Progress in (self)motion research
report
In 2002 my colleague and friend Alex Wertheim went into early retirement. He continued his professorship at the University of Utrecht, but left TNO Human Factors in December. At his sooner than expected farewell party I expressed my desire to offer him one more get-together, but now with insiders in the area of his main scientific interest: the field of motion perception.
For this Alex selected an intimate group of kindred spirits. Interestingly enough it turned out to be an exclusively European party. In a workshop on November 7th, 2003 at TNO Human Factors, these researchers presented their current findings and discussed the progress in the work of the other participants. Although by intention the topics under discussion were specifically related to Alex's work and interest, together they comprised a broad spectrum in the motion perception domain. Tom Freeman and Jan Souman dealt with several aspects of motion perception during eye movements, Tom from a top down and Jan from a bottom up perspective. Stefan Mateeff re-introduced the concept of stimulus "strength", which is somewhat neglected nowadays, and presented a paradigm to bring this into measure. Thomas Mergner and Isabelle Israel, specialists in the area of self-motion, contributed by means of crossover. Thomas via his background in (vestibular) modelling made clear that object motion perception is shaped by the motor control mechanisms of ocular pursuit, and Isabelle elegantly stressed the missing link in our knowledge about the influence of cognition in the (active) control of motion during transportation. At the end of this fine day, Alex of course got plenty of time to appreciate the presentations in the light of his thoughts. People who happen to know him, know that he likes to have the last word. The presentations given during the workshop are gathered in this report. Together they form a vivid example of the progress which is continuously made in (self)motion research, but give also the unavoidable impression that there is much more to learn.
