The glove vibrates when you "feel" an object in 3d space. You can grab items and move them wherever you want.
Unfortunately, the movie was a major disappointment but I can't have a blog like this and NOT add a link to this magnificent David 8 teaser – a great riff on the android legacy. I'll save my film critique for another day.
IBM Think! was an exhibit / interactive experience staged in an underground parking garage at Lincoln Center in NYC. The entrance ramp was flanked by a huge LED wall which streamed a mix of prepared video and real time data (pollution index, traffic data etc). Inside the exhibit were large vertical LCD panels and mirrored walls which transformed the space into an immersive presentation that surrounded the audience with choreographed sound, video and text. When the video presentation ended the screens essentially turned into large interactive iPad-like devices which the exhibit-goers used to explore content. This was a very well crafted exhibit full of useful information and technology.
