Virtual Reality

VR (virtual reality) is a way for humans to visualize, manipulate and interact with computers. The emphasis of this book is on a "learning by doing" practical approach, by supporting practical activity. It shows how to construct a data glove, (a hand input device for a computer), and a tracker, (a device for monitoring motion of hands and heads in 3D space), using basic electronic hardware and computer software. Information on how to build virtual worlds, (graphical computer environments), is also be given.
