Influences of Network Latency of Voice and Haptic Media on Efficiency of Collaborative Work

This paper deals with collaborative work in which two users lift and move an object cooperatively by using haptic interface devices while one of the two is instructing the direction of the object’s movement by voice. By experiment, we investigate the influences of the network latency of voice and haptic media on the efficiency of the work. We also clarify the effect of voice by making a comparison of the
