Anyone familiar with other touchscreen examples that are somewhere
in-between your typical Walgreens kiosk and Jeff Han's multitouch demo (in
terms of complexity)? There was a nice IxDA thread about this a few years
ago, but I'm looking for more recent projects.
I know this must have gone around and I just missed it somehow.
"Jeff Han demonstrates—for the first time publicly—his intuitive,
"interface-free," touch-driven computer screen, which can be
manipulated intuitively with the fingertips, and responds to varying
levels of pressure."
It's been a while since I've designed a touch screen interface, so... given a 15" LCD display and finger for stylus, what's the general consensus for the size of a discreet target? In the olden days on a CRT, it was typically about 20mm or 3/4". Given the reduction in paralax, improvements in touchscreen technologies, and such, what is a "standard" target size?
I'm working on a touchscreen UI application at the moment, and as many
of you know, such interfaces present pretty interesting challenges.
This project is especially interesting in its complexity; it deals with
pretty vertical domain knowledge and its users need extremely flexible
and freeform methods of interaction with the kiosk...tons of buttons,
which certainly creates rather interesting issues of screen real estate
at 1024x768. ;-)
Naturally, this had made me very aware of touchscreen UI's I've used
