Abstract
Dette studie undersøger, hvordan nybegyndere og erfarne brugere adskiller sig, når de bruger et webbaseret e-mailsystem, og om kendskab til at deltage i brugervenlighedstests påvirker, hvilke problemer der findes. Vi gennemførte to laboratoriebaserede evalueringer: en longitudinel undersøgelse, hvor brugere blev fulgt over to måneder, og en enkeltstående test (et øjebliksbillede). Vi talte antallet og typerne af brugervenlighedsproblemer (hvor let systemet er at bruge) og vurderede, hvor alvorlige de var. Efter to måneders brug af systemet rapporterede brugerne markant færre brugervenlighedsproblemer. Tidligere erfaring med brugervenlighedstests fik ikke deltagerne til at identificere væsentligt andre problemer end førstegangs testpersoner.
This study examines how novice and experienced users differ when using a web-based email system and whether familiarity with taking part in usability tests affects what problems are found. We ran two lab-based evaluations: a longitudinal study that followed users over two months and a one-time snapshot test. We counted the number and kinds of usability problems (how easy the system is to use) and rated how severe they were. After two months of using the system, users reported significantly fewer usability problems. Prior experience with usability testing did not make participants identify significantly different problems than first-time test subjects.
