Leveraging directional antenna capabilities for fine-grained gesture recognition
TL;DR: The proposed recognition scheme leverages directional antenna and short-range wireless propagation properties to recognize a vocabulary of action-oriented gestures from the American Sign Language and can correctly identify and classify up to 25 fine-grain gestures.
Proceedings ArticleDOI
DFT-based hybrid antenna selection schemes for spatially correlated MIMO channels
TL;DR: This work proposes to embed DFT operations in the RF chains to reduce the severe performance degradation of the traditional antenna selection scheme in correlated channels, and shows a significant advantage both for diversity schemes and for the capacity of spatial multiplexing.
Proceedings ArticleDOI
Acoustic Eavesdropping through Wireless Vibrometry
TL;DR: A new acoustic eavesdropping attack that can subvert such protectors using radio devices by inspecting the subtle disturbance it causes to the radio signals generated by an adversary or by its co-located WiFi transmitter is explored.
Proceedings ArticleDOI
Enabling High-Precision Visible Light Localization in Today's Buildings
Shilin Zhu,Xinyu Zhang +1 more
TL;DR: This paper designs iLAMP to enable reliable, high-precision VLP using conventional LEDs and fluorescent lamps inside today's buildings, and develops a geometrical model which combines the camera image with gyroscope/accelerometer output, to estimate a smartphone's 3D location and heading direction relative to each lamp landmark.
Proceedings ArticleDOI
Extending Mobile Interaction Through Near-Field Visible Light Sensing
TL;DR: This paper proposes Okuli, a compact, low-cost system that can augment a mobile device and extend its interaction workspace to any nearby surface area, and uses a low-power LED and two light sensors to locate user's finger within the workspace.
