Various studies have been conducted for developing interaction techniques in a smart house. Some of our previous studies [1, 2] focused on bathrooms and we converted an existing normal bathtub system into a user interface by using embedded sensors. A system called Bathcratch [2] detects squeak sounds by rubbing on a bathtub edge. To generate squeaks, it(More)
We present RapTapBath: a human-computer interface system that converts an existing bathtub into a controller that recognizes hand-tapped tones and patterns on a bathtub's edge. This system utilizes embedded piezoelectric sensors in the bathtub's edge to analyze acoustic signals of tapped sounds, and projects a menu on the tub's edge using a projector(More)
