Watch-Top Text-Entry: Can Phone-Style Predictive Text-Entry Work with Only 5 Buttons?

This paper presents an initial study into the viability of text entry on a watch face using four alphabetic buttons and a central space key. The study includes a technical evaluation of likely error rates using a large text corpus and user studies on palmtop emulated mobile phone and watch. The results, though in favour of the phone pad, are encouraging and show such a method is feasible.
