15 year old Kenneth Shinozuka lives in New York City with his parents, aunt and grandfather. He’s one smart kid.

Kenneth’s grandfather suffers from Alzheimer’s and tended to wander out of their apartment at night, getting out in the streets of New York City, causing a number of accidents, not to mention a lot of worry.

Kenneth’s solution won him one of the 15 finalist slots at the 2014 Google Science Fair. Watch the video. Incredible work.
