See who's there. See who's watching.
Counts, dwell time and attention for every screen and zone — tuned to your space so the numbers reflect what really happened. Every measurement comes with a confidence score.
Four calibrated metrics, transparent definitions.
Every metric has a precise, documented definition. We publish what we measure, how we measure it, and the known limitations.
OTS (Opportunity To See)
Calibrated count of people with an opportunity to see the screen, within the display exposure zone, during the measurement window. Anchored to screen geometry and camera pose calibration.
Dwell Time
Duration an individual remains within the measurement zone, measured from first detection to exit. Reported as averages and bucketed distributions (0-5s, 5-15s, 15-30s, 30-60s, 60+s).
Attention
Proportion of dwell time where the individual is oriented toward the display surface. Reported as attention rate (0-1) and total attention events with confidence scoring.
Audience Window
A time-bounded observation period with aggregated audience metrics, confidence scores, and quality flags. Each window carries model_version, calibration_version, and event lineage.
Sample Dwell Distribution
Calibration requirements and standards alignment.
Accuracy depends on proper calibration. We are transparent about requirements and known limitations.
- Camera must be positioned with clear line-of-sight to the measurement zone
- Screen geometry (dimensions, height, angle) must be configured during setup
- Camera pose (position, angle, field of view) must be calibrated per deployment
- Zone boundaries must be defined to delineate the display exposure area
- Calibration should be re-verified after any physical changes to the installation
- OTS counts people in the zone, not guaranteed ad viewers — attention rate provides the viewing signal
- Dwell accuracy depends on detection continuity; occlusion may cause under-counting
- Attention detection uses head orientation, not eye tracking — confidence varies with distance and angle
- Calibration confidence degrades if the physical installation changes without recalibration
- Low-light and extreme weather conditions may reduce detection accuracy (reflected in quality_flags)
100% edge processed.
Raw sensor feeds never leave the hardware device. Only calibrated, anonymous audience metrics are transmitted to the cloud.
Camera
Standard USB or IP camera feed
Edge Processing
Detection + calibration locally. Frames discarded instantly.
Calibrated Signal
OTS, dwell, attention with confidence and lineage.
Cloud API
Dashboard, API, forecasting, and partner integrations.
A fundamentally different approach.
Traditional analytics tracks demographics. We track calibrated audience presence and attention.
