Abstract
Virtual and augmented reality (VR, AR) systems present 3D images that users can interact with using controllers or gestures. The design of the user input process is crucial and determines the interactive efficiency, comfort, and adoption. Gesture-based input provides a device-free interaction that may improve safety and creativity compared to using a hand controller while allowing the hands to perform other tasks. Microgestures with small finger and hand motions may have an advantage over the larger forearm and upper arm gestures by reducing distraction, reducing fatigue, and increasing privacy during the interaction. The design of microgestures should consider user experience, ergonomic principles, and interface design to optimize productivity and comfort while minimizing errors. Forty VR/AR or smart device users evaluated a set of 33 microgestures, designed by ergonomists, and linked them to 20 common AR/VR commands based on usability, comfort, and preference. Based primarily on preference, a set of microgestures linked to specific commands is proposed for VR or AR systems. The proposed microgesture set will likely minimize fatigue and optimize usability. Furthermore, the methodology presented for selecting microgestures and assigning them to commands can be applied to the design of other gesture sets.
