Stefan Geens in Stockholm, editor of the Ogle Earth blog, brings you news about virtual globes, with a special focus on Google Earth. Recently he showcased this video demonstration of Perceptive Pixel's display technology.
Han began his presentation. His fingertips splayed, he placed them on the cobalt blue 36-inch-wide display before him and traced playful, wavy lines that were projected onto a giant screen at his back. He conjured up a lava lamp and sculpted floating blobs that changed color and shape based on how hard he pressed. ("Google should have something like this in their lobby," he joked.) With the crowd beginning to stir, he called up some vacation photos, manipulating them on the monitor as if they were actual prints on a tabletop. He expanded and shrank each image by pulling his two index fingers apart or bringing them together. A few oohs and aahs bubbled up from the floor.
Suppressing a smile, Han told the assembled brain trust that he rejects the idea that "we are going to introduce a whole new generation of people to computing with the standard keyboard, mouse, and Windows pointer interface." Scattering and collecting photos like so many playing cards, he added, "This is really the way we should be interacting with the machines." Applause rippled through the room. Someone whistled. Han began to feel a little bigger.
But he was far from finished. Han pulled up a two-dimensional keyboard that floated slowly across the screen. "There is no reason in this day and age that we should be conforming to a physical device," he said. "These interfaces should start conforming to us." He tapped the screen to produce dozens of fuzzy white balls, which bounced around a playing field he defined with a wave of the hand. A flick of a finger pulled down a mountainous landscape derived from satellite data, and Han began flying through it, using his fingertips to swoop down from a global perspective to a continental one, until finally he was zipping through narrow slot canyons like someone on an Xbox. He rotated his hands like a clock's, tilting the entire field of view on its axis--an F16 in a barrel roll. He ended his nine-minute presentation by drawing a puppet, which he made dance with two fingers.
He basked in the rock-star applause. This is the best kind of affirmation, he thought. The moment you live for.
