Avaliação da usabilidade e experiência de uso no youtube em público da terceira idade: estudo de caso na cidade de Palhano, Ceará

Abstract

The aging of the population is a fact that, together with the growing technological adoption by elderly people, highlights the need to think about policies and solutions that meet the specific demands of this group, including the use of appropriate and accessible technologies. In Human- Computer Interaction (HCI), evaluation methods play a crucial role in determining how effective a system is in meeting users’ needs. These methods provide essential insights into pain points, enabling a targeted approach to fixes and improvements. With this in mind, the present work seeks to investigate the use of the YouTube application in order to identify the main difficulties faced by older users, specifically in the city of Palhano, Ceará. To this end, this study carries out HCI evaluations, focusing on the following criteria: usability, user experience and accessibility, including the use of a set of heuristics aimed at elderly people with a focus on smartphone applications. This study seeks to identify, in practice, the main usability problems, in addition to the needs and preferences of this age group. As a result of this research, certain barriers were identified in the application that impact elderly users, such as the use of jargon and icons, the performance of manual actions, the use of advanced settings and the location of functions considered essential.
