In Part 1 of this multi-part series on the Meta Ray Ban Display Glasses, I will focus on the display and optical path.

It seems like all of a sudden, several companies including Meta are talking about the issue of disparity. Of particular issue with Meta, Magic Leap, and Avegant is the issue of visual distortion due to the frame twist of AR glasses frames.

Introduction: Challenge from Bosworth Accepted Several people pointed me to an interesting Instagram video AMA (ask me anything) by Meta CTO Andrew Bosworth on October 21, 2024, that appeared to challenge my October 6th article, Meta Orion AR Glasses (Pt.…

Update: A second reader with expertise in Waveguide believes (but, like my other reader, does not have direct knowledge) that the Snap Spectacles 5 is still using a waveguide with gratings on only one side. This second reader cites the…

Update (Oct. 19th, 2024) While the general premise of this article is that Meta Orion is using similar waveguide technology to Snap (Wave Optics) and that Magic Leap 2 is correct, it turns out that a number of assumptions about…

Introduction While Meta’s announced Orion prototype AR Glasses at Meta Connect made big news, there were few technical details beyond it having a 70-degree field of view (FOV) and using Silicon Carbide waveguides. While they demoed to the more general…

I saw the Cogni Trax hard edge occlusion demo last week at SID Display Week 2024, and it epitomized the concept of being a "magic show." In this article I explain the concept behind Cogni Trax hard edge occlusion and why I don't think it will ever be practical.

Humane AI (Humane, hereafter) combines the mid-2010s failed concept of using a laser projector to project on the body with the early 2000s failed projector phone (something I wrote about in 2013), only they left out the phone's flat panel display and have more feeble processing than a good smartphone. Rational people wonder what this does that a good smartphone can't do much better, and you can count me as one of these people.

At AWE 2023, I gave a 25 minute presentation on the topic of Optical Mixed Reality (MR) versus Passthrough MR. I received many requests for a copy of the presentation. I had enough information on the 38 slides for a 2 hour presentation on the topic so I had to go through them rather quickly and pick and chose what was discussed so I decided to publish the slides.

Introduction – Contrast in Approaches and Technologies This article will compare and contrast the Vuzix Ultralight, Lumus Z-lens, and DigiLens Argo waveguide-based AR prototypes I saw at CES 2023. I discussed these three prototypes with SadlyItsBradly in our CES 2023…
