QUICK ONES are bigger than a tweet... but not much!
I finally saw The Avengers this week and enjoyed the concepts of all the 3D interfaces that they use in that universe. In this article, "MIT Creates Amazing UI From Levitating Orbs", we see how MIT is exploring how 3D spacial interfaces might actually work. Grabbing space with your imagination is cool and all that, but it seems like it would be very difficult to do well. I know that in the console driving games I've always struggled with the fact that I can't feel what the car is doing. (I'd never noticed that many of my driving decisions about things like speed an braking are made based on how things feel more than how they look.) In the same way, a rich 3D experience with no tactile component is going to be harder for many people to use.
MIT's work is looking to add a physical component by letting you move around an orb that is floating in space. It's crude for the moment, but these things always are when they start. I'm very intrigued to see which what this goes. It could be very interesting.
