Human-Computer Interaction

In Computer Science, I am interested in advanced human-computer interaction, i.e. interactions that go beyond the usual windows, keyboard and mouse interactions. The advanced interaction modalities include, for example, haptic input/output, vision-based input, virtual and augmented reality, and so on.

Eye Movements

In Psychology, I am interested in attention and eye movements with a focus on new methods for analyzing and describing eye movements. With my colleagues and students, I have developed a method for anlyzing eye movements based on recurrenct analysis. It is introduced in the paper

Anderson, N. C., Bischof, W. F., Laidlaw, K. E. W., Risko, E. F., and Kingstone, A. (2013) Recurrence quantification analysis of eye movements. Behavior Research Methods, 45(3):842-56. doi: 10.3758/s13428-012-0299-5. (available through my publications page)

A brief introduction to RQA was presented at the Workshop "Spatial and Temporal Analysis of Eye Movements" by T. Foulsham, W. F. Bischof, and A. Kingstone at ECEM 2013. The code for running RQA and Cross-RQA is available here.

We recently compared a large number of methods for comparing scanpaths, and the results of this comparison are available in Anderson, N. C., Anderson, F., Bischof, W. F., and Kingstone, A. (2014). A comparison of scanpath comparison methods, Behavior Research Methods, DOI 10.3758/s13428-014-0550-3. (available through my publications page)

Bootstrap Thresholds

In the late 80's and early 90's, David H. Foster and I were the first to apply bootstrap methods (Efron & Tibshirani, 1993) to estimating psychophysical thresholds. Our programs are still requested from time to time.
