This paper offers a low-cost solution that enables synchronizing three types of devices often used in driving-distraction research: driving simulator, eye tracker, and physiological monitor.


Analyzing the effects of driver distraction and inattention on cognitive load has become a very important issue given the substantial increase in the number of electronic devices which are finding their way into vehicles. Typically, separate equipment is used for collecting different variables sensitive to cognitive load changes. To be able to draw reliable conclusions it is important to possess dependable ways of synchronizing data collections between different equipment. This paper offers one low-cost solution which enables synchronizing three types of devices often used in driving research: driving simulator, eye tracker. and physiological monitor.
