touch screen programming

[lifeworks]

Ive been asked to do some work for a client and he wants to use a touch screen. I'd like to know if anyone knows if there are limitations to functionality that a touch screen may impose...?

Thanks

Touch screen and multi touch UI have some implications / some guidelines you want to follow. Size of buttons (enough to be pushed with a finger), also consider the free space between each elements to avoid accidents e.g. two buttons pressed at the same time. Someone has suggested an effective navigation too, preferably locating a group of buttons into one region, making the UI usability very similar to PDA, mobile phones or kiosks.
