Abstract
A sensing technique using a capacitance touch sensor as a user interface is provided. An apparatus for sensing the movement of fingers using a multi-touch sensor includes a touch determination module which determines whether a user has actually touched a touch sensor comprising one or more touch points with at least one of his/her fingers, a clustering module which groups a plurality of electrodes arrayed in the touch sensor into one or more clusters according to a set of standards if the touch determination module determines that the user has actually touched the touch sensor with at least one of his/her finger, a position value calculation module which calculates a finger position value indicating the location of the finger of the user that touches the touch sensor for each of the clusters, and a movement information detection module which detects movement information of the finger of the user that touches the touch sensor using information regarding variations over time in the finger position value.
