| Summary: | Simulate is the word that have same meaning as fabricate, feign, pretend, copy, mimic, or imitate. The word “simulation” can be defined as a "technique of substituting a real environment to fake one, so that it is possible to work under laboratory conditions of control. Within experimentally controlled environment, performance measures can be defined, collected, and repeatly tested which is in a cost-effective manner (Olsen 1996). A virtual driving simulator is a device that allows user to feel a life-like experience of driving an actual vehicle within virtual reality. It is effectively used for studying the interaction of a driver and vehicle and for developing new vehicle systems, human factor study, and vehicle safety research by enabling the reproduction of the actual driving environments in a safe and tightly controlled environment (Kang et al. 2004). Mostly vehicle simulators consist of physical mockups as examples steering wheel, gearshift and pedals. These are essential in trying to simulate real conditions, then it’s become as a drawback for system becomes more expensive, more huge (non mobile), and then limited to reflect changes on the vehicle type, dimensions, or interior design (Kallmann et al. 2003).
