With the development of the Internet of Things (IoT), many kinds of wireless signals (eg, Wi-
Fi, LoRa, RFID) are filling our living and working spaces nowadays. Beyond communication …

Wireless networks have been widely deployed with a high demand for wireless data traffic.
The ubiquitous availability of wireless signals brings new opportunities for non-intrusive …

We propose SignFi to recognize sign language gestures using WiFi. SignFi uses Channel
State Information (CSI) measured by WiFi packets as the input and a Convolutional Neural …

Wi-Fi localization and tracking face accuracy limitations dictated by antenna count (for angle-
of-arrival methods) and frequency bandwidth (for time-of-arrival methods). This paper …

Past decades have witnessed the extension of the Wi-Fi signals as a useful tool sensing
human activities. One common assumption behind it is that there is a one-to-one mapping …

With the flourish of the smart devices and their applications, controlling devices using
gestures has attracted increasing attention for ubiquitous sensing and interaction. Recent …

Enabling touch gesture sensing on all surfaces of the mobile device, not limited to the
touchscreen area, leads to new user interaction experiences. In this paper, we propose …

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 …

WiFi-based gesture recognition emerges in recent years and attracts extensive attention
from researchers. Recognizing gestures via WiFi signal is feasible because a human …

Respiratory diseases have been a significant public health challenge. Efficient disease
evaluation and monitoring call for daily spirometry tests, as an effective way of pulmonary …
