ABSTRACT:
A communication system and device that enables free-hand drawn SMS (Short Messaging Service) messages to be transmitted and received from/to various user devices. A buffer device is inserted within a GSM compatible handset providing a buffer for both conventional SMS messages created by typing a message on the keypad of the handset and for free-hand drawn SMS messages created by drawing or writing the free-hand message on a data entry device. An optional OCR (Optical Character Recognition) facility can be provided in either the buffer device inserted within the handset or in a network server that receives the transmitted message and processes it for proper routing to the intended recipient.
