Touch screens such as those found on the iPhone or iPad are the latest form of technology allowing interaction with smart phones, computers and other devices. However, scientists at Fraunhofer FIT has developed the next generation non-contact gesture and finger recognition system. The novel system detects hand and finger positions in real-time and translates these into appropriate interaction commands. Furthermore, the system does not require special gloves or markers and is capable of supporting multiple users.

With touch screens becoming increasingly popular, classic interaction techniques such as a mouse and keyboard are becoming less frequently used. One example of a breakthrough is the Apple iPhone which was released in summer 2007. Since then many other devices featuring touch screens and similar characteristics have been successfully launched — with more advanced devices even supporting multiple users simultaneously, e.g. the Microsoft Surface table becoming available. This is an entire surface which can be used for input. However, this form of interaction is specifically designed for two-dimensional surfaces.

Fraunhofer FIT has developed the next generation of multi-touch environment, one that requires no physical contact and is entirely gesture-based. This system detects multiple fingers and hands at the same time and allows the user to interact with objects on a display. The users move their hands and fingers in the air and the system automatically recognizes and interprets the gestures accordingly.
