A Child is Saved: Faith in Humanity is Restored

A Child is Saved: Faith in Humanity is Restored

Children of Men presents the dark vision of a totalitarian world ravished by war, paranoia and the frustrations of man. The world’s youngest citizen has just died at 18, and with female fertility becoming obsolete, man cannot reproduce. No child has been born on the face of the planet for eighteen years. Man, and his future, is dying.

However, the unexpected discovery of a lone pregnant woman represents the miracle that can change the course of humanity. The discovery launches a desperate, perilous journey to deliver the woman and her child to safety, restoring faith in a future for humans beyond those presently on earth.

The Emergence of Multi-Touch Technology

When Steve Jobs first introduced Apple’s iPhone at Macworld last year, the feature that evoked the most excitement was its touch-screen interface, allowing more than one touch at a time. The multi-touch technology added innovative new functions, such as allowing the user to easily zoom in and out of pictures and web pages by pinching the screen with two fingers.

But a more advanced version of the amazing power of multi-touch technology has been unleashed upon screens much larger than those on the iPhones. Over the past few years, Jeff Han, a research scientist at New York University, has developed a relatively inexpensive way to make large multi-touch screens that can accommodate 10, 20, or even more fingers. He foresees applications that range from interactive whiteboards to touch-screen tables and digital walls, any of which can manipulated by more than just one person. Han’s company, Perspective Pixel, is based upon the unique multi-touch technology that he’s pioneered.

The Amazing Perspective Pixel

Han’s touch display is made of clear acrylic with light-emitting diodes that are attached to the edges, which illuminate a six-millimeter-thick acrylic piece with infrared light. Normally, the light from the diodes reflects along predictable paths within the acrylic plate, a physical phenomenon called total internal reflection. However, once a finger or other object touches the acrylic, the internally reflecting light diffuses at the point of contact, scattering outside the surface. Behind the acrylic surface, there is a camera that captures this light and using simple image-processing software, the captured scattering is interpreted in real time as discrete touches and strokes.

Many researchers who’ve been working for decades on touch technology have been extremely excited to see these developments. “For almost two decades, we’ve been trapped by the tyranny of the screen, the mouse, and the keyboard,” observed Don Norman, professor at Northwestern University, in Chicago, and the author of The Design of Future Things. “It’s nice to think we’re breaking away from that and going toward touch-screen manipulation in the real physical world.”

What follows below is a video that presents a fascinating demonstration of Han’s Pespective Pixel, an exhibition that he made of “Perspective Pixel” at the annual TED Conference in Aspen, Colorado.
