- "click to pick up; move; click to drop" is "pretty stupid" (tried to do regular drag-and-drop despite instruction); should this be clearer somehow? we should likely abandon point-and-click;
- potentially a good test to see if user is reading carefully or just skimming
- help menu fine
- "highest grade achieved" ambiguous
- tests should potentially be easier at home due to comfort in one's own environment
- TO: need a different arrangement of dates in grid view to be shown
- SDM: clicking directly on numbers required, numbered boxes not yet interactive (PPT limitation?)
- SIM: automated navigation / slide advancement would be intuitive, "like the Mac"
- PC: "click to pick up; move; click to drop" still frustrating, but getting used to it; PC difficult due to diagnosis
- "Done" bttn unnecessary, expecting automated advancement b/w trials;
- easier on a computer, but sometimes forgot instructions, tried as fast as possible
- Trails: people will try to click anyways; ignore? force a click?
- Arithmetics: "better than counting backwards by sevens"
- PR: "?" distracting, have nothing on screen instead
- MOS: "don't understand, have to go back to beginning" "I'm not supposed to click "give up""?
- use automated advance or prompt to click?
- tendency to drag/drop
- after clicking, big object appears: "not sure what to do next"
- SP: couldn't edit the sentence once started, sentences short, assembled quickly; would want to move / select multiple words, like on a Mac
- initially occluded other word in the grid
- not sure what it is measuring
- SqP: macro bug (difficulty dropping, keeping it in place)
- GS: confusing title - mouse moved away during target word to get next word to appear quicker; instructions unclear? "could be made harder"
- MOR: tendency to drag misplace object into scene; potentially into drop zone?
- overall:
- willing to take test again
- include emotional perception test
- would like to know that results will not be shown before test being
- would shut out everyone from house, all distractions to set up testing environment;
|
| test fixes/suggestions: |
|
> > |
- provide more practice using "click to pick up; move; click to drop" or use conventional drag-and-drop
- inform that results will not be shown at end before test being
- SP: add ability to place words between existing words, move multiple words at once
- throughout: automated slide advances or prompts to advance; visible navigation buttons at all times;
- Trails: force a click to move to next symbol
- GS: changed Go-Stop name

Notes: |
|

- intro: "next" cloud on first screen, thought to click there
- also has conventional drag-drop habit
- PWP: would need additional prompts to click forward
- stuck at beginning, wrt instructions
- would be more comfortable at home, performing better on test and recall
- SDM: had to trace mouse from prompt to response
- "this is the way to go", more comfortable
- SIM: instructions should be above options
- thought that no feedback was a mistake in design, less comfortable and reassuring, more difficult
- WR: clicking on text is first instinct, not in #'d box
- PC: difficulty w/ puzzles - bug in practice test - instruction box cannot be used as drop zone
- "target" should read "desired", "reproduce blue pattern w/ green shape"
- a clock would induce anxiety
- SC: "correct" message reassuring
- note enough room for lining shapes up from smallest to largest (vertical rather than horizontal);
- "I felt doubt", forgets instructions
- Trails: automatic line appearance unexpected, tried to drag lines
- notion of speed took him off guard
- done before on paper
- MOS: didn't realise object would reveal itself
- provide lures and +/- feedback for context-appropriate items?
- pleasant to see actual feedback
- SP: "finding this very difficult", not a word person
- GS: would be exciting to have a stopwatch on screen;
- bug after "Sorry, Try Again" - broken links
- appropriately challenging, but in a fun way
- MOR: difficult without feedback
- overall: provide opportunity to go back a page;
- images were pleasant, could have had more
- "perfectly OK", on edge of fatigue
- provide a "thank you slide", a reward in finishing
|
| test fixes/suggestions: |
|
> > |
- intro: more practice w/ "click to pick up, move, click to move"
- PC: fix instruction box drop zone bug in practice trial
- Trails: force clicking rather than mouse-over?
- MOS: context-appropriate lures?
- GS: fix broken link bug after "Sorry, Try Again"
- throughout: ability to go back a page, where appropriate or permitted
- overall: a "thank-you slide"
