Abstract
This paper presents a novel technique for the mobile TUI system which consists of a pico projector and a camera only. The proposed system can transform an arbitrary flat surface into a touch panel. It allows user to interact with a computer by hand gestures on any flat surface in anytime and anyplace. The contributions of the proposed system include the extraction of display screen from the live captured image by a RGB-based camera, shadow-based fingertips detection approach and a fast yet reliable FSM grammar to determine user’s finger gesture. At the end, a prototype system is built to validate the proposed techniques and an experiment is shown in the last.
