Dasher is an interface for text entry driven by natural continuous pointing gestures, based on information theory.
We recommend looking at the Dasher website, www.inference.phy.cam.ac.uk/dasher for explanation & video.
To install: enable Dasher in System settings -> Language & Keyboard, then long-press on a text field and choose "Input Method". (See www.inference.phy.cam.ac.uk/dasher/MobileDasher.html .)
Dasher development was funded by the EU AEGIS project www.aegis-project.eu
