For those building a house from the ground-up, installing a slew of cameras and touch panels
to automate it may not be all that burdensome, but new research is hoping to use electrical noise to enable current homeowners to reap the benefits of home automation
without tearing the walls back down. Put simply, the new technology would recognize noise whenever a denizen flipped on / off a household appliance, thus enabling the house to react by automatically switching on lights, heat, or music in that very room. 'Course, even the creators realize that it has limitations in its current state, namely that the house won't even flinch if you enter a room but don't interact with an appliance.
