How does iPhone Sound Recognition trigger the sleeve without a custom App Store app?

When iOS Sound Recognition detects a doorbell, siren, dog bark, or baby cry, it posts a local system notification that bridges straight to the sleeve over Bluetooth ANCS (Apple Notification Center Service).

Will this wake me up if I am asleep under heavy blankets?

No—LEDs require visual line-of-sight or peripheral awareness. It is designed for awake peripheral alerts (working at a desk, cooking, wearing noise-canceling headphones, or walking around the house), not as an under-duvet sleep alarm.

Is this a clinical medical device?

No. The Garment GUI LED & Touch Sleeve is a consumer programmable wearable display and Bluetooth macro interface.

Why Watch Buzzes and Phone Flashes Miss Critical Household Alerts

A single generic buzz guesses: One wrist vibration leaves you unsure whether it was a doorbell, a kettle, or a smoke alarm.
Color plus words: 256-pixel animations and explicit scrolling words along your forearm tell you what happened in one glance.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
