As touch screen technology improves in functionality and decreases in price, these input devices are becoming much more prevalent. People are increasingly required to interact with touch screens at places ranging from their local grocery stores to airport check-in kiosks. Since it is becoming necessary for people to use touch screens in order to access needed products or services, we conducted an experiment to examine how individuals with varying motor control disabilities perform on a simple number entry task. We feel this research is important because, to date, most of the usability research related to touch screens has only included young, healthy subjects.
