The English company Light Blue Optics boasts one of the biggest ideas at this year's CES. The company is debuting a projection system that throws an image of a fully functional keyboard on any table or flat surface. The outfit claims its new technology, which uses holographic lasers to capture typing strokes and hand movements, will be close enough to a real keyboard to type well.

But many questions loom: Projectable keyboards have been in commercial deployment since the turn of the millennium, and with limited success.
