During this year’s VisWeek (truly great conferences, I must say), some friends expressed interests in my work on theoretical / cognitive approaches to InfoVis. They complained however that my papers were no easy read - which was a bit surprising to me. I’ve tried very hard to make the arguments understandable, and you would believe me if you saw earlier drafts of my papers. Ji Soo suggested that I should start blogging about the relevant topics and materials at introductory levels, and I think it’s a great idea. So in the future I’ll periodically post something about papers/books that have influenced my thinking, important theoretical concepts and questions, and my own take on cognitive issues in InfoVis. I’m by no means an authority in these areas - in fact when I’m talking about some of the related theories and work I’ll probably offer inaccurate interpretations. But I hope that this blog will be the starting point for lively and continuous discussions on cognition, visualization, analytics and interaction. Stay tuned!
