26 26 Almost all were missing… Any plan for pilot testing!!!! Any plan for pilot testing!!!! –When will you do pilot testing? (at least a day for modifications before collecting real data) –How many pilot subjects? (at least one, but a couple would be better) –Will be looking for how you pilot tested, changes you made in final report Go Stanford!

27 27 More detail on user study Need to think specifically about user tasks Need to think specifically about user tasks –What is starting point? –Script of what you are asking them to do Write out questions for survey Write out questions for survey –If Likert scale, also write out anchors
