I would love one of these. If I get accepted into my research program, I'm going to be looking at some clunky gloves and a lot of laptop time.
So, a scalable projectable keyboard + laptop combo would be absolutely amazing in a lab setting. (I've already looked into those projected keyboards too)
That's an interesting application I never thought of. Typically I thought about these as being harder to use do to the lack of tactile feedback. But in environments where you have no tactile feedback anyways, something like this would be great: service workers who work outdoors in the cold, astronauts, lab techs, soldiers, etc.
