3D input apparatus and method thereof
First Claim
1. A 3D input apparatus for detecting input information, comprising:
- a sensor package measuring a first velocity, an acceleration, and an angular velocity of the 3D input apparatus in a relative body coordinate system;
a posture information generating unit generating posture information of the 3D input apparatus using the measured acceleration and angular velocity;
a velocity transformation unit transforming the measured first velocity into a second velocity in an absolute coordinate system using the posture information; and
a position restoration unit determining a position of the 3D input apparatus by integrating the second velocity.

Abstract
Provided are a 3D input apparatus and method for precisely detecting a position of the 3D input apparatus. The 3D input apparatus includes a sensor package which measures a first velocity an acceleration, and an angular velocity of the 3D input apparatus in a relative body coordinate system; a posture information generating unit, which generates posture information of the 3D input apparatus using the measured acceleration and angular velocity; a velocity transformation unit, which transforms the measured first velocity into a second velocity in an absolute coordinate system using the posture information; and a position restoration unit, which determines a position of the 3D input apparatus by integrating the second velocity.
