Kristina Höök, IT University, Sweden
Kristina Höök is currently a professor in Human-Computer Interaction at the Department of Computer and Systems Sciences, Stockholm University/KTH. She leads a group working on affective interaction, with a particular focus on mobile applications. Kristina has also kept a part-time position at the Swedish Institute for Computer Science (SICS), where she previously was the laboratory manager of the HUMLE laboratory. Her previous work while at SICS focused on social navigation.
Gilbert Cockton, University of Sunderland, UK
Gilbert Cockton is Research Chair in HCI and Chair of Interactive Digital Media in the School of Computing and Technology at the University of Sunderland in the North-East of England. He currently directs NITRO, a £3.6M collaboration between four universities that provides access to expertise and facilities for regional digital companies. NITRO is the main university contribution to CODEWORKS, the regional centre of excellence in digital technology and media.
Gilbert has published over 100 articles, chapters and books on user interface design and specification, software architecture, development methods, contextual design, usability evaluation and accessibility. He has been active in the HCI professional and scientific communities for almost 20 years. He is currently Chair of the British HCI Group, represents the UK on IFIP TC13, and is a member of SIGCHI's Conference Management Committee. Gilbert recently stepped down as Deputy Editor of the leading HCI journal Interacting with Computers. He co-chaired CHI 2003 with Panu Korhonen of Nokia and was chair for HCI 2000. He is a Fellow of the British Computer Society and the UK's Royal Society for the encouragement of Arts, Manufactures & Commerce.
Bonnie John, Human-Computer Interaction Institute (HCII)
Carnegie Mellon University, USA
John is an Associate Professor in the Human-Computer Interaction
Institute at Carnegie Mellon University's School of Computer Science,
and Director of their Masters in HCI Program. Her research involves creating
and assessing techniques to improve the design of computer systems with
respect to their usefulness and usability. To that end, she has investigated
the effectiveness and usability of several HCI techniques (e.g., think-aloud
usability studies, Cognitive Walkthrough, GOMS) and produced new techniques
for bringing usability concerns to the design process (e.g., CPM-GOMS
and software architecture evaluation for usability).
Much of her work focuses on cognitive modeling, where she works within
a unified theory of cognition to develop models of human performance that
are applicable to the design of computer systems. These models produce
a priori, quantitative predictions of performance with less effort than
prototyping and user testing. They allow analysis at different
levels of approximation so predictions appropriate to the design situation
can be obtained with minimum effort. They are straightforward enough
for computer designers to use without extensive training in psychology,
and, because they are within a single theory of cognition, these models
are integrated enough to cover total tasks. She also works on bringing
the psychology of human-computer interaction into software engineering
techniques, specifically including usability concerns in software architecture
