Patent ID: 8536882

Claim:
A device for position detection, comprising: a sensor including a plurality of conductive stripes constituting a plurality of intersecting regions, wherein a pair of depressed conductive stripes intersected in a intersecting region form a contact point and a depressed intersecting region due to electrical contact; a driver for providing a high potential and a low potential; a detector for detecting a signal of at least one conductive stripe; a selector for operatively coupling the conductive stripes with the driver and the detector; and a controller for controlling the driver, the detector and the selector to perform at least the following operations: sequentially selecting one of the conductive stripes as a selected conductive stripe; providing one of the high potential and the low potential to a first end of the selected conductive stripe, and providing the other one of the high potential and the low potential to a first end of a conductive stripe that intersects with the selected conductive stripe; detecting the potential at a second end of at least one conductive stripe in the conductive stripes provided with the high and low potentials; and determining one or both of the depressed conductive stripes and the depressed intersecting region by determining whether one or more conducting paths due to the electrical contact between the pair of depressed conductive stripes are formed based on the potential at the second end of the at least one conductive stripe.
