Usability of mobile applicationsAccording to Rachel Carrison, Derek Flood, and David Duce (2013).The usefulness of mobile devices has increased greatly in recent years allowing users to perform more tasks in a mobile context. This increase in usefulness has come at the expense of the usability of these devices in some contexts.
8e conducted a small review of mobile usability models andfound that usability is usually measured in terms of three attributesHeffectiveness, efficiency and satisfaction. Other attributes, such as cognitive load, tend to be overlooked in the usability models that are most prominent despite their likely impact on the success or failure of an application. To remedy this we introduces the PACMAD (People at the Centre Mobile Application Development) usability model which was designed to address the limitations of existing usability models when applied to mobile devices.
‘A45A7 brings together significant attributes from different usability models in order to create a more comprehensive model. :one of the attributes that it includes are new, but the existing prominent usability models ignore one or more of them. This could lead to an incomplete usability evaluation. We performed a literature search to compile a collection of studies that evaluate mobile applications and then evaluated the studies using our model.
