Usability in m-health applications for application in healthcare environments

Mobile devices have become quite popular over the past few years and as a result, the number of applications for the most diverse functions are available for download, many of them free of charge. However, this range of applications does not follow minimum usability parameters, which results in a high level of rejection by users. Within this mobile world, the insertion of devices that aid the health processes, called m-health, has shown an exponential growth in recent years and with this, the warning signal about the efficiency and security of information has been triggered. To remedy this weakness, the introduction of usability techniques during the application development process appears as crucial for minimizing the problem. Numerous studies cite the need for usability in m-health applications, but none of them points out how to obtain it. In this way, this work aims to verify if the design guidelines provided by the Google / Android platform, which is presented as a contribution to mobile software developers, presents guidelines that make it possible to obtain the maximum usability of these applications, considering the proposed user profile and the context of use involved. To this end, the proposal will be based on the comparison between the guidelines contained in the ISO standard (9241) and in consultation with the style guide of the platform called material design.
