In this paper, we propose a pointing method using gesture input with two accelerometers. By dividing motion operation of two coordinates into the combination of two motions, we aim to raise the accuracy of the pointing. In our proposing technique, a user installs two small accelerometers on both hands or both elbows. Movement of two straight lines on the screen is synchronized with movement of accelerometers and pointing is done by using the intersection of two straight lines. These accelerometers can be attached on two elbows, hands, and knees of a user, which achieves hands free pointing.
