The Problem

• Falls in bathrooms and bedrooms are common and time-sensitive, but often unseen until it is too late.
• Wearables are often not worn during showers.
• Traditional cameras create major privacy concerns in private spaces.
• The presentation cites CDC data that roughly 80% of bathroom injuries are caused by falls.

Prototype: Lumisafe

• End-to-end encrypted device for fall risk alerts.
• Time-of-Flight distance sensors that only capture room depth.
• Edge AI that improves locally with personalized environments.
• Data is processed on-device all the time.
• Simple app workflow for caregivers and families.

The Solution

SafeSteps OC is a community deployment initiative focused on timely fall detection. The team installs Lumisafe in homes with seniors who live alone and pairs installation with prevention-focused training.

Caretakers can receive alerts and provide check-ins around the clock, helping people stay safer without giving up privacy.

Privacy and Trust

• No video is collected.
• Sensor information is processed locally at all times.
• Edge AI inference stays on-device.
• Alerts trigger only for high-confidence events.
