Continual technological evolution has led to an explosion of new techniques in Human-Computer Interaction (HCI) research. Research Methods in Human-Computer Interaction is a thoroughly comprehensive guide to performing research and is essential reading for both quantitative and qualitative methods. Chapters cover a broad range of topics relevant to the collection and analysis of HCI data, going beyond experimental design and surveys, to cover ethnography, time diaries, physiological measurements, case studies, and other essential elements in the well-informed HCI researcher's toolkit. “This book is a must read for anyone in the field of Human-Computer Interaction. The multi-disciplinarian approach, housed in the reality of the technological world today, makes for a practical and informative guide for user interface designers, software and hardware engineers and anyone doing user research.” Dr. Mary Czerwinski, Research Area Manager, Microsoft Research, USA “Research Methods in HCI is an excellent read for practitioners and students alike. It discusses all the must-know theory, provides detailed instructions on how to carry out the research, and offers great examples. I loved it!” Professor Vanessa Evers, Professor, Human Computer Studies Lab, University of Amsterdam, the Netherlands "The book is superb: comprehensive, clear, and engaging! This is a one-stop HCI methods reference library. If you can only buy one HCI methods book, this is the one!" Dr. Clare-Marie Karat, IBM TJ Watson Research, USA, and recipient of the 2009 ACM SIGCHI Lifetime Service Award “A much needed and very useful book, covering important HCI research methods overlooked in standard research methods texts.” Professor Gilbert Cockton, School of Design, Northumbria University, United Kingdom
