Disclosed is a remote input method using a fingerprint recognition sensor. A main device activates a fingerprint input mode according to a user's request, and displays a key input unit, menu images and an indicator corresponding to the fingerprint input mode. A remote input device having the fingerprint recognition sensor generates fingerprint data corresponding to the finger touching method in real time, and sends the generated fingerprint data to the main device through a short range wireless communication module. When receiving the fingerprint data, the main device analyzes the type of fingerprint included in the fingerprint data based on the previously stored fingerprint information. The main device also analyzes the user input pattern according to the type of fingerprint and the fingerprint data reception type. Consequently, the main device implements a preset function corresponding to the analyzed user input pattern. The user can control various functions available in the main device using the remote input unit.

Remote input method using fingerprint recognition sensor

A method and apparatus for providing an instrument playing service in a portable terminal. In the method, an image of an instrument is projected. User finger movements on the projected instrument image are detected and sound source information corresponding to the user finger movements is read. Thereafter, an audio signal corresponding to the sound source information is output.
