Andy Cockburn, A. Siresena · UC Research Repository (University of Canterbury) · 2003
This paper describes the evaluation of a new keyboard interface for mobile devices. The Fastap keypad is designed to allow one character per key-press input on mobile devices without requiring additional hardware (such as a plug-in keyboard) or a stylus-based input display. Results of the evaluation show that Fastap is both efficient and rapidly learnable when compared with the current industry standard methods for text messaging.
