Multimodal Workload Monitoring
The cognitive workload can be defined as the physical or mental requirements associated with a task or combination of tasks [13]. On the one hand, the physical workload is the measurable portion of physical resources expended when performing a given task, and it is affected by a range of factors such as nature of work, training, motivation, and environmental factors. On the other hand, cognitive workload reflects the mental strain resulting from performing a task under specific environmental and operational conditions, considering the capabilities of the operator to respond to those demands [10].
