The KDDI Mi-Look comes from Japanese telecommunications company Au and is a device that acts as an interactive monitor for senior citizens. It's GPS-capable, which means you'll be able to find out where Grandpa and Grandma are at all times. There's an activated strap with a buzzer that will let you know whether they have fallen or been in an accident that could prevent them from moving comfortably.
This nifty little gadget also emails listed relatives and lets them know of the person's whereabouts at all times as well. The KDDI Mi-Look GPS device may seem a little much for some families, but do keep in mind that this is targeted towards the elderly with memory loss and Alzheimer's disease.
