The Atongm Laser Keyboard projects a virtual laser keyboard on to a flat surface, supposedly letting you type like you normally would. Projection keyboards aren't exactly new -- there have been similar devices on the market since 2002 -- but you would figure that in the intervening 12 years, technology would have been improved to the point where such virtual keyboards are the norm. Unfortunately, this isn't the case with Atongm's device.
