This proposal explores minimalist perception, a design philosophy prioritizing simplicity and efficiency in sensor technology to capture essential information for various applications, including robotics, environmental monitoring, and wearable technology. By focusing on streamlined functionalities, these sensors avoid the complexities and costs of more elaborate systems, offering practical solutions under resource constraints. Our research emphasizes developing low-power, miniaturized systems that integrate seamlessly into both urban and natural environments, enhancing ubiquitous perception without the encumbrance of complex technologies. We explore three main areas: low-power and miniaturized acoustic direction-of-arrival (DoA) estimation, ultra-low-power spatial sensing for miniature robots, and a single frequency-based tracking interface for voice assistants. The contributions include a novel low-power DoA estimation system using 3D-printed metamaterials, an innovative spatial sensing system for mobile robots using a single speaker-microphone pair, and a comprehensive voice and motion tracking interface that operates on a single frequency.


Yang Bai is a 4th year Ph.D. student at the University of Maryland College Park, supervised by Prof. Nirupam Roy. Her research focuses on minimalist perception, a strategic approach to sensing technology, emphasizing simplicity and efficiency in capturing essential information. She is a recipient of N2Women Young Researcher Fellowship, Future Faculty Fellowship of Clark school, and Graduate Student Award. Her work also received Best Paper Award of MobiSys 2022, SIGMOBILE Research Highlight of 2023 and Best Demo Award of MobiSys 2021.
