DeltaFinger：指先に高忠実度の力ベクトルを提示する3自由度ウェアラブル触覚ディスプレイ
DeltaFinger: a 3-DoF Wearable Haptic Display Enabling High-Fidelity Force Vector Presentation at a User Finger
ウェアラブルなデルタ機構で指先を誘導し、仮想物体との相互作用力を3次元力ベクトルとして提示する触覚デバイスを開発した。平均0.6radの精度で力ベクトルを知覚でき、他の指の動きを制限しない。

This paper presents a novel haptic device DeltaFinger designed to deliver the force of interaction with virtual objects by guiding user's finger with wearable delta mechanism. The developed interface is capable to deliver 3D force vector to the fingertip of the index finger of the user, allowing complex rendering of virtual reality (VR) environment. The developed device is able to produce the kinesthetic feedback up to 1.8 N in vertical projection and 0.9 N in horizontal projection without restricting the motion freedom of of the remaining fingers. The experimental results showed a sufficient precision in perception of force vector with DeltaFinger (mean force vector error of 0.6 rad). The proposed device potentially can be applied to VR communications, medicine, and navigation of the people with vision problems.
