One method to adjust speed perception in a driving simulator is to adjust the rendered, geometric field of view (GFOV); however, little is known regarding users’ sensitivity to changing the GFOV. The current research examined 24 licensed drivers’ subjective experience with changes in GFOV during a speed matching task when examining the relationship between speed estimate and GFOV in a small-footprint driving simulator. Following the completion of the speed-matching task, participants were asked three questions regarding (1) strategy used to match speed: “What strategies did you use to complete the speed matching task?”; (2) awareness of GFOV setting: “Did you notice any changes in the simulation at any time during the experiment?”; and (3) subjective accuracy: “How accurate do you think you were in performing the task on a one to ten scale, one being ‘extremely inaccurate’ and ten being ‘extremely accurate’?” Results indicated participants were not (directly) aware of changes in the GFOV; some misattributed the change in GFOV to a change in the vehicle’s acceleration rate. Furthermore, many participants’ cited strategies that were later categorized as ‘using optic flow’ and, in general, were unsure about their accuracy in the task.
