Outline of Final Research Achievements

We realized an aerial drawing interface that enables stable drawing with “subtle" force support from the spatial orthogonal axes. In FY2020, we proposed "fuzzy static friction force by orthogonal axes," which is a virtual extension of the real "static friction force," and realized a system that enables the user to experience this force with a force feedback device. In FY2021, we implemented this system in a 3D hand-drawn CAD interface and confirmed that it contributes to the stabilization of aerial drawing. We also proposed "fuzzy static friction force in the normal direction of a curved surface," which is an extension of the “fuzzy static friction force by orthogonal axes." In FY2022, we produced a web demo software that implements the “fuzzy static friction force by orthogonal axes" and the “fuzzy static friction force in the normal direction of a curved surface."

Academic Significance and Societal Importance of the Research Achievements

本課題の核心は「ファジー静止摩擦力」なる超現実的な仮想静止摩擦力のモデルをファジー理論により構築し、これを力覚フィードバック装置で実現することで、仮想空間中の直交軸やオブジェクトから「さりげない」力覚的サポートを受けて自在かつ安定的な描画を行える画期的な空中描画インタフェースを実現できることを実証したことにある。この成果はファジー理論の新たな応用を切り拓くとともに力学フィードバック装置の新たな活用を提示するもので、理論および応用の両面において学術的に新たな知見を与えるものである。
