Abstract

Pupil dilation is known to reflect the emotional arousal. Pleasure, effort and fear are examples of stimuli inducing the nervous system to cause dilation mydriasis. The work proposes a tool to automatically quantify the mydriasis in order to evaluate mental effort in HCI. The system uses a feature-based approach and monitors the pupil behavior during a given task. As mydriasis is entailed by various reasons, our system distinguishes the cause-effect relationships by synchronizing monitoring and test, dividing the monitoring in fixed intervals and retrieving a survey of the mydriatic events for each determined period of time. We present a case of study analyzing users resolving arithmetical tasks, viewing pictures and using a mobile application. In each scenario, tests intend to impose gradually increasing reactions to the users. The paper will present different techniques for pupil dilation measurements and related results of mental effort evaluation.
