I’ve always been interested in virtual reality. A technological daydream that can be experienced while awake; escaping to a different place without actually traveling.
Sure, I’ve played games, even coded a few of my own. However, that’s not why I love experimenting in VR. I think it is just because I really enjoy creating.
So when I learned about A-Frame back in March 2017, at an SFHTML5 meetup, I decided I needed to get moving fast on this browser based technology which allows for VR. …
I would like to tell you about one of the things I’m the most proud of as an app developer and why I consider my app one of the most useful and successful apps out there.
The app started off as an idea to help a good friend who was hospitalized and lost the use of his voice due to a medical condition. To help him I developed an app which used computer speech synthesis to speak for him when he touched software buttons on his iPad.
At first my friends hands where so shaky and weak that he missed touching many of the buttons necessary to speak. So I made the buttons bigger and placed them in areas separated enough from each other to reduce most input errors. Also, I considered what situations he might need to speak in, different conversational settings, hospital, home, shopping and on the go. …
I wrote a previous article in which I described where to begin with VR in a browser. This took the popular A-Frame Hello World and extended it a bit, with environment and the ability to move around in that environment with the VR controllers, teleport, etc.
Pirate Translation: Treasure is hidden in this simulation, my friend.
This is really an article on how to create a compelling VR environment and experience inside a browser with A-Frame.
To be honest, I thought about having a sunken pirate ship with treasure, but that would be too many polygons and vertices.
So I opted for an office model instead, since after this article I will be writing something exploring multi-user VR access. Possibly with networked-aframe. The office would then be very useful as a meetup place.
For now let’s take a look at our working island example first. Some explanation is in order. This example takes a while to load because of all the heavy 3D graphic models and assets. In comparison, think about how long it takes a complete game to download and install the first time, and now imagine doing that for the first time while loading a web page. …
<title>Hello World A-Frame</title>
<meta name="description" content="Hello World, WebXR! in A-Frame">
<a-scene background="color: #FAFAFA">
<a-box position="-1 0.5 -3" rotation="0 45 0" color="#4CC3D9" shadow></a-box>
<a-sphere position="0 1.25 -5" radius="1.25" color="#EF2D5E" shadow></a-sphere>
<a-cylinder position="1 0.75 -3" radius="0.5" height="1.5" color="#FFC65D" shadow></a-cylinder>
<a-plane position="0 0 -4" rotation="-90 0 0" width="4" height="4" color="#7BC8A4" shadow></a-plane>
So what does A-Frame give us to begin with? The Hello World example. Well that’s cool, but I want more. Like an environment around the geometric shapes and the ability to move around in VR. …
What are you talking about? How can your code last for a thousand years?
Well let me explain, or better yet, let these videos explain . . .
“*Arctic Code Vault Contributor” if you see this message on your GitHub account overview page, then you are a contributor as well. You should be proud, because it not only acknowledges your contribution to Open Source Software, which should be enough in itself, but it says if civilization fails, you’ll be there posthumously to help in the recovery!
Now here is an even wilder thought . . . Imagine a time in the future in which AI has progressed to the point of AGI (Artificial General Intelligence), let’s assume not the Terminator kind. That AI might read millions of GitHub repositories to get examples for writing it’s own code. Assuming that AI is helping humanity, that again would be a contribution. …

Be sure to have a VR headset readily available to get the full experience while tethered to a fast internet connection.
HOW TO USE: Use your controller left thumb stick or pad to move the interface and orbs (spheres) closer to you for teleport with your right hand trigger button and the laser pointer. Then select the green play button to view the coastal video. You can also play open source music (Mozart) by toggle selecting the purple music box
Also notice the shadow of the tripod for the 360 camera on the rock in the screen shot above and the VR button in the bottom right hand corner used to enter VR with your headset. …
It has been three years now since I started coding virtual reality on the internet. As a result I’ve learned a tremendous amount!
There have been many changes in A-Frame and three.js in late 2019–2020 as a result of the move from the WebVR to the new WebXR specification; because of underlying changes to browsers, a lot of things got broke . Not to worry, I upgraded my VR samples to the new A-Frame 1.0.4 release and many of them began to work again after some cleanup. …
Video explaining how the Touch Voice app works for the speech impaired
Coming up on 10 years now, I designed and developed an app to help the speech impaired to communicate. I thought it might be interesting to review my approach to the design and where it has succeeded and also where it has fallen short.
First off, a disclaimer, I am not a medical professional nor a Speech Language Pathologist. What I am is a seasoned computer professional with decades of experience programming user interface designs and a learned development methodology. …
