Analysis of ergonomic and unergonomic human lifting behaviors by using Inertial Measurement Units

Accurate Position Tracking Using Inertial Measurement Units

Indoor Positioning Using Inertial Measurement Units

With the increase in the number of smart phone users worldwide there comes a high demand for smart phone based location systems. Within the project “Indoor positioning using inertial measurement units” an android application has been developed wherein the position of the smart phone user with respect to the floor environment is determined. This has been achieved using the smart phone sensors st...

Improving Accuracy of Inertial Measurement Units using Support Vector Regression

Inertial measurement unit (IMU) is a sensor that measures acceleration and angular velocity rate. It has become increasingly popular due to its small size and low cost comparing to typical marker-based motion capture system. Nonetheless, IMUs face considerable challenges, in particular noticeable inaccuracy from accumulated integration errors. In this project, we attempted to improve accuracy o...

Postural Stability Analysis with Inertial Measurement Units in Alzheimer's Disease

BACKGROUND The cause of frequent falls in patients with Alzheimer's disease (AD) is still not well understood. Nevertheless, balance control and sensory organization are known to be critical for moving safely and adapting to the environment. METHODS We evaluated postural stability in 20 AD patients (11 fallers and 9 nonfallers) and 16 healthy controls with an inertial measurement unit (triaxi...

Android Platform for Realtime Gait Tracking Using Inertial Measurement Units

One of the most important movements performed by the humans is gait. Biomechanical Gait analysis is usually by optical capture systems. However, such systems are expensive and sensitive to light and obstacles. In order to reduce those costs a system based on Inertial Measurements Units (IMU) is proposed. IMU are a good option to make movement analisys indoor with a low post-processing data, all...
