Characteristics and Differences in the Verbal Responses of Expert and Novice Basketball Coaches Elicited by Cognition of Fixed Camera Images and VR Images^*

抄録

The aim of this case study was to reproduce the images recorded by a fixed video camera and those recorded by a 360-degree omnidirectional camera to investigate characteristics and differences in how expert coaches and novice coaches perceive such images, based on differences in the coaches’ verbal responses during basketball games. From the findings, 3 points were clarified. 1) It appeared that novice coaches were unable to observe phenomena in VR images but were able to do so from fixed camera images. In contrast, proficient coaches were considered highly likely to observe such phenomena from both types of images. 2) From fixed camera images, both novice and proficient coaches tended to observe phenomena objectively, in terms of being able to describe the situation and offer guidance and criticism. 3) From VR images, proficient coaches tended to offer praise or instructions on the basis of specific individual characteristics of player or team movements.
