To be fair, it looks like all the demos that show a person actually wearing the glasses have slightly translucent objects. While it is technically impossible to occlude an object 100% with this technology, I believe the percieved opacity of the augmented reality object is based on the difference between the intensity of the projected image and the real world background.
Theoretically, it should be possible to overpower the background light and have an object appear to be totally opaque, which is similar to the principle behind one-way mirrors. That amount of light might be blinding in certain circumstances, though.
- modeless 13y agoTheoretically you could render occluding white objects that are strictly brighter than anything in the real scene by overpowering the background light. Dark objects, shadows, or strongly colored objects could not be rendered in this way, as they require blocking incoming light of the wrong brightness or color. In practice, overpowering background light is not possible with current displays. They're simply not bright enough.
- v13inc 13y agoThat is a really good point. I seem to remember a really interesting article posted to HN awhile ago that went over all the pitfalls in depth. I'm really wishing I had bookmarked it now. I think I'm going to have to rewatch the promo video in depth to see if they have any unrealistic demos with glasses-wearing users. I still believe this technology would be really useful for doing Real Work. You could get around the shadow problem by working in a black surface. I am imagining an interface with a black drafting desk, small bluetooth keyboard, and a 3d tracked pen with this AR display could be absolutely revolutionary for certain engineering disciplines.
