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.
