Abstract: A system and methods are provided to manage gestures and positional data from a pointing device, considering an attention sensing device with known accuracy characteristics. The method uses the state of the user's attention and the pointing device data as input, mapping them against predefined regions on the device's screen(s). It then uses both the mapping results and raw inputs to affect the device, such as sending instructions or moving the pointing cursor.

Abstract: A system and method are provided for performing eye gaze tracking. The system is configured for and the method comprises optimizing illumination of a scene for a single on-axis imaging apparatus, capturing an image using the single on-axis imaging apparatus under the optimized illumination, and processing the captured image to perform a gaze estimation. Dynamic illumination control, eye candidate detection and filtering, and gaze estimation techniques are also provided.
