Inclusão digital de idosos: utilização de elementos visuais do design de interface no desenvolvimento de aplicativo mobile para auxílio em compras de supermercado

Abstract

This research’s objective was to evaluate the visual elements of the interface Design for the development of a mobile app that aids in supermarket purchases, aiming to improve the process of digital inclusion of the elderly public. Digital apps may become an important gateway for the elder to access the virtual world and enjoy the benefits that Information and Communication Technologies (ICT) can provide. Design, as a field of research and development, becomes fundamental in this process of promotion and digital inclusion, contributing to the development of suitable products that correspond to the needs of those individuals. The approach adopted in this research was of mixed nature, bearing in mind the acquisition of qualitative and quantitative data for the analysis and formulation of inferences. This research’s method is Design Science Research, being that it is adequate for developing research projects that focus on creating artifacts that promote improvements in the real world and is applied based on the contributions of Pimentel et al. (2020), Santos (2018) and Lacerda et al. (2013). In addition to the collection of bibliographic information, evaluations were carried out with similar products to contribute to the understanding of the problem. Subsequently, a prototype was developed and submitted to a diagnostical usability test, using as collection instruments: pre-test survey, observation, annotations, auxiliary file, and semi-structured interview. The results obtained were satisfactory in terms of the interactional efficacy of the participants with the prototype and of the adequacy of the visual elements applied, as well as it was possible to ratify the conjectures collected in the study. Finally, is hereby ratified a need for effective digital inclusion of the elderly through the expansion of accessible mechanisms and products that contribute to the learning of that public.
