Minority Report was an enjoyable action flick, but it may hold the blame for getting the idea stuck in our collective heads that 3D gesture control is the next frontier for computing. The Kinect from Microsoft helped further this idea around as well, with a pretty good (though highly limited regarding needed space, applications, etc.) gesture experience. But a lot of startups and other companies are chasing this carrot – and it begs the question of whether there’s even a carrot to chase.
