Pointing apparatus and method
First Claim
1. A pointing apparatus, which inputs a movement signal to a portable computer, the apparatus comprising:
- an accelerometer disposed on a finger and outputting an acceleration signal in response to a motion of the finger; and
a signal processing unit sensing micro-collisions generated when the finger comes into contact with a contact surface and a rising signal generated when the finger is detached from the contact surface, using the acceleration signal, sensing the motion of the finger between a generation of the micro-collisions and a generation of the rising signal, and outputting the movement signal.

Abstract
Provided are a pointing apparatus and method. The apparatus, which inputs a pointing signal to a portable computer, includes an accelerometer outputting an acceleration signal in response to motion of the finger; and a signal processing unit sensing micro-collisions generated when the finger comes into contact with a predetermined contact surface and a rising signal generated when the finger is detached from the contact surface using the acceleration signal, sensing pointing motion of the finger lasting between the generation of the micro-collisions and the generation of the rising signal, and outputting the pointing signal.

16. A method of inputting a movement signal to a portable computer using an apparatus mounted on a finger, the method comprising:
-
receiving an acceleration signal in response to a motion of the finger;
sensing micro-collisions generated when the finger comes into contact with a predetermined contact surface, using the acceleration signal;
sensing a rising signal generated when the finger is detached from the contact surface, using the acceleration signal; and
calculating a direction and a distance in which the finger moves from a moment the micro-collisions occur until the rising signal is sensed. - View Dependent Claims (17, 18)
