Depending on what you want as "important details", 1640 once rigged up a set of LEDs to the sides of our driver's safety glasses and used vision processing to program light codes. It only works for information that your vision processing can handle and that's simply enough to convey in blinking lights, but it can be useful some years. There might even be a way to rig up a more complicated LED configuration as knockoff HUD goggles.
