Can search systems detect users' task difficulty?
2010
Proceeding of the 33rd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '10
Preserved Fulltext
Two behavioral signals: document dwell time and number of content pages viewed per query, were found to be able to help the system detect when users are working with difficult tasks. ...
In this paper, we report findings on how user behaviors vary in tasks with different difficulty levels as well as of different types. ...
More work is needed to explore behavioral signals for systems to learn dynamically if users are dealing with a difficult task so that they can adapt search towards the user's specific situation. ...

From these physiological signals, we can adapt a simulation in order to optimize workload in real-time, which allows the system to better fit the task to the user from moment to moment. ...
Our results show that we can use fNIRS brain sensing to detect task difficulty in real-time and construct an interface that improves user performance through dynamic difficulty adjustment. ...
Physiologically-sensed signals represent user state and can provide additional, implicit input to systems. ...
