Abstract
Acoustic levitation, or acoustophoresis, is an emerging technique that uses ultrasound waves to suspend and manipulate objects in mid-air. This technique shows great potential and versatility across various fundamental scenarios in the field of Human-Computer Interaction (HCI), including physical displays, contactless delivery, mid-air interactions, etc. However, acoustophoresis is currently in the proof-of-concept phase, and advancing it requires both overcoming fundamental technical challenges and fostering interdisciplinary collaborations to integrate it effectively into diverse application domains. To this end, my research is dedicated to advancing the technology trigger of acoustophoresis by developing computational solutions that can be leveraged to conceptualize and prototype innovative applications. Specifically, this thesis first explores algorithmic solutions to enable reconfigurable and stable acoustophoretic systems. The proposed motion planning and data-driven approaches tackle key challenges while improving the acoustophoretic interface's robustness and facilitating application prototyping. Next, I focus on applying acoustophoretic interfaces to three distinct application scenarios across multi-sensory modalities. For data physicalisation, I demonstrate a design space and implementation platform that enables dynamic, reconfigurable, multimodal physicalisation artifacts with enhanced materiality. Blending with computational gastronomy, acoustophoresis innovates versatile functionalities for food processing and fabrication. With user validation, acoustophoretic manipulation and modulation can deliver chemical stimulants and enhance mixed chemical and mechanical haptic perception. Lastly, I reflect on all the research pathways and outputs, providing a cohesive theoretical framework for the future development of acoustophoresis. In summary, this thesis pushes the design and technical boundaries of acoustophoretic interfaces for interactive applications, transforming and enriching existing interaction systems, tools, and methodologies. By offering valuable insights for researchers, designers, and creators, it not only makes acoustophoretic interfaces more accessible beyond HCI, but also holds the potential to revolutionize industries, and redefine how people engage with the world.
