The trill of playing video games or watching a movie is greatly enhanced by the director’s manipulations on various speed-related effects. Speed judgment is also an extremely important factor in safe driving. As speeding causes large casualty counts in highway accidences every year, we attempt to develop an effective measure to prevent speeding incidences by altering the driver’s sense of driving speed. The idea behind this research is: Can we change a viewer’s speed judgment by altering the background pattern along the driving path? Three experiments were carried out in this research. In the first experiment, the effect of stripe pattern on a player’s speed judgment, and the degree of such effects due to different stripes was evaluated. In the second experiment, the effect of line orientations in a background pattern on a player’s judgment of speed was evaluated. In the last experiment, direction of movements was studied to see how forward movement and backward movement might affect the judgment of speed. The results show that, in a sample of six stripes, the inverse-arrow stripe results in a biased judgment towards higher speed. The orientation of a background pattern also has a significant effect on the judgment of speed. In the case of moving forwards, the greatest subjective speed is obtained when the driving movement and the stripe pattern are pointing to the opposite directions. However, when moving backwards the greatest speed occurs when the driving movement and the stripe pattern are pointing to the same direction.
