Abstract
A high dimensional touchpad (HDTP) controls a variety of computer windows systems and applications by detecting a user's finger movement in the left-right, forward-backward, roll, pitch, yaw, and downward pressure directions. Measurements obtained from the touchpad of at least two attributes of finger movement at two different time intervals are used to provide a first and a second finger position attribute used to control an application on an electronic device. The finger roll angle is determined by detecting the edge and the peak region of a finger contact area. Also, a visual color displayed in an application operating on an electronic device is controlled by a measured-angle value of a finger in contact with a touchpad.
