Gesture based user interfaces, apparatuses and control systems

Abstract

User interaction concepts, principles and algorithms for gestures involving facial expressions, mental activity, and other body actions are disclosed. User interaction concepts, principles and algorithms for enabling hands-free and voice-free interaction with electronic devices are disclosed. Apparatuses, systems, computer implementable methods, and non-transient computer storage media storing instructions, implementing the disclosed concepts, principles and algorithms are disclosed. Gestures for systems using eye gaze and head tracking that can be used with augmented, mixed or virtual reality, mobile or desktop computing are disclosed. Use of periods of limited activity and consecutive body actions in orthogonal axes is disclosed.

Dependencies are inferred from the claim text.
