IR multitouch
Rob Nero, one of the MA in Interaction Design at the School of Arts and Communication, Malmö University, had the idea of using laser beams and IR sensors to develop a flat multitouch surface. It has some drawbacks, but it is 100% Arduino made, using breadboards, resistors, IR transistors, 4051 multiplex ICs, one Arduino Mini and the USB-Serial converter … 100% genuine prototype.
He is making a great collection of videos showing the functionality of it. Here one example, visit his Vimeo profile for more!
