This is interesting its a TV that turns itself off when no one is watching it. The new Sony Bravia WE5 Eco TV includes something called a smart presence sensor that will turn the TV off if it no longer detects any movement in the room. The TV detects the movement and body heat of anyone sitting within range of the screen. If the viewer falls asleep or leaves the room the sensor can detect this and switched the picture mode off reducing the power consumption. The set then remains idle for 30 minutes before switching itself off completely. It’s an interesting idea, but I wonder how well it copes with people who sit still for long periods of time and also how it deals with pets moving about the house.
