Pebble senses and stays present — pairing acoustic fall detection with a warm AI companion, so help arrives in seconds and independence doesn't mean isolation.

Pebble, always present — never intrusive.
She fell at home and broke her arm, unable to reach her phone. Talking to other older adults living alone afterward, the same fear kept surfacing — not the fall itself, but the thought of lying there with no one coming. That fear has a name, basophobia, and it's self-defeating: it makes people move less, which only raises their risk of falling again. Pebble exists so that fear doesn't have to be part of aging alone.
No cameras, no wearable to remember, and nothing recorded. Every sound Pebble hears is processed on-device and never stored or sent anywhere — it just responds like someone who's paying attention.
A 4-microphone array picks up the short, sharp sound signature of a fall — even through a closed bathroom door or over a running shower.
60GHz radar confirms someone's actually there, even in total darkness — cutting false alarms instead of crying wolf.
Pebble checks in by voice first. No answer, or a call for help — and family is alerted immediately.
Between emergencies, Pebble is easy company — a voice for check-ins, reminders, and conversation. It's built to feel like presence, not surveillance.
When something's wrong, the people who care are notified right away — with enough context to know whether to call or come over.
Pebble is guided by a multidisciplinary panel of researchers and clinicians helping us advance the science of fall detection and physical therapy — not just the engineering of it.
Dr. Tomita is advising informally on how Pebble distinguishes real falls from everyday movement, and is helping guide the project's IRB submission and research design as it moves toward a formal study.
They're joined by a growing panel of researchers and scientists across rehabilitation medicine, biomedical engineering, and physical therapy — helping keep Pebble honest to the science, not just the story.
