We’ve been pitching in personal views in the agency, for the question ‘what’s exciting right now’ – related to digital marketing / technology / platforms …. etc.
Some of those coming back from my work mates are ‘oh, I didn’t know that’ for me, which is cool.
So more checking out of some new things for me this weekend 
Here are my current ‘what’s exciting’ developments, in no particular order:
1. “Watson, you have control” could just be four very prophetic words for the near future.
Watson is an natural language querying system / artificial intelligence engine created by IBM.
It was recently pitted against humans in the USA Jeopardy! game show. And did really really well.
And then (it’s still a baby in AI terms so is learning) also really badly. No doubt that will change soon and the implications for HCI and Search technology will be massive.

2. Another fast developing area of Human Computer Interaction is that of interface control. Goodbye Mouse, Hello Hands.
Here’s a talk John Underkoffler did at TED earlier this year – now input devices are … us.
No need for a physical mediating mouse or keyboard. And no need for a touch screen in the future (depending on the environment / context).

And here’s gesture interface at play with the Microsoft Kinect technology and XBox 360 :
3. Augmented Reality
I haven’t caught up with what’s new with AR in the last few weeks but I did spot this , what looks to be a useful application for Wimbledon.
I also heard that there’s an AR app for Glastonbury, though not sure you want to spinning your iphone around in the mud / squashed by thousands of others / stoned out your box / drunk on cider …

Mark, just wanted to say what a cool writeup. I’ll check out those videos.
Thanks for the feedback Brent, that’s good to hear!
