Jim Kosem’s December 2011 MEX Session looks at sensitive and challenging subject matter, discussing a digital experience project designed to help Slovenian school children learn about the history of war crimes in their country. Kosem explains how his team dealt with these sensitive issues and built a service accessible to all using basic telephony and audible interactions, allowing the technology to fade into the background. It is a lesson in how non-visual UIs can focus participants on the importance of the subject matter and the physical location of the experience.
