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,
particularly to any accessibility lists you may be onWednesday 17th June -
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.

David often seems to be on telly and in the media at the moment talking
about the topic of his excellent free book Sustainable Energy - without the
hot air <http://www.withouthotair.com/>. Here's an excellent video related
to the book called How Many

This is a chance to hear him talk about some other cool stuff he has done in
the field of Human-Computer Interaction and Accessibility. You can expect an
unusual and thought provoking talk.

note that Cambridge is just 45 minutes from Kings Cross but you will need to
get a taxi to get to Microsoft Research, or pack a Brompton).

*Registration:* The event is FREE and you do not need to be a UK UPA member
to attend. Please use the Eventbrite

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.

(you can get an introduction to Dasher and Nomon on the Inference Group's
new Videos web page <http://www.inference.phy.cam.ac.uk/is/videos/>.
