- Assessment of activity trackers: toward an acceptance modelPublication . Sol, Ricardo; Baras, KarolinaIn this project we seek to understand the factors that influence user acceptance of Activity Trackers, through a model that quantifies how users come to adhere to the use of Activity Trackers. The proposed research model and hypotheses were validated and tested with data collected from a cross-sectional survey conducted using a self-selected convenience sample. Constructs from half dozen of established models were gathered into a suppositional model, based on their hypothetical applicable relevance for the Activity Trackers use. The results were analyzed using a variety of statistical techniques including Structural Equation analysis. The final result can be a first step for researchers aiming to complement their own processes of study, ideation or design of Activity by taking into account factors such as Usefulness, Ease of Use, Health Consciousness, Hedonic Motivation, Image, Habit, etc.
- Acceptance model in designing for extreme users: extreme athletes using activity trackersPublication . Sol, Ricardo; Baras, Karolina‘Extreme Users’ (EU) is a design method in Human Computer Interaction, which allows user-centered design in design groups. ‘Acceptance Models’ is a theory in Information Systems, which models how users accept and use technology. We conducted a study to explore the relationships of the factors influencing Extreme Athletes in the acceptance and use of Activity Trackers (AT). The data was collected from a cross-sectional survey conducted using a self-selected convenience sample of 206. The research rendered an exploration and an examination of the factors affecting trail-running athletes. The results were analyzed using several statistical techniques including Structural Equation Analysis. Our goal was to observe to what extent the Health Information Technology Acceptance Model patterns and outlines EU use of AT. This contribution, to the best of our knowledge, is new given that the obtained model can be an initial quantitative working primary tool for designers using the EU design method.
- Multiparameter optical monitoring of Madeira winePublication . Pereira, Vanda; Marques, José Carlos; Carvalho, Maria João; Chen, Monchu; Sol, Ricardo; Novo, Catarina; Bilro, Lúcia; Antunes, Paulo; Alberto, Nélia; Pinto, João LemosMadeira wine vinification process has been most ly empiric and requiring further studies. The present paper describes the existing pilot plant facility in Madeira Univer sity, with the installed controlled systems and safety devices. An advanced multi-parameter platform for real time moni toring and interactive data visualization is described and its potential use demonstrated.
