PORTABLE TELEPHONE HANDSET STRUCTURE WITH INTEGRATED HANDWRITING INPUT SURFACE

摘要

PROBLEM TO BE SOLVED: To enable a user to input not only numbers, but also alphabet letters without using an ordinary push-button key pad by including a handwriting input surface where a telephone number to be dialed can be inputted by tracing the respective numbers. SOLUTION: Instead of touching an LCD screen to input a telephone number, the user is able to input the telephone number, letter by letter by 'writing' the respective numbers on the handwriting surface 35 with a finger or stylus. The handwriting input surface 35 operates in combination with handwritten character recognition software stored in the electronic device of the main body part 13 of the telephone. This software interprets the movement when the path corresponding to the characters, numbers, or symbols on the handwriting input surface 35 is traced with the stylus or finger of the user and operates to input, for example, alphanumeric data or executes a specific command for redialing.
