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.
Snap has been making the rounds in 2025 in preparation for the launch of its consumer AR glasses in 2026. Snap introduced the Snap Spectacles 5 developer kit model in October 2024. This article discusses information I have gathered Snap Spectacles over the last year.
I just wanted to let all my readers know that the presentation I gave at AWE on June 12th, 2025, is now available on YouTube. The Video is 27 minutes long, including about 7 minutes of Q&A, and covers many of the practical and technical issues facing glasses form factor AI glasses, which include a display.
Introduction – Correcting Google AR Glasses Using Raxium MicroLEDs As I often say, few will volunteer information, but many will correct you. This is the case with my supposition about Google’s XR glasses prototype. In “Meta Hypernova and Google AR/AI…
Last week, I gave a presentation at The Vintage Computer Festival Southwest (VCF SouthWest) about the development of the TMS9918 (and related devices), which I helped define, design, simulate, and debug from September 1977 through mid-1978. In addition to the presentation, I participated in a one-hour question-and-answer session hosted by Matthew Hagarty. Matthew has developed a series of FPGA-based 9918 emulators, the latest of which is pin-compatible except for providing R, G, and B output rather than composite video.
Several technology demonstrations stood out to me at Display Week (DW) 2025. This article will cover Playnitride's Quantum Dot (QD) based full-color MicroLED, combined with Lumus's geometric (also known as reflective waveguide) technology.
As I wrote in may last article, Lumus showed me a "fantastically tiny projector" connected to their waveguide.
Meta and Google are both working on AR/AI glasses that are Monocular, Full Color, and using LCOS MicroDisplays (rather than MicroLEDs). It looks to me like Meta has chosen Lumus for its reflective waveguide while Google is using Applied Materials Diffractive Waveguide with an Avegant projector engine.
SID Display Week (DW) 2025 is coming to San Jose, CA, May 11–16. My last two articles discussed LCOS technology I saw at DW 2024 and MicroLEDs for AR at DW 2024. This article will concentrate on Micro-OLED (also known as OLEDs on Silicon), which could be used in optics-see-through (OST) Augmented Reality (AR) or Virtual Reality (VR) headsets.
