Ok - it seems that they 'absolutely' have something bewildering, and eye-popping. There are enough 'no information' testimonials by smart people to get that. BUT I'm still pretty weary of billions getting pumped into a business that remains unproven. + Maybe development is very expensive + Maybe the goggles cost to much + Maybe they just don't have quite enough content to justify the high costs + Maybe the experience…

I was struck by the careful phrasing in the article and didn't want to dog pile on it at first - I note other reasons elsewhere why I'm rather dubious - but here's the line: > The centerpiece of Magic Leap’s technology is a head-mounted display, but the final product should fit into a pair of spectacles. When you’re wearing the device, it doesn’t block your view of the world; the hardware projects an image directly o…

>the hardware projects an image directly onto your retina through an optics system built into a piece of semitransparent glass

Isn't this exactly how every display works? Possibly sans glass even...

Uncompressed 8K over the public internet!

Why uncompressed? Recent mobile devices have hardware video decoding.

There are plenty of devices without HEVC hardware decode, though, which is basically a prerequisite to 4K. And software decoding is god-awful for anything besides South Park.

(It's not actually required, but the efficiency loss between H.264 and HEVC for 4K is pretty massive.)

I was also disappointed by that statement. I would expect much more from the first applications. Let me try to be constructive and think of some: + To have a cat even if you can't feed it or clean up (elderly). + To find out how it is to have a baby, how to feed it, how to care for it. + Dating first with an avatar before going for the real deal. + Searching for things without having to open cabinets or boxes. + Colo…

All I really need personally is glasses that can show me text when I look at someone reminding me what their name is. That Terminator tech - seamless glasses that let you assign and view little annotations on things.

Depends on size of occluded area? If I block the sun with my thumb, some light does go around, but it's still a decently effective mask.

If you hold out your thumb between your eye and the sun, such that your thumb appears to just block the edges of the sun, then you will be effectively blocking the entire set of overlapping wavefronts emanating from the sun (that would have formed multiple "pixels" forming the sun image on your retina), preventing their arrival at your cornea and ultimately entering your pupil. Notice that your thumb is about about 1…

Thanks for the paper link. Is there a plausible way to use destructive interference to create true black? I remember patents around this.

I believe Magic Leap has a new kind of display technology, but the article is pretty bullshit-sounding with statements like this: "Throw out your PC, your laptop and your mobile phone, because the computing power you need will be in your glasses, and they can make a display appear anywhere, at any size you like." Yeah sure, they not only made a new display tech but integrated the computing power of desktops or laptop…

I question how much resolution they have. How is the text rendering?

Their initial design was a fiber projector that oscillated in a spiral pattern with something like 512 rings (I can't remember the exact number). Along the the spiral you can have any resolution, only limited by how fast you can modulate the laser. Details along the spiral would be sharp, anything along the normal (spokes radiating inwards) would be only have 1024 distinct levels of detail.

But their later patents showed whole arrays of these fiber projectors. They are probably limited by the optics in-between the fiber and the eye and by the display controller bandwidth more than anything.

I don't want to live in a world with many of those features. I don't want my pets to talk to me, have my plants tell me they're thirsty, or go on a date with an avatar. And, as a parent of a two-year-old, trust me, no sort of application can let you find out how it is to have a baby. Maybe I'm just weird or old-fashioned.

I voted him up because I want to see that movie, but I agree with you, in that I don't want to live that life.

i'm hoping its real... but all that time and all the hype with no substance is confidence shaking. i mean, why would you not allay the obvious fears of investors and potential customers?

there are also the deep technical problems which are widely acknowledged in the field and clearly not addressed. a top spec desktop machine struggles to keep up with your eyes movements /if they are known in advance/ - the idea that a pear of glasses coupled with /any/ peripheral, even one the size of your house, can contain the hardware to do this in real-time is quite far-fetched - even accounting for sensors with feedback and clever mechanical tricks.

there is no mention of how to deal with occlusion. no amount of throwing light at your retina can solve that problem... you need something to intelligently block it out. the marketing hype images make this seem like a solved problem...

maybe there is something that works, but i have no faith that magic leap is anything more than a scam targetting VCs. the same opinion i have grudgingly kept since i first saw anything of it... because its a cool idea and i want it.

i hope these issues are publicly addressed so i can buy it early in confidence instead of waiting to see if its as good as the sales-pitch... which, sadly, there is no indication it will be - because none of the obvious issues have been addressed.

Most of the light that is received by the retina in day to day life is highly incoherent thus it is unlikely that you can produce a destructive wavefront for it.
