wjcofkc writes "Interactive displays projected into the air in the spirit of Iron Man have been heralded as the next step in visual technology. Yet many obstacles remain. According to Russian designer Max Kamanin, creator of Displair, many the problems have now been largely cracked. With this attempt at refining the technology, the image is created inside a layer of dry fog which is composed of ultra-fine water droplets so small they lack moisture. Three-dimensional projections are then created using infrared sensors. The projected screen currently responds intuitively to 1,500 hand movements, many of which are similar to those used on mobile devices, such as pinch and zoom. The most immediate applications include advertising and medicine, with the latter offering a more hygienic alternative to touchscreens. The most immediate objection from home and office computer users is that they don't want to be waving their hands around all day, and while such questions as 'What happens when I turn on a fan?' are not answered here, just imagine a future with a projected keyboard and trackpad that use puff-air haptic feedback with the option of reaching right into the screen whenever it applies to the application at hand — and applications that take advantage of such a technology would no doubt come along. Better yet, imagine for yourself in the comments. As always, pictures speak a thousand words, so don't neglect the articles gallery."
