A userâs free hands provide an intuitive platform to position and design virtual menu interfaces. We explore how the hands and eyes can be integrated in the design of hand-attached menus. We synthesise past work from the literature and derive a design space that crosses properties of menu systems with an hand and eye input vocabulary. From this, we devise three menu systems that are based on the novel concept of Look & Turn: gaze indicates menu selection, and rotational turn of the wrist navigates menu and manipulates continuous parameters. Each technique allows users to interact with the hand-attached menu using the same hand, while keeping the other hand free for drawing. Based on a VR prototype that combines eye-tracking and glove-based finger tracking, we discuss first insights on technical and human factors of the promising interaction concept.
