Compensation for delay in the visual display of a driving simulator: effects on lane keeping
report
Interactive driving simulators with an image generating system have a delay in the feedback of the visual information, which can negatively influence the driver-vehicle system. Recently, a compensation technique for this delay has been developed for the driving simulator of the TNO Institute for Perception. In this report, an experiment is described which has been conducted to investigate the effectiveness of this technique in a representative driving task. Experienced and inexperienced subjects conducted a number of runs in the simulator, both with and without compensation. The driving task consisted of keeping the vehicle in the middle of a straight road, while external disturb-ances were imposed on the yaw angle. The effect of delay compensation was studied for several variables which are frequently used in simulator experi-ments to characterize vehicle motion and steering effort.
Results showed that the compensation has a significant effect on almost all variables. Both for experienced and for inexperienced subjects, the use of compensation caused smoother vehicle motions and a reduction in the required steering effort. The average effect size is approximately 10%. It is concluded that compensation for delay in the visual display is an effective and efficient measure to make the driving simulator resemble the real vehicle more closely.

In een experiment is nader onderzocht hoe efficient het algorithme is dat compenseert voor de beeldvertraging in de rijsimulator. De compensatie blijkt te resulteren in een simulator die beter op het echte voertuig lijkt.
