Integrating Eye Tracking and Inertial Sensing for Enhanced Freezing of Gait Detection in Parkinson's Disease. [PDF]
Eur J NeurosciWearable systems using inertial sensors can misclassify voluntary standing as freezing of gait (right). Adding eye‐gaze kinematics to a deep learning model reduces this error (left): standing misclassified as freezing decreases from 59.1% to 13.6%, standing recall more than doubles from 36.4% to 81.8%, and macro‐averaged F1 improves significantly from ...

A Simple and Valid Method to Calculate Wheelchair Frame Rotation Using One Wheel-Mounted IMU
Sensors, 2023 Wheelchair sports have been using Inertial Measurement Units (IMU) to measure mobility metrics during training, testing and competition. Presently, the most suitable solution to calculate wheelchair speed and frame rotation is the 3IMU method as there is

Regression Model-Based Walking Speed Estimation Using Wrist-Worn Inertial Sensor. [PDF]
PLoS ONE, 2016 Walking speed is widely used to study human health status. Wearable inertial measurement units (IMU) are promising tools for the ambulatory measurement of walking speed. Among wearable inertial sensors, the ones worn on the wrist, such as a watch or band,

Predicting Ground Reaction Forces in Sprint Running Using a Shank Mounted Inertial Measurement Unit
Proceedings, 2018 The transition from a stationary crouch on running-blocks to an erect running position is critical to success in sprint running. Three elite sprinters repeated five sprint starts on a 50 m-long instrumented running track each wearing three inertial ...
