Experimental Research Methods for Human-Computer Interaction

Knowing how to design and conduct experiments (“user studies”) is a skill required of all researchers in human-computer interaction. This course will examine the scientific foundations of experimental research, the rudiments of designing and conducting an experiment, and the tools and procedures for hypothesis testing.

Time and location

Monday 3rd and Tuesday 4th of December 2012
University of Tampere (Kanslerinrinne 1). In building Pinni B, hall B3111.

Abstract

One feature of this course is participation in an experiment (lasting about 30 minutes).  Working in pairs and using a hand-out prepared by the presenter, attendees take turns acting both as participant (performing tasks while data are collected) and investigator (instructing the participant, administering the tasks, collecting and recording data).  Although only using a paper mockup, the experiment will have all the components of a real experiment.  There will be independent variables, dependent variables, counterbalancing, and so on.  Testing the research questions through an analysis of variance (ANOVA) is presented and explained.  Note that prior knowledge of statistical tests is not required.

Publication is the final step in research.  And so, this course also includes some pointers and tips on writing-up a research project – including the methodology and results of the experiment – in a paper that is formatted and ready for submission to an HCI conference.

About the Presenter

Professor Scott MacKenzie's research is in human-computer interaction with an emphasis on human performance measurement and modeling, experimental methods and evaluation, interaction devices and techniques, text entry, language modeling, gaming, eye tracking, touch input, and mobile computing. He has more than 130 publications in the field of Human-Computer Interaction (including more than 30 from the ACM's annual SIGCHI conference) and has given numerous invited talks over the past 20 years. Since 1999, he has been Associate Professor of Computer Science and Engineering at York University, Canada.  Home page: http://www.yorku.ca/mack/
