In the second year of my master degree, the Autonomous Lab of Ergonomics, received a proposal for the study of a new concept of bicycle. The Lab invited me to elaborat this study, wich would be at the same time my master thesis. This new concept of bicycle have elliptical wheels and we were interested in visual and performance impact over the user. So I developed two studies, one with just visual contact evaluating UX through two emotional questionnaire SAM and GENEVA. The second study is based on visual and interaction through a predefined course with the bicycle, and in the end the aplication of the same questionnaires and one more with subjective usability dimensions.
