U-Sketchbook: Mobile augmented reality system using IR camera

In this paper, we propose the novel interface system for mobile phone using infrared pointer scheme. Our approach exploits mobile augmented reality technology using IR camera. We implemented the proposed mechanism on smartphone and applied the proposed interface to sketchbook application called U-Sketchbook. Users can draw picture on any space available and the IR camera can detect the movement of pointing device (IR-Pen). We performed several experiments to test effectiveness of the proposed system. The experiment result shows that users can easily use U-Sketchbook for multimedia application such as an image editor. The prototype can track IR-Pen within 30ms, which makes users feel very comfortable using the proposed system.
