| dc.description.abstract | We present a flexible system to track the movements of a bare finger on a flat surface. The proposed system is able to discriminate whether the user is touching or just pointing at the surface. The system works using two webcams and a fast scanline-based algorithm. The initial setup of the two webcams is easy and fast. No markers, gloves, or other hand-held devices are required. Since the system is independent from the nature of the pointing surface, it is possible to use a screen or a projected wall as a virtual touchscreen. The complexity of the algorithms used by the system grows less than linearly with resolution, making the software layer very lightweight and suitable also for low-powered devices like embedded controllers. | en_US |
