Developing a motion-based input model for mobile devices

This paper discusses a new input model for camera- equipped mobile devices which is more efficient, intuitive and intelligent. This model takes advantage of the motion captured from the camera: the general movement of both device and user, These movements are mapped to a three-dimension space and input methods are devised depending on the current situational context. Such an interface allows users to far more quickly interact with their devices, avoids navigation though nested menus and allows the device to perform natural tasks without the user having to knowingly interact with it.
