A technique to provide constant feedback of "display latency" in webconferencing for each participant to help presenter adjust the speed of presentation .

On a web conference there is always a "display latency" for each participant i.e. there is a time lag between information being presented by the presenter and the same being visible to the participants. Also, time taken to load information being presented for one participant varies from another i.e. the display latency for each participant may vary. The display latency or variation in load time depends on the connection speed of each participant. A participant with a faster connection will load all information faster than a participation with a slower connection. This poses a problem for the Presenter as he/she needs to wait until all participants have the presented information loaded else participants with slower speeds will be out of the synch with what is being presented.

Currently, the only ways to resolve this problem is by verbal interventions i.e. -
1. Either the Presenter seeks verbal feedback from all participants on whether the information presented is loaded for all OR
2. The participants interrupt the presenter asking him/her to wait till the information is loaded.

There is no automated way to receive feedback for the Presenter or there is no way for the participants to control the flow of the presenter. Often times, due to time constraints, the presenter is forced to proceed even if some participants have not received all the information being presented. The participants with slowest connection speeds are most affected due to this issue. Instead of repeatedly interrupting, they eventually drop off, which results in a inconclusive meeting thereby wasting time. The problem is only compounded when the participants are logged into the web conference in a listen only mode, in that case there is no way for the participants to let the presenter know that they are not able to see what the presenter is presenting.

The article described herein tries to solve the problem of display latency in a web conference by providing mechanisms -
1. For the presenter to receive continuous, automated feedback about the information visible to the participants. While network or device latency cannot be solved when the conference is ON, constant feedback to the presenter will help him adjust his speed of presentation seamlessly.

2. For the participant to switch to a light weight version of the presentation, thereby reducing the load time of slides.

We propose a technique with a -
1. Visual Indicator for the presenter - Web conference will have a visual indicator for the presenter to know how many participants are seeing the page being presented. This statistics can be shown as a traffic light or a progress bar (percen...
