A novel user interaction system combining an aerial display and a gesture interaction is expected to provide an excellent user experience. However, its psychometric effectiveness has not been sufficiently explored. In this reported study, we performed a usability test of the system that comprised an aerial display, gesture interaction, and suitable software content. Using a statistical analysis employing the Kruskal Wallis test and a factor analysis of the experimental results, the importance of a suitable combination of aerial display and gesture interaction as well as the novelty of the aerial display were demonstrated. Following this, a two-dimensional aerial display was considered to be adequately useful for a typical spatial user interaction system.
