ABSTRACT
This preliminary study, as a part of a broader study about the medical image use by experts and novices, examines the differences in image describing behavior between these two categories of users. Eye tracking technique was used to capture the image users' eye movement on the Area of Interests (AOIs). This study found that a domain expert was capable of employing nine levels of image attributes in the descriptions, while a novice was able to use only six levels. Furthermore, the expert showed stronger capability in expressing the image information needs by generating more image attributes in the descriptions than the novice, especially in terms of employing significantly more high-level (semantic levels) image attributes. We also found that the novice attended to more AOIs on every image than the expert.

Role of domain knowledge in developing user-centered medical-image indexing
An efficient and robust medical-image indexing procedure should be user-oriented. It is essential to index the images at the right level of description and ensure that the indexed levels match the user's interest level. This study examines 240 medical-...
User Eye Fatigue Detection via Eye Movement Behavior
CHI EA '15: Proceedings of the 33rd Annual ACM Conference Extended Abstracts on Human Factors in Computing SystemsIn this study we propose and evaluate a novel approach that allows detection of physical eye fatigue. The proposed approach is based on the analysis of the recorded eye movements via what is called behavioral scores. These easy-to-compute scores can be ...
