Apple is probably releasing their VR/AR product this year, which means they're probably going to patent a *bunch* of stuff which is wildly obvious but just coincidentally has never been shipped before. So it's occurring to me it is a good idea to start publicly documenting various "hey, you know what would be a good idea to do in VR" ideas, so we can point to it as prior art when the lawsuit happens.
Some things I've been thinking about for years:
1. If you have AR, it would be really cool to do walking street directions that actually superimpose a red path line, floating arrows etc on the real world.
2. It would be cool to do a "teleconference" in AR sitting at a table with the person you're teleconferencing with superimposed into another chair. (My brother and I have discussed this idea before.)
3. The Hololens can pop up Win10 Metro windows that you touch with your finger to activate touch buttons. What I *really* want is for an AR headset to create actual *monitors*, IE, I have no monitor on my desk but I can spawn as many fake ones as I want floating above it. I would control these with a keyboard and a mouse sitting on the desk, and would have a mouse cursor I would move between like multiple monitors. I would use touch only to touch/grab and move the fake screens around.
(It would be very fun to have a half-laptop computer, with no screen, just the keyboard and trackpad bits, with all the screens provided by AR glasses.)
