SoundWave: using the doppler effect to sense gestures
TLDR
We present SoundWave, a sound-based gesture sensing approach that leverages the speaker and microphone already embedded in most commodity devices to sense in-air gestures around the device. Expand

FingerIO: Using Active Sonar for Fine-Grained Finger Tracking
TLDR
We present fingerIO, a novel fine-grained finger tracking system that does not require instrumenting the finger with sensors and works even with occlusions between the finger and the device. Expand

Demonstrating the feasibility of using forearm electromyography for muscle-computer interfaces
TLDR
We explore the feasibility of muscle-computer interfaces (muCIs): an interaction methodology that directly senses and decodes human muscular activity rather than relying on physical device actuation or user actions that are externally visible or audible. Expand
