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.
