Summary
This review paper evaluates the validity of driving simulation experiments for studying driver perception, specifically addressing the controversy regarding how well simulators replicate real-world sensory inputs. The authors are motivated by the rapid expansion of simulation use in vehicle design and safety studies, which relies on the assumption that simulators provide perceptually accurate environments. However, recent psychophysical studies have highlighted significant contributions from non-visual sensory modalities, particularly vestibular cues, prompting a re-evaluation of visuo-vestibular interactions in driving contexts. The paper aims to assess whether current simulation technologies adequately capture the complex sensory integration required for accurate speed, distance, and steering perception. The authors analyze existing literature and experimental data to compare perceptual cues in real driving versus simulation. They examine visual cues such as optic flow, binocular disparity, motion parallax, and angular declination, alongside non-visual cues including vestibular and proprioceptive information. The review details the technical limitations of simulators, noting that while many provide large fields of view and optic flow, they often lack binocular cues, motion parallax due to head movement, and accurate vestibular stimulation. Specific experimental findings are cited, including studies where simulated eye-height manipulations altered perceived distance and speed, and comparative studies between full-scale simulators and real-road driving. The authors also discuss the role of extra-retinal information in disambiguating optic flow for heading control and the impact of vestibular absence on steering reaction times and lateral acceleration control. The findings indicate that driving simulators can accurately reproduce subjective speed perception when equipped with a large field of view, showing high correlation with real-world data. However, distance perception is significantly compromised in simulators lacking motion parallax and accurate vestibular cues, leading to underestimation of distances to leading vehicles. The review demonstrates that incorrect calibration of visual parameters, such as eye height, biases the perception of inter-vehicle distances and speed. Furthermore, the absence of vestibular information in simulators increases steering reaction times and reduces safety margins during curve driving, suggesting that visual cues alone are insufficient for robust heading control and speed regulation. The integration of visual and vestibular signals is shown to be crucial for disambiguating self-motion and maintaining safe driving behaviors. The significance of this work lies in its implications for the design and interpretation of driving simulation experiments. The authors conclude that while simulators are valid for certain tasks like ergonomics or alertness studies, absolute simulation fidelity is required for research into driver behavior, vehicle dynamics, and advanced driver aid systems. The paper argues that future simulators must incorporate more comprehensive sensory cues, including motion parallax and accurate vestibular rendering, to avoid biased results. This re-evaluation underscores the necessity of respecting the precise role of each perceptual cue to ensure that simulation-based conclusions are applicable to real-world driving safety and vehicle design.
