"When a motion sensor detects a visitor in the hallway outside, toilet picks from a list of sounds to play to encourage a visitor to enter. If toilet has a visitor, it plays appropriate sounds based on state from the seat positions, the laser beam across the seat being broken, the light switch being off, etc. It scrolls news headlines across the LCD panel. When the toilet is flushed, the lights flash and the music fades. If the seat is left up when the door is opened, a reminder sound plays. Toilet also serves web pages to the outside that allow us to view history from the database, request specific CD tracks, control the volume, and send messages to the LCD screen."
