HCI

Which is an appropriate statement about a system's HCI quality?

A system's HCI quality depends on the overall effects from the system in many different human concerns;

GOMS - generic term used to refer to a family of models that vary in their granularity concerning the aspects of the user's performance they model and make a prediction about
