  • Quantitative and qualitative analysis

Project Description

To test the potential of using aural flows in a context featuring higher cognitive load and distraction, a study (n=60) was conducted in a driving simulation lab. Each participant drove through three driving scenario complexities: low, moderate and high. Within each driving scenario, participants went through an alternative aural application exposure: no device, voice-controlled aural flows (ANFORADrive) or an alternative, commercially available solution (Umano). Results suggest that voice-controlled aural flows do not affect distraction, overall safety, cognitive effort, driving performance or driving behavior when compared to the no-device condition.
