This book aims to capture recent advances and breakthroughs in in-home radar monitoring
of human motions and activities. It addresses three key attributes of radar for in-door human …

Our society will face a notable demographic shift in the near future. According to a United
Nations report, the ratio of the elderly population (aged 60 years or older) to the overall …

Action monitoring in a home environment provides important information for health
monitoring and may serve as input into a smart home environment. Visual analysis using …

A method and system for interacting with an input device is provided. The method includes
initializing a virtual keyboard viewable via an eyewear based video display enabled …

In the past two decades, radar-based human sensing has become a topic of intense
research. Unlike vision-based techniques which require the use of camera, radars are …

A sensing device for a touchless, hand gesture, user interface based on an inexpensive
passive infrared pyroelectric detector array is presented. The 2 x 2 element sensor responds …

Due to the disadvantages of traditional localization & tracking at those aspects of users'
privacy protection, system configuration and maintenance, this paper proposes a new …

This paper presents a low-power digital signal processor for gesture detection using infrared
(IR) sensors. IR compatible detecting algorithms are introduced to reduce power …

Proximity-based motion gesture sensors (MGSs) using IR LEDs have been widely
researched for contactless human-machine interfaces. Conventional MGSs have …

In this paper, we propose an ultra-low-resolution infrared (IR) images based activity
recognition method which is suitable for monitoring in elderly care-house and modern smart …
