Working efficiency was analyzed in direct manipulation of virtual objects with a wearable fingertip force display system. Two kinds of virtual objects were utilized that allows the deformation of 5mm or 20mm. The elastic coefficient of the object was varied from 0 to 1600 N/m. The grasp and transport task was performed with 30ms sample interval as well as 60ms in five volunteers. Following trends were observed ; 1)the better working efficiency was obtained with larger elastic coefficients ; 2)the difficulty of the task is regulated by the allowed deformation rather than the allowed force ; 3)the better working efficiency was obtained at higher sample rate condition. It was concluded that the working efficiency can be improved by using force display devices at relatively lower sample rate by selecting the adequate elastic coefficient.
