Nowadays, it is easy to forget that not every surface is equipped with touch technology, but that might all change thanks to the Magic Finger. The Magic Finger is an accessory that effectively attaches a small micro camera and optical flow sensor to people's index finger. It is able to distinguish between 22 different textures such as desks, pieces of paper or even skin, can recognize 2D data matrix codes and boasts a pinch function that can be programmed to trigger computer commands. It can also be used for data transfers between Magic Finger units.
The Magic Finger was developed by Autodesk Research, the University of Alberta and the University of Toronto. It has an accuracy of 98.9 percent.
