DESIGN DE INTERFACE PARA IDOSOS: CONTRIBUIÇÕES DA INTERAÇÃO HUMANO-COMPUTADOR PARA A SAÚDE E AUTONOMIA NA TERCEIRA IDADE

Abstract

Population aging, combined with the increasing digitalization of health services, highlights the need for inclusive and accessible digital interfaces. In this context, this article analyzes the contributions of Human-Computer Interaction (HCI) to the design of interfaces capable of promoting health, autonomy, and safety for older adults, integrating principles of User Experience (UX) and User Interface (UI). The objective is to identify interaction barriers faced by this population and to systematize accessibility guidelines applicable to the development of digital systems. The methodology is based on Systematic Review of publications between 2010 and 2025, complemented by qualitative analysis of elements present in websites and digital applications. The results indicate that practices such as enlarged typography, generous click areas, multimodal feedback, and simplified navigation help reduce sensory and cognitive barriers, increasing user safety and autonomy. It is concluded that the systematic integration of HCI, UX, and UI principles is essential to promote digital inclusion and improve the effectiveness of technologies aimed at older adults.
