WP7-Panorama-with-Caliburn.Micro1

  The study consisted of an introduction, three scans performed for each of the eleven scanners, and an adjacent interview. We utilized a within-subject design. The dependent variables were task completion time and reliability, by which we mean the share of successful scans within a task completion time below 15 seconds. The independent variables were the barcode scanners as listed in Table 1. For each participant the study was recorded on video. We also transcribed comments the participant made during the tasks.
