Virtual Reality (VR) and Augmented Reality (AR) are two expressions that have recently appeared in the media but which remain largely unknown to the general public and professional world. This book aims to improve our understanding of these technologies by exploring the way in which they function and the applications we can expect for future users.

VR and AR have existed for a long time but have primarily been limited, until now, to the research domain and a few large companies. The emergence of new low-cost devices (HMDs, sensors, etc.) has led to the rise of new applications for the wider public.

In order to appreciate the advantages these new technologies bring, as well as the flaws which remain to be rectified, this book defines fundamental concepts and describes practical usage examples. These recent technological developments are then placed within a temporal dynamic by recalling the major evolutions of the past ten years and by providing some prospective avenues for the future.
