Set up one camera facing the audience and the room is read live, in the browser, on the day. Not a survey sample of who replied. You get each signal by name, and which part of the session moved it.
Works from one fixed camera pointed at the audience, not at the stage. The video stays on the device; only room-level numbers are kept. No wearables, no surveys.
9:14 a.m. the Tuesday after. The budget is on the screen. Finance asks “what did we actually get for the keynote?” You have a survey 12% answered, three weeks late.
A camera pointed at the seats catches when the room leans in and when it drifts. Proof of Impact reads it live and turns it into measured signals you can take to finance.
Sample
Read from the room as one group, not person by person.
The share of the people in view whose heads face the front, given as a likely range over those people. It reads which way heads face, not where eyes look.
How many faces the read found. A floor, not a headcount: in a dense or dim room the detector misses some, so the room is at least this size.
Anything the read could not stand behind is left out, with the reason printed in its place.
Sponsors are done paying for “estimated reach.” Hand them the attention their activation earned, read from the room and given as a range. That is the difference between a renewal talk and a discount talk.
Sample
Can the signals be reported as one score for the room?
Method: we set the pass marks first, then test against them. Until they pass, your report names each signal on its own.
Did the room react together, or in scattered ones and twos?
Method: how much of the audience reacts at the same time. Pass mark: the same session, read from two halves of the footage, agrees to at least 0.75 (ICC). Not in your report until it passes.
How long did the room stay with the speaker, not only look up?
Method: head direction across the footage, rolled up into how long attention held. Pass mark: agreement with trained human coders of at least 0.60 (Pearson r), within 0.15 on average. Not in your report until it passes.
When did the room erupt, and for how long?
Method: how loud and how long the room's sound peaks run. Pass mark: not set yet, so it is not in your report.
Setup is one camera and a clear sightline to the audience, placed before the room fills. Our team handles it, and everything after it. Your programme does not change, your speakers do nothing differently, and there is no attendee app to install, no code to scan and no survey to push.
What does setup actually take?
In practice: position one camera at the front, pointed back at the seats, check the framing covers them, start it. That is the install. It faces the audience, not the stage, because the read is of the room.
What do we have to do differently?
In practice: nothing. No wearables, no attendee app, no survey to push, no change to how a speaker is introduced or how the session runs.
Who does the work on the day?
In practice: we do. We set the camera, run the capture, do the read and build the report. Your team gets a named contact from the first call through to the report landing.
Does it scale past a single session?
In practice: the same setup repeats per room. Rooms running at once need a camera each, which is one of the things a full-event quote is built from.
Prices in Canadian dollars. The single report is a one-time charge, not a subscription, and nothing on this page renews. Full-event pricing is quoted per event.
