Supply and Demand: Perspectives on Mental Workload with Consumer Products
Workload is one of the most widely used concepts in human factors (Flemisch and Onken 2002). Yet it is also one of the most nebulous concepts, with numerous de™nitions and dimensions associated with it. Moreover, research in this area has a tendency to focus on complex, often safety-critical systems (e.g., transport, process control). This chapter takes us beyond the usual suspects of humans in control, and looks instead at how mental workload (MWL) affects everyday interactions with consumer products, and what lessons we might apply to product design.
