“…Vibration presents a health risk to the psychomotor, physiological, and psychological systems of the body when exposed to these occupational environments. The most known disorder is “motion sickness,” which affects travelers and drivers during flying and driving, as well as when inside a public road transportation [ 70 , 71 ]. Short-term exposure to vibration within the range of 2–20 Hz at 1 m/s 2 may induce abdomen pain, headache, chest pain, nausea, loss of equilibrium, muscle contraction with decreased performance in precise manipulation tasks, shortness of breath, and influence on speech [ 72 , 73 ].…”

The effect of horizontal acceleration on human visual acuity and stereopsis is demonstrated in this study. Twenty participants (mean age 22.6 years) were enrolled in the experiment. Acceleration from two different directions was performed at the Taiwan High-Speed Rail Laboratory. Gx and Gy (< and >0.1 g) were produced on an accelerating platform where the subjects stood. The visual acuity and stereopsis of the right eye were measured before and during the acceleration. Acceleration <0.1 g in the X- or Y-axis did not affect dynamic vision and stereopsis. Vision decreased (mean from 0.02 logMAR to 0.25 logMAR) and stereopsis declined significantly (mean from 40 s to 60.2 s of arc) when Gx > 0.1 g. Visual acuity worsened (mean from 0.02 logMAR to 0.19 logMAR) and poor stereopsis was noted (mean from 40 s to 50.2 s of arc) when Gy > 0.1 g. The effect of acceleration from the X-axis on the visual system was higher than that from the Y-axis. During acceleration, most subjects complained of ocular strain when reading. To our knowledge, this study is the first to report the exact levels of visual function loss during Gx and Gy.

“…In motion sickness studies, often a portion of participants show no effect to the provocative stimulus (see e.g. Dong et al, 2011;Perrin et al, 2013). This can be seen in Fig.…”

Looking forward: In-vehicle auxiliary display positioning affects carsickness

Carsickness is associated with a mismatch between actual and anticipated sensory signals. Occupants of automated vehicles, especially when using a display, are at higher risk of becoming carsick than drivers of conventional vehicles. This study aimed to evaluate the impact of positioning of in-vehicle displays, and subsequent available peripheral vision, on carsickness of passengers. We hypothesized that increased peripheral vision during display use would reduce carsickness. Seated in the front passenger seat 18 participants were driven a 15-min long slalom on two occasions while performing a continuous visual search-task. The display was positioned either at 1) eye-height in front of the windscreen, allowing peripheral view on the outside world, and 2) the height of the glove compartment, allowing only limited view on the outside world. Motion sickness was reported at 1-min intervals. Using a display at windscreen height resulted in less carsickness compared to a display at glove compartment height.

“…This prediction may allow engaging various compensatory actions, such as tilting the head to align with the tilted gravitoinertia, therefore minimizing the lateral oscillations, a behavior often observed in the drivers ( 161 ). Accordingly, motion sickness in rally co-drivers varies considerably as a function of the specific activity, which may involve different levels of interaction with the driving and the environment ( 162 ). A recent study, asking the passenger to actively align the head to the gravitointertia, mimicking therefore the driver’s behavior, showed a significant reduction in motion sickness with respect to normal seating with the head upright ( 163 , 164 ).…”

Moving in a Moving World: A Review on Vestibular Motion Sickness

2016

View full text Add to dashboard Cite

Motion sickness is a common disturbance occurring in healthy people as a physiological response to exposure to motion stimuli that are unexpected on the basis of previous experience. The motion can be either real, and therefore perceived by the vestibular system, or illusory, as in the case of visual illusion. A multitude of studies has been performed in the last decades, substantiating different nauseogenic stimuli, studying their specific characteristics, proposing unifying theories, and testing possible countermeasures. Several reviews focused on one of these aspects; however, the link between specific nauseogenic stimuli and the unifying theories and models is often not clearly detailed. Readers unfamiliar with the topic, but studying a condition that may involve motion sickness, can therefore have difficulties to understand why a specific stimulus will induce motion sickness. So far, this general audience struggles to take advantage of the solid basis provided by existing theories and models. This review focuses on vestibular-only motion sickness, listing the relevant motion stimuli, clarifying the sensory signals involved, and framing them in the context of the current theories.
