An automatic in-home fall detection system using Doppler radar signatures

Published On: 07-21-2016

One in three elders over the age of 65 falls each year in the United States. This paper describes a non-invasive fall detection system based on a Doppler radar sensor. The developed system has been tested in two environments:...

Using embedded sensors in independent living to predict gait changes and falls

Published On: 07-26-2016

This study explored using Big Data, totaling 66 terabytes over 10 years, captured from sensor systems installed in independent living apartments to predict falls from pre-fall changes in residents’ Kinect-recorded gait parameters. Over a period of 3 to 48...

Monitoring the relative blood pressure using a hydraulic bed sensor system

Published On: 07-13-2018

We propose a non-wearable hydraulic bed sensor system that is placed underneath the mattress to estimate the relative systolic blood pressure of a subject, which only differs from the actual blood pressure by a scaling and an offset factor....

Assessment of fall characteristics from depth sensor videos

Published On: 07-01-2017

Falls are a major source of death and disability in older adults; little data, however, are available about the etiology of falls in community-dwelling older adults. Sensor systems installed in independent and assisted living residences of 105 older adults...

Older adults’ perceptions and preferences of a fall risk assessment system: Exploring stages of acceptance model

Published On: 07-01-2017

Aging in place is a preferred and cost-effective living option for older adults. Research indicates that technology can assist with this goal. Information on consumer preferences will help in technology development to assist older adults to age in place....

Exploratory analysis of older adults’ sedentary behavior in the primary living area using Kinect depth data

Published On: 02-22-2017

We describe case studies of clinically significant changes in sedentary behavior of older adults captured with a novel computer vision algorithm for depth data. An unobtrusive Microsoft Kinect sensor continuously recorded older adults’ activity in the primary living spaces...

Estimation of human walking speed by Doppler radar for elderly care

Published On: 02-22-2017

This paper presents a human walking speed estimation algorithm using a Doppler radar system for in-home passive gait assessment of elderly adults. The Fast Fourier Transform (FFT) has been a common approach to obtain the gait speed estimation. The...

Radar placement for fall detection: signature and performance

Published On: 01-17-2018

Two popular mounting positions of Doppler radar for human fall detection are in the ceiling center and at the torso level. This paper examines the fall signatures observed by a Doppler radar at the two positions and evaluates their...
