TL;DR: When selecting hierarchical menus with hand gestures, the error rate is significantly higher than when using a desktop environment or controllers. Consequently, UI designers will be able to create more effective user interfaces if they can assess the difficulty of a hierarchical menu design. We present a validated index for estimating the hierarchical menu selection error with hand gestures and head-gaze as input modalities.
