Some pioneer WiFi signal based human activity recognition systems have been proposed.
Their key limitation lies in the lack of a model that can quantitatively correlate CSI dynamics …

Since human bodies are good reflectors of wireless signals, human activities can be
recognized by monitoring changes in WiFi signals. However, existing WiFi-based human …

Recent research has shown that human motions and positions can be recognized through
WiFi signals. The key intuition is that different motions and positions introduce different …

In this article, we present a work using a smartphone with an off-the-shelf WiFi router for
human activity recognition with various scales. The router serves as a hotspot for …

Nowadays, human behavior recognition research plays a pivotal role in the field of human-
computer interaction. However, comprehensive approaches mainly rely on video camera …

An extensive set of research efforts have explored Channel State Information for human
activity detection. By extracting CSI from a sequence of packets, one can statistically analyze …

Human activity tracking plays a vital role in human–computer interaction. Traditional human
activity recognition (HAR) methods adopt special devices, such as cameras and sensors, to …

Indoor human activity recognition remains a hot topic and receives tremendous research
efforts during the last few decades. However, previous solutions either rely on special …

Prior research has shown the potential of device-free WiFi sensing for human activity
recognition. In this paper, we show for the first time WiFi signals can also be used to …

The joint of WiFi‐based and vision‐based human activity recognition has attracted
increasing attention in the human‐computer interaction, smart home, and security …
