KGOnTech Video Presentations On Augmented Reality
In December and January, I was asked to present (virtually) at AR/VR MeetUps in New York and The Bay Area. Both of these presentations were recorded. Added together, it is almost 2 hours of me presenting on AR. They are nothing fancy or slick in the presentation, but simply me presenting slides on the current…
Presenting at AR/VR Creators Meetup Thursday, Jan. 14th at 2:00 PM PDT
I will be speaking (virtually) at the Bay Area AR/VR Creators meetup on January 14th (tomorrow, as I write this) at 2:00 PM Pacific Time. It is free but you must go to the Meetup link to sign up. The topic of my talk is “THE BIG ISSUES DRIVING DISPLAY AND OPTICS DECISIONS IN AR.”…
Speaking (Virtually) at New York Augmented Reality Meetup Monday, Dec 14th at 6:30 PM EST
Introduction I’m sorry it has been a while. I have been working on a bunch of different articles but had what I call “poster’s block” where I get things almost done but then have not posted them for one reason or another (perhaps a bit of ADD). Part of the problem is that they got…
Updated the Website – Apologies for the Errant Notifications
Moved Website to a New Host and Put in A New and Faster and Wider Page Layout After the last series on the Hololens 2, I was finding that the page layout “theme” was too confining and it was difficult to view the pictures. I wanted a bit wider page to make images more readable.…
Hololens 2 Display Evaluation (Part 6: Microsoft’s FUD on Photographs)
Introduction (Marketing FUD) Microsoft recently put up an FAQ page with the topic heading. Why am I unable to take an accurate photograph of my HoloLens 2 display?. The purpose of this FAQ seems to be to discourage and discredit talking picture taking of the Hololens 2 (HL2) through the optics rather than to provide useful…
Hololens Display Evaluation (Part 5: Poor Intensity Control)
Introduction – Following Up on Color Control As I noted in Hololens Display Evaluation (Part 3: Color Uniformity), one the first things when I first tried a Hololens 2 (HL2) was that colors were washed out (see below). The color was much worst than the Hololens 1. So what’s wrong with the HL2’s intensity control?…
Hololens 2 Display Evaluation (Part 4: LBS Optics)
Introduction I received an email from David Kessler, an expert in optics and who has designed several laser beam scanning displays. In that email, David wrote that my speculation Hololens 2 (HL2) might be using the pupil expansion method shown in their US10,025,093 patent (right) was incorrect. David said that the HL2 was not using a screen-like…
Hololens Display Evaluation (Part 3: Color Uniformity)
Introduction – A Single Image With Both the Left and Right Displays For today, I’m going to show a single image as seen through the left and right display in the Hololens 2 (HL2). I have verified that the pictures below match what I see with my own eyes reasonably well. The human vision is…
Hololens 2 Display Evaluation (Part 2: Comparison to Hololens 1)
Introduction – Answering a Simple Question In response to Hololens 2 Display Evaluation (Part 1: LBS Visual Sausage Being Made), someone asked, “How does the Hololens 2 (HL2) compare to the Hololens 1 (HL1) in terms of image quality.” I had read someone else comment that while he like many of the new features and…
Hololens 2 Display Evaluation (Part 1: LBS Visual Sausage Being Made)
Introduction A Hololens 2 (HL2) was purchased directly from the Microsoft store online, and I have been evaluating its display technology for a couple of weeks. Unfortunately, this further pushed out my article on MicroLEDs that I have been working. Since the HL2 uses laser beam scanning (LBS), seen by some as a competing display…
