5. How does a human operator time share between tasks? Normally, the driver performs
many tasks while driving and shares resources (e.g., sensors located in different parts of
visual elds or different sense modalities) between different tasks (e.g., driving and listen-
ing to the radio or talking to other passengers). Due to limitations in capabilities of the
information-processing resources, the driver generally attends to the important tasks and
disregards other lesser priority tasks.
6. How does the driver select what he or she should attend to? The driver must be processing
