Abstract
A user interface technique using a two-dimensional capacitive sensor is provided. An apparatus for sensing movement of multi-touch points includes a capacitance sensing unit sensing two or more touch points, and sensing capacitance and a change in capacitance on the basis of the sensed touch points, a movement analyzing unit sensing and analyzing a change of movement of the two or more touch points using information on the sensed capacitance and change in capacitance, and a command processing unit processing a command corresponding to the change in movement according to a result of the analysis.
