Asteroid Storm is an interactive 3D game coming to UK theaters later this summer that will precede movies like Ice Age 3 3D and Toy Story 3D.
20 UK Vue cinemas will offer audiences the opportunity to steer a spaceship through an asteroid belt. Two IR cameras will track the audience (the left half raises their hands to veer left, the right half raises their hands to veer right). None of the experience is prerendered—it's all an interactive video game.
As films go 3D, it'll be interesting to see if theaters (and movie makers) take the opportunity to integrate more interactive elements to the experience. Raising my hand in the air, however, is not how I see myself defeating the Decepticons to rule the Universe. [Register Hardware]
