On the feasibility of using pupil diameter to estimate cognitive load changes for in-vehicle spoken dialogues

چکیده
In a driving simulator study, we explore the feasibility of using pupil diameter to estimate how the cognitive load of the driver changes during a spoken dialogue with a remote conversant. We confirm that it is feasible to use pupil diameter to differentiate between parts of the dialogue that increase the cognitive load of the driver, and those that decrease it. Our long term goal is to build a spoken dialogue system that can adapt its behavior when the driver is under high cognitive load, whether from the driving task or the dialogue task.

Utilizing Pupil Diameter to Estimate Cognitive Load Changes During Human Dialogue: A Preliminary Study
In-vehicle spoken dialogue systems are gaining in popularity. However, it is not always clear which system behaviors might result in increased driver cognitive load, which in turn could have negative safety consequences. In this paper we explore the use of pupil diameter to help in the evaluation of the effects of different dialogue behaviors on the cognitive load of the driver.
متن کاملPupil Dilation as an Index of Learning
Physiological assessment of cognitive processes has become a topic of increased interest. The value of understanding and measuring brain function at work has the potential to improve performance. The emphasis of this paper is to discuss how pupil diameter can be applied to learning. The link between pupil diameter and task difficulty, or cognitive load, has been repeatedly demonstrated for the ...
متن کاملThe effect of cognitive load on disfluencies during in-vehicle spoken dialogue
In-vehicle spoken dialogue systems are gaining increased interest by the automotive industry. They enable the driver to perform secondary tasks (i.e. tasks not related to driving the vehicle) without having to take her eyes off the road or her hands from the steering wheel. Dialogue systems also enable the driver to speak in a natural way, without having to memorize commands or navigate through...
متن کاملUsing Task-Induced Pupil Diameter and Blink Rate to Infer Cognitive Load
Minimizing user cognitive load is suggested as an integral part of human-centered design, where a more intuitive, easy to learn and adaptive interface is desired. In this context, it is difficult to develop optimal strategies to improve the design without first knowing how user cognitive load fluctuates during interaction. In this study, we investigate how cognitive load measurement is affected...
متن کاملMeasuring Cognitive Load for Map Tasks Through Pupil Diameter
In this paper we use pupil diameter as an indicator for measuring cognitive load for six different tasks on common web maps. Two eye tracking data sets were collected for different basemaps (37 participants and 1,328 trials in total). We found significant differences in mean pupil diameter between tasks, indicating low cognitive load for free exploration, medium cognitive load for search, polyg...
