Smart House

In the Dworsky home, every time Bill or Dorthy, both 80 years old, opens the refrigerator, closes the bathroom door or lifts the lid on a pill container, tiny sensors make notes on a digital logbook.

Phil, their son, checks it daily on his smartphone. If there is no activity within a designated time span, Phil receives an email. "This is peace of mind, really," he says.

I read an article that suggested within the next few years a home will contain upwards of a thousand internet connections - small inexpensive sensors creating a "Smart House."

What part of your house would you like to keep track of?
