Lovely idea and format. I would imagine that this book is an valuable supplemental reading/reference for students as well as professional product/graphic designers. The references to seminal works that defined each principle were an excellent addition to the book.
The description indicated that this was a cross-disciplinary text so I was somewhat disappointed that I found that few principles that applied specifically to the environmental design disciplines and even fewer examples that clarified how universal principles might be used in environmental design -- for example modularity was defined solely in terms of modular electronics when it is widely used in furnishings, interiors and buildings. However, one could quibble about the inclusion/exclusion of each principle and example and perhaps the range of scale is too great to include environments in a robust way.
The title is a bit confusing "universal design" is a term that is used by environmental designers to indicate an approach towards inclusion of the widest segment of the population in design solutions (including disabled people, etc). Interdisciplinary design principles may have been a more clear description of the authors intent.
Overall a valuable book -- I would certainly recommend to industrial/product design students and other related disciplines
