In May I'll be giving a 30-minute presentation at UPA 2010 about evaluating (touch) gesture usability. It'll be based somewhat on material that I posted here previously — part 1, part 2. If you're interested in this topic, I'd be grateful if you'd take a minute and send me your thoughts on what you'd like to see in such a presentation. What would be most useful? What questions do you have about evaluating gestures? I'll do my best to incorporate any suggestions. Thanks.
