Preferences for unfavorable external representations in interaction with ATMs and multimedia

Security codes accompany almost every new multimedia device. The codes are commonly represented in the form of symbolic numbers. The relative usefulness of symbolic and visuo-spatial representations of codes was investigated, using ATM-codes as an enlightening example. Visuo-spatial representations lead to higher performance on an immediate recall test. This suggests that explicit visuo-spatial representations in multimedia design may enhance usability. In spite of these results people showed preferences for the more frequently used numerical representations.
