    摘要: A system and method for locating multiple objects on a capacitive touch pad is described. The method for determining locations of a plurality of objects contemporaneously interacting with a capacitive touch pad having a sensing region includes generating a first capacitive profile associated with a first object and a second object contemporaneously in the sensing region and determining locations of the first and second objects with respect to the sensing region utilizing the first capacitive profile.
