Helands (mechanical and aerospace engineering, Nanyang Technological U., Singapore) presents a basic textbook for a first course in human factors/ergonomics at the undergraduate or graduate level. Characterizing human factors/ergonomics as a systems science, he argues that designing an artifact or interface requires considering the interactions between the operator/user, the environment, and the machine/computer. Solutions and discussions for the examples and exercises are available on the web. No date is noted for the first edition. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)
