KANSEI evaluation of racket during tennis stroke

Abstract

This paper examined the KANSEI evaluation of racket during tennis strokes. To analyze it, questionnaires of SD method on rackets were taken to 12 subjects after actual tennis strokes, and psychological estimations were gotten. Using them, analyses of radar chart, cluster analyses, and principal component analyses were taken. At the same time, the motions of tennis strokes were measured and digitized using the 12 motion capture devices and were compared with psychological estimations. At first, personal preferences were charted. Secondly, subjects were classified into the three groups of experienced persons and the one group of novices from result of cluster analysis. Thirdly, experienced persons emphasized different evaluation factors from those of novices from result of principal component analysis. Finally, it was confirmed that the sum of the standard deviations of the locus during tennis strokes was related to the racket's comfort in experienced persons. Therefore, the results clarified the relationship between psychological estimations on tennis rackets and motion of human bodies during tennis strokes.
