PURPOSE: A 3D mouse and a system with the same is provided to predict an X/Y-axial rotation angle and a Z-axial direction moving distance of the mouse by a value measured by a distance sensor, thereby providing quick response speed and high accuracy. CONSTITUTION: A reference frame(100) comprises at least three distance sensors. A reflection frame(200) moves about the reference frame. The distance sensors measure the distance between the reflection frame and the reference frame. An operation processing unit operates X/Y-axial rotation angles of a 3D mouse based on the measured distance. At least one distance sensor measures the distance between the reference frame and the reflection frame based on illumination of reflected light after irradiating light toward the reflection frame. |
