Abstract:
User interaction concepts, principles and algorithms for gestures involving facial expressions, motion or orientation of body parts, eye gaze, tightening muscles, mental activity, and other user 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 user actions in orthogonal axes is disclosed. Generation of command signals based on start and end triggers is disclosed.

Claim (Index 1):
A system for a user to control an electronic device, the system comprising:\n at least one sensor configured to provide a portion of at least one of\n i) head information (Head Info) indicative of at least one of motion and position of the user's head, \n ii) eye gaze information (Eye Info) indicative of at least one of motion and position of the user's eye gaze, and \n iii) facial expression information (FE Info) indicative of at least one of motion or position of one or more parts of the user's face; and \n at least one processor configured to\n i) detect a start trigger based on at least one of\n a. the Head Info reaching or crossing a first head threshold, \n b. the Eye Info reaching or crossing a first eye gaze threshold, and \n c. detection of a first FE that is active for at least a first minimum FE detection time, wherein the first FE is detected to be active when the FE Info reaches or crosses a first FE threshold and stays at or beyond the first FE threshold, \n \n ii) after detection of the start trigger, start generation of command signals based on at least one of the Head Info and the Eye Info, \n iii) after the start generation of command signals, start detection of an end trigger wherein the end trigger is detected when at least one of\n a. the Head Info is within a second head threshold for at least a minimum head POLA time duration, where the second head threshold is less than the first head threshold, \n b. the Eye Info is within a second eye threshold for at least a minimum eye gaze POLA time duration, where the second eye gaze threshold is less than the first eye gaze threshold, and \n c. detection of a second FE that is active for at least a second minimum FE detection time, wherein the second FE is detected to be active when the FE Info reaches or crosses a second FE threshold and stays at or beyond the second FE threshold, and wherein the second FE is detected to be active only after the first FE is no longer detected to be active, and \n \n iv) after detection of the end trigger, stop generation of the command signals and wait for detection of a subsequent start trigger.
