Abstract

Recent research has pointed towards further understanding the cognitive processes involved in interactive information retrieval, with most papers using secondary measures of cognition to do so. Our own research is focused on using direct measures of cognitive workload, using brain sensing techniques with fNIRS. Amongst various brain sensing technologies, fNIRS is most conducive to ecologically valid user studies, as it is less affected by body movement and can be worn while using a computer at a desk. This paper describes our two pronged approach focusing on a) moving fNIRS research beyond simple psychological tests towards actual interactive IR tasks and b) evaluating real search user interfaces.
