FlickInk is a gesture-sensing pen to support collaborative work and to augment the environment. With a quick "flick" of the pen toward a desired destination, analog written content on paper instantly transfers onto the corresponding physical object in the environment. The FlickInk gesture sensing module allows for wireless communication and directional gesture sensing. If multiple surfaces are present, the direction of the pen swing determines which screen the information is transferred to. Furthermore, multiple users can flick their written content to multiple devices, creating a personalized collaborative environment.
