Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An input device operable in both a pointing mode and a writing mode, the input device comprising: a motion sensor for detecting a first motion of the input device in the pointing mode and in the writing mode; an optical sensor for detecting a second motion of the input device in the writing mode by detecting light reflected directly from an external object surface; a communication unit for communicating with an external display device; and a controller…
