Understanding Driver Distraction and Cognitive Load

The video discusses the dangers of driving distractions and the concept of cognitive load. It explores how scientists use AI to measure workload through physical signs like heart rate and skin conductance. Studies using driving simulators and real highways help develop algorithms to assess workload. Alternative methods like fNIRS are also explored. The video highlights the risks of both high and low cognitive load, suggesting ways to maintain driver engagement. It concludes with a sponsor message from Brilliant, an online learning platform.
