What is Plug&touch: a Mobile Interaction Solution for Large Display via Vision-based Hand Gesture Detection about?

Smart phones and external large displays are a superior combination for content sharing and multiple person interaction. However, the potential of such a combination is not fully explored due to the lack of effective and portable interaction solutions. To solve this problem, we present a novel mobile solution called Plug&Touch, which is very easy to be set up and enables mobile users to directly and naturally operate on the large display surface. Plug&Touch utilizes visionbased methods to detect the user's finger tip and then control user interface. The Local Binary Pattern asymmetric texture difference is proposed to extract the foreground region, and the coarse-to-fine intersection process is adopted to precisely localize the finger tip. Plug&Touch has been implemented on the Symbianˆ3 platform with two defined gestures -click and scroll. Experimental results and user evaluation has shown the practicability of Plug&Touch.
