isiQiri: Interface Technology
isiQiri´s proprietary Q-Foil-technology is a new sensor technology that can be used to detect light spots or shadows on large surface areas. Our products can be used to add interactivity to all kinds of surfaces like projection screens, walls, shop windows, light curtains, furniture, clothing and even whole rooms. Based on an advanced coupling of modern opto-electronic devices with a high-tech plastic foil comprising optically active molecules, the Q-Foil-technology yields a flexible optical sensor. Less than a millimeter in thickness and bendable, a Q-Foil can pinpoint and trace the location of a light spot hitting its surface with high accuracy.
