The increasing use of 3D user interface elements, particularly 3D menus, demonstrates the need to expand research in the field of Human Computer Interaction (HCI) as it pertains to 3D user interfaces. The results of this thesis contribute to the understanding of the cognitive impacts of using 3D menus. Multiple application areas for 3D menus have been identified where memory retention is a critical success factor, but little research has been done in the area of memory retention for 3D menus. The purpose of this thesis is to investigate if the use of 3D carousel menus increases retention of information over 2D menus and if is there a gender effect with these results. A three factor split-plot (one-between subject factor and two-within subject factors) experiment was designed to test if menu dimension, content type, and gender are significant factors in memory retention and to determine if there are any interactions between these factors. The results of the experiment revealed that dimension and gender are not significant factors in the retention of information and none of the interactions of dimension (2D vs. 3D), gender, and content were significant. Several subjects’ questionnaire responses demonstrated that the menu dimension they perceived to better aid retention was 3D; however these results were not statistically significant. While these results showed that within the boundaries chosen the use of a 3D menu neither promotes nor degrades memory retention, there are still a number of questions that need to be answered regarding the use of 3D menus and their effect on other cognitive processes.
