Claim One:
1. A method of recognizing a character finger-traced on a plurality of touch responsive electrodes, comprising: detecting values of touch capacitances of at least two of said touch responsive electrodes which are touched simultaneously by a person's finger; a first step of storing the value of each touch capacitance detected in said detecting step; calculating central contacting point data based on said stored values of the touch capacitances of at least two of said touch responsive electrodes, for thereby obtaining any one of at least three different central contacting point data between at least two of said touch responsive electrodes in addition to actuation of individual electrodes the touch capacitances of which were stored in said first storing step; a second step of storing the central contacting point data obtained in said calculating step; repeating said detecting step, said first storing step, said calculating step and said second storing step while said person's finger is tracing on said plurality of touch responsive electrodes, thereby obtaining plural items of central contacting point data which are greater in number than those of said touch responsive electrodes which are finger-traced; and recognizing a finger-traced character based on said plural items of central contacting point data obtained by said repeating step.
