How to Review Audience Movement Signals

With informed participant consent, an aggregated movement view can help a presenter return to moments in recorded source footage and ask what happened in the room.

What it cannot show

Facial movement does not measure attention, comprehension, engagement, satisfaction, or emotional tone. Do not use individual or group scores to grade learners, evaluate employees, profile attendees, or automate session decisions.

Responsible workflow

Prefer direct participant feedback, collect only the data needed for an approved purpose, preserve context, report uncertainty, and keep any follow-up with qualified human reviewers.
