A method to visualize lag between presenter and participants in screen sharing software

When a presenter is sharing a presentation with meeting participants, such that the slides are shown on a remote system (e.g., user's laptop), the presenter has no way of knowing when the participants' view is lagging behind the live presentation. This creates multiple problems, from confusion to disengagement on the part of the participants, to wasted time while the presenter

waits for participants to catch up, to awkward moments when the presenter has to explain what the participants should be seeing. In the worst case, the presenter remains completely unaware of the lag, and the entire presentation becomes ineffective.

No known solutions for this problem can be found.

A method is needed to provide presenters who are using screen-sharing software with an accurate indication of the lag participants are experiencing.

The novel contribution is a method to visualize lag between presenter and participants in screen sharing software. The method frequently creates identifiers on the presenter's system to indicate points of time. Links to the identifiers are included in the protocol sent to each participant at said time, and then returned once the participant has received the packet of data. The screen sharing software on the presenter's system captures the returned identifier and updates the participant's location within the presentation's sharing timeline.

This solution provides presenters insight to the amount of lag participants are experiencing as well as the ability to adjust the conversation to accommodate the lag participants are experiencing. This solution provides participants with a better experience, in which the running conversation more accurately aligns with the visuals. This also removes the obligation for participants to notify presenters of a lag.

Screen sharing works by sending compressed images of segments of the presenter's screen when the software detects differences. The...
