NonSlip was designed to monitor and prevent falls of the elderly who are home alone. A working prototype was created during a 24 hours IoT marathon. The interface was designed to easily showcase the multitude of sensors that were used. It allows us to see the pressure a person was putting on the slippers, a 3d model of how the slippers are moving or rotating in real-time. We used existing bluetooth devices in the house to triangulate a person's location.
