"Most companies would get a stage, and we'd have lights and music and everything else," joked Andy Rubin as he addressed a group of reporters. He was casually dressed in jeans and a blue T-shirt with a coffee mug in one hand as he stood in a lobby-like room. The setup was located just a few feet from an adult-size slide and overlooked a farm of cubicles on one side and a cafeteria on the other. But a product launch it was. We were gathered at Playground Global -- a startup incubator that Rubin founded after he left Google -- for the unveiling of what is perhaps his most important creation since Android.

Over the last 24 hours, you might have missed electronic glasses that auto-focus for you, Google's $4 million contribution to immigration organizations, and Gap's augmented reality dressing room app. An infrared distance meter adjusts the malleable lenses in just 14 milliseconds. They're not pretty, but prototype eyeglasses from University of Utah scientists could make progressive lenses obsolete for older people. Using electronically-activated lenses and infrared distance meters, they can focus automatically on whatever you're looking at, whether it's far or close up. Once perfected, the device could eliminate the need for multiple pairs of reading or driving glasses for folks with presbyopia or farsightedness.
