The Iron Man 2 movie had several enticing scenes of the main character interacting with his computer.

When Stark is mid-design and doesn’t like what he’s working on, he grabs it off the projection and throws it into the trash. This allows him to throw away a virtual idea with as much expression as can be used with an idea that’s taken physical form.

At one point, he performs a 3-D scan of a physical model because he wants to create a version that he can manipulate easily. He lifts a projected image off the physical object and becomes able to spin it, change its size, and alter it with flicks of the hand.

What makes the interface look most attractive is how physically involved Stark becomes in design. With the power of voice and gesture combined, Stark is able to give small, quiet commands when contemplative, and become more expansive and hands-on when excited. The vision of a computing device that’s able to adapt so smoothly to the user’s mood and circumstance is compelling to say the least.
