In this paper we will introduce a new method for making optical multi‐touch devices. The method is called Planar Scatter Detection and has been prototyped in a 32″ format. The technology is viable for all display sizes ranging from a few inches to over 100″. The advantages with this technology are low cost and good size scalability while maintaining multi‐touch performance.
