Last month at MicroLED and ARVR Connect, I gave a "Master Class" on the conference's first day. I tried to cram about 2 hours of content into a 1-hour presentation. I presented on the trends I saw in optical see-through (OST) AR in 2026. With the conference's permission to use the video, I decided to turn my presentation into a series of articles.

Last month I attended and participated in MicroLED and AR/VR Connect in Eindhoven. This conference reminds me of the early days of SPIE's AR/VR/MR conference in that it is drawing some excellent speakers and companies while still offering some excellent opportunities to meet and network with people.
As a sign of the times, it seems many MicroLED companies are now putting an emphasis on optical interconnects and Co-Packaged Optics (CPO) for use in AI data centers.
The one very bright spot is that there seems to be a very big market for audio to visual translation being reported.

Introduction At Meta Connect in September 2024, Meta demonstrated its Orion prototype, which uses Silicon Carbide (SiC) diffractive waveguides to support a 70-degree FOV (see my several articles and videos on Orion). On several occasions, Meta has stated that it…

Ron Mertens of OLED-Info, MicroLED-Info, the MicroLED Association, and one of the organizers of MicroLED & AR/VR Connect asked for my input on “Why is there no 'simple' solution, where we place a transparent display in front of the user [for AR]?” Or more simply, why aren’t ‘transparent’ OLEDs/MicroLEDs being used in optical-see-through (OST) AR headsets?
I ended up writing a rather long response to Ron, and he wanted to publish it on his OLED-Info Pro (paid subscription (link: https://www.oled-info.com/karl-guttag-transparent-ar-displays-article). I agreed on the condition that I put a summary on this blog.

In this short article, I will provide links to some videos I made at AWE 2026 and invite you to join me for my presentation and a panel at MicroLED and AR/VR Connect in Eindhoven in September.

With CES and SPIE's AR/VR/MR conferences, January is always a very busy month for me. This year, I either met with or saw presentations from over 60 companies. For this first article about CES and AR/VR/MR, I discuss Google (Android XR) and Meta.

Introduction – Display Skeptics Videos It can take me weeks to prepare an in-depth study of a particular AR product, and I have been looking for an outlet to provide more information more quickly. Former Apple engineer Radu Reit and…

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

Introduction Just a short note today. I’m in the middle of my trip, which will end in Eindhoven next week (see notice at the end of this article), when I heard that Meta had leaked a video on YouTube of…

I'm to be very busy in September, including traveling to and speaking at the MicroLED and AR/VR Connect conference in Eindhoven, Netherlands, from September 23rd to 25th. If you would like to meet with me in Eindhoven, please send a meeting request to meet@kgontech.com.
I also want to let you know about an interview I did with The Voices of VR Podcast at AWE 2023, which was released on August 2, 2025.
