A Quality Assessment Model Based on Usability Metrics for M-Health Applications User Interfaces

Mobile health (m-Health) applications are gaining popularity for the past few decades. The user interfaces of such applications must be usable and comfortable enough so that they can meet the expectations of their indented users (i.e. doctors, patients etc.). Usability is considered to be one of the key quality factors for measuring the usefulness of such applications which makes usability evaluation a vital task. In this paper, we propose a quality assessment model for evaluating the user interfaces of m-Health applications by reviewing the existing literature and frameworks on the evaluation of user interface designs. The proposed assessment model serves as a base for a comprehensive usability evaluation consisting of major usability goals, subfactors, and metrics. The effectiveness and reliability of the proposed model is measured through two android m-health applications. The results gathered from usability testing and statistical techniques validated that the model is applicable for the evaluation of the m-Health applications and act as a helping tool for evaluators and user interface designers.
