This work proposes the use of a low-cost software-based puff controlled hands-free spinning keyboard for mobile phones as an alternative interaction technology for people with motor disabilities. It attempts to explore the processing of the audio from the microphone in mobile phones to select characters from a spinning keyboard. A proof of concept of this work is demonstrated by the implementation and experimentation of a mobile application prototype that enables users to perform text input through “puffing” interaction.
