In early March I had two keynote talks at academic symposiums scheduled back to back.
March 4, 2012 I gave a keynote address at IEEE Symposium on 3D User Interfaces. It was nice to talk there. I was one of the early folks in the middle of 90s who formulated the 3DUI as a proper research field, did my Ph.D. on this topic and co-authored a book which is still the only proper academic reference on 3D UI. I was quite impressed that there was a significant number of people attending the symposium, so there interest in the field is stable.
The next day on March 5th, 2012 I was talking at Special Session on Human Computer Interaction at Haptic Symposium 2012 in Vancouver. The other two speakers were Desney Tan from Microsoft Research and Patrick Baudisch from University of Potstdam, Germany. It was a great, very exciting session.
