It informs the understanding of the user's mental model

2

Fitt’s Law models the difficulty of selecting graphical objects in an interface based on the assumption that

Different pointing devices have different timing constants

3

Several usability measures can be collected while observing users interacting with a computer system including

Number of user errors

4

An evaluation technique that is more realistic than other methods

Observation

5

An evaluation method that does not require human participants serving as test users is the

Controlled experiment

6

Hicks law states that Reaction Time will increase logarithmically as the:
