Outline of Research at the Start

Pseudo-haptics(PH)は物理的触覚提示デバイスを用いなくとも擬似的な触力覚を提示可能な現象として着目されている一方,その効果が提示対象者や提示時間に依存し安定しないという問題を抱えている.そこで本研究では,PHを安定した触覚提示技術として確立するため,オンライン実験プラットフォームを構築して多様な特性の体験者に対するPH効果を大規模に収集し,収集データを用いて個々人の特性が効果量に与える影響や長期間PH刺激を提示することによる馴化の影響を明らかにする.更に,体験者の特性の違いや提示時間によって生じる錯覚効果量のばらつき・低減を防ぐ手法を構築し,その適用限界・有効性を明らかにする.

Outline of Final Research Achievements

In this study, we constructed an online experimental environment to elucidate the dependency of the Pseudo-haptics effect on the characteristics of the user and the duration of use, with a view to the engineering application of the Pseudo-haptics effect. We investigated the influence of individual characteristics such as age and gender, as well as the habituation effect due to long-term use. The results revealed that the Pseudo-haptics effect is less likely to occur in older individuals and those with lower visual and haptic self-localization abilities, and that the illusion effect diminishes with long-term use. Additionally, we confirmed that the illusion effect can be enhanced by increasing the sense of immersion in avatars, manipulating the appearance of virtual objects, and combining the effect with the pulling force illusion. The findings of this study provide important insights for designing VR experiences using Pseudo-haptics.

Academic Significance and Societal Importance of the Research Achievements

本研究は,Pseudo-hapticsの効果を左右する要因として,これまで考慮されてこなかった提示対象者の特性や提示時間の影響を体系的に明らかにした点で大きな学術的意義を有する.加えて,アバターへの没入感の操作やバーチャル物体の見た目の工夫,振動刺激との複合提示により,個人差を吸収しつつ錯覚効果を増強する手法を確立した.これらの成果により,Pseudo-hapticsの効果を安定的に提示できる可能性が示され,様々な体験者に対して違和感の無い触覚提示が可能になると期待される.加えて,Pseudo-hapticsを活用したコンテンツの実用化を促進する点で大きな社会的意義を有する.
