Abstract—In this paper, we investigate the influence of network delay on weight perception in networked virtual environment by experiment. In the experiment, each of two users manipulates a haptic interface device, and the users collaboratively lift up a stick by holding two ends of the stick in a 3D virtual space. A weighted ball is placed on the stick, if one end of the stick is lower than the other end, the ball moves to the lower end. The users try to keep the ball at the center of the stick while lifting up the stick. We also implement the local lag control as Quality of Service (QoS) control and compare results with the control and those without it. Experiment results demonstrate that the local lag control is effective, and it is possible to keep the ball around at the center when the network delay is smaller than about 50 ms.

Index Terms—Haptic sense, network delay, weight perception, QoS.
