Abstract
Advances in display and input technologies either based onlectronic devices or computer vision have led to booming popularity of tabletop systems. There is a trend to use larger display with higher resolution, and to manipulate digital content by nature interactions such as direct-touch. In our previous work, we had developed a system called i-m-Top, which''s able to realize an interactive high-resolution display in a cost-effective way by accommodating to human vision. The high-resolution display is achieved by combining one steerable fovea projector and one peripheral projector, and the large-ranged touch-sensing is based on diffused illumination and analyzed by computer vision technology. In this work, we continue to improve the accuracy and efficiency of touch detection. Through observing and experiencing the difficulties encountered in the development process, we further propose a software development toolkit for rapid prototyping multi-resolution and multi-touch applications, to help push forward the research on this kind of systems.
