This article has been making the rounds lately in UX circles. Basically it argues that any touchscreen imaginable, no matter how fine the screen, no matter how snappy the performance, will always lack the tactile feedback of handling real objects. We humans interact with objects using our hands. Sliding our fingers along glass screens does not allow us to grip, press, squeeze, or handle anything in the way our hands are designed to do.
I agree. But I also recognize that touchscreens are here to stay. They’re, forgive the term, handy.
