Mattias Andersson, an interaction designer for Swedish agency Ocean Observations at the time, came to MEX in December 2010 to give a ground breaking presentation on the role of 3D in mobile user experience. It was a time when 3D televisions were emerging strongly and the first mobile displays which could project 3D without the need for special glasses were emerging. Mattias’ practical and in-depth session highlighted the difference between 3D and visual depth, and brought a refreshing dose of reality to how consumers actually perceive depth and perspective.
