Tico Ballagas defended his PhD in Aachen, New insight on Fitts' law.

Today I finally got around visiting Jan Borchers (media computing group at RWTH Aachen). Tico Ballagas hat as part of his PhD defence a public talk and took the chance to go there.

There where new parts in the talk on the impact of the selection space resolution on Fitts’s law that I had not seen in his work before. It is published in 2006 as a technical report (Rafael Ballagas and Jan Borchers. Selexels: a Conceptual Framework for Pointing Devices with Low Expressiveness. Technical Report AIB-2006-16, RWTH Aachen, Dec 2006) which is worthwhile to have a look at. This could be very interesting and relevant for the work Heiko Drewes does on eye-gaze interaction. Discriminating between input and output space for the index of difficulty could be helpful to understand better the impact of the errors that we see in eye gaze interaction.

One part of Tico’s research was concerned with a definition of a design space for input devices. This is partly described in a paper in IEEE Pervasive magazine, see: Ballagas, R., Borchers, J., Rohs, M., Sheridan, J.G., The Smart Phone: A Ubiquitous Input Device. IEEE Pervasive Computing 5(1). 70-77. 2006.

What an interesting blog, introduced by a thought-provoking photo. The unusual wall painting of the dwellings is also a strangely modern interpretation. Something like this hieroglyphic view of a park by Swiss painter Paul Klee, http://EN.WahooArt.com/A55A04/w.nsf/OPRA/BRUE-8LT475.
The image can be seen at wahooart.com who can supply you with a canvas print of it.
