The concept of 'ubiquitous computing', or the integration of computing devices into everyday objects of daily human life, was first described by Mark Weiser. In his words, "The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it." The reality of this notion can be seen in cell phones, iPods, GPS devices, Google glasses etc today.
