  Health-related mobile applications are known as eHealth apps. These apps make
people more aware of their health, help during critical situations, provide
home-based disease management, and monitor/support personalized care through
sensing/interaction. eHealth app usage is rapidly increasing with a large
number of new apps being developed. Unfortunately, many eHealth apps do not
successfully adopt Human-Centric Issues (HCI) in the app development process
and its deployment stages, leading them to become ineffective and not inclusive
of diverse end-users. This paper provides an initial assessment of key human
factors related to eHealth apps by literature review, existing guidelines
analysis, and user studies. Preliminary results suggest that Usability,
Accessibility, Reliability, Versatility, and User Experience are essential HCIs
for eHealth apps, and need further attention from researchers and
practitioners. Therefore, outcomes of this research will look to amend support
for users, developers, and stakeholders of eHealth apps in the form of improved
actionable guidelines, best practice examples, and evaluation techniques. The
research also aims to trial the proposed solutions on real-world projects.
