Filed:

Aug 15, 2009

Appl. No.:

12/541948

Inventors:

Steven H. Simon - Oakland CA, US

International Classification:

G06F 3/041

US Classification:

178 1803

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.

Abstract:

A method for detecting roll angles of a finger in contact with a fingerprint scanning sensor is described. The method includes obtaining spatial measurement data of a measurable contact area from a touch surface of a fingerprint scanning sensor, using an algorithm to create at least two statistical quantities from this spatial measurement data, using the statistical quantities to generate at least one measurement of a finger roll angle with respect to a reference position, and providing the roll angle measurement for external uses. This method can also be used to detect pitch angles of a finger contacting a fingerprint scanning sensor. The roll and pitch angles are calculated in real time and used for controlling applications on electronic devices such as computers and mobile phones.
