Earlier quoted context omitted.

Nor is there with holograms. Holography requires creation of light fields from a flat surface - each point on the surface reflects a different amount of light depending on what angle it is viewed from, exactly mimicking the way light would pass through that plane if an object were there. No 'projection of light into space' is involved. Since images are formed on your retina by focusing real lightfields, a true hologr…

I don't know enough about holography to agree or disagree, I was under the impression that the "lightfield" has a 3D structure that e.g. the light coming from a movie screen doesn't. In any event I don't think that the "holographic" goggles are actually projecting a complete lightfield. I'm pretty sure they just shine two more-or-less normal images into your eyes although the math to compute those images might, uh, b…

You can capture a lightfield using a 2d sensor https://www.lytro.com/ It's like the way your eye can re-focus on different distances without moving. That's something you can't do with MS's new tech - everything in the image will be in focus at the same distance, even if your eyes are getting different images.

What is the killer app that will get people to go out and buy these? I don't think Holo Studio is it. Where is your imagination racing to?

Virtual hangout--do things with friends even if they're all over the world. It would also be extremely useful for remote work.

You could see their faces, if they're in front of webcams, but they couldn't see your face (because you'll be wearing these.)

What sort of use case is this for? The demos talked about in the article seem rather specific. I don't see how this will appeal to mass consumers.

The tech is cool. The UI as described is for campy unergonomic noobs, only. "he is trying to see Project HoloLens as if for the first time" This is a rather significant problem when talking about the real world as per the article. Consider the electrician discussion in the article. Real electricians want / need / expect real tools, not noob friendly fisher price toys. Its a tool for camp. As wikipedia says "based on…

Think long-term... better voice interfaces, brain-computer interface.

This isn't the end-game. It's going to be slightly weird, but the potential is there.

With the camera, it's easy to understand how they make the objects feel solid - they just overlay it over the video feed. How would that work on the glasses, I have no idea. Does it have LCD shutters that block incoming light where they want to add a "solid" object?

"I sculpt a virtual toy (a fluorescent green snowman) that I can then produce with a 3-D printer." This sounds amazing! She didn't go into a ton of details on this, so I wonder if it's as cool as I imagine. If done well it could be a game changer for 3D printing (and a "killer app" for many families).

They designed and printed a working quad copter. So there's that.

Here is the product website with three promo videos on it: http://www.microsoft.com/microsoft-hololens/en-us

Makes me think of something i read about from CES.

Basically a helmet of sorts where you dropped a smartphone into a slot at the top, and some semi-transparent lenses in front of wearer's eyes then made the phone screen appear to float in front of said wearer.

Edit: found an article about it: http://www.pocket-lint.com/news/132280-seer-the-augmented-re...

It looks impressive, but it would help to be able to tell the hype from reality: "Sensors flood the device with terabytes of data every second" ... somehow I doubt the aggregate bandwidth of the device is > 1TB\s Makes it harder to know how much of the rest of the 'explanations' are accurate.

Could the sensors be indeed flooding the device with terabytes of data, but the device can only sample that data at a more reasonable rate?

I think Microsoft re-branding Augmented reality as "holographic" is hugely impactful and, with the new wave of AR and CV products that are coming onto the market [1] might be the thing that makes people take it seriously.

It's just so much easier to explain to people what it is if you say Holographic vs Augmented Reality - even though it is technically wrong. Kudos to MSFT for making that leap.
