Avaliação de Interface em Aplicativo para Medição de Nível de Atividade Física Baseado no IPAQ da OMS

Due to globalization and digitalization, there has been a huge increasein the number of mobile applications being developed. Thismakes the user experience and usability of apps a topic of interest.This study evaluates an app based on the World Health Organization’sInternational Physical Activity Questionnaire using JakobNielsen’s heuristics as a framework, aiming to evaluate the finalusers perception of usability. The following ten criteria were considered:visibility of system statuses; correspondence between thereal world and the system; user control and freedom; consistencyand standards; error prevention; recognition rather than recall;flexibility, and efficiency of use; aesthetic and minimalist design;helping users to recognize, diagnose, and recover from errors; andfinally, help and documentation. Therefore, the metology used inthis article made possible to evaluate the system - a scientific iniciation’sproduct - using Nielsen’s heurístics as a baseline of study.In conclusion, this article makes recommendations for changesto the system en route to improve its usability as well the usedmetodology itself.
