Abstract
A method and system are provided for determining if a control button on a touch screen controller (TSC) was inadvertently touched. A user gaze point is determined using gaze detection apparatus, and the level of functional significance of the control button is identified. User gaze boundary values for the control button are then determined, and the gaze boundary values are altered to reflect the level of functional significance.
Claims19
A method executable by a processor for determining if a control button on a touch screen controller (TSC) was inadvertently touched, comprising:
- generating a gaze boundary for the control button that is (1) specific to the control button and (2) independent of a user's gaze point;
- determining the user gaze point;
- determining if the gaze point is within the gaze boundary;
- identifying the level of functional significance of the control button when the gaze point is within the gaze boundary;
- determining a gaze boundary area defined by the gaze boundary of the control button;
- and
- altering the gaze boundary area to reflect the level of functional significance.
A system for determining if a user has inadvertently touched a control button of a touch screen controller, comprising:
- a gaze detection system that detects the user's gaze point;
- a control button identifier coupled to the gaze detecting system;
- a button significance look-up table coupled to the control button identifier;
- and
- a processor coupled to the gaze detection system, the control button identifier, and to the button significance look-up table, and configured to (1) generate a gaze boundary for the control button that is (i) specific to the control button and (ii) independent of a user's gaze point, (2) determine if the gaze point is within the gaze boundary, (3) identify the level of significance of the control button, and (4) alter an area bounded by the gaze boundary to reflect the level of functional significance of the button.
A method executable by a processor for determining if a control button on a touch screen controller (TSC) was inadvertently touched, comprising:
- generating a gaze boundary surrounding the control button that is (1) specific to the control button and (2) independent of a user's gaze point;
- determining the user gaze point;
- determining if the gaze point is within the gaze boundary;
- identifying the level of functional significance of the control button;
- determining a gaze boundary area defined by the gaze boundary of the control button;
- altering the gaze boundary area to reflect the level of functional significance;
- and
- creating an enabling signal if the gaze point is within the gaze boundary area.
