Beyond system logging: human logging for evaluating information visualization
From BELIV 2010
Presentation
Notes
- some uncertainty: min/max cog load--put all of them together, frustration + load, not good; pleasure + load, good
- strategies: how to approach; med imaging to see how people read xrays to teach students how to read it (eg concentrating on some points on the xray)
- is there one or two that is more promising in the short time that we should look at more: no, add them all of them, correlation between all of them will give us the answer, triangulation; eye-tracking is easier to analyze right now; if got significant results, see in physiological measures, if not, hard to see signals
- wear many gears? for now, but yes, have to start somewhere
- ind differences? for each person, 90% effective with training, it's a within subject thing
- multidimensional understand, most measures are correlated, some may be impact by parasympathic/sym activities, going to take many years before one can tease these apart; same as interview, don't try to do it and look at the data to find something, start with hypothesis to verify, esp with significant results from other studies
- brain activity, can we provide some visual stimuli systematically generate insights, can catch them or not? tricky problem
