could be performing a variety of tasks that could be directly related to the control of
the vehicle, or could be something unrelated to the vehicle. There is potential for
the exposure to WBV whilst performing a task to adversely affect task performance.
This paper uses two case studies to illustrate a model of performance and workload
whilst exposed to vibration. It is shown that performance whilst completing a
discrete task (Purdue pegboard) is easily affected by vibration, but a continuous
task (steering wheel) is unaffected. However, in both cases, the self-reported
workload increases with vibration. A model is presented that shows that where
there is adaptive capacity of the operator, they are able to compensate for the
vibration with greater control but at the cost of workload. However, beyond a
coping threshold the performance will degrade.
