Improvement of speed perception in driving simulators using image deformation based on the human visual space

Driving simulators (DSs) have been widely used to develop advanced driver assistance systems to improve driving safety in vehicles. A major drawback of using DSs is the lack of speed perception while driving. Hence, improvements to speed perception have been recognized as a major priority for enhanc...
