πŸ“Œ Abstract

Air-writing systems render a form of gestural human-computer interaction. Such systems are especially useful for building advanced user interfaces that do not require traditional mechanisms of linguistic input, such as pen-up-pen-down motion, hardware input devices, or virtual keyboards. On the contrary, these advanced systems provide an interface for writing through hand gestures in three-dimensional space with six degrees of freedom. 

The input scheme in such systems fundamentally differs from a generic pen-up-pen-down input mechanism because, in the case of the former, there is no robust way of defining start (pen-down) and stop (pen-up) states while writing. 

Unlike conventional writing, air-writing systems lack actual anchoring and reference positions on the writing plane. Gestures are guided by considering imaginary axes in three-dimensional space. Consequently, these facts contribute to the increased variability of writing patterns for such systems, thereby accounting for the non-trivial nature of the problem. This talk includes a discussion on several techniques for air writing recognition and demonstration.
