[citation][nom]rcwp116[/nom]I just have this dumb idea (I guess)... Would it possible to have a gadget like a spectacle, when you are looking at your PC/Notebook device it will show the monitor screen, and if you are looking away from your device.. it will switch to normal spectacles.. In this way, you won't have to worry about what size of monitor screen to choose.. and you will have a more private space without nosey people wondering what you are typing.. Anyways.. just my 2 cents..[/citation]
Not dumb; it could theoretically work. Think DLP but with a color laser-like LED array as opposed to a spinning color wheel, and many cleverly positioned micro-mirrors and ceramic optic lenses. Then, a sensor looks for key-coded position tags on the glasses to calculate projection direction, orientation, and focal distance, as well as to determine when the user is looking away so as to shut off the monitor when not in use.
The likely problems would be complexity, response time, projected image resolution/clarity, color range/accuracy, overall fragility, bulk (think the size of, say, two decks of playing cards stacked when the technology has matured, as the unit would not likely be able to be manufactured flat), cost, and energy efficiency, all of which are reasons DLP TV's are on the way out.
