Driver activity recognition in virtual reality driving simulation

In this research, we present the design of a driving seat with driver activities recognition based on a passive method for measuring body-postures by using two force sensor arrays to inspect the pressure patterns exhibited in driver's seat and backrest. The seat is designed by testing the sensors distribution to find the most suitable distribution to make the recognition more accurate. A Virtual Reality (VR) driving simulation is developed to test the accuracy of recognition in immersive environment. Experiments carried out to test the posture recognition accuracy in both realistic setting and VR setting. The result showed that the system was able to recognize ten different postures with various accuracy ratio. The VR immersive driving environment enhanced the accuracy recognition in some postures.
