Abstract

The LampTop enables an effective low cost touch interface utilizing only a single camera and a pico projector. It embeds a small shape in the image generated by the user application (e.g. a touch screen menu with icons) and detects touch by measuring the geometrical distortion in the camera captured image. Fourier shape descriptors are extracted from the camera-captured image to obtain an estimate of the shape distortion. The touch event is detected using a Support Vector Machine. Quantitative results show that the proposed method can effectively detect touch.
