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 …

Current LoRa networks including those following the LoRaWAN specification use the
primitive ALOHA mechanism for media access control due to LoRa's lack of carrier sense …

Gesture recognition is the central enabler of human-computer interaction (HCI). In addition
to the semantic information contained in gestures, gesture-based user identification can …

Technology solutions must effectively balance economic growth, social equity, and
environmental integrity to achieve a sustainable society. Notably, although the Internet of …

Backscatter communication (BC) has been introduced as a cutting-edge technology due to
low cost and ultra-low-power consumption. However, its openness and broadcast nature …

Face authentication (FA) schemes are universally adopted. However, current FA systems
are mainly camera-based and hence susceptible to face occlusion (eg, facial masks) and …

User identified gesture recognition is a fundamental step towards ubiquitous device-free
sensing. We propose WiHF, which first simultaneously enables cross-domain gesture …

In recent years, human pose tracking has become an important topic in computer vision
(CV). To improve the privacy of human pose tracking, there is considerable interest in …

To improve driving safety and avoid accidents caused by driving fatigue, drowsiness
detection aims to alarm the driver before he/she falls asleep. Since breathing rate is a key …

Person identification plays a critical role in a large range of applications. Recently, RF based
person identification becomes a hot research topic due to the contact-free nature of RF …
