Comparison of Usability of PC Based and Smartphone Symptom Checker
Computerized symptom checkers are becoming increasingly popular, however, although they have been tested for accuracy there is little information around the usability and perceived usefulness of computer-based symptom checkers. Previous work has shown that elderly users prefer to use larger format devices. This study concentrated on the differences between smartphone and PC-based systems. This research compared four symptom checkers (two PC based: Isabel, Symcat and two smartphones based: Ada, WebMD) using a think-aloud usability evaluation protocol and a questionnaire based on the technology acceptance model (TAM).
