An empirical study of virtual reality menu interaction and design

This study focused on three different menu designs each with their own unique interactions and organizational structures to determine which design features would perform the best. Fifty-four participants completed 27 tasks using each of the three designs. The menus were analyzed based on task performance, accuracy, usability, intuitiveness, and user preference. Also, an analysis was conducted between two different menu organization styles: top-down menu organization (Method-TD) and bottom-up organization (Method-BU). There was no evidence that demographic factors had any effect on the overall results. By and large, the Stacked menu design received very positive results and feedback from all the participants. The Spatial design received average feedback with some participants preferring it while others struggled to use it and felt that it was too physically demanding. The worst performer was the Radial design that consistently ranked last and failed to pass usability and accuracy tests. A NGOMSL study was conducted to determine any differences in performance between a top-down menu organizational approach and a bottom-up approach or differences between the predicted task completion times and the reported times. The results of this study predicted that the Spatial design should have taken the least amount of time to perform, however, the experimental results showed that the Stacked design in fact out-performed the Spatial design’s task completion times. A potential explanation as to why the Stacked outperformed the Spatial is the increased physical demand of the Spatial design not anticipated with the NGOMSL analysis because of a design feature which caused a high level of cumbersomeness with the interactions. Overall, there were no statistical differences found between Method-TD and Method-BU, but a large difference found between the predicted times and observed times for Stacked, Radial, and Spatial. Participants overwhelmingly performed better than the predicted completion times for the Stacked design, but then did not complete the tasks by the predicted times for the Radial and Spatial. This study recommends the Stacked menu for VR environments and proposes further research into a Stacked-Spatial hybrid design to allow for the participant’s preferred design aspects of both designs to be used in a VR environment.
