1-inch UniTouch System using Kinect

Multi-touch system is based on touch technology that utilizes touch sensing as an input. It existed ubiquitously in our daily life such as on smartphones or different types of portable devices. However, current touch systems suffer from many limitations. In this paper, we propose a new large surface multi-touch system, named as “1-inch UniTouch System”. Our solution uses only a single Kinect camera, which is easy to setup and has low entry cost. We also utilize several essential image-processing techniques to improve the system robustness and accuracy. Our prototype system shows that the touch sensing is very robust and works flawlessly even on non-flat surface. Our solution can effectively overcome several limitations existed in previous systems. The outcome of our research shows great potential and we hope to further explore new possibilities with this touch system.
