Scanning Between Graph Visualizations: An Eye Tracking Evaluation
From BELIV 2010
Presentation
Notes
- good for micro level design issues, surgical tool after people have done a usability evaluation
- mouse? talk? recruit different number of people
- difficult to do eye tracking on rich client interfaces
- data? qual or quant?
- heatmaps? great for first short term, more interested in temperate changes, can we extract scanning strategies
- (started talking about studies)
q and a:
- problems solved with statistics
- visual stimuli are so small; arms length can see a thumbnail width (couple of cms on the screen), need buffer area on the AOI
- strategies between spider / bar graphs, when a scanpath differ? reading across a graph and scanning between dimensions, when id different enough for paths to be different? hierarchical clustering to find strategies.
- which chart types? it depends, very task dependent
- automatically select graph types depending on a task
- interactive vis? interactive UI, accordance, or simple menu, take a movie and look at segment of movies, love to have a video based tool, not impossible
