Type in Air for a Computer...!!!

Writing Without Keyboard: Handwriting Recognition On the Wrist

Typing text messages on the mobile phone via the tiny soft keyboard is very cumbersome. How about simply writing it into the air! This idea drove the development of "airwriting" made by computer scientists of Karlsruhe Institute of Technology (KIT). Sensors attached to a glove record hand movements, a computer system captures relevant signals and translates them into text.

The system offers a new interface for wearable computing applications. These are computer systems worn like clothes, which can be integrated seamlessly into the everyday life of the user. "Information technology is used any time and anywhere, but smart phones are still working on the basis of virtual keyboards and small screens. However, gestures allow for new types of input -- in particular for mobile devices or devices integrated in clothing. The interaction is embedded seamlessly in everyday life".

"The airwriting glove is used to write letters into air, as if using an invisible board or pad."
For this purpose, acceleration sensors and gyroscopes are attached to the thin glove. Contrary to systems based on cameras, these sensors are very small, mobile, and robust. They record the movements of the hand and transmit them to a computer system via a wireless connection. The computer system first checks whether the user is indeed writing.
