Driving safety is sensitive to conditions and diseases that affect sleep, and individuals with obstructive sleep apnea syndrome have a high risk of at-fault accidents. Most driving simulators used for research are unrealistic, stationary, prohibitively expensive, or not specifically designed to study sleep disorders. The purpose of this study was to test the feasibility of a new lowcost, portable, realistic driving simulator intended for use in sleep disorders research.

Objectives
Free, open-source software, based on Ogre3D graphics engine
Portable, inexpensive hardware
Realistic
Specifically aimed at studying daytime cognition and performance of individuals with sleep disorders
Track lane position, speed, steering wheel position, braking, acceleration, collisions, and reaction times
Configurable via XML files
