Physical activity classification using the GENEA wrist-worn accelerometer.
INTRODUCTION Most accelerometer-based activity monitors are worn on the waist or lower back for assessment of habitual physical activity. Output is in arbitrary counts that can be classified by activity intensity according to published thresholds. The purpose of this study was to develop methods to classify physical activities into walking, running, household, or sedentary activities based on r...
متن کاملValidity and Comparability of a Wrist-Worn Accelerometer in Children.
BACKGROUND: Wrist-worn accelerometers may provide an alternative to hip-worn monitors for assessing physical activity as they are easier to wear and may thus facilitate long-term recordings. The present study aimed at a) assessing the validity of the Actiwatch (wrist-worn) for estimating energy expenditure b) determine cut-off values for light, moderate and vigorous activities, c) studying the ...
متن کاملActivities of Daily Life (ADL) Recognition using Wrist-worn Accelerometer
Activity recognition has become the necessity of smart homes, future factories, and surveillance. Activities independent of body posture predominantly exhibiting gestures involving both arm and the wrist motion supports the use of the wearable sensors for data acquisition. This paper uses an algorithm based prediction method to recognize the Activities of Daily Life (ADL) involving activities l...
متن کاملTechnical variability of the Vivago® wrist-worn accelerometer.
The aim was to assess the technical variability of a new wrist-worn accelerometer under controlled conditions with a shaker device and during normal daily physical activities (PAs). In the first experiment, 10 wrist-worn accelerometers (Vivago(®) Wellness, Paris, France) were attached to the shaker device. Variability was tested at five shaking frequencies (1.1, 2.1, 3.1, 4.1, and 10 Hz) for 10...
متن کاملComparison of activity levels measured by a wrist worn accelerometer and direct observation in young children
Introduction: Motion sensors are mechanical and electronic devices, which detect the body movement and provide an estimate of physical activity in children and adults. However, they need to be validated against criterion methods such as direct observation. The purpose of this study was to validate a wrist worn accelerometer to quantify the physical activity of children, by comparison to direct ...
