John Paulin HansenJohn Paulin Hansen

Doctor in Psychology

Interested in gaze interaction, usability, gaze-typing

Head of the research group for Innovative Communication, is an Associate Professor at the IT University of Copenhagen. He received a MSc in 1984 and a PhD in 1992 both in Psychology from Institute of Psychology, University of Aarhus. His research areas are human factors, cognitive modeling and gaze-based interaction.

John has published more than 20 research papers within this area. John Paulin Hansen has used eye tracking technology for usability studies for more than 15 years and is currently project leader of the Eye Gaze Research Team at the IT University of Copenhagen, designing and managing the development of gaze-based communication systems for disabled people.

He initiated and is co-organizing the IST EU Sixth framework programme “Communication by Gaze Interaction” (COGAIN), 2004 - 2009, with more than 100 researchers from all over the world. He is vcice-president of the COGAIN association and COGAIN liaison for the ACM ETRA conference.

 

Dan Witzner Hansen

Dan Witzner Hansen

Doctor in Computer Science

Interested in eye tracking, gaze estimation, image analysis

Associate professor at the IT University of Copenhagen within the Innovative Communications Group (since 2008). His research interests are within image analysis and machine learning with a particular emphasis on robust and low-cost eye tracking and their applications. Within eye tracking, his interests spans gaze estimaton (fully, partially and uncalibrated setups), robust methods for image processing and noise tolerant gaze interaction. Within eye tracking research he is aiming towards "Mobile eye tracking in the wild". A review paper on this topic is available in his publications. Generally he is interested in computer vision and machine learning for computer interaction research and applications.

Dan Witzner Hansen holds as Ms.C in Computer science and mathematics from University of Århus and a PhD from IT University, Copenhagen. He has been a visiting scolar at Cambridge University and post doc. at the Technical University of Denmark. He has been reviewer for several journals (e.g.International Journal of Computer Vision, IEEE Transactions on Pattern Analysis and Machine Intelligence, IEEE Transaction on Biomedical engineering), program committees for international conferences and has been involved in initializing and co-organizing international research networks ( the IST EU Sixth framework programme “Communication by Gaze Interaction” (COGAIN)) and national research projects (Danvifo.dk)

 

Javier San AgustinJavier San Agustin

MSc in Telecommunication Engineering

Interested in gaze estimation, eye tracking and multimodal interaction

PhD student within the Innovative Communication group at the IT University of Copenhagen. His research is on low-cost gaze interaction, with a special emphasis on the development and performance evaluation of gaze trackers built from off-the-shelf components.

He is interested in gaze estimation techniques in uncalibrated scenarios (i.e. setups where the location of hardware components is unknown), in mobile gaze interaction on head-mounted displays, and in multimodal input by combining gaze pointing and EMG clicking. Javier's research includes development of algorithms for eye tracking and gaze estimation using low-cost hardware components such as webcams and videocameras, and the evaluation of gaze-based interaction in tasks such as eye-typing and target-selection.

Javier holds a Telecommunication Engineering degree from the Public University of Navarra. After completing his MSc, he joined the Gaze Interaction Group at the same institution, where he contributed to the development of a new gaze tracking system for the Spanish company Iriscom. His work included the development of algorithms for fixation detection and gaze estimation.

 

Sune Alstrup Johansen

Sune Alstrup Johansen

MSc in Information Technology

Interested in usability, eye movement analysis and human-computer interaction

PhD Fellow at the IT University of Copenhagen. Sune Alstrup is doing research about eye tracking as a method for analyzing Human-Computer Interaction and communication. Analysis of eye movements can help designers improve usability and performance of user interfaces, and within the marketing domain eye tracking analysis can help optimize marketing communications.

Sune Alstrup Johansen has 8 years of experience as a usability specialist working for Grey Global Group in the Communications industry, and BEC in the financial industry. During his time as a usability specialist he has done usability testing for large international clients like Nokia, and has spent 5 years applying and validating eye tracking methodology as a usability practitioner.

Recently Sune received a grant from the world’s largest entrepreneurship foundation, Kauffman Foundation, which includes half a year abroad with visits to some of the most interesting US universities, such as Stanford and Harvard.

Sune is a board member at the local Danish SIGCHI chapter, Special Interest Group on Computer-Human Interaction, and he has been one of the organizers of Interaction Design Day and World Usability Day in Demark.

 

Henrik Hegner Tomra Skovsgaard

Henrik Hegner Tomra Skovsgaard

MSc in Software Development

Interested in multimodal interaction, gaze-typing and language modelling

PhD student at Innovative Communication group at IT University of Copenhagen. His research is within noisy gaze and multimodal interaction. Henrik is developing methods for optimizing interfaces partly by spatially changes, partly by property changes of the visual interaction objects and in part by predictive modeling by examining the noise-imposed inputs from devices. Furthermore, he has a strong focus on usability and productivity and what communication needs cognitive handicapped and physically disabled people have that can take the above improvements into account.

Henrik holds a B.Sc in Information and Communication Technologies at Copenhagen University College of Engineering and a M.Sc Software Development at the IT University of Copenhagen. After his B.Sc he started working at RISØ, Metal Structures in 4 Dimensions in the department of Material Research, developing software for a synchrotron in Grenoble, France. During his M.Sc he was employed at IBM, Global Solutions and after his M.Sc he worked as a scientific assistant in Innovative Communication group continuing his work on his thesis and other projects.

Henrik is a member of the PhD study board and he is involved in teaching in the Multimedia Technology course at ITU.

 

Martin TallMartin Tall

MSc in Cognitive Science

Interested in interaction techniques, gaze interaction and interface design

Martin is currently on a leave to Stanford University, USA. 

Ph.D student at the IT University of Copenhagen within the Innovative Communications Group since August 2008. His primary research interest are state-of-the-art gaze interaction interfaces. Martins ambition is to seek new interaction methods, either unimodal relying on a single source of input, such as an eye tracker, or in combination with other modalities. Martin has an interest in Cognitive Science and sees great potential in interactive eye tracking applications due to the close mapping between our gaze position and attention. Furthermore, he is interested in usability and interface design and seeks to develop interfaces that are easy to learn and use for a wider range of users, some of which cannot operate traditional modalities (such as the keyboard or mouse). Martin also keeps track of what is going on in the domain of eye tracking/gaze interaction, both academic and in the commercial sector through his blog on gaze interaction.

Martin holds a M.Sc in Cognitive Science from Lund University in Sweden which resulted in the NeoVisus prototype interface for gaze interaction. Before that he went to spend a year at the University of California at San Diego, where he specialized in Cognitive Science with aspects of Neuroscience, Physiology and Computer Science. His B.Sc in Informatics is oriented around software design, development and distributed systems. In addition to academic studies Martin has a background as a software developer working with Internet-related technologies, networks and databases.
