	TapSongs: Rhythm-Based Password Entry Devising a user authentication method that uses a single sensor tapped according to a song rhythm. Useful for logging into devices that have no space for keyboards or gestures. [Show 1 publication] Wobbrock, J.O. (2009). TapSongs: Tapping rhythm-based passwords on a single binary sensor.

	EyeWrite Comparing a gestural means of writing with the eyes to traditional eye-typing on an on-screen keyboard. Significantly adapts and extends the EdgeWrite design for text input to the vagaries of eye-tracking. [youtube] [Show 2 publications] Wobbrock, J.O., Rubinstein, J., Sawyer, M.W. and Duchowski, A.T.

	EdgeWrite Making text entry possible on a variety of devices through a simple, versatile, reusable design for letter-like text entry. EdgeWrite was originally designed as an assistive technology for improving text entry on PDAs, but now has versions on trackballs, joysticks, touchpads, sensors, keys, and more. Innovations include continuous recognition feedback, non-recognition retry, slip detection, a four-way scroll ring, and in-stroke word completion. [Visit www.edgewrite.com]
