Abstract:
A method and the device for position detection are disclosed. The device comprises a plurality of strips intersecting each other to form a plurality of intersecting regions. A pair of depressed strips intersecting on an intersecting region contact to each other to form a depressed intersecting region. According to the depressed intersecting regions, each depression can be determined. The total contact impedance of a depressing crossover a plurality of intersecting regions is the parallel contact impedance of the contact impedances of all intersecting regions corresponding to the same depression.
