PuffText

The purpose of this prototype is to demonstrate a use of puff input for text entry. The entry method is based on hierarchical scanninglike selection of characters located in a static table organized according too the letter frequency. The cursor is moved in a way similar to operating a claw crane machine with two buttons. To move the cursor to the target position the user needs to produce two puffs, the first selects the column, and the second selects the row.With a brief training the method is capable of entry rate of 5 WPM.

This work proposes progresses on the use of a breathing based text input software for mobile 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 dynamically generated 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 entry through "puffing" interaction.
