VR UX by Casey Fictum aims to inform the reader on the topics of Virtual Reality User Experience, focusing on experience design, sound, storytelling, movement and user controls.
The book does not go into great depth on these topics, but rather gives a high-level overview. The book only weighing in at 100 pages, including a lot of diagrams and images.
It does provide some interesting insights regarding how to storyboard a 360° scenario, a unique problem to VR.
A lot of focus is placed on movement, be that either player or objects in the virtual world and the effect this can have on the player, i.e. VR sickness. It gives a good amount of design guidance with reasons supporting the recommendations.
There are however some inaccuracies in the book, it was published in 2016 so it is slightly out of date. In the controls input chapter where various user input options are discussed, it mentions that in VR users cannot see input devices even with the Oculus Touch controls, as they will not be projected into the virtual world. We know this is untrue as projecting the user controllers into the virtual world, as with the HTC Vive, has become common practice in VR.
This book does provide a nice overview on the topics covered, and having everything in a single place and in a very easy readable format is nice, however I do feel that most of the information contained in the book can easily be found online, and as VR is still rapidly evolving the information online will also be more up to date.
