Human Action Recognition (HAR) aims to understand human behavior and assign a label to
each action. It has a wide range of applications, and therefore has been attracting increasing …

With the high demand for wireless data traffic, WiFi networks have experienced very rapid
growth, because they provide high throughput and are easy to deploy. Recently, Channel …

Driven by a wide range of real-world applications, significant efforts have recently been
made to explore device-free human activity recognition techniques that utilize the …

The past few years have witnessed the great potential of exploiting channel state information
retrieved from commodity WiFi devices for respiration monitoring. However, existing …

With the advancement of wireless technologies and sensing methodologies, many studies
have shown the success of re-using wireless signals (eg, WiFi) to sense human activities …

Human activity recognition can benefit various applications including healthcare services
and context awareness. Since human actions will influence WiFi signals, which can be …

This paper presents Widar2. 0, the first WiFi-based system that enables passive human
localization and tracking using a single link on commodity off-the-shelf devices. Previous …

In this article, we present a survey of recent advances in passive human behavior
recognition in indoor areas using the channel state information (CSI) of commercial WiFi …

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 …

In this paper, we propose WifiU, which uses commercial WiFi devices to capture fine-grained
gait patterns to recognize humans. The intuition is that due to the differences in gaits of …
