Applied research on driver attention
We study how in-vehicle technology and vehicle automation affect driver attention. The work runs on the road, on the test track and in the simulator, and it uses the same instruments we sell.
Research areas
Cognitive workload
With David Strayer’s laboratory at the University of Utah and the AAA Foundation for Traffic Safety, Joel Cooper helped develop a rating scale for cognitive distraction and applied it to voice assistants, smartphones and in-vehicle infotainment systems. The detection response task was a primary workload measure throughout (Strayer et al., 2015; Strayer et al., 2019b).
Interface evaluation
We measure the visual, manual and cognitive demand of touchscreens, voice interfaces and portable devices with the ISO test methods, and compare the results with the acceptance criteria in the NHTSA guidelines. Studies combine occlusion, eye tracking, the DRT and video coding of driver behavior (Strayer et al., 2019a; Cooper et al., 2020).
Vehicle automation
We instrumented the vehicles and analyzed driver behavior for a hybrid naturalistic study of drivers using Level 2 automation (Cooper et al., 2023). For the Utah Department of Transportation we studied rider trust in a low-speed automated shuttle (Carriero et al., 2020).
