EuroVis2010 Day 3 Wrapup
6:30 pm
This article is the third and final in a series of wrap-ups from VizWorld reader T.J. Jankun-Kelly (@dr_tj) of the EuroVis2010 conference currently underway. If you missed it, see Part 1 and Part 2.
The last day of the conference saw an abbreviated program with two sessions and the plenary. The Best Paper was also awarded. As with the previous day, there were two tracks.
Session 7B: Vectors & Tensors
An Evaluation of Glyph Perception for Real Symmetric Traceless Tensor Properties; T.J. Jankun- Kelly, Yagneshwara Lanka, Edward Swan
This presentation by your humble scribe discussed a perceptual study involving tensors from liquid crystal physics. The motivation was to determine if the glyphs we had previously designed communicated the three perceptual dimensions of the data (orientation, compression/elongation, and flatness) better than other glyphs used by physics. Two users studies involving 30 subjects found that our superquadric tensor glyphs were significantly more accurate in communicating these features; cylindrical glyphs faired the second best with ellipsoids and box-like glyphs following. Similar studies could be performed for other tensor glyphs to determine their efficacy.
