Typing text messages on a mobile phone via the tiny soft keyboard is very cumbersome. How about simply writing your words in the air? This idea drove the development of “airwriting” developed by computer scientists at the Karlsruhe Institute of Technology in Germany. Sensors attached to a glove record hand movements, a computer system captures relevant signals and translates them into text, which can then create an email, text message, or any other type of mobile app. “Our Airwriting glove fits on the back of the hand. It has motion sensors, accelerometers and angular rate sensors – technologies used in modern smartphones – and signals are just recorded and transmitted via Bluetooth, for example, in this case to a laptop," says computer scientist Christoph Amma.
