Question

What is the primary focus of the PIE model?

a.

Describing the internal architecture of a computer system

b.

Defining the inputs and outputs of an interactive system

c.

Identifying the specific commands used by users

d.

Formalizing the relationship between display and result

Posted under Human Computer Interaction

Answer: (b).Defining the inputs and outputs of an interactive system Explanation:The primary focus of the PIE model is to define the inputs and outputs of an interactive system, describing it purely in terms of its interactions with the user, including inputs from the user (commands) and outputs to the user (display and result).
