AI has provided us with the ability to automate tasks, extract information from vast amounts of
data, and synthesize media that is nearly indistinguishable from the real thing. However …

The prevalence of WiFi devices and ubiquitous coverage of WiFi networks provide us the
opportunity to extend WiFi capabilities beyond communication, particularly in sensing the …

Device-free gesture tracking is an enabling HCI mechanism for small wearable devices
because fingers are too big to control the GUI elements on such small screens, and it is also …

We present fingerIO, a novel fine-grained finger tracking solution for around-device
interaction. FingerIO does not require instrumenting the finger with sensors and works even …

Voice biometrics is drawing increasing attention as it is a promising alternative to legacy
passwords for mobile authentication. Recently, a growing body of work shows that voice …

Personal voice assistants (PVAs) are increasingly used as interfaces to digital environments.
Voice commands are used to interact with phones, smart homes, or cars. In the United …

This paper demonstrates the feasibility of a side-channel attack to infer keystrokes on touch
screen leveraging an off-the-shelf smartphone. Although there exist some studies on …

Vibration measurement is a crucial task in industrial systems, where vibration characteristics
reflect the health and indicate anomalies of the objects. Previous approaches either work in …

Voice authentication is drawing increasing attention and becomes an attractive alternative to
passwords for mobile authentication. Recent advances in mobile technology further …

In this study, we present WindTalker, a novel and practical keystroke inference framework
that allows an attacker to infer the sensitive keystrokes on a mobile device through WiFi …
