Building Spactacle
Updates
Research, engineering, prototypes, product decisions and what we learn while building Spactacle.
[Fixture] Measuring physical shelf engagement: from dwell to conversion
A framework for turning unstructured shopper interactions into decision-grade retail telemetry.
[Fixture] Benchmarking stereo depth models on embedded edge accelerators
Evaluating real-time disparity estimation across diverse retail ambient lighting conditions.
[Fixture] Selecting the optical stack for multi-tier retail shelving
Evaluating lens distortion, baseline separation, and depth precision for top and bottom shelf zones.
[Fixture] Defining the behavioral event schema: see, touch, convert
How we categorize shopper interaction primitives into structured, reproducible time-series signals.
[Fixture] Building Spactacle: founding principles and product focus
Why we are committed to building restrained, privacy-first technology that makes physical retail measurable.
[Fixture] Evaluating synthetic store environments for occlusion edge cases
Using physics simulation to generate complex interaction edge cases before field deployment.
[Fixture] Passive thermal management in ceiling-mounted retail sensors
Dissipating edge compute heat without active fans in dusty retail environments.

This archive is intentionally chronological. At much larger scale, we would add year grouping or pagination; at ~50 updates, search + category filtering is sufficient and faster to scan.
