The emanations of electronic and mechanical devices have raised serious privacy concerns.
It proves possible for an attacker to recover the keystrokes by acoustic signal emanations …

We present HiLight, a new form of real-time screen-camera communication without showing
any coded images (eg, barcodes) for off-the-shelf smart devices. HiLight encodes data into …

Voice assistants (VAs) are becoming highly popular recently as a general means of
interacting with the Internet of Things. However, the use of always-on microphones on VAs …

This paper explores the possibility of extending the input and interactions beyond the small
screen of the mobile device onto ad hoc adjacent surfaces, eg, a wooden tabletop with …

Low-Power Wide Area Networks, such as LoRaWAN, are rapidly gaining popularity in the
field of wireless sensing and actuation. While LoRaWAN is heavily studied in applications …

Modern acoustic wearables with microphone arrays are promising to offer rich experience
(eg, 360° sound and acoustic imaging) to consumers. Realtime multi-track audio streaming …

Interacting with explosively growing mobile devices is becoming imperative. This paper
presents SoundWrite, a mobile acoustic sensing system that enables text input into …

The enabling Internet-of-Things technology has inspired many innovative sensing
mechanisms by repurposing the onboard sensors. Leveraging the built-in acoustic sensors …

Edge computing applications use the computational, sensor, and networking resources of
nearby mobile and stationary computing devices. Because dissimilar devices can provide …

We present a novel underwater system that can perform acoustic ranging between
commodity smartphones. To achieve this, we design a real-time underwater ranging …
