“…However, the illusion is spoiled if the cabin tilt is perceived by the driver, 6 inducing the sensation of rotational motion and resolving the ambiguity. The perception of being tilted results from integration of the neural signals from the semicircular canals, whose response is proportional to angular velocity, and from sensors coding for linear accelerations such as proprioceptors, otoliths, and somatic graviceptors.…”

Roll rate perceptual thresholds in active and passive curve driving simulation

In driving simulation, simulator tilt is used to reproduce sustained linear acceleration. In order to feel realistic, this tilt is performed at a rate below the human tilt rate detection threshold, which is usually assumed constant. However, it is known that many factors affect the threshold, such as visual information, simulator motion in additional directions, or the driver’s active effort required for controlling the vehicle. Here we investigated the effect of these factors on the roll rate detection threshold during simulated curve driving. Ten participants reported whether they detected roll motion in multiple trials during simulated curve driving, while roll rate was varied over trials. Roll rate detection thresholds were measured under four conditions. In the first three conditions, participants were moved passively through a curve with the following: (i) roll only in darkness; (ii) combined roll/sway in darkness; (iii) combined roll/sway and visual information. In the fourth (iv) condition participants actively drove through the curve. The results showed that roll rate thresholds in simulated curve driving increase, that is, sensitivity decreases, when the roll tilt is combined with sway motion. Moreover, an active control task seemed to further increase the detection threshold, that is, impair motion sensitivity, but with large individual differences. We hypothesize that this is related to the level of immersion during the task.

“…In 22 , a six-degree-of-freedom motion platform was used to study multisensory aspects of acceleration perception with vestibular heading thresholds shown to depend on ego-centric rather than allocentric movement direction. An advanced hexapod motion simulator was used for perception of deceleration in 27 , which combined equal deceleration values (-0.8 m/s 2 ) with five tilt/translation conditions, showing that a higher translation resulted in a stronger braking perception.…”

Current powertrains in vehicles offer a broad spectrum of driving modes that shape the driving experience. One crucial factor for determining the human factors aspects of this driving experience is the perception and evaluation of acceleration-a complex, multisensory process that integrates auditory, vestibular, and visual input. Two important questions that need to be answered in order to better characterize this percept include: How do individual sensory inputs influence acceleration perception? and How does acceleration perception change at different acceleration levels? To address these questions, here we used a unique setup based on a cable-robot simulator that allowed us to manipulate the different modalities at different levels of acceleration with real-world, in-car data for maximum realism. Specifically, we measured the just noticeable differences (JNDs) of acceleration perception in five different modality combinations with the same set of participants. Our results showed that auditory acceleration perception was less sensitive compared to other modality combinations. In addition, we found evidence for the validity of Weber’s law with JNDs increasing linearly with increasing acceleration level. Interestingly, the multisensory data showed little evidence for effective cue integration of auditory information in this setup. These findings lay the groundwork for a better understanding of how different modalities work together in acceleration perception.

“…Furthermore, the sub-criteria of the HTA λiϕh,k(i=1,2;k=sc,sh) could be used as evidence to explain how the level of fidelity of the simulation motion probably depends on different ratios of tilt/translation, which were mentioned in the literature. 15,31 The higher tilt ratio could lead to more negative false cues for a proprioceptive system than a higher translational ratio. Last but not least, the proprioceptive system is sensitive to HF signals, therefore the higher value of average error of the first derivative HTA, λ2ϕh, could be the reason why existing some proprioceptive false cues exist, or why some benefit cues are lost.…”

Motion cueing algorithms are used to produce a motion which feels as realistic as possible while remaining in the limited workspace of driving simulators. Several optimal motion cueing algorithms were developed to improve both the exploitation of the workspace of a driving simulator and the realistic of the simulated motion. In the dynamics model of the optimal motion cueing algorithms, several kinds of motion-sensory systems are integrated to optimize the simulated motion sensation. However, most previous works have just focused on the visual and vestibular system. The mathematical model of the proprioceptive system, that also senses the non-visual motion, has rarely been concerned. In this paper, a novel optimal motion cueing algorithm, which integrates model of the proprioceptive system, is developed to reduce the false cues from muscle spindle of head/neck system sensing lateral tilted angle. The optimal motion cueing algorithm has a significant effect on the pilot's perception when the tilted angle is rather large. An example of the simulation of a roller coaster running along a planar S-curve trajectory with only lateral acceleration is investigated with current motion cueing algorithms and optimal motion cueing algorithm. Several objective criteria were introduced to evaluate the simulated perception of all investigated motion cueing algorithms. The results demonstrate that optimal motion cueing algorithm is better than current motion cueing algorithms in most criteria and also sub-criteria.
