Formatted abstract This thesis examines the relationship between the human-computer interface and user performance. It was proposed that users of Graphic User Interfaces would perform better than users of Menu interfaces. The relationships between user experience, user attitude, the human-computer interface, and user performance were also examined.

A controlled laboratory experiment was conducted to collect data. The experiment was undertaken at the Queensland Police Academy, with police recruits as participants. An unexpectedly high rate of participant dropout (over 50%) reduced the power of the experiment.

No results were statistically significant. However, the hypothesised relationships between HCI and user attitude, and between user experience and user performance were in the predicted direction. The results of the thesis provide a starting point for questioning the consensus that GUIs produce the best user performance.
