AWE 2022 (Part 7) Video – Magic Leap 2 with some Hololens 2


Part 7 of the KGOnTech and SadlyItsBradley discussion of AWE 2022 is now available on the KGOnTech YouTube Channel. Part 7 Primarily covers the Magic Leap 2. At AWE, I got to the Magic Leap 2 for their public demonstrations and a private demonstration of the selective dimming feature.

To put some issues in context for discussing the Magic Leap 2 and due to some news that came out on Hololens 2, the video starts with a short discussion of the Hololens 2 and its problems and advantages. The video skips through many of the detailed issues on the Hololens 2 and Magic Leap 2. Blog articles that cover these issues in more detail are given with links in the “Blog References” section below and the video’s description on YouTube.

At the end of my presentation, Bradley kept recording as we talked about some random AR and VR subjects. About 15 minutes of this discussion is included in the “Bonus” chapters at the end of the video.

In total, about 4 hours of video are available on YouTube (about three hours on KGOnTech and one hour on SadlyItsBradley).

Part 7 KGOnTech and SadlyItsBradley discuss various AR technologies shown at AWE in June 2022. This video is focused on Magic Leap 2. It starts with discussing Hololens 2 as a lead into the issues with Magic Leap.

First 3 Videos on SadlyItsBradley

The first three videos can be found on SadlyItsBradley YouTube site with links below:

  1. Meet the Legendary Inventor of SPRITES and AR Displays! – Mostly about me and my history in early video games to AR technology.
  2. Augmenting your World is hARd – Background on why AR is so difficult to implement. This video includes my (current list) of major 22 challenges to there ever being a successful consumer AR system.
  3. Passthrough AR vs Optical AR – The pros and cons of passthrough (camera) vs. Optical (see through optics) AR. I also discuss Lynx AR and Pancake optics.

Video or Written Blog? – Looking for Feedback

The slide presentation video format let me cover content that would have taken many blog articles and many months to write versus a couple of weeks to generate the content, record, and edit. It seems like the best way to cover so much content on so many different companies and technologies. I would appreciate your feedback on your interest in more blog articles versus videos.

I would also like to find a good format for questions and answers (perhaps a live session on YouTube). I’m thinking it would be best to have at least some of the questions in advanced so I can have pictures and diagrams ready.

Please leave your comments below or on the YouTube video.

  1. Lumus Maximus Vs Hololens 2: What eye relief is the Maximus designed for? HL2 was designed to solve a very difficult problem – allowing users to wear glasses underneath as was demanded by the enterprise market (at least 50% of workforce wear glasses, prescription inserts are not acceptable). Yes the result isn’t pretty, but that’s the fundamental reason why it is what it is. I have a suspicion if you increase the eye-relief to the same as HL2 to allow glasses underneath, the Maximus will not only lose FOV (as expected geometrically), but also banding artefacts will become apparent. Lumus would need to make a bigger waveguide, which means more pupil expansion, which means more light loss and potential for artefacts. Probably still better than HL2, but not much – waveguides are not the right approach.

    • You have a good point, and I don’t know the answer. They allow some eye relief, but I don’t know if it is enough for glasses.

      I just saw Digilen’s new Argo design at CES 2023. Interestingly, the design uses optical inserts even though the waveguide supports enough eye relief for glasses.
