I subscribe to the TED Talks podcast feed and I've seen some really great presenters covering a very wide range of topics. As Apple's Steve Jobs released the iPhone at Macworld earlier this week I thought back to one of TED's most impressive presenters as it related to applicable technology. That presentation was done by NYU researcher Jeff Han and multi-touch interaction.
Chris Anderson, TED's founder, thought the same and asked Jeff what his thoughts were. I agree with Jeff and I'd predict we see larger versions of multi-touch screens within the next couple of years. It's really fascinating and intuitive.
