Haptic-Visual Assistance of Remote Collaborative Task and Evaluation of Workload

在利用可穿戴指尖力显示设备的虚拟环境中，为辅助物体碰撞认知和远程协作物体处理，对增强的触觉显示方法进行了实验研究。实验证明，增强的触觉信息在主观上辅助了虚拟物体的处理，提高了处理效率。通过计算远程用户之间的伪约束并通过触觉显示约束力来辅助远程协作处理。

Towards the assistance of the collision cognition of handling object and the assistance of remote cooperative object handing, the enhanced haptic display methods were experimentally studied in the virtual environment that utilizes wearable fingertip force display devices. It was demonstrated that the enhanced haptic information subjectively assists the virtual object handling and improves the handling efficiency. It was also demonstrated that the remote cooperative handing is assisted by the computed pseudo-restriction between the remote users and the haptic display of the restriction force.
