a lot of people as they get older their vestibular function diminishes and they can't tell when they're tilting they can't tell when they're off axis and the problem is then they end up falling and they break a hip and they end up in the hospital and then things go downhill so um we just we built a little um you know a n axis uh motion detector and IMU and we can tell where they are axis wise and and when they're tilted we just tell them and they feel it on their wrist
