Abstract:
The increasing usage of smartphones has resulted in mobile applications
replacing or supplementing traditional web-based applications. Given the limitations
of the form factor in smartphones, usability can be considered one of the important
attributes that determine the success of a mobile application. Many of these
applications suffer from usability issues. Usability concerns user experience,
satisfaction, and perceptiveness.E-payment applications have barriers that make
adoption of the application difficult for emergent users. If these barriers are crossed,
many untapped users are waiting to use mobile payment applications.
We conducted a small review of mobile usability models and found that
usability is usually measured in terms of three attributes; effectiveness, efficiency, and
satisfaction. Other attributes, such as memorability, tend to be overlooked in the
usability models that are most prominent despite their likely impact on the success or
failure of an application
This research aims to review existing usability studies and subsequently
propose a usability framework for the evaluation of the usability of Ocash apps, None
of the attributes that it includes are new, but the existing prominent usability models
ignore one or more of them
The research uses the TAM model to evaluate the usability of the Ocash app.
The framework serves as the basis for comprehensive usability evaluation consisting
of guidelines, usability characteristics, and matrices.
