I’ve started a blog, and one of the main series there is a very comprehensive primer on immersive design/interactive technology/technical design and implementation.
It’s the majority of a book I wrote that I feel is much easier to dissipate through a blog, and frankly much less pressure on me. It’s geared to mainly towards designers and other non-technical people, but it’s pretty thorough so will probably help round out some areas that you might be less familiar with. It’ll cover everything from hardwares, softwares, implementation considerations, design techniques, general good practices, vocabulary, and more.
Also sign up for the mailing list if you’re interested, it’s the best way to stay up to date with the series, as I probably won’t post on the forum for every single post.
