User centered development of a smart phone mobile application delivering personalized real time advice on sun protection
ABSTRACTSmart phones are changing health communication for Americans. User centered production of a mobile application for sun protection is reported. Focus groups (n 16 adults) provided input on the mobile application concept. Four rounds of usability testing were conducted with 22 adults to develop the interface. An iterative programming procedure moved from a specification document to the final mobile application, named Solar Cell. Adults desired a variety of sun protection advice, identified few barriers to use and were willing to input personal data. The Solar Cell prototype was improved from round 1 (seven of 12 tasks completed) to round 2 (11 of 12 task completed) of usability testing and was interoperable across handsets and networks. The fully produced version was revised during testing. Adults rated Solar Cell as highly user friendly (mean 5.06) The user centered process produced a mobile application that should help many adults manage sun safety.
