As computers proliferate and as the field of computer graphics
matures, it has become increasingly important for computer
scientists to understand how users perceive and interpret computer
graphics. Experimental Design: From User Studies to Psychophysics
is an accessible introduction to psychological experiments and
experimental design, covering the major components in the design,
execution, and analysis of perceptual studies. The book begins with
an introduction to the concepts central to designing and
understanding experiments, including developing a research
question, setting conditions and controls, and balancing
specificity with generality. The book then explores in detail a
number of types of experimental tasks: free description, rating
scales, forced-choice, specialized multiple choice, and real-world
tasks as well as physiological studies. It discusses the advantages
and disadvantages of each type and provides examples of that type
of experiment from the authors' own work. The book also covers
stimulus-related issues, including popular stimulus resources. It
concludes with a thorough examination of statistical techniques for
analyzing results, including methods specific to individual tasks.
