Question

Why are most design rules for interactive systems more suggestive and general?

a.

To make them easier to implement in actual design.

b.

Due to the abstract nature of the underlying design theories.

c.

To ensure compliance with national or international standards.

d.

Because they are applicable only to hardware design.

Answer: (b).Due to the abstract nature of the underlying design theories. Explanation:The incompleteness of the theories underlying the design of interactive software makes it difficult to produce authoritative and specific standards. As a result, most design rules are more suggestive and general, as the underlying theories are less well-formed and fixed.
