Question

In the PIE model, what is the role of the "effect" (E)?

a.

To represent the current internal state of the system

b.

To serve as the display screen of the system

c.

To calculate the user's input history

d.

To account for the future external behavior of the system

Posted under Human Computer Interaction

Answer: (d).To account for the future external behavior of the system Explanation:The "effect" (E) in the PIE model represents an idealized minimal state required to account for the future external behavior of the system. It is used to calculate the current outputs of the system, which are the display and result.
