Tradeshow Investment is Enormous.
Measurement is Still Guesswork.
Exhibitors spend £50,000–£500,000 per show. Yet the majority report they cannot accurately measure engagement at stand level (UFI Global Exhibition Barometer, 2023). Post-event survey response rates typically average under 5%.
You Can't Ask Everyone
Post-event surveys reach a fraction of visitors. Those who walked away confused — your most important signal — leave no trace.
Lead Counts Miss the Story
Badge scans measure footfall, not engagement. A busy stand can still fail to convert when messaging triggers confusion rather than intent.
Stakeholders Demand ROI Proof
Marketing and event teams face pressure to justify tradeshow budgets. Anecdotal feedback no longer passes the CFO test.
Emotion Intelligence.
From Every Corner of Your Stand.
EchoDepth Events deploys cameras at strategic zones — stand entrance, product displays, demo areas, presentation stages — and analyses visitor expressions using 44 FACS Action Units in real time.
The output is not video footage. It is emotional signal data: engagement levels, confusion indicators, delight responses, and scepticism flags — mapped by zone, time, and staff interaction.
Cameras capture expression
Standard cameras at key zones. No specialist hardware required.
44 Action Units analysed
FACS engine maps facial movement to discrete emotional states in real time.
Signals only — faces discarded
Raw frames are deleted immediately. Only anonymised scores persist.
Actionable dashboard delivered
Live and post-event analytics show what worked, what confused, where to improve.

Zero Faces Stored.
Full GDPR Compliance.
EchoDepth Events was designed from the ground up with privacy as a core architectural constraint. We adhere to GDPR Article 25 — meaning PII storage is structurally impossible, not just policy-blocked.
What we analyse: facial muscle movement patterns mapped to FACS Action Units.
What we store: anonymised emotional signal scores.
What we never store: faces, biometrics, images, or any identifiable data.
No Biometric Data Stored
Facial geometry processed ephemerally and discarded at the edge.
GDPR Article 25 Architecture
Privacy by Design baked into the system, not bolted on.
No Re-identification Risk
Aggregate emotional signals cannot be reverse-engineered to individuals.
Data Minimisation
Only signals necessary for analysis are retained — nothing more.
No Consent Barrier
Because no personal data is processed, standard CCTV signage is sufficient in most contexts.
UK & EU GDPR Aligned
Designed for compliance with both UK GDPR and EU GDPR frameworks.

Real Results from Real Events
"For the first time, we knew exactly which part of our stand was causing confusion — and we fixed it mid-show."
"The privacy architecture was the first question from our legal team. Once they saw no face data is stored, sign-off was immediate."
"We justified our entire show budget to the board in 20 minutes. The emotion data told a story badge scans never could."
