Smart home-based Prevention Strategies
Validated clinical tool, highlighting importance of mobility and unsteady gait in fall risk
"...the unobtrusive [LiDAR] gait measurement system allows for contactless, highly accurate long- and short-term assessments of gait in home-like environments."
LiDAR & Gait
"The incidence of trip-related falls in healthy older adults is determined primarily by the frequency of tripping..."
Trips & Falls
"Using recorded videos of natural gait of people with dementia, we showed...human pose estimation data are associated with both clinical gait measures and with future observed falls."
Dementia & Falls
"...those who wore the fall detector appropriately reported that they felt more confident and independent, and considered that the detector improved their safety.
One of the conclusions of the study was that the fear of falling is likely to be substantially affected by user perception of the reliability and accuracy of the fall detector."
