Dasher - writing with gestures

Just watched a fascinating video of a new gesture-based writing system called Dasher on Google Tech Talks. Dasher is a writing system which uses information theoric concepts to allow the user to steer through an emerging web of possible word completions. Developed at Cambridge University and demonstrated by Dave McKay, Dasher is seen as a tool with immediate applicability for mobile phone users as an alternative to predictive texting and for people with disabilities. However, it seems to me that with a claimed rate of 35 words per minute, it would be useful alternative to “hunt and peck” typing on a keyboard. It’s difficult to describe, but there’s a Java applet version that you can try on-line. Dasher has been ported to multiple platforms and is freely down-loadable. Worthy of further investigation!
