She sleeps most of the time now BUT. That also means she gets up and wonders around at all hours. Makes it a little difficult for me to concentrate on work and or sleep.

So far, found MIT just announced a new technology using low power radio transmitter and 3 receivers to track 3D movement through walls accurately enough a person can point at a light and turn it on/off and has a 96% accuracy telling if they fall down. Currently it can only track one person and loses them if they stop moving.

I'm thinking combine this with current IR heat/motion sensors and you got a very viable product for keeping track of anyone in your home, not only for monitoring like mom, but working with home automation.
