Abstract;It is expected to make use of computer graphics (CG) technology for the studies on anticipation skills in sports. The purpose of this study was to clarify the differences in the characteristics of the anticipation skills when presenting the tennis serve motion with CG animations by comparing with VTR movie. On the bases of the coordinate data of the human body, CG animations were made by a CG modeling software. In the assessment of the CG, we examined anticipation skills when twelve expert tennis players anticipated serve direction during the observation of projected serve motion. Although our results showed that the anticipation accuracy and judgment timing for the presentation of CG animations were similar to that of VTR movie, the searching strategies were different. Therefore it is suggested that the difference of searching strategies is yielded by the smaller amount of information in CG animations than in VTR movie. (author abst.)
