Distinction system of left and right hands placed on a keyboard of laptop computers

We propose a left-right hand distinction system on the touchpad of a laptop computer. The system uses a mirror and a front-facing camera of the laptop computer to obtain the image around the keyboard and the touchpad. The system distinguishes the left and right of a user's hand by image processing the obtained image. In this paper, we demonstrate that the user can execute different operations while keeping the hands on the home position of the keyboard.
