Developing Usability Guidelines for mHealth Applications (UGmHA)

Mobile health (mHealth) is a branch of electronic health (eHealth) technology that provides healthcare services using smartphones and wearable devices. However, most mHealth applications were developed without applying mHealth specialized usability guidelines. Although many researchers have used various guidelines to design and evaluate mHealth applications, these guidelines have certain limitations. First, some of them are general guidelines. Second, others are specified for mHealth applications; however, they only cover a few features of mHealth applications. Third, some of them did not consider accessibility needs for the elderly and people with special needs. Therefore, this paper proposes a new set of usability guidelines for mHealth applications (UGmHA) based on Quinones et al.’s formal methodology, which consists of seven stages starting from the Exploratory stage and ending with the Refining stage. What distinguishes these proposed guidelines is that they are easy to follow, consider the feature of accessibility for the elderly and people with special needs and cover different features of mHealth applications. In order to validate UGmHA, an experiment was conducted on two applications in Saudi Arabia using UGmHA versus other well-known usability guidelines to discover usability issues. The experimental results show that the UGmHA discovered more usability issues than did the other guidelines.
