Andy Cockburn is a Professor of Computer Science and Software Engineering at the University of Canterbury in Christchurch, New Zealand. His research interests are in Human Computer Interaction (HCI), with a focus on improving human performance with computer systems by understanding and exploiting underlying human factors. Key problems that he has worked on include improving mechanisms for navigating within electronic documents (e.g., scrolling and zooming), navigating between electronic documents (e.g., file retrieval, window switching and web navigation), command activation (e.g., menus and hotkeys), and interfaces that facilitate transitions to expertise. He is a fan of spatially stable user interfaces and of rigorous experimental research validation. My research interests cover a range of topics within empirical Human-Computer Interaction (HCI). I am internationally recognised for conducting meticulously designed and carefully executed experiments that test next-generation computer interfaces. Our group is the only one in the Southern Hemisphere that regularly publishes full-papers in the annual ACM Conference on Human Factors in Computing Systems (ACM CHI), which largely defines the field of HCI. ACM CHI is one of the most carefully reviewed and competitive conferences in Computer Science. My primary research goal is to improve the ability of millions of computer users to carry out their everyday tasks of navigating through information. These tasks include navigating between documents (for example, on the Web) and within their documents (for example, when scrolling). Current interfaces are dramatically less efficient and effective than they might be, and my group is developing and testing new techniques that ease and speed user performance.
