AWE 2022 Review/Discussion Video Part 5

LCOS, DLP, LBS, and Waveguide Vision Correction plus Meta’s Name Change


Part 5 of the KGOnTech and SadlyItsBradley discussion of the various companies I met with at AWE 2022 is now available on the KGOnTech YouTube Channel.

As I wrote last time, Bradley of SadlyItsBradly and I recorded almost 7 hours of video about AWE 2022. To make it more manageable, the recordings have been broken down into 7 parts. The first three parts were release on SadlyItsBradley and KGOnTech is releasing parts 4 through 7. I expect to have the remaining two parts on MicroLEDs and Magic Leap 2 up in the next few days.

The editing is still a bit rough with jump cuts, but I wanted to get as much content as I could up quickly.

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.

Parts 6 through 7 on AWE 2022 to be released soon

I have the rough cuts completed on 3 more videos which will each be about 1 hour covering the following subjects. I expect these to be release over the next week.

  • Part 6 – MicroLEDs for Augmented Reality
  • Part 7 – Magic Leap 2 (and Hololens 2)

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. Hello Karl,

    While I do appreciate your videos, generally I prefer the written articles focused on a particular topic.

    Just my two cents.

    Thank you for your work, it’s great.

    • Thanks for the feedback. I’m curious about what “today’s audience” likes best. I also appreciate that the written format is better for many subjects.

  2. I personally prefer the video content. Was able to watch all 7 hours continuously, and it’s great hearing you ramble off about things you know a lot about (although Bradley would cut you off sometimes to shorten the video). Would like to see more of it

    • Thanks,

      I’m hoping to do more videos in the future. I did several other videos in the last two years (see list below) and I will likely be on the AR Show Podcast again in the 1st quarter of next year.

      April 11th 2022 New York Augmented Reality, The Great Display Debate with Jeri Ellsworth and Karl Guttag

      A two-hour YouTube video from the December 2021 meeting includes presentations by Jeri Ellsworth of Tilt Five, Magnus Runesson of Resolution Games, Jay Wright of Campfire, and myself (link directly to my presentation:

      The New York Augmented Reality Meetup on December 14th, 2020 video is on Google Drive (–OBKZGnlPa1Uki7out4VFS — double click to have it play), and my presentation starts at 34:30 and runs about 30 minutes plus some Q&A. This presentation is more of an overview of AR. If you can take 2 hours of watching me present, then watch this one first, followed by the Bay Area presentation.

      The Bay Area VR-AR-XR Creators Meetup on January 14th, 2021 is available on YouTube . My presentation runs about 1 hour plus Q&A (the link is queued to the start of my presentation). This presentation digs deeper into the major optical designs used in AR and the various Display Technologies. A key point I make is that not all optical designs work with all display technologies.
