This edited book introduces readers to the area of "Everyday Virtual and Augmented Reality". With Virtual and Augmented Reality technologies, becoming more pervasive in our homes and workplaces, new use cases and scenarios emerge together with new challenges that need to be addressed. These challenges encompass the design and implementation of appropriate VR/AR applications for ordinary environments that were not built with the explicit intention of supporting VR systems. The everyday/domestic environments present a range of issues that are usually not present in the physical locations purposed for VR and AR use in academic or professional environments, such as constrained spaces, presence of obstacles, absence of instrumentation, social and organizational restrictions etc. To address the above challenges, we collect the latest work from the Virtual Reality and Augmented Reality research community, by combining the presentation of general definitions and characterization of the field, of interaction concepts and techniques, of a variety of use cases and areas. The constellation of different environment examples (from education, sport to consumer and marketing), from across the globe and platforms, provide a comprehensive discussion on scientific and engineering methods, which enable the development of VR/AR systems in everyday context.

Now what kind of approach by the reader did THE PHILOSOPHY OF SPIRITUAL ACTIVITY count on? It had to assume a special way of reading. It expected the reader, as he read, to undergo the sort of inner experience that, in an external sense, is really just waking up out of sleep in the morning. The feeling one should have about it is such as to make one say, "My relationship to the world in passive thoughts was, on a higher level, that of a person who lies asleep. Now I am waking up." It is like knowing, at the moment of awakening, that one has been lying passively in bed, letting nature have her way with one's body. But then one begins to be inwardly active. One relates one's senses actively to what is going on in the color permeated, sounding world about one. One links one's own bodily activity to one's intentions. The reader of The Philosophy of Spiritual Activity should experience something very like this waking moment of transition from passivity to activity, though of course on a higher level. He should be able to say, "Yes, I have certainly thought thoughts before. But my thinking took the form of just letting thoughts flow and carry me along. Now, little by little, I am beginning to be inwardly active in them." - from Rudolf Steiner's AWAKENING TO COMMUNITY

Indian inhabitants laid out the basic travel routes in central Washington's Grand Coulee country probably 10,000 to 12,000 years ago. In the early 1800s, the semi-nomadic Sinkiuse and other Native Americans continued to use these routes through the spectacular coulees. Following in their footsteps came a host of white explorers and frontiersmen - at first in a trickle, then in greater numbers by mid-century. Forgotten Trails is a compilation of the most significant firsthand accounts of travel through the region. Included here are the writings of explorers, fur traders, missionaries, railroad surveyors, scientists, and artists, as well as miners, stockmen, military road builders, and packers. A chapter on traditional Plateau Indian culture, and an oral history describing 19th century Indian life in the Grand Coulee area, offer a Native American perspective.
