Resumo(s)
O interesse nas bicicletas tem aumentado exponencialmente, no sentido de as tornar um produto mais eficaz e útil. Neste âmbito, e numa vertente de lazer, surgiu um novo conceito de bicicleta, fora do considerado comum e com um carácter diferenciador. Esta bicicleta, a bicicleta ELIP, embora semelhante às bicicletas consideradas normais, apresenta rodas elíticas, controladas independentemente. Torna-se importante compreender a perceção dos utilizadores, face à funcionalidade da bicicleta e à satisfação que lhes transmite, tendo em conta uma diversidade de fatores de decisão. Para tal, focaram-se duas vertentes da Ergonomia, nomeadamente a Usabilidade, perceção da performance, e a Experiência de Utilização, que é constituída pela primeira, conjugada com a análise das respostas emocionais dos utilizadores.
São escassas as metodologias de avaliação da Usabilidade e Experiência de Utilização, face a produtos físicos, nomeadamente, bicicletas. Nesse sentido, o presente estudo teve como objetivo desenvolver uma abordagem metodológica sumativa, de baixo custo e de fácil aplicação, que envolva de forma sistémica a avaliação destes parâmetros. É, assim, um estudo de contributo para a avaliação da bicicleta ELIP.
A investigação encontra-se dividida em dois estudos: Estudo I e Estudo II, sendo que no primeiro é avaliada a interação com a bicicleta, através de um questionário que engloba a Usabilidade e duas ferramentas de análise das respostas emocionais dos utilizadores, compreendendo-se a Experiência de Utilização, na sua totalidade. Já, no segundo estudo, dividido por dois momentos de recolha, A e B, é focada apenas a observação da bicicleta e é avaliada somente a resposta emocional. É de notar que as amostras de ambos os estudos são independentes, não existindo relação entre estas. A amostra do Estudo I é composta por 30 participantes e a amostra do Estudo II por 50 participantes (Momento A – 36; Momento B – 14).
A metodologia desenvolvida demonstrou-se fácil de aplicar, com um custo muito baixo e revelou eficácia na obtenção de resultados e sua descriminação. Os resultados obtidos demonstram algumas contrariedades entre ambos os estudos, sendo que no primeiro estudo, a bicicleta considerada normal apresenta resultados mais positivos, com melhor usabilidade e uma melhor experiência de utilização. Relativamente à ELIP, à medida que se aumenta a sua oscilação, a avaliação dos utilizadores torna-se mais negativa. É de realçar, no entanto, que, mesmo representando um maior desafio, é a bicicleta ELIP que se apresenta como mais entusiasmante. No segundo estudo, os resultados revelaram respostas emocionais mais positivas na bicicleta ELIP.
Este estudo permitiu indiciar a metodologia criada como eficaz e potencialmente adequada à análise deste produto. Verificou-se um entusiasmo geral face à bicicleta ELIP, no entanto, negativamente influenciado pelas dificuldades associadas à sua utilização. É de notar que este é um estudo inicial e deve ter-se precaução na interpretação e generalização dos dados obtidos, sugerindo-se um novo estudo com uma amostra mais abrangente e aleatória.
The interest in bicycles has increased exponentially, in order to make them a more effective and useful product. In that context, and in an leisure component, a new concept of bicycle has emerged, considered out of the ordinary and with a differential character. This bicycle, the ELIP bicycle, although similar to bicycles considered normal, it presents elliptical wheels, independently controlled. It is important to understand the perceptions of users, face to the functionality of the bicycle, and the satisfaction that transmits, considering a diversity of decisions factors. For to do this, it focused in two aspects of Ergonomics, namely Usability, performance perception, and User Experience, which is composed by the first, together with the analysis of the user’s emotional response. There are scarce evaluation methodologies of Usability and User Experience, face to physical products, in particularly bicycles. In this sense, the present study aimed to develop a summative methodological approach, inexpensive and easy to apply, involving systemically the assess of these parameters. It is, thus a contributive study to evaluate the ELIP bicycle. The research is divided into two studies: Study I and Study II, wherein the first, the interaction with the bicycle is assess, through a questionnaire comprising Usability and two tools of emotional responses of users, comprising the User Experience in its totality. In the second study, divided by two moments of collection, A and B, is focused only in the observation of the bicycle assessing only the emotional response. The sample of Study I consists of 30 participants and the sample of Study II by 50 participants (Moment A – 36; Moment B – 14). The developed methodology has showed easy to apply, inexpensive and it reveals itself effectiveness in achieving results and its discrimination. The results show some contradictions between the two studies, wherein the first study, the bicycle considered normal has more positive results with better levels of usability and a better user experience. Regarding ELIP, as it increases its oscillation, the evaluation of the user becomes more negative. It is noted, however, that even representing a bigger challenge, is the ELIP bicycle itself that presents as more exciting. In the second study, the results revealed more positive emotional responses in ELIP bicycle. This study allowed to indict the methodology created as effective and potentially adequate to analysis of this product. There was a general enthusiasm due to the ELIP bicycle, however, adversely affected by the difficulties associated with its use. It should be noted that this is an initial study and it has to be caution in the interpretation and generalization of data, suggesting a new study with a more comprehensive and random sample.
