris positioning. The user gaze information is used to select a context and interaction set for the user. The interaction sets may include grammars for a speech recognition system, movements for a gesture recognition system, physiological states for a user health parameter detection system, or other possible inputs. When a user focuses on a selected object or area, an interaction set associated with that object or area is activated and used to interpret user inputs. Interaction sets may also be selected based upon areas that a user is not viewing. Multiple devices can share gaze information so that a device does not require its own gaze detector.
