C-TOC Meeting Minutes - April 30, 2010

• Attendees: Joanna, Claudia, Sarah, Matt

Minutes

Upcoming

• cross- cultural advisory panel - May 27 10-1 in Coquitlam (further meetings Oct 2010, Jan 2011) - verbal similarities and memory assessment tests
• 1st iteration user evaluation and interview - starting week of May 15 (1 subject confirmed, 1 tentative, 5 total)

Development

• prototype - interactive powerpoint prototype largely ready for user testing (1st iteration)
• drag. + drop vs. point and click?
• stock photos

Test Battery

• see previous meeting minutes March 11
• vis. similarities, pattern construction / recall, sentence production
• added value for lengthy tasks in the battery?
• hippocampal associative memory - misplaced item test - recall + identification - more than one clickable object needed; allow 2nd try on recall task? see Sarah's notes
• timing the tests - counter/no-counter - count upwards from zero / clock icon - no timer icon necessary? appropriate to time all tests - remove timer from tests
• visual acuity / colour perception - forced-choice/JND task
• motor accuracy + speed test (Fitts' law layout / pegboard test)
• visual reproduction task indicative of early dementia - field neglect
• feedback in arithmetic task required
• test interruption / resumption - "are you still there?" prompt after threshold time elapsed of inactivity - how to determine when a test performance is invalid due to inactivity? (time between encoding and recall portions of tests)
• need to establish validity for single tests and entire battery
• HCI question of how to keep people on task, who is most likely to have problems staying on task, how is this a function of cognitive impairment, what types of impairment are associated with the greatest difficulties of staying on task?
• if test interruptions are unavoidable, a possibility is the use of a proctor, required to sign in before the examinee and promise to remove distractions and keep the examinee on task - online testing (i.e. boating licence exam)

To do:

• Kori Inkpen - drag+drop vs. point+click - differences between older users / children - must be consistent
• Karyn Moffat - Ph.D thesis - reference - performance differences between 5 wordings of speed/accuracy task instructions (Fitt's task)
• review papers for clinical diagnoses / conditions (Claudia)
• ongoing Lit Review
• making the prototype fully interactive
• interviews need to contain HCI component
