3D interfaces are generally a bad idea and usually impede user experience rather than improve it, but since the 3D implementation on this cell phone UI is minimal, I think it really does bring an interesting touch to it.

The concept, which gives traditionally flat interface elements a very convincing sense of depth and layering, relies on eyetracking and TAT’s in-house 3D engine, which renders in real time in the video. This isn’t your dad’s eyetracking, which analyzes your eyeballs for control cues—no, it really just uses your eyes’ locations, along with the orientation of the device, as part of the perspective equation that creates a convincing 3D effect.
