Abstract
An eye tracking interface system for generating communication and control functions as a result of pre-defined eye gestures is disclosed. The system includes a detecting device adapted to detect bio-electromagnetic signals generated by eye movements. A first processor receives the detected bio-electromagnetic signals, and generate tokens corresponding to said pre-defined eye gestures. A second processor receives the tokens, and generates command signals based on a protocol correlating tokens to desired command signals. Thereafter, a user interface responds to said command signals, and provides control functions in response to said command signals.
Claims8
A method for determining the 3D position of a gaze point comprising the steps of:
- detecting signals associated with eye position from each eye;
- processing said detected signals from each eye to determine the gaze point in 3D;
- and
- determining whether the 3D gaze point is located at a point outside of a presentation area.
A method for determining the 3D position of a gaze point comprising the steps of:
- detecting signals associated with eye position from each eye;
- processing said detected signals from each eye to determine and store a normative fixated distance for a user's gaze at an object;
- further processing said detected signals from each eye and determining when the 3D gaze point of said user is located at a point outside said normative fixated distance of said object;
- and initiating a command signal in response to said determination.
