Virtual Reality is a subdivision of computer graphics and the latter is intensely mathematical. But this book eshews a mathematical bent. Instead it offers a sweeping survey of recent [2008-9] applications of VR. You can easily read this and get a good understanding of where VR is being used. The survey spans both academic and industrial/commercial efforts.



The book is also aided by a heavy use of illustrations, many in colour. Quite appropriate given that we are talking about graphics. The figures greatly help the understanding of the text.



One interesting subtopic is augmented reality. Where typically a user wears a special pair of glasses and walks around the real world. Depending on her location and perhaps orientation, the glasses communicate wirelessly with a GIS-aware database that downloads information to be displayed in an overlay fashion on her vision.
