AgileFingers: Authoring AR Character Animation Through Hierarchical and Embodied Hand Gestures

We present AgileFingers, a hand gesture-based solution for authoring AR character animation based on a mobile device. Our work initially categorizes four major types of animals under Vertebrata. We conducted a formative study on how users construct hierarchical relationships in full-body skeletal animation and potential hand structure mapping rules. Informed by the study, we developed a hierarchical segmented control system, which enables novice users to manipulate full-body 3D characters with unimanual gestures sequentially. Our user study reveals the ease of use, intuitiveness, and high adaptability of the AgileFingers system across various characters.
