Recently, eye\n   tracking has also become popular to analyze visual strategies of users\n   in this context. This has added another modality and more data, which\n   requires special visualization techniques to analyze this data. However,\n   only few approaches exist that aim at an integrated analysis of multiple\n   concurrent evaluation procedures. The variety, complexity, and sheer\n   amount of such coupled multi-source data streams require a visual\n   analytics approach. Our approach provides a highly interactive\n   visualization environment to display and analyze thinking aloud,\n   interaction, and eye movement data in close relation. Automatic pattern\n   finding algorithms allow an efficient exploratory search and support the\n   reasoning process to derive common eye-interaction-thinking patterns\n   between participants. In addition, our tool equips researchers with\n   mechanisms for searching and verifying expected usage patterns. We apply\n   our approach to a user study involving a visual analytics application\n   and we discuss insights gained from this joint analysis. We anticipate\n   our approach to be applicable to other combinations of evaluation\n   techniques and a broad class of visualization applications.","annote":"","author":[{"family":"Blascheck","given":"Tanja"},{"family":"John","given":"Markus"},{"family":"Kurzhals","given":"Kuno"},{"family":"Koch","given":"Steffen"},{"family":"Ertl","given":"Thomas"}],"citation-label":"ISI:000364043400011","collection-editor":[],"collection-title":"","container-author":[],"container-title":"IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["{2016}","JAN"]],"literal":"{2016}"},"event-place":"10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA","id":"cc131f8c378577ab621d7a274ca4c61dhermann","interhash":"5effcc98e8efb3870ffb9ba9a527edfb","intrahash":"cc131f8c378577ab621d7a274ca4c61d","issue":"1","issued":{"date-parts":[["{2016}","JAN"]],"literal":"{2016}"},"keyword":"analytics; evaluation; tracking; aloud; {visual logs; eye thinking qualitative series time interaction data}","misc":{"author-email":"{tanja.blascheck@vis.uni-stuttgart.de\n   markus.john@vis.uni-stuttgart.de\n   kuno.kurzhals@virus.uni-stuttgart.de\n   steffen.koch@vis.uni-stuttgart.de\n   thomas.ertl@vis.uni-stuttgart.de}","issn":"{1077-2626}","keywords-plus":"{EYE FIXATIONS; VISUALIZATION; INSIGHT; METHODOLOGY; MOVEMENT; SEARCH;\n   TOOL}","funding-acknowledgement":"{German Federal Ministry of Education and Research (BMBF); German Science\n   Foundation (DFG) {[}(SPP) 1335]}","research-areas":"{Computer Science}","eissn":"{1941-0506}","number-of-cited-references":"{52}","affiliation":"{Blascheck, T (Reprint Author), Univ Stuttgart, Inst Visualizat \\& Interact Syst VIS, Stuttgart, Germany.\n   Kurzhals, Kuno, Univ Stuttgart, Visualizat Res Ctr, Stuttgart, Germany.\n   Blascheck, Tanja; John, Markus; Koch, Steffen; Ertl, Thomas, Univ Stuttgart, Inst Visualizat \\& Interact Syst VIS, Stuttgart, Germany.}","web-of-science-categories":"{Computer Science, Software Engineering}","funding-text":"{This work has been partially funded by the German Federal Ministry of\n   Education and Research (BMBF) as part of the `ePoetics' project and the\n   German Science Foundation (DFG) as part of the priority program (SPP)\n   1335 `Scalable Visual Analytics'.}","language":"{English}","times-cited":"{4}","doi":"{10.1109/TVCG.2015.2467871}"},"note":"10th IEEE Conference on Visual Analytics Science and Technology (VAST) /\n   IEEE VIS Conference, Chicago, IL, OCT 25-30, 2015","number":"1","number-of-pages":"9","page":"61-70","page-first":"61","publisher":"IEEE COMPUTER SOC","publisher-place":"10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA","status":"","title":"VA(2): A Visual Analytics Approach for // Evaluating Visual Analytics\n   Applications","type":"article-journal","username":"hermann","version":"","volume":"22"}}
