Summary
This study, conducted by the AAA Foundation for Traffic Safety in partnership with the University of Utah, addresses the visual and cognitive demands placed on drivers when using in-vehicle information systems (IVIS). The research was motivated by the increasing prevalence of smartphone-integrated systems, specifically Apple CarPlay and Google Android Auto, and the need to compare their distraction potential against built-in (native) infotainment systems. The primary objective was to determine how demanding these systems are relative to one another, how demand varies across specific tasks (calling, texting, audio programming, and navigation), and how interaction modes (voice vs. touchscreen) and vehicle types influence driver workload. The methodology involved testing five model year 2017–2018 vehicles from different manufacturers, selected because their native systems supported both CarPlay and Android Auto. Sixty-four licensed drivers, aged 21 to 36 with clean driving histories, participated in the study. Testing occurred on a two-mile residential road with a 25 mph speed limit and low traffic. Participants performed four specific tasks using auditory/vocal commands and center stack displays. To quantify demand, researchers utilized objective and subjective measures, including two variants of the Detection Response Task (DRT) and the NASA Task Load Index. Drivers also completed three benchmark trials: a single-task baseline, a highly demanding cognitive task, and a highly demanding visual task, allowing for standardized comparison of workload levels. The findings indicate that both CarPlay and Android Auto generated an overall moderate level of demand, whereas built-in native systems resulted in very high levels of demand. For most tasks, the smartphone-integrated systems were less demanding than native systems. Specifically, CarPlay exhibited lower overall demand than Android Auto for sending text messages, while Android Auto was less demanding than CarPlay for programming navigation and significantly less demanding than native systems for that task. Regarding interaction modes, visual demand was lower for both CarPlay and Android Auto compared to native systems. However, optimal interaction modes differed by system: CarPlay demand was nominally lower with center stack interactions, while Android Auto demand was lower with auditory/vocal interactions. Demand levels also varied across the five vehicle models tested, with some generating high demand and others moderate demand for the integrated systems. The study concludes that compatibility with a vehicle does not guarantee safety during driving. The authors recommend that motorists restrict the use of these technologies to legitimate emergencies or urgent driver-related purposes. Furthermore, the results provide actionable data for technology companies and automakers to identify significant sources of driver demand and enhance system designs to minimize cognitive and visual distractions.
Key finding
Apple CarPlay and Google Android Auto produced overall moderate visual and cognitive demand across IVIS tasks, substantially lower than the very high demand associated with native OEM infotainment systems in the same vehicles.
