Today's word is "AUTOSTEREOSCOPY", or, in plain English, glasses-free 3D. Sure, these sci-fi screens exist today, but because they work by directing particular pixels to particular ocular vantage points, stepping a few inches outside a sweet spot can transform that fourth-wall-breaking Na'vi into a blue blur. This is why the tech is, thus far, found mostly on handheld gadgets such as the Nintendo 3DS-users keep a constant grip on the screen and can control the viewing angle for optimal 3D joy.
But that could soon change. Toshiba recently showed a technology that make we believe we could lead the way to larger and more usable autostereoscopic displays. Using a laptop webcam to track a user's eyes, the company built a PC with a 3D screen that can dynamically adjust to provide naked-eye viewing from any angle. The result is a far greater freedom of mobility-and visual clarity-than is provided by current glasses-free 3D screens.
The tech now limits viewing to a single user on a laptop screen, but we can easily see how it could be adapted for large-screen viewing by multiple people. Consider: The cameras embedded in the Microsoft Kinect sensor bar can simultaneously track subtle movements by more than one person. In other words, they collect enough data to possibly allow a glasses-free 3D TV to accommodate multiple people at multiple sweet spots. Of course, neither Microsoft nor Toshiba has made any indication that it is working on this. so, hackers, get busy-the ultimate Super Bowl party is within your grasp.
