ABSTRACT
We report findings on how the user's perception of task difficulty changes before and after searching for information to solve tasks. We found that while in one type of task, the dependent task, this did not change, in another, the parallel task, it did. The findings have implications on designing systems that can provide assistance to users with their search and task solving strategies.

Can search systems detect users' task difficulty?: some behavioral signals
SIGIR '10: Proceedings of the 33rd international ACM SIGIR conference on Research and development in information retrievalIn this paper, we report findings on how user behaviors vary in tasks with different difficulty levels as well as of different types. Two behavioral signals: document dwell time and number of content pages viewed per query, were found to be able to help ...
Task difficulty as a predictor and indicator of web searching interaction
CHI EA '06: CHI '06 Extended Abstracts on Human Factors in Computing SystemsThis study explored how the perception of task difficulty affects information searching interaction. We analyzed how the relationship between perceived task difficulty and information searching interaction varies by different types of tasks. These types ...
Task difficulty in information searching behavior: expected difficulty and experienced difficulty
JCDL '05: Proceedings of the 5th ACM/IEEE-CS joint conference on Digital librariesThe purpose of the work is to better understand the issue of task difficulty from the perspective of the user. To investigate the relationship between task difficulty and information searching behavior, two types of task difficulty are considered: ...
