Influences of Network Delay and Moving Velocity on Virtual Cooperative Work with Haptic Sense

Abstract— In this paper, we investigate influences of the network delay and moving velocity on virtual cooperative work with haptic sense by experiment. In the work, each of two users operates a haptic interface device, and the two users collaboratively raise a stick in a 3D virtual space. The stick has a weighted ball, and the ball moves to the lower end along the stick if one end of the stick is lower than the other end. They try to keep the ball at the center of the stick while raising the stick. Experimental results demonstrate that it is possible to keep the ball around at the center when the network delay is small. We also show that there exists the optimal moving velocity of the ball depending on the network delay.
