This chapter describes the five different generations of toilet prototypes which have been installed and tested in a laboratory environment in Vienna during FRR (Friendly Rest Room) project. It outlines the data measured during tests with older and disabled persons and their care persons. The FRR prototypes have been equipped with a PC based control unit, voice input and output, contactless smart card technology and several sensors for estimating the user's intention and for recognizing potential falls of the user in the toilet area. The toilet components have shown to be very useful for disabled and older persons during extensive tests in a laboratory setting.
