Perceived Usability and Cognitive Demand of Secondary Tasks in Spoken Versus Visual-Manual Automotive Interaction
نویسندگان
چکیده
We present results from a study of truck drivers’ experience of using two different interfaces; spoken interaction and visualmanual interaction, to perform secondary tasks while driving. The instruments used to measure their experience are based on three popular questionnaires, measuring different aspects of usability and cognitive load: SASSI, SUS and DALI. Our results show that the speech interface is preferred both regarding usability and cognitive demand.

Speech versus visual-manual interfaces in trucks: effects on driver distraction, user acceptance, and perceived efficiency
Truck drivers often have a tight time schedule and therefore need to carry out several in-vehicle tasks while driving, such as making phone calls, writing down information and navigating to new places. Performing these tasks using a visual-manual interface can impose visual distraction which has been shown to lead to safety-critical events on the roads. Instead of using a visualmanual interface...
متن کاملMulti-modal assessment of on-road demand of voice and manual phone calling and voice navigation entry across two embedded vehicle systems
One purpose of integrating voice interfaces into embedded vehicle systems is to reduce drivers' visual and manual distractions with 'infotainment' technologies. However, there is scant research on actual benefits in production vehicles or how different interface designs affect attentional demands. Driving performance, visual engagement, and indices of workload (heart rate, skin conductance, sub...
متن کاملThe Relationship Between User Errors and Perceived Usability of a Spoken Dialogue System
An experiment (N=24) was conducted with a spoken dialogue system (a smart home system), in which the users carried out several tasks with the system and rated its usability. Users’ interactions were analyzed from the perspective of human error research done in human factors and cognitive ergonomics, distinguishing between goal-, concept-, task-, and command-level errors. This paper raises the q...
متن کاملAssessment of cognitive workload of in-vehicle systems using a visual peripheral and tactile detection task setting.
The increase of driver information and infotainment systems includes also interaction technologies like speech interaction that minimize visual-manual demand and put the focus to cognitive demand. The question is whether this could lead to distraction effects and decreased traffic safety. This study presents an evaluation method for cognitive demand based on different detection paradigms in a d...
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...
