Resumo

O mouse, apesar de ser insubstituível para a manipulação das GUIs, não desempenha todas suas funções com igual eficiência. Algumas tarefas freqüentemente realizadas com este dispositivo são pouco compatíveis com sua natureza, com destaque para aquelas necessárias na realização de desenhos. Este estudo objetivou avaliar se as tarefas executadas com dois diferentes tipos de mouses exigem diferentes pressões da mão. Foram desenvolvidos procedimentos e equipamentos capazes de realizar medições através de sensores FSRs e um AFG (strain gauge). Os resultados apontaram diferenças (p ≤ 0,05) entre os mouses, o que representa uma maior dificuldade nas maiores pressões.

Abstract

Besides the computer mouse being irreplaceable for the GUI manipulation, it is not equally efficient for all kinds of tasks. Many common tasks done with the aid of this pointing device, such as drawing, are incompatible with its own nature. The present study compares different mouse types by the pressure required from the user’s hand during their manipulation. Specific equipment and procedures were developed to handle this comparison by the means of FSR and AFG (strain gauge) sensors. The results showed significant differences (p ≤ 0.05) between the mouses, suggesting higher task difficulty in cases of higher pressures registered.
