We're always interested in wearables that go beyond just telling you how many steps you've walked in a day. CarePredict, for instance, is building a smartwatch that's designed to monitor the elderly while maintaining their independence. The Tempo is a wrist-worn sensor that keeps an eye on someone's activity patterns, and should it spot an anomaly, raise the alarm. It works by mapping out a general schedule of the day, and observing changes like an unusual mid-day nap or if someone has remained still in one room for too long. It'll even observe trends over a much longer period of time, so if someone's walking pace slows over a couple of weeks, you'll be able to see it and address any underlying issues.
