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.

  • 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.
