The DBN is used to extract the high-level workload features from the past VM resource utilizations, while the regression layer is used to predict the future load values.
A rating of 0 reflects a very low level of workload and a rating of 21 reflects a very high level of workload.
A rating of 0 reflects a very low level of workload and a rating of 21 reflects a very high level of workload Fig. 8 Mean NASA TLX ratings for the six sub-scales for the first testing day (Session 1) and the last testing day (Session 2).
A rating of 0 reflects a very low level of workload and a rating of 21 reflects a very high level of workload Fig. 9 Mean NASA TLX ratings for the six sub-scales in the younger, middle, and older age groups.
In the health centres, the situation was better, but the staff still experienced a high level of workload and responsibilities due to absenteeism (see Table 2).
The analysis of workload using the on/off task DRT data found that "on-task" performance was associated with surprisingly high levels of workload (i.e., averaging 3.34 on our 5-point scale).
The impact of these voice-based commands on the motorist's cognitive workload is unknown; however, voice-command laboratory surrogates with perfect reliability have been shown to produce surprisingly high levels of workload (Strayer, Cooper, Turrill, Coleman, & Hopman, 2015a, Strayer et al., 2015b).
Human users dealing with multiple objectives in a complex environment (e.g., military planners or emergency response operators) are subject to a high level of cognitive workload.
These findings reflect a moderate to high level of cognitive workload.
The overall workload ratings associated with IVIS interaction averaged 3.34 on our 5-point scale and ranged from 2.37 to 4.57; this reflects a moderate to high level of cognitive workload.
The higher level of workload should serve as a caution that these voice-based interactions can be very mentally demanding and ought not to be used indiscriminately while operating a motor vehicle.
