Drag those windows from your screen and into the air in front of you. Use a simple glance to switch lights, open doors or surf the web. Virtual devices, virtual objects will surround us, anywhere. Only one piece of real hardware will do it all, replace anything. From application concepts to technical design to even a fiction chapter carrying us into the future, "this book is a blueprint for an entire technology". The new edition has been greatly extended, with many new ideas and materials. From the foreword by Oliver Bimber, professor of augmented reality: "I was captivated by the last edition of 'The End of Hardware' on a round-trip flight to Los Angeles. This book is not only an in-depth introduction to the concept of head-attached displays for augmented reality (AR), but also a great source of inspiration for many professionals - at least it is for me. Being a technical guy, I particularly enjoyed reading the technical design chapter which, in this new edition of the book, has been greatly extended with many details on holography, light fields and MEMS. Despite a technological focus, the book is written in a popular-scientific style - and therefore allows easy access to the material - even for non-experts. If I were to characterize this book in a single word, that word would be 'inspiring'. I can only hope that one day, someone will pick up and realize these ideas. For although, this might not be the 'End of Hardware' - it could well be the beginning of many new and exciting interfaces to the digital world in which we all live in."
