Volumetric Interaction (VI) is a promising new paradigm for virtual reality (VR) that seeks to create more intuitive experiences by allowing users to interact utilizing their body volume. This research evaluates a VI prototype in which users manipulate a virtual balloon using volumetric properties obtained from real-time SMPL mesh reconstructions of their bodies. We present a prototype VR application in which users manipulate a virtual balloon using the momentum generated from their chest or torso, and we assess its practicality and usability using a small-scale user study. Results demonstrate the potential of VI for embodied VR interaction, highlighting faster task completion with torso-based control. While usability evaluations reveal areas for improvement in control sensitivity and predictability, this work establishes a foundation for future research into volumetric properties as a rich modality for immersive and intuitive VR experiences.
