Over 12M older Americans live alone, many frail or chronically ill. They value independence while their adult children crave safety for their parent. Wearables and cameras are intrusive, inconvenient, and often rejected. Atlas5D uses tablet devices to quantify how someone moves at home while preserving privacy and dignity, and alerts family (and call center in future) if there is a change or potential issue. Atlas5D is currently in private beta with paying customers and has already saved a life.
