This sounds great.<p>In a past role, my job was to develop an immersive, online learning platform. We used Oculus Quest 2s to do foreign language training for DoD personnel. WebXR, Three.js, etc, because I had had enough Unity3D for one lifetime and we didn't want to submit to app store reviews. We had a fleet of our own devices, so it was fine.<p>One of the biggest challenges with the project was creating a workflow for didactic content. By myself. I had an employee who I supervised working for me, but most of the work was of such high technical level that it was way over their head and we couldn't afford to hire anyone else. I eventually landed on having our actual language instructors use PowerPoint to create PDFs, use a bespoke editor I created to upload the PDF into a content database and position them in the training environments, and then used PDFJS to render them to canvas elements to then texture on a 3D quad.<p>Something like this would have made it possible for me to avoid having people go out of band into PowerPoint to make those materials. The PowerPoint route did dramatically improve our workflow speed over a previous attempt to get people to author images in Photoshop. But if I could have built the "sign" editor into the app, it would have improved it even more by eliminating the "guess what will look good in the environment, export to PDF, upload to the database (oh, BTW, not a lot of people know how to keep files well organized), then find out how it really looks" cycle.<p>Oh well. We didn't have a business development team or market department that knew anything about selling products instead of services, so I guess the point is moot anyway.
