User Interaction Using Controls

Abstract

Users choose dates, times, text, integers, doubles, and other values on mobile devices by using tactile controls. Touch-sensitive screens have user interaction that differs slightly from mouse-driven UIs: most is done with the thumbs and forefingers on the touchscreen. From the user’s standpoint, this results in a hands-on control-panel interface with switches, icons, sliders, keyboards, and pickers that sometimes look—but more important, feel—like physical mechanisms.
