Hi - I'm Simon, and I've been leading the development on the low-level runtime bits for Zapbox. We synthesise the views for the left and right eyes by projecting the camera image onto some assumed world geometry. Our 6-DoF experie

OP here - I'm hoping by posting a forum thread explicitly stating their current behaviour is broken and providing a link to the spec that they are violating will allow Amazon to accept they have an issue and hopefully fix it. There are

No worries, I imagine many teams have been through the same process over the past couple of weeks! We've definitely had the same experience of Safari introducing way more issues with new releases than Chrome, and the fact it's par

Chrome 91 on Android also managed to break WebAssembly memory growth which affects our sites too, so it's been a rough couple of weeks working around browser bugs for us. https://bugs.chromium.org/p/v8/issues&

I wrote up the bug report for this a couple of weeks ago when iOS 14.6 first rolled out. iOS 14.6 at least did finally fix using HLS streams in gl.texUpload2D() on iPhone 12 series (which was broken since launch) but this new bug did mean o

Hi all, I'm the guy in the walkthrough video. ZapBox started as a Google Cardboard-inspired approach for video see-through MR, but we've now completely redesigned the physical product for the ZapBox use case. The linked video show

Thanks for the note, I'll add some more caveats to that section; I don't really know anything about the human vision system. Do you know of any better mathematical models of human perception that I could use to produce more accura

The video makes no claims of how small the tech is, but I agree it's unlikely to be in a consumer package at this stage. The display itself is mainly passive optical components. The input light can come from a single optical fibre from

And from the video linked in the Gizmodo article, Graeme Devine claims they don't call it AR because "that is just a 2D HUD", and that's why they insist on the weird marketing phrase "Cinematic Reality". To me

In the land of "not really good enough". Additively mixed at a single focus depth plane, not dissimilar to the hacks people have been using in research for AR for a long time. It does however really annoy me the amount of press Ma

My main point is that making the ideal AR display is hard. To get anywhere close needs controllable opacity and virtual focus planes. From the patents that's definitely the direction Magic Leap are heading in. If such a device exists a

It's more about capturing the spectrum from AR to VR in a single device. With controllable opacity (which I argue is required for a truly useful AR display) you also have the option to deliver purely VR experiences by blocking out the

To expand upon what the problem is: imagine rays of light reflecting from a point going in all directions (essentially a sphere). A cone of those rays make it into your eye through the pupil. Putting a 2D layer just near to the eye means li

A big unanswered question I have is what the level of transparency is going to be when the display is inactive. For me it needs to be basically 100% to enable an "always worn" piece of hardware. The patents around the lightfield w

by tb100 12y ago
Yeh, the controllable opacity is really important to the utility of the device IMHO. I've yet to study the linked patent so can't say if that solves it but it's not as simple as just a layer of LCD pixels, as they would not b

In general you just to provide the depth map too. You're still only rendering for one viewpoint (well OK, one for each eye) so the display just needs to simulate the depth and colour of the point nearest to you along any ray.

I'm co-founder and research director of a mobile AR software company, Zappar. I blogged on Magic Leap a few weeks ago, and came to some of the same conclusions as the author of the gizmodo piece - namely that a device that can be like
