Usabilidade de protótipo de tecnologia digital educacional para leigos sobre reconhecimento e prevenção de sepse

Abstract

Objective: To analyze the usability of a digital educational technology prototype for laypeople on sepsis recognition and prevention. Method: A descriptive study, with a quantitative approach on application usability evaluation, which took place based on ten heuristics, in which problems related to system-user interaction were sought. The study included 15 professionals in the area of technology and design. The MATcH Checklist validated instrument was used. Data were analyzed using the Statistical Package for the Social Sciences version 20.0. Results: The evaluation revealed adequacy in seven heuristics in total, they were: visibility of the status of the system; correspondence between system and the real world; consistency and standards; recognition instead of remembrance; minimalist aesthetics and design; little human / device interaction; and readability and layout. Violations of usability are seen in the heuristics referring to the user's control and freedom; flexibility and efficiency of use; physical interaction and ergonomics, respectively. Conclusion: The usability analysis made it possible to reach possible weaknesses in the Quick Guide Sepsis application and favored the improvement of the software quality.
