13-Year-Old Develops AI Fall-Detecting Mobile App
Kevin Tang, a 13-year-old, won the 2025 3M Young Scientist Challenge for FallGuard, an AI camera-based system that detects falls and alerts caregivers. He launched a free FallGuard app after using his $25,000 prize to develop a MacBook-based version capable of converting a regular computer into the monitoring device. The system uses MediaPipe and a two-stage algorithm, with privacy protections and current single-camera limits.
Key Points
- 1Created FallGuard, an AI camera-based system detecting falls and extended lay-down events in real time
- 2Uses MediaPipe and a two-stage posture-and-velocity algorithm to reduce false positives and protect privacy
- 3Enables instant alerts to multiple caregivers via app; current single-computer support limits whole-home coverage
Scoring Rationale
Practical, verifiable prototype with 3M award recognition; limited novelty and small-scale, single-camera deployment constrains broader industry impact.
