Other Work

This page lists work that is not strictly text entry.

Eye Tracking

In spring 2000 I implemented the Minimal Device Independent Text Input method on eye trackers. I wrote a paper on the project including discussion on other text input systems known to me at that time that could be implemented in similar manner. The paper titled Text Input Methods for Eye Trackers Using Off-Screen targets was presented at ETRA2000. This led me to cooperation with the Gaze-Based Interaction Group (GBIG). Since the year 2000 we have had many interesting discussions, but I have not been involved in any further publishable pure Eye tracking work. Lately I have been hanging around (and sometimes contributing to) some COGAIN work packages.

Electromyography + Eye Tracking

The people in the Research Group for Emotions, Sociality and Computing (ESC) are doing interesting experiments involving EMG measurements on facial muscles. I participated in work that combined eye tracker for pointing and a facial muscle for clicking. A poster regarding the results was presented at ECEM11. Later, a paper with more details was published in the ACM Transactions on Applied Perception.

Fitts' Law

Scott MacKenzie's work on Fitts' law as a tool in modeling user performance with certain text input methods led me to take another look at the huge body of work that is available on Fitts' law in HCI. In an attempt to understand the issue I have written a paper (in Finnish) on Fitts' law and some of the HCI modeling tools based on it. To get a more practical grip on Fitts' law work I have run tests on pointing devices along the guidelines given in ISO-9241-9 Appendix B. A Part of this work was published in APCHI2002 in the form of a paper concerned with the speed and accuracy of six mice. After that I have been involved in some other pointing device work including the TrackMouse work by Martin and Raisamo. The results so far have been meager.
