Patent ID: 7460109

Claim:
A device comprising: a mobile embedded device having a cursor manipulator, the cursor manipulator including, a sensing surface operative to sense contact by the human finger, the contact corresponding to applied pressure, a pressure sensor array disposed on the sensing surface, wherein a measurement of the plurality of pressure sensors corresponds to an image, and an image detector, receiving images from the pressure sensor array, generating cursor manipulation corresponding to changes between the images, wherein a sampling resolution of the sensing surface is based on at least one of periodically sampling alternating pixels in the pressure sensor array such that sampled pixels are distributed in a periodic pattern throughout the pressure sensor array and monitoring at least one of a plurality of zones in the pressure sensor array, wherein the plurality of zones are distributed in a non-overlapping pattern throughout the pressure sensor array, and wherein each of the plurality of zones includes multiple pixels of the pressure sensor array, the plurality of zones collectively providing navigation data.
