I've been wearing a little technology that we call Shimmer.

But when we look at these cycles of data over a longer period of time and we're looking at everything from motion around different rooms in the house, to sort of micro motions that Shimmer picks up, about gait and stride length these streams of data are starting to tell us things about behavioral patterns that we've never understood before.

But with something like Shimmer, or we have something called the Magic Carpet, embedded sensors in carpet, or camera based systems that we borrowed from sports medicine, we're starting for the first time in those 600 elderly households to collect actual kinematic motion data to understand What are the subtle changes that are occurring that can show us that mom has become risk at falls?
