Evaluating decorators for haptic collaboration over Internet

One of the known problems with shared object manipulation in collaborative virtual environments (CVE) is the disruptive effect of network lag in collaboration sessions. It is widely recognized that delay and jitter cause significant problems for CVEs. Most solutions to this problem revolve around techniques to compensate for this lag at the networking level. More recently, the usage of visual queues indicating network lag to the user have shown to be effective. In this article we examine the latter for tele-haptic applications, and we find out an appropriate visual queue specifically for the low delay and jitter requirement necessary for closely-coupled collaborative tasks.
