Desenvolvimento de uma aplicação móvel gamificada com realidade aumentada para apoio da avaliação da literacia nutricional

Abstract

Nutritional literacy plays a key role in the adoption of healthy eating habits, and the development of digital solutions that support its assessment and understanding is becoming increasingly important. At the same time, the growth of mobile technologies and Augmented Reality has created new opportunities for the development of more interactive and engaging digital solutions in the fields of health and education. In this context, this thesis, developed as part of the NUTLY 2.0 project, aimed to design and develop a gamified mobile app using Augmented Reality to support the assessment of nutritional literacy through interactive visual tasks. The study aimed to explore how these technologies can be used to create more intuitive and engaging assessment experiences, contributing to research in this area. The research followed the Design Science Research methodology, complemented by agile development practices based on the Scrum framework. The process included a literature review, an analysis of existing applications, meetings with stakeholders from the NUTLY 2.0 project to validate user stories and requirements, the development of a functional prototype in React Native, and its evaluation with users. The evaluation was conducted with fifteen participants, using a questionnaire and the Think Aloud method to collect data on the user experience and perception of the application. The results obtained allowed for an analysis of the suitability of the implemented features, gamification elements, and the use of Augmented Reality in the context of nutritional literacy assessment. The study contributes to understanding the potential of these technologies in creating digital assessment tools and provides guidelines that may support the future development of the NUTLY 2.0 project's digital tool.
