Linguistic Summarization of Sensor Data for Early Illness Recognition in Eldercare

Extracting information from the sensors installed in the homes of elderly pose a unique set of challenges. Add to it the short amount of time the clinicians and nurses have to analyze this data, and the problem becomes more complicated. The ongoing work in this project focuses on development of algorithms to glean information from in-home sensor data and then presenting it in the form of textual summaries using Natural Language Generation techniques.

Bed Sensor Development for In-Home Cardiac and Respiration Monitoring

In the United States, 37% of the population is affected by cardiovascular related diseases. In order to avoid fatal consequences, in-home monitoring systems have been under development for the purpose of detecting early signs of cardiovascular abnormalities. Monitoring the heart rate and other cardiac parameters during sleep can provide critical information about the health of a subject.

Physical Therapist Functional Assessment Tool

We are developing an application to automate data collection for the physical function assessments that are normally measured manually by physical therapists or nurses. The assessment tool will be used every 6 months to assess older adults’ functional movement and range of motion as part of the Health Kiosk project.

US Ignite: EAGER: GENI-Enabled In-Home, Personalized Health Monitoring and Coaching

We have tested our monitoring and health alert system in TigerPlace, an aging in place facility near the University of Missouri campus in Columbia, MO and, more recently, in assisted living in Cedar Falls, IA. The proposed project will build on this work with an innovative, interactive healthcare service. The monitoring system with health alerts will be introduced into independent housing in Kansas City. A new interactive exercise coaching interface will connect a remote physical therapist to senior clients in the home. GENI-enabled networking will be incorporated to support interactive monitoring and coaching that operates in real-time.

Measuring the Alignment of Piano Students for Injury Prevention

This project is a collaboration between three different disciplines: Music, Engineering and Health Science. The long-term goal is to develop strategies for injury-prevention in undergraduate piano students. Common causes of injury among young pianists are: skeletal misalignment, excessive muscular tension and repetitive stress injury.

Intelligent Sensor System for Early Illness Alerts in Senior Housing

In this randomized controlled study, we are investigating and refining health alerts produced by environmentally-embedded in-home sensor networks designed to detect early signs of health change and functional decline in older adults, the keys to successful intervention.

EAGER: An In-Home Health Alert System with Remote Care Coordination

In this project, we test the concept in senior housing in Cedar Falls, Iowa, using in-home sensors and remote video conferencing for the nurse care coordination. Fiber networking in Columbia and Cedar Falls will provide the bandwidth and latency essential for this approach. Previous system development is utilized and a new hydraulic bed sensor has been integrated. The sensor configuration also includes the team’s previous work with the Kinect depth images for extracting gait parameters of residents in the home.

SHB: Computational Algorithms for Predictive Health Assessment

The main goal of this work was to develop algorithms for early illness recognition in elderly. Early illness recognition (EIR) is important, as research has shown that results in better medical outcomes and a reduction in health care cost. We developed methodologies (see Figure 1) that link sensor data to the medical (nursing) records for monitoring the residents of TigerPlace, an aging in place community from Columbia, Missouri.

HCC: Human-Driven Spatial Language for Human-Robot Interaction

Human subject experiments will be conducted with college students and elderly participants to explore spatial descriptions in a fetch task; results will drive the development of robot algorithms, which will be evaluated using a similar set of assessment experiments in virtual and physical environments.

Technology to Automatically Detect Falls and Assess Fall Risk in Senior Housing

Building on our current work, we propose to validate and deploy an innovative technological approach that automatically detects when falls have occurred or when the risk of falls is increasing. Subjects will not have to press buttons, pull cords or wear any devices. This new “passive” approach using sensors in the home could revolutionize detecting and preventing falls as well as measuring fall risk.

Active Heterogeneous Sensing for Fall Detection and Fall Risk Assessment

We leverage ongoing research at a unique local eldercare facility (TigerPlace) to study active sensing and fusion using vision and acoustic sensors for the continuous assessment of a resident’s risk of falling as well as the reliable detection of falls in the home environment. The project investigates the interplay between fall detection and fall risk assessment.

Technology to Automatically Detect Early Signs of Illness in Senior Housing

Early illness detection and recognition of small changes in health conditions are essential for early interventions when treatment is the most effective and when prevention of dramatic changes are still possible. We propose to develop a prospective innovative technological approach to early illness detection and chronic disease management using inexpensive sensors embedded in the environment.

HCC: Elder-Centered Recognition Technology for the Assessment of Physical Function

Researchers at the University of Missouri-Columbia and the University of Washington have established a multidisciplinary team comprised of researchers in computer science and engineering, nursing, and medical informatics dedicated to developing and evaluating technology to keep older adults functioning at higher levels and living independently. We have leveraged ongoing research at a unique local eldercare facility (TigerPlace) to study vision-based recognition methods for multi-person environments designed to capture continuous and automated assessments of older adults’ physical function.

A Smart Carpet: Technology for Persons with Alzheimer’s Disease

We propose a carpet with pressure sensors distributed throughout the floor with an average of 10 sensors per square foot sheet; these will be incorporated onto flooring material such as carpeting, flexible tiles or linoleum. We will be able to “see” the person’s footsteps, assess their gait, and identify their location.

Technology to Enhance Aging in Place at TigerPlace

The dream of older Americans is to remain as active and independent as possible for as long as possible. They want to age in place, not in institutions like nursing homes. Recently, enabling technology in the form of low cost sensors, computers, and communications systems has become available, which with supportive health care services makes the dream of aging in place a reality.

Technology Interventions for Elders with Mobility and Cognitive Impairments

Americans are living longer and more fulfilled lives, and they desire to live as independently as possible. But independent lifestyles come with risks. To address these issues, researchers are developing “smart home” technologies to help older adults remain independent at home while controlling costs. Smart homes enhance residents’ safety and monitor health conditions using sensors and other devices. Such technology can help keep older adults independent while controlling costs.
