Even if the visual and motion cues could be synchronised perfectly, or the visual display were turned off completely, driving over some terrain at certain speeds will produce movement patterns that will result in motion sickness in some trainees. Thirdly, anecdotal reports indicate that the TDT visual display will produce simulator sickness symptoms that are related to eyestrain if the trainee stares at one of the three terrain displays. Several points can be made about the methodology of measuring simulator sickness. Based on the findings presented above, ARI presented several recommendations to the commander, 1st Armour Training Brigade. For the five scenarios with the highest incidence of simulator sickness consider replacement, modification, modification of how the scenarios are used, or presentation later in the POI when trainees are less likely to experience simulator sickness.
Decrease stresses affecting trainees on their first TDT training session.
The rationale for this last recommendation is that in field training it is to be expected, and sometimes required, that trainees will be fatigued or otherwise stressed during training. In addition to lack of sleep, trainees are under additional stress in that they hear rumours that the TDT will make them vomit. In addition, until recovered, the trainee should not be required to drive any real-world vehicle. The TDTs provides initial and transition driver training for M1 Abrams tank crewman. The instructor station is capable of selecting a visual scene, viewing it, monitoring each trainee's performance and introducing malfunctions and emergency control situations.
