From the reviews: "Chalmers (Univ. of Sussex, UK) has written an interesting brief work related to smart phones, sensors, and other devices that are blending into the background and becoming invisible. ... can serve as a useful guide for graduate student researchers. ... The book could be used for an introduction to sensors course, a course in pervasive computing and research techniques, or an introduction to the area for research students. Summing Up: Recommended. Upper-division undergraduates and graduate students, as well as researchers in pervasive computing sensors." (C. Tappert, Choice, Vol. 49 (6), February, 2012)
