7 Jun 2009 - 4:12pm
Hi All,Forgive the cross-posting. You are very welcome to come to our
forthcoming event which covers a couple of clever ways to enter text without
a keyboard. David is an excellent speaker and the subject is fascinating
(links below will give you a taster). If you have only access to a single
switch - how can you enter text? Come along and find out.Just 45 minutes
from Kings Cross!See you there.CarlPS Please feel free to forward this on,

Prof. David MacKay - Hands free writing (and more) - Dasher and Nomon
The problem with polymaths is that they are often extremely busy doing
important stuff. We are extremely fortunate that David
a Professor of Natural Philosophy (Physics) at Cambridge University, has
agreed to give us this unusual talk outlining credible and creative tools
for entering text without using a keyboard.
I'll describe a couple of communication systems based on information theory,
both of which allow fast communication with minimal muscle movements.
First, *Dasher* - over ten years old now - uses a navigational metaphor to
embody an idea stolen from data compression, arithmetic coding. Hands-free
writing is possible in any language, using head-tracking, gaze tracking, or
one or two switches.
Second, *Nomon*, created this year by Tamara Broderick, provides a general
way of using a single switch to communicate, which is faster and requires
fewer gestures than standard Grid methods.
