Is the image from glass projected into your eye or onto a screen? If it's projected directly into your eye then wouldn't it possible to set the focal distance to be roughly the same as where you're already looking?
NB given I have never ever heard of this happening i suspect there's a hole in my knowledge of optics but it would be awesome if it was possible.
- DanBC 13y agoThere are some "virtual retinal displays", but they're mostly vapourware rather than actively developed and sold devices. They use a laser beam into the eye. (http://www.hitl.washington.edu/projects/vrd/ http://www.hitl.washington.edu/projects/vrd/) (http://ascentlookout.atos.net/en-us/enabling_information_technologies/virtual_retinal_display/default.htm http://ascentlookout.atos.net/en-us/enabling_information_tec...) (http://eclecti.cc/hardware/blinded-by-the-light-diy-retinal-projection http://eclecti.cc/hardware/blinded-by-the-light-diy-retinal-...) That last link is a DIY (terrifying) project. Your eyes, your choice. Retinas are delicate. EDIT: One company doing stuff is "Microvision" - (http://www.microvision.com/index2.html http://www.microvision.com/index2.html) but they've changed to pico-projectors.
