Tiled-monitor large displays are widely used in various application domains. However, how their interior bezels affect user performance and behavior has not been fully understood. The authors conducted three controlled experiments to investigate effects of tiled-monitor interior bezels on visual search, straight-tunnel steering, and target selection tasks. The conclusions of their paper are: interior bezels do not affect visual search time nor error rate; however, splitting objects across bezels is detrimental to search accuracy and interior bezels are detrimental to straight-tunnel steering, but not to target selection.
