Abstract: This application includes disclosure of methods, systems, apparatuses as well as principles/algorithms that can be implemented on computer readable medium, for defining user gestures, interpreting user actions, communicating and confirming user intent when communicating with electronic devices. A system for controlling an electronic device by a user is disclosed that includes a microprocessor and a communication link. The microprocessor runs control software for receiving a first signal indicative of a first action of the user, receives a second signal indicative of motion or position of a part of the user's body, and generates a command signal for the electronic device based on a user gesture performed by the user. The communication link communicates the command signal to the electronic device.

Abstract: A hands-free controller, a facial expression management system, a drowsiness detection system and methods for using them are disclosed. The controller monitors facial expressions of the user, monitors motions of the user's body, generates commands for an electronic device based on the monitored facial expressions and body motions, and communicates the commands to the electronic device. Monitoring facial expressions can include sensing facial muscle motions using facial expression sensors. Monitoring user body motions can include sensing user head motions. Facial expression management can includes monitoring user facial expressions, storing monitored expressions, and communicating monitored expressions to an electronic device. Drowsiness detection can include monitoring eye opening of the user, generating an alert when drowsiness is detected, monitoring proper usage of the device, and generating a warning when improper usage is detected.

Abstract: Method and apparatus is disclosed for a user to communicate with an electronic device. A processor receives user intention actions comprising facial expression (FE) information indicative of facial expressions and body information indicative of motion or position of one or more body parts of the user. When the FE or body information crosses a first level, the processor starts generating first signals based on the FE or body information to communicate with the electronic device. When the FE or body information crosses a second level, the processor can end generation of the first signals or modify the first signals. An image processing or eye gaze tracking system can provide some FE information or body information. The signals can modify attributes of an object of interest.
