TRANSMISSION AND RECEPTION OF HANDWRITTEN DATA ON WIRELESS DEVICES WITHOUT CHARACTER RECOGNITION
First Claim
1. A method for transmitting a plurality of characters from a mobile device, the method comprising:
- receiving user input to the mobile device, wherein the user input comprises handwritten text having one or more characters;
storing data in a memory of the mobile device based on the user input, wherein the data corresponds to an image of the handwritten text;
compressing the data to produce compressed data; and
transmitting the compressed data to a remote device in a wireless fashion, wherein the compressed data is useable to create the image of the handwritten text on the remote device.

Abstract
A mobile device and associated method for transmitting a plurality of characters to a remote device without requiring keypad input or character recognition. The device is operable to receive characters entered by the user via handwritten input and transmit the characters without requiring character recognition. User input is received to a screen of the wireless handheld device, wherein the user input comprises handwritten text having a plurality of characters, e.g., in a non-Latin character set. Data corresponding to an image of the handwritten text may be compressed, packaged, and transmitted to a remote device in a wireless fashion. The compressed data is useable to create the image of the handwritten text on the remote device. The method preferably does not perform any character recognition on the handwritten text.
