◆VRは、危険な環境や安全訓練、細かい運動スキルのトレーニングに使用されており、この研究の結果は、効果的な学習環境の構築に役立ちます。特に、アバターが自分に似ていることが学習に有益であり、VRを使用する場合、没入感や深度知覚が高まります。
◆研究者は、工場労働者のトレーニングなど、さまざまな分野でアバターカスタマイズがどのように効果的かを調査しています。これにより、カスタマイズがもたらす効果を活かした学習プログラムの開発が期待されています。

ABSTRACT
Virtual environments can support psychomotor learning by allowing learners to observe instructor avatars. Instructor avatars that look like the learner hold promise in enhancing learning; however, it is unclear whether this works for psychomotor tasks and how similar avatars need to be. We investigated ‘minimal’ customisation of instructor avatars, approximating a learner’s appearance by matching only key visual features: gender, skin-tone, and hair colour. These avatars can be created easily and avoid problems of highly similar avatars. Using modern dancing as a skill to learn, we compared the effects of visually similar and dissimilar avatars, considering both learning on a screen (n=59) and in VR (n=38). Our results indicate that minimal avatar customisation leads to significantly more vivid visual imagery of the dance moves than dissimilar avatars. We analyse variables affecting interindividual differences, discuss the results in relation to theory, and derive design implications for psychomotor training in virtual environments.
