Abstract:
This study aimed to examine the effects of intervals between roadside columns on human speed perception. A virtual reality aided experiment was conducted, with 20 college students as participants. Each participant was asked to sit in front of a screen upon which interactive virtual space was projected. Within this space, columns emerged on the right and left of the screen at regular intervals. Participants could control the speed with which the columns moved on one side of the screen, using a mouse to move a virtual slider bar. The participants were asked to synchronize the speeds with which the controllable and uncontrollable columns moved in each experimental trial. The most important results of this study were that participants tended to increase the speed with which controllable columns moved when the intervals between them were longer relative to those between the uncontrollable columns. Results indicated that controlling the intervals between roadside columns also affected the perception of human walking and running speeds.
