“…Such tasks may actually reduce susceptibility if they curtail other behavior. By contrast, tasks that make demands on perception-action interactions with the environment, such as visual search, often increase susceptibility (Benson & Guedry, 1971;Guedry, Benson, & Moore, 1982).…”

“…Guedry et al [17] found that the whole-body angular oscillation of 2.5 Hz ( ± 20 0 peak velocity) degraded the visual search task, but did not produce signs and symptoms of motion sickness with in a 5 minutes exposure. Sherwood and Griffin [18] suggested that the vibration disrupts central cognitive mechanisms utilized during the processing of information in short-term memory.…”

This paper presents a study in which the effect of noise and vibration on the task performance in a mobile driving environment is experimentally investigated. A readability kind of task, where a reading material was presented to the operators on a laptop screen was considered and the operators performed the task in a sitting posture without their back supported with the backrest of the seat. The task performance was measured in terms of mean number of characters read per minute by the operators, which served as data for statistical analysis. Results of the study showed that noise and vibration were statistically significant. The interaction between gender and vibration was also found to be significant. The presence of noise and vibration in a mobile environment decreased the operators' task performance. The results of the simple main effect analysis indicated that the gender was statistically significant for the last two levels of vibration. However the equivalent acceleration of vibration was found statistically significant for males and females. The findings are in line with previous researches that showed negative significant effect of noise and vibration on operators' task performance.

“…In those tests, the constant yaw velocities are selected to not provoke motion sickness. About 0.02 Hz yaw oscillation at 155 • /s peak velocity provokes motion sickness, but not 2.5 Hz at 20 • /s peak velocity, when the subjects simultaneously try to find a certain value in a head fix matrix display [21]. No description of the seat was provided in the report.…”

Carbody tilting is today a mature and inexpensive technology that allows higher speeds on curves, thus shortening travel time. The technology has been accepted by many train operators, but some issues are still holding back the full potential of tilting trains. This paper focuses on improving the benefits and limiting the drawbacks of tilting trains. This is done by quantifying the possible running time benefits compared with today's tilting trains, identifying what motion components have an influence on motion sickness, and finally quantifying the influence from the increased speed on these motion components. A running time analysis was made to show what potential there is to further improve running times by optimizing tracks and trains. Relations between cant deficiency, top speed, tractive performance, and running times are shown for a tilting train. About 9 per cent running time may be gained on the Stockholm-Gothenburg (457 km) main line in Sweden if cant deficiency, top speed, and tractive performance are improved compared with existing tilting trains. Introduction of non-tilting high-speed trains is not an option on this line due to the large number of 1000 m curves. However, tilting trains run a greater risk of causing motion sickness than non-tilting trains. Roll velocity and vertical acceleration are the two motion components that show the largest increase, but the amplitudes are lower than those used in laboratory tests that caused motion sickness. Higher curve speeds will increase carbody motions still further, but there are some possibilities to trade between vertical and lateral carbody acceleration by increasing or decreasing roll.
