没入型仮想空間における力覚呈示デバイスHapticGEARの開発とその評価

摘要

In this paper, we describe the design and the implementation ofa force display for immersive projection displays such as CAVE or CABIN. To give the user maximum freedom of motion in a large virtual space, it is necessary to use a portable force display that is grounded on the useru27s body. Various nonportable force displays have been developed, but their workspace is small and restricted. Therefore, we developed a portable (wearable) force display called HapticGEAR which makes use of the tension of wires grounded on the useru27s back. HapticGEAR is designed to have fewer effects on the useru27s motion and to maximize output force in useru27s workspace. Finally, we evaluated this device through the basic experiments in CABIN.
