On-device sensing
Face tracking runs entirely in the browser and is discarded frame by frame. No image or video ever leaves the device.
01 / Concept
The sky is the first shared surface.
The same stars for everyone, everywhere. Constellations of the Present rebuilds that surface for the network age: a collective sky that exists only in the living present, built from moments instead of profiles.
Each visitor’s presence is sensed entirely on their own device. The camera reads expression, attention and engagement in real time; the reading is quantised and immediately reduced to a non-reversible hash — a "moment-hash" — with a random nonce. Only that anonymous code leaves the device.
02 / Privacy
Nothing raw is transmitted, stored or logged.
Moment-hash
Quantised expression and engagement values are hashed with a random nonce. The result is anonymous and non-reversible.
Opt-in audio only
The microphone feeds only a live audio level into an ambient drone. It never records, never transmits, never leaves the browser.
03 / Technical
A privacy-by-design stack.
- 01 Vite + TypeScript build
- 02 Three.js — WebGL, bloom, tonemapping ACES render
- 03 MediaPipe Face Landmarker (on-device) sensing
- 04 Web Crypto SHA-256 — seed derivation hash
- 05 Mutual k-nearest-neighbour topology graph
- 06 Bézier arcs with progressive reveal drawing
- 07 Global emotional gradient, gamma corrected colour
- 08 Anonymous realtime — no personal data network
Joy → Surprise → Anger → Sadness → Calm → Neutral : one gradient, six readings
Look up.
Your star appears only while you are present — and disappears the moment you look away.
