Contextual, audience-verified screens for hospital lobbies · Bangkok
Alumbra sees without recording — the shipped binary contains no image encoder, and an automated audit enforces it on every release.
Alumbra reads the audience waiting at a lift, picks the message to fit, and proves what was seen — while storing nothing. Alumbra: Spanish, “it illuminates.”

Boxes, bands, counts — the device’s total perception, rendered live. There are no pixels behind this view to reveal.
The shipped binary contains no image encoder; a CI-gated audit — tools/privacy_audit.sh — fails any build that adds one. We run it in front of you, on your device, in your lobby.
Frames are destroyed in RAM in under 200 ms, and the frame type is not serializable by construction — the code has no way to write one.
Visible in the view beside this sentence — below five people, every box reads unknown.
A creative without its DoHSS approval reference does not play — the engine will not start.
No face recognition, no biometric templates, no recognizing a person who returns — tomorrow, or five minutes later.
No ethnicity, health, or income inference — refused on law, on science, and on taste. No emotion claims. No gaze certainty. The honest tier is head-pose attention, and we name it.
Not disabled — absent. No encoder in the binary; audited every release.
Below five people, age bands are suppressed everywhere — including our own operator view.
No DoHSS approval reference, no boot.
The hospital holds the kill-switch; we do not.
01 · light in
A camera above the screen reads the waiting area. Frames live in memory for under 200 milliseconds — counted, then destroyed.
02 · numbers out
Headcount, group composition, wide age bands when visible, seconds of attention. Aggregates only — below five people, the band breakdown suppresses itself.
03 · decision
A pair and a solo visitor wait; the screen weighs the mix and picks the message to fit — before the lift arrives. Decisions in under two seconds — gated in preflight.
A monthly report in standard out-of-home vocabulary — verified plays, attention seconds, audience mix — every line reproducible from the event log. DoHSS approval enforced on every creative. A per-venue kill-switch turns audience-reactive selection off and the screen falls back to its scheduled rotation; stated candidly for your DPO: in this mode the instrument still measures, it stops acting on what it measures. The pilot is reversible.
nulabs is a Bangkok lab building instruments that measure the physical world without surveilling the people in it. nulabs signs every instrument it ships. Alumbra is the first.
