HD Touch: Multi-touch and Object Sensing on a High Definition LCD TV

摘要

In this paper, we describe our first prototype in implementing a robust and low-cost multi-touch and tangible system using a High Definition LCD monitor. Since our prototype utilizes an LCD, we discuss and compare the advantages that HD LCD monitors provide over projectors. Secondly, we give an overview of the sensing data the system can detect, and what interaction techniques it enables. Since our approach is scalable, we anticipate being able to implement multi-touch and tangible interactions on large high-definition LCD monitors in the future.
