Study on Effects of Network Characteristics on Cooperation Performance in a Desktop CVE System
The influences of network characteristics (e.g. latency,packet loss) on the task performance in desktopCollaborative Virtual Environment (CVE) systems werestudied. In the experiment, two remote partners workedtogether to manipulate shared virtual objects over anetwork, and a network emulator was utilized to simulatethe real network. The task in the experiment was tominimize the time to transfer a frame through a rod with nocollisions. The performance of human subjects wasmeasured and analyzed quantitatively as a function ofnetwork latency and packet loss rate. The experimentresults show that the delay had little effect on the taskperformance while the network latency was less than 200ms and it was acceptable while the network latency wasless than 500 ms; the packet loss had no effect on the taskperformance while there were 20 state update messagesreceived and it was acceptable while there were more than10 state update messages received.
