CLEAR: Online Speech Content Leakage Estimation through Cross-ASR Disagreement
Bhawana Chhaglani, Tanvi Kandepuneni, Jeremy Gummeson +1
Signal-level speech privacy mechanisms suppress linguistic content while preserving acoustic information needed by downstream sensing applications. However, their privacy settings…
FeatureSense: Protecting Speaker Attributes in Always-On Audio Sensing System
Bhawana Chhaglani, Sarmistha Sarna Gomasta, Yuvraj Agarwal +2
Audio is a rich sensing modality that is useful for a variety of human activity recognition tasks. However, the ubiquitous nature of smartphones and smart speakers with always-on m…
Sonicmesh: Enhancing 3D Human Mesh Reconstruction in Vision-Impaired Environments With Acoustic Signals
Xiaoxuan Liang, Wuyang Zhang, Hong Zhou +7
3D human mesh reconstruction (HMR) from RGB images often degrades under poor illumination, occlusion, and non-line-of-sight conditions. Acoustic sensing provides complementary spat…
Towards Privacy-Preserving Audio Classification Systems
Bhawana Chhaglani, Jeremy Gummeson, Prashant Shenoy
Audio signals can reveal intimate details about a person's life, including their conversations, health status, emotions, location, and personal preferences. Unauthorized access or…
Jointly Managing Electrical and Thermal Energy in Solar- and Battery-powered Computer Systems
Noman Bashir, Yasra Chandio, David Irwin +3
Environmentally-powered computer systems operate on renewable energy harvested from their environment, such as solar or wind, and stored in batteries. While harvesting environmenta…
mmWall: A Transflective Metamaterial Surface for mmWave Networks
Kun Woo Cho, Mohammad H. Mazaheri, Jeremy Gummeson +2
Mobile operators are poised to leverage millimeter wave technology as 5G evolves, but despite efforts to bolster their reliability indoors and outdoors, mmWave links remain vulnera…
FlowSense: Monitoring Airflow in Building Ventilation Systems Using Audio Sensing
Bhawana Chhaglani, Camellia Zakaria, Adam Lechowicz +2
Proper indoor ventilation through buildings' heating, ventilation, and air conditioning (HVAC) systems has become an increasing public health concern that significantly impacts ind…
mmWall: A Reconfigurable Metamaterial Surface for mmWave Networks
Kun Woo Cho, Mohammad Hossein Mazaheri, Jeremy Gummeson +2
To support faster and more efficient networks, mobile operators and service providers are bringing 5G millimeter wave (mmWave) networks indoors. However, due to their high directio…
Pushing the Physical Limits of IoT Devices with Programmable Metasurfaces
Lili Chen, Wenjun Hu, Kyle Jamieson +3
Small, low-cost IoT devices are typically equipped with only a single, low-quality antenna, significantly limiting communication range and link quality. In particular, these antenn…
Empirical Characterization of Mobility of Multi-Device Internet Users
Amee Trivedi, Jeremy Gummeson, Prashant Shenoy
Understanding the mobility of humans and their devices is a fundamental problem in mobile computing. While there has been much work on empirical analysis of human mobility using mo…
