Abstract :
Recent years, we have at least one touch-screen devices. The major types of touch screen are resistive touch screen. However, resistive touch screen is not suitable for up-sizing. This study proposes a touch screen method with two mirrors and one camera. By using the two mirrors and one camera, we can calculate the coordinates of a finger touched on the screen by triangulation. We did some measurement experiments to confirm our proposed method. The effectiveness of the proposed method was confirmed by the experiment results.
