Abstract

In this paper, we describe BrainEx, a tool for similarity exploration of brain data for neuroadaptive technology. We then demonstrate how we used it to explore brain data collected in two experiments to build a foundation for neuroadaptive technology. Experiment 1 examines fNIRS data to identify periods of elevated driver workload in a simulator. Experiment 2 explores the detection of mind wandering states during a cognitive control experiment. We show that our exploratory tool can use different similarity distances for robust identification of similar patterns in the brain data during complex tasks. This builds a foundation for interactive systems that are capable of identifying cognitive states and adapting system behaviour to better support users.
