TWO-DIMENSIONAL AND THREE-DIMENSIONAL LOCATION INFORMATION INPUT DEVICE USING ACCELEROMETER

摘要

PURPOSE: Two-dimensional and three-dimensional location information input device using an accelerometer is provided to measure location by using an accelerometer, thereby completely transmitting the signal without contacting a pad or a plane and exactly controlling the pointing device even in an airplane or a moving vehicle. CONSTITUTION: In a pointing device having one or more click button for transmitting command, wherein two-dimensional and three-dimensional location information input device using an accelerometer includes an accelerometer module(11) for three-dimensional location information, a CPU(12) calculating the duty ratio generated during movement, a control switch(13) setting a basic location in the space, and a right switch and a left switch(6,7) playing a role of a general mouse.
