Wearable Sensors for Human Activity Monitoring: A Review

Abstract

An increase in world population along with a significant aging portion is forcing rapid rises in healthcare costs. The healthcare system is going through a transformation in which continuous monitoring of inhabitants is possible even without hospitalization. The advancement of sensing technologies, embedded systems, wireless communication technologies, nano technologies, and miniaturization makes it possible to develop smart systems to monitor activities of human beings continuously. Wearable sensors detect abnormal and/or unforeseen situations by monitoring physiological parameters along with other symptoms. Therefore, necessary help can be provided in times of dire need. This paper reviews the latest reported systems on activity monitoring of humans based on wearable sensors and issues to be addressed to tackle the challenges.Index Terms-Wearable sensors, smart sensors, sensor networks, wireless sensor networks, body sensor networks, body area networks, activity monitoring, assisted living, smart home, physiological parameters monitoring.1530-437X He is currently a Professor of Sensing Technology with the School of Engineering and Advanced Technology, Massey University, Palmerston North, New Zealand.

Biological-Signal-Based User-Interface System for Virtual-Reality Applications for Healthcare

“…In contrast to the visual and movement data that change according to personal intention, biological-signal information such as user body temperature and HR can provide not only user health information but also bodily responses that change according to environmental changes [22]. Because noninvasively detecting, collecting, and processing various types of body-related data such as electricity, heat, and optical signals produced by the body have recently become possible, medical expenses can be greatly reduced by making possible the prevention and remote detection of health issues [23]. The extraction of noninvasive biological signals has been interlinked with miniaturized sensor technology and led to the development of wearable devices.…”

Activity and Emotion Recognition for Elderly Health Monitoring

“…Automatic recognition of Activities of Daily Living (ADL) in the context in which elderly care is conducted, such as detection of person falling down [3], Detecting gait freezing [4] and more complicated activities [5][6][7][8][9].…”

“…They can be divided into three categories related on the type of data they are based on: i) Motion-sensor-based methods [7,[10][11][12][13], attached or wearable, they utilize on body sensors like the accelerometer and gyroscope, to sense the movements of body parts. ii) Radio-based methods [14,15], the wireless radio types include: ZigBee; which build a small network of sensors on the body.…”

Feature diversity for fall detection and human indoor activities classification using radar systems

“…Irregularities and anomalies in these patterns could inform carers and health professionals on risks related to deteriorating physical and cognitive capabilities. Many different types of sensors and technologies have been suggested for this purpose, namely wearable devices such as accelerometers, inertial sensors, and panic buttons, infrared proximity sensors, magnetic and acoustic sensors, videocameras, RGB-Depth sensors, and radar sensors [3][4][5][6][7]. The interest in radar technologies for indoor monitoring is related to their contactless sensing capabilities, with no need for the users to wear or carry devices or change their habits, and to the insensitivity to light conditions in the environment where the monitored subjects operate.…”
