Lindsay Perry posed this question at the ACAA/UD conference held in Melbourne October 2015. In this presentation she provides examples that relate to the classic seven principles of universal design. The second part of her presentation contains a quick survey of friends, family and work colleagues. She asked them, “When you go out for the day, what is the main thing you rely on to be able to travel through and navigate the built environment? What irritates you?” The responses all relate to wayfinding – knowing where you are and having signs that make sense. Download the PDF of the presentation here.
