Q6 | Which of the following is a design implication of our understanding of human attention?
- tactile feedback should make the same kinds of distinctions that a
person would feel in the world (e.g. pushing vs. pulling) - text should be legible and distinguishable from its background under
differe nt lightingconditions. - avoid cluttering the interface with more information than is needed at
the present moment for the user. - none of the above.

- all of above
Q12 | Regarding the measurement of usability attributes:
- reliability is measured by performing common use cases
