Innovations in display technology, sensing systems and computational capabilities are rapidly impacting the driver-vehicle interface. New vehicle interfaces often present the driver with complex menu systems supporting a variety of visual-manual and auditory-vocal interactions. Cleary, the optimization of information can play a key role in reducing driver demand and enhancing driver focus. “Voice command” interfaces have been proposed as a means to allow drivers to engage with entertainment and connectivity systems while keeping their eyes on the road and hands on the steering wheel. Touch screens are increasing in prominence while traditional “knobs” and “buttons” are becoming less common, perhaps requiring drivers to focus additional attention to even the most basic interactions that were once just a “mindless button press”. Automation and advanced driver assistance systems are increasingly altering the basic attentional demands of vehicle control.
This talk will show how even simple changes in interface design can have an impact on attentional demand and how the intertwining of aspects of demand such as vision and cognition makes the optimization of driver attention an increasingly complex area of research. The need for new methods that consider interactions holistically and in the broader operating context (environment, automation, etc.) is highlighted as is the overall goal of more fully understanding the link between driver attention and safety as the complexity of the driver-vehicle interface continues to grow.
