We tested the effects of local lag in several delay conditions: we found that the technique significantly improved performance, and that users did not rate local lag as more difficult or frustrating to ...
The main cause of this difficulty is network delay that disrupts people's ability to synchronize their actions with another person. ...
Network delay and its effects on collaboration Delay is a fact of life in real-world distributed applications because information must be transmitted across a network and processed at the other end before ...

In this paper, we report on a new implementation of telepointers (HPT) that is designed to provide smooth, timely, and accurate telepointers in real-world groupware: on busy networks, on cable and dialup ...
Although telepointers are valuable for supporting real-time collaboration, they are rarely seen in commercial groupware applications that run on the Internet. ...
If groupware is to be used by real groups in the real world, it must work under everyday network conditions. Groupware design should explicitly deal with performance issues. ...
