Heuristics-based Responsiveness Evaluation of a Telemedicine Computacional Web System

Abstract

Computational technologies are increasingly included in our lives, presenting themselves as indispensable tools in most human activities and benefiting different areas of knowledge, such as the medical one. The Integrated Telemedicine and Data Management System, developed by our research group, is within this scenario and allows medical procedures to be transmitted and watched remotely in real time. Its initial development was focused on personal computers, but due to the need of providing better experiences with different devices, changes were made in the interface of some of the main features. The idea was to implement responsive design concepts in the system and allow users to access it in mobile devices, such as tablets and smartphones. This article aims to evaluate the system responsiveness by applying a usability script for three devices: notebook, tablet, and smartphone. In particular, ten collaborators completed a questionnaire composed of twelve affirmative heuristics related to the system usability, using the Likert scale of three items and the numerical scale from 0 to 100 to evaluate their level of satisfaction for each heuristic. The results show that the changes performed in the system are functional.
