When it comes to ubiquitous computing, a most natural pointing device is gaze to control the cursor movements. There are some obvious problems related in this like involuntary blinking, ruling out double clicks, rightclicks. Moreover resolution in the movements is tough to improve upon. The solution should be non-intrusive and truly transparent in interaction. The proposed solution is contact lens that is detectable from a motion/ position sensor attached to the four corners of glasses (Lets say IR is kept closely focused on the pupil to capture the movements in the X-Y direction) to ultimately result into the cursor movements.

Non-Contact type gaze based cursor control

Non-contact kind solution is best suited as it eliminates a need of carrying something making you truly mobile/ubiquitous. The color of the eyeball across a horizontal plane is used to track the degree of movement in X-Y axes monitored by the cameras at the four corners of spectacles. Each 2 of the 4 cameras focus along either X or Y axis to locate the directrion of gaze. The depth of gaze can be further sensed by monitoring cornea cantraction. The click event can be managed through finger tip wearable sensor rather than a blink as it divides the actions and strikes a balance.
