Abstract

Accidents involving using digital products in vehicles increase every year. Using digital products in vehicles can cause high visual, physical, auditory and cognitive workload. This study investigates the potential workload caused by using digital products while driving. The survey result indicates that tasks which may lead to highest average workload are searching for address in the navigation system and following the navigation. Tasks which may lead to lowest average workload are listening to the radio and voice input. According to the result, how to decrease the workload of using navigation system and how to apply the voice input into the navigation systems should be considered in the future study.
