SoundHolo: Sonically Augmenting Everyday Objects and the Space Around Them
Daniel Rosenberg Munoz · 2025
SoundHolo is a room-scale platform for sonically augmenting everyday objects by dynamically attaching 3D sounds to them and their surrounding space. By integrating wave field synthesis and motion tracking within a 20x30x12 foot room, SoundHolo explores how 3D sounds can augment any object without relying on embedded electronics or personal devices. Augmenting everyday objects with interactive output capabilities is a long-standing topic in HCI research. We contribute by enabling any physical object to emit sound, regardless of shape or material constraints, and allowing public, devicefree experiences. We implemented SoundHolo along with a matrix demonstrating eighteen output variations, offering a palette of design options for HCI researchers developing sonic augmentations. This paper integrates visuals and texts detailing the platform implementation, application scenarios, and preliminary evaluation.
