	=== thursday class notes ===		=== thursday class notes ===

			* give my practiced 2-minute Ernestine presentation from notes:
			** just like the proposal, this paper used a model of human behavior to estimate task time for phone operators
			** task was completing an operator-assisted call
			** tried 2 different user interfaces -- old and new
			** first tried GOMS (Goals, Operators, Methods, Selection) to describe human tasks, but it didn't account for our ability to do multiple things at once
			*** eg talk to you while I move my hand to the board
			** then CPM-GOMS (adds Cognitive, Perceptual, Muscle) to get parallelism
			*** each type of operation, C, P, M, can proceed in parallel
			** they got results that compared the two user interfaces accurately and matched real user studies that were also done for both interfaces
			** relates to proposal because it does same thing and illustrates many of the difficulties and complexities


			* critique that presentation
			** what was good?
			*** goals for presentation
			**** related to our research
			**** fit in 2 minutes
			**** indicate further directions
			** what could have been improved

			* should we discuss this further?
			** 5: yes, 4: maybe, 3: if we have nothing else to do, 2: no, 1: I'll leave if we do
			** go around table starting at my left

			* practice
			** how many practiced their presentation? Hold up as many fingers as the number of times you practiced:
			** pair up, spread out,
			*** 2:00 present to other person
			*** 2:00 other person provide feedback afterward
			*** 2:00 revise your notes
			*** 2:00 repeat
			*** 2:00 other person provide feedback afterward
			**** 10:00 swap

			* go through actual papers
			** 25:00 with discussion scoring after each one

			** Caroline: Cognitive strategies and eye movements for searching hierarchical computer displays
			*** lots of "what"
			*** validate intuitions about searching (proove hypotheses?)
			*** "EPIC" architecture (like CPM_GOMS)
			*** eye-tracking works
			*** what model? what problems? how could we use it? What projects could we do with it? what would we need to do them?
			** van Wedeen paper
			*** mapping whole-brain structure
			*** project is about visualizing this information (picture would be great)
			*** use as a semi-automated starting point for high-level regions?
			*** lots of "what" and comparison to other similar methods
			*** missing is visual analysis (makes a case for us to use it in our application)
			*** network

			** Steve: theory of fluid visualization
			*** is interesting, built up author as expert, position paper
			*** two pieces: first describes how to use perceptual theories to predict human perforance
			*** second: define tasks, construct tasks, iterate over mappings
			*** limitation: no specific experiment (but does have experiments that come in the future)
			*** dhl: nice acks (me, caroline's advisor :-)
			*** dhl: a theory for part of the low-level perceptual human behavior

			** Michael: forearm electromyography
			*** demonstrates that forearm modeling can be done as part of a UI
			*** lots of "what"
			*** freeing up hands could help users be more efficient
			*** shortcoming: doesn't address the issue of cognition (a bit of a stretch in addressing)
			*** dhl: slightly tangential, perhaps, but could use as human data capture (like eye tracking and fNIRS and event tracking...)


			** (no owner): intent to speak


			** diem: fNIRS, your brain on interfaces (brain heat imaging)
			*** another human measurement, maybe of brain load

			** Hua: effectiveness of graph visualizations
			*** concept of mental effort and evaluation of it
			*** response time relationship to mental effort -- combines them
			*** "mental effort" concept -- could we use it? goes to a higher level than muscle motions (other kinds of measures?)


			** Clara: visual attention review
			*** experiment about how quickly users can adjust to confusing layouts
			*** results are relevant as guide for designing HCI
			*** eye-tracking treatment in the paper relevant to our use potential use of eye tracking
			*** dhl: nice staging metaphor -- user experience: guide, but subtly
			*** dhl: covert attention -- cool
			*** dhl: all read this in more detail?


			** Jenna: color scale
			*** tasks will be similar to what their experiments tested
			*** speed-accuracy tradeoff in use of color
			*** specific guidelines for using color

			** nathan: computational visual attention systems
			*** overt and covert visual attention
			*** what models there are for visual attention
			*** vision and robotics applications
			*** should be applicable to visualization, too -- knowing what folks are looking at should be good at predicting where we are showing too much or too little


			** Chen: wizard of oz for gestural interface for 3D selection of neural pathway estimates
			*** good design process to emulate

			** Wenjun: maeda book
			*** minimalist design
			*** managing complexity is simplicity
			*** dhl: could we figure out how this connects to cognition
			*** illusion of waiting -- can be frustrated
			*** put more emotion into design


			* discussion of winner(s)
			** this will carry forward into next class, too

			* moving forward
			** format ok? longer presentations? shorter?
			** another week like this one but more informed?
			** a week reading everything from one conference?
			** something else?
