Patent ID: 8577100

Claim:
A remote input method using a fingerprint recognition sensor, comprising the steps of: setting a main device to a fingerprint input mode according to a user's request and displaying a key input unit, menu images and an indicator corresponding to the current fingerprint input mode on a display unit of the main device; generating finger touching data corresponding to the user's duration of touching and number of touches from a remote input device having the fingerprint recognition sensor; generating, at the remote input device, fingerprint pattern data according to a fingerprint image corresponding to the user's finger touched on the fingerprint recognition sensor and coordinate value data of the user's finger; transmitting fingerprint data including the finger touching data, the fingerprint pattern data, and the coordinate value data to the main device through a short range wireless communication module of the remote input device; analyzing the fingerprint pattern data in the main device to determine the type of fingerprint based on previously stored fingerprint information; analyzing a user input pattern based on the determined fingerprint type and the received finger touching data, and performing a preset function corresponding to the user input pattern; and setting, in the main device, a certain function selected by the user corresponding to certain fingerprint data including certain finger touching data and certain fingerprint pattern data according to the user's input through the fingerprint recognition sensor, wherein when the main device is set to a text input mode, the main device displays lines according to the received fingerprint pattern data, thereby displaying a text image and processing the text image as text.
