Abstract
  • This study describes an eye tracking experiment conducted at the Interaction Design Lab of UNC-CH. This experiment focuses on identifying and analyzing user behavior and patterns when processing numeric table data in paper or PDF format. Eight sets of eye data were collected using the ASL 504 eye tracking system, and raw data were analyzed using EYENAL and FIXPLOT software. Statistical literacy and familiarity with tables is an important factor in determining users' search performances. For both formats, table column and row headings account for nearly half of users' visual attention during search as as measured by fixation duration. In large tables, PDF files do not appear to be appropriate for browsing and searching, and footnotes seem hard to use. Simple manipulations over table data are helpful for users to get a better understanding of statistical tables.
