Adaptive interface for text input on large-scale interactive surfaces

In this paper we present a novel approach to text input on large interactive surfaces using a combination of strategies to resolve the inherent difficulties with text input on such a device. Instead of using a conventional full size QWERTY based layout, the idea is to use a very limited set of buttons that, by using word prediction and hints, would only require minimal finger movement. The input mechanism is somewhat related to input methods employed when using keyboards with a limited size and amount of keys, commonly found in phones and other 10 digit keyboards. Given that the main motivation to this approach was not the limited size but rather to overcome the difficult task of locating keys with fingers on a flat and featureless surface, making touchtyping very difficult and requiring frequent visual monitoring of the finger position, we opted to enhance the interaction with easily made gestures, a layout that adapts to the hand anatomy of the user, and easy control over the...
