ABSTRACT:
A method of detecting and interpreting a path of designated positions is disclosed. The method concurrently detects a plurality of designated positions on a touch panel, again detects the plurality of designated positions subsequent to a travel of the designated positions, determines the distances between each of the current designated positions and the respective immediately preceding designated positions, treats an immediately preceding designated position, closest to the current designated position of interest, as the immediately preceding designated position of the current designated position of interest, and acquires the path of each designated position, thereby recognizing the paths of the plurality of designated positions that move concurrently. A combination of the paths of the plurality of designated positions is interpreted to identify a designation input by a user, and an operation thus designated is executed.
