As mentioned, the CHI report is being continued…
Mobile Devices, Touchscreens and Maps
iPhone, HTC and other mobile touch devices brought up a strong, fresh trend. The user experience seems to be new and a bit unusual, so I’m pretty sure we will see a lot of upcoming applications, which of course also need their own interaction design.
Escape: A Target Selection Technique Using Visually-cued Gestures
This is a nice solution to reach several targets on a small mobile device using “thumb-gestures”. The question that came up was how can we display more informations concerning these (huge amount of) targets. (And would I display so much targets at all ?!)
For me it came out very clear that the challenge of multitouch used by more than one user is not the technology itself but much more the behavior between different users. We saw a great video of a (really huge) touchable wide screen placed in the city of Helsinki, were people could interact with. Besides “How can people interact together on these screens” of course the question came up, “Which kind of applications are useful in such an environment?” Quite interesting.
