Influences of network latency on interactivity in networked rock-paper-scissors

ABSTRACT

This paper investigates the influences of network latency on the interactivity in rock-paper-scissors which two users do over a network by using live voice and video. By subjective assessment, we have assessed the interactivity in two cases. In one case, only one of the two users (referred to as the caller here) says, "Rock, paper, scissors, go!" and then both users try to show rock, paper, or scissors at the same time. In the other case, the two try to say, "Rock, paper, scissors, go!" simultaneously after one of them (i.e., the caller) has said, "Here we go," and then they try to pick rock, paper, or scissors at the same time. Assessment results show that the mean opinion score (MOS) of the caller tends to decrease as the network latency becomes larger in both cases. The MOS of the other user hardly depends on the network latency.
