We have at least one touch-screen devices. The most major touch screen is used resistive. However, resistive touch screen is not suitable for upsizing. This study proposes touch screen method with two mirrors and one camera. By using mirrors, we calculate the coordinates of the finger on one camera by triangulation. Experiments were performed to confirm the proposed method. We confirmed the effectiveness of the proposed method by the experiment results.
