The Problem with Traditional Research
Your participants are performing, not responding.
Every traditional research method puts the observer effect at its centre. The moment people know they're being studied, the data is compromised.
Traditional methods — what you get
- Social desirability bias — participants answer what they think researchers want to hear, not what they actually feel
- The articulation gap — people simply cannot accurately describe their emotional responses in words
- Post-rationalisation — conscious reflection after stimulus exposure distorts and rewrites emotional memory
- Peer pressure in groups — dominant voices suppress minority responses; groupthink contaminates qualitative data
- Recall bias — post-session surveys ask people to remember how they felt, not how they actually felt
- Geographic lock-in — facility-based research limits participant diversity and drives up cost
- No moment-to-moment data — you get a rating at the end, not a signal throughout
EchoDepth Insight — what you get instead
- Involuntary physiological signal — facial Action Units cannot be consciously controlled; they reveal genuine response
- No articulation required — VAD scores are computed from behaviour, not language
- Real-time, in-stimulus capture — emotional data is recorded at the moment of exposure, not recalled afterwards
- Individual, not group — every participant is analysed independently; no peer contamination
- Remote delivery — global participant access from any device with a camera
- Moment-to-moment timeline — see exactly when and where emotional response peaks and drops during the stimulus
- Quantified, comparable output — VAD scores enable statistical analysis, segment comparison and longitudinal tracking
How EchoDepth Insight Works
Four stages. One session. Truth throughout.
Recruit & brief
Participants join remotely via any device with a camera. Consent is captured digitally. No facility. No travel. Global access.
Expose & capture
Stimuli — concepts, packaging, messaging, video, or interview questions — are delivered in-session. EchoDepth captures 46 facial Action Units continuously throughout exposure.
Score & flag
VAD scores are computed in real time. Key moments — emotional peaks, drops, surprise signals — are automatically flagged with timestamps. Moment-to-moment emotion curves are generated per stimulus.
Report & recommend
Structured session reports with emotion timelines, group aggregates, segment comparisons and confidence scores. From insight to marketing recommendation in a single workflow.
Industries
Where emotional truth changes outcomes.
Pharmaceutical
Remote patient interviews, HCP engagement research, clinical trial experience assessment, drug messaging testing and marketing material evaluation. All with moment-to-moment emotional capture.
Explore pharma use cases →FMCG & Consumer Goods
Packaging concept testing, brand identity evaluation, ad and creative testing, new product introduction research and shelf presence studies — all without the bias of articulation.
Explore FMCG use cases →Healthcare & Devices
Patient communication testing, device usability research, health information comprehension studies and treatment preference interviews that capture authentic emotional response.

"The gap between what consumers say in research and what they do in market has always been the central problem of insights. EchoDepth measures the signal that language cannot — the involuntary physiological response that drives behaviour."
EchoDepth Insight does not claim to read minds. It measures Valence, Arousal and Dominance — the three quantifiable dimensions of emotional state — at the moment of stimulus exposure. Read our ethics approach →
