Toilets and toilet habits are perceived as a taboo subject that people may be reluctant or embarrassed to talk openly about. In the past, appropriately designed Computer Based Interviews have been shown to encourage more honest answers to sensitive questions than other forms of interview, and can be more interesting and engaging that filling out a paper questionnaire. This chapter presents Dundee University's role within the Friendly Restroom project which was primarily to provide Computer Based Interviews and other computer-based requirements gathering tools to be used to elicit toileting requirements of elderly people. Dundee University also investigated the feasibility of using Virtual Reality technologies, such as 3D environments and 360 degree panoramas, to support this information and requirements gathering.
