+Autonomia – entre o físico e o digital : proposta de design de interação com internet das coisas para apoio à adesão medicamentosa

Abstract

Population aging and the prevalence of chronic diseases have intensified the challenge of low medication adherence and its negative clinical outcomes. In this context, Internet of Things (IoT) technologies emerge as promising tools, although many existing solutions still present accessibility gaps for user groups with different vulnerabilities. This work presents the development and implementation of the “+Autonomia” ecosystem, an integrated solution to support medication adherence composed of a smart organizer box, a mobile application, and a smartwatch interface. The proposal is grounded in User-Centered Design and accessibility principles, utilizing concepts of affordances and signifiers to reduce cognitive load through a visual system that associates colors and icons with times of day. The methodology combined a qualitative investigative stage, based on interviews with health professionals and observation, with agile product development. The technical solution was materialized through the construction of a functional prototype integrating an application developed in React Native and a physical device controlled by an ESP8266 microcontroller, communicating via MQTT protocol to ensure realtime feedback. The results demonstrate the technical feasibility of the proposed IoT architecture, validating the synchronization flow between the physical and digital realms, and establish a roadmap for future work regarding industrial manufacturing and system security enhancement
