Joshua Trathen is studying Sustainable Product Design at Falmouth University. For his final year project he is looking to develop a navigation product which uses echo location to warn visually impaired users of potential hazards when they are out and about.

As part of his research, Joshua wants to find out what products visually impaired and blind audiences currently use to navigate exterior environments and what their experience has been.

So if you use a symbol cane, navigation apps or any other navigation products and would be happy to share your experience with Joshua, please contact him on 07470 133112 or e-mail joshtrathen@googlemail.com.
