Abstract

A system and method for improving accuracy of a hand gesture by sensing eye gaze of a user. The hand gesture is detected by a high resolution motion sensor. The eye gaze represents current focus of the user and accurately identifies intent of the user.

System And Method For Improving Accuracy Of Hand Gesture Detection By Sensing Eye Gaze

Disclosed is a system and method for improving accuracy of a hand gesture by sensing eye gaze of a user. The hand gesture is detected by a high resolution motion sensor. The eye gaze represents current focus of the user and accurately identifies intent of the user.

The main objectives of the invention are elimination of blind spot created by movement of a hand of a user and improving accuracy of target object detection using combination. Both the objectives are achieved by using the combination of hand gesture sensing and eye gaze sensing.

In accordance with the method and system, eye gaze of a user is detected to determine focus of the user as illustrated in the Figure.

objects and the set of blind spots. A set of visual adjustments are made to avoid the set of blind spots. The visual adjustment may include showing a gesture spawned menu at an alternate location to a blind spot. Alternately an evasive visual action may be made to prevent a blind spot. The evasive visual action may include one or more of, but not limited to, moving a target object, and moving a screen of reference.

The hand gesture is used to identify a plurality of target objects. A confidence factor is computed based...
