Apparatus and method for recognizing motion

Abstract

Provided is an apparatus and method of recognizing a motion that is capable of performing a pointing function and a character input function using motions sensed by an optical sensor and an inertial sensor. The apparatus includes an inertial sensor sensing a first motion by using at least one of acceleration and angular velocity that are generated by an input motion; an optical sensor sensing a second motion by using reflection of light due to the motion; a locus calculating unit calculating the locus of the motion on the basis of the locus of the first motion and the locus of the second motion; and a communication unit transmitting the calculated locus of the motion.

What is claimed is: 
     
         1 . A pointer control apparatus comprising:
 a receiving unit receiving at least one of a first motion sensed by an inertial sensor and a second motion sensed by an optical sensor; and   a locus calculating unit calculating the locus of the first motion or applying the locus of the second motion to the locus of the first motion to calculate the locus of the first motion whose error is compensated.
