Everything You Need to Measure What Matters
Real-time emotion analytics, privacy-first architecture, and actionable ROI intelligence — all from a single camera unit per zone.
Why Traditional Event Metrics Fail
Badge scans tell you who arrived. Post-event surveys capture fewer than 5% of attendees — and only the ones motivated enough to respond. Neither tells you what actually happened in the room: which messages landed, where confusion emerged, or why engagement dropped at 2:45pm on Day 2.
EchoDepth Events bridges this measurement gap using computer vision and the Facial Action Coding System (FACS) — the same framework used in clinical psychology and law enforcement for over 45 years. We measure what people genuinely feel, not what they later claim to remember. The platform runs in two tiers, so compliance effort matches the depth of insight required. Standard tier delivers anonymous behavioural analytics — footfall, dwell time, movement against stillness, and crowd density by zone — with no facial analysis and no consent overhead, which makes it deployable at any event for any audience. Deep tier adds the full FACS taxonomy, all 44 Action Units processed in real time, and requires delegate opt-in collected at event registration. Both tiers process video on an edge device at the venue and discard each frame immediately, so no face image or biometric record leaves the room or is retained afterwards.
Two Tiers, One Platform
Choose Standard tier for anonymous behavioural analytics with zero consent overhead, or Deep tier for full emotional signal analysis with delegate opt-in. Both deliver real-time dashboards and comprehensive post-event reports.
44-AU Facial Action Analysis
The complete FACS taxonomy — all 44 Action Units — processed in real time. Our computer vision engine detects micro-expressions lasting as little as 1/25th of a second, mapping AU activation patterns to discrete emotional states including confusion, delight, scepticism, and genuine interest. This is the same methodology used in clinical research and deception detection for over four decades.
Privacy-by-Design Architecture
Edge processing ensures no face images or biometric data ever leave the venue. Raw video frames are discarded immediately after Action Unit extraction — making biometric data retention technically impossible, not just policy-prohibited. This architecture satisfies GDPR Article 25 (Data Protection by Design) and substantially reduces consent requirements compared to traditional biometric systems.
Real-Time Dashboard
Live zone scores, engagement heatmaps, and emotional trend lines visible during the event. The dashboard updates every 30 seconds with rolling 5-minute averages, letting you identify underperforming stands while there is still time to reassign staff, adjust demonstrations, or investigate issues. Exportable screenshots for post-event team debriefs.
Zone-Level Analytics
Segment your floor plan into named zones — product demonstration areas, networking lounges, refreshment stations, entry points, and sponsor booths. Compare engagement scores between zones to understand which areas capture attention and which generate passive footfall. Zone boundaries are configurable before deployment and can span multiple camera units for larger areas.
ROI Attribution
Post-event reports map emotional engagement scores to zone dwell times, conversion event timestamps, and lead capture data. Correlate high-engagement moments with badge scan timing to identify which interactions drove qualified leads. Calculate effective cost-per-engagement and compare against industry benchmarks for tradeshow ROI measurement.
Confusion Signal Detection
Elevated AU4 (brow lowerer) patterns trigger confusion alerts in real time. When confusion scores exceed thresholds, you receive immediate notification to investigate. This pinpoints exactly which messaging, demonstrations, or product explanations are generating confusion rather than clarity — letting you coach staff or adjust content before the event ends.
No PII — No Consent Overhead
Because no biometric data is retained and no individuals are identified, visitor consent requirements are substantially reduced under GDPR and UK GDPR. Your events team focuses on running the event rather than managing consent collection workflows. Standard tier operates entirely without personal data processing.
Post-Event Reporting Suite
Structured PDF and data export covering zone performance, time-series engagement trends, and comparative benchmarks. Reports are delivered within 5 working days of event completion, including executive summary, zone-by-zone breakdown, peak engagement moments, and actionable recommendations for your next event.
Staff Effectiveness Analysis
Measure how visitor emotional response changes during staff-led demonstrations. Track which team members generate the strongest engagement uplift and identify coaching opportunities for underperformers. Deep tier captures engagement deltas before, during, and after staff interactions — objective evidence for training investment decisions.
