The later part of the book examines some of the applications of VR, such as scientific research, teaching, design and medicine. Grady concludes with a look at some of the drawbacks of VR, together with some speculations of where it might go in the future.
I didn't feel that this was a particularly 'gee-whiz' sort of book - it didn't generate much excitement for the topic.This may be due to the fact that Grady is a science writer, rather than a researcher in this field. Also the book is aimed at a school level readership, and did have quite a bit of the 'schoolbook' about it. But if you're interested in why VR has never quite caught on for most of us then this book has plenty of useful material.
