TechFest is upon us so let the brilliant minds at MS Research (Global) share their latest inventions. "Write in the Air" is a proof-of-concept demo for recognizing characters written in the air. In order to input characters into devices such as the Xbox 360 and televisions equipped with a low-cost webcam but no keyboard or mouse, one can just face the camera and write the intended character in the air. The gestures captured by the camera will be fed into a robust handwriting recognizer. Take a look into the future!
