RTSIMU: Real-Time Simulation tool for IMU sensors

A software system, called RTSIMU, was developed for analyzing worker movements in the textile industry using Inertial Measurement Units (IMUs). RTSIMU software converts raw positioning data from IMUs into quaternions, which represent orientation relative to the Earth, and further translates them into angular values of movement. To assess relevant angular values and simulate various working movements (such as abduction, flexion, rotation, and elevation of both shoulders), a biomechanical model of the upper body was created using OpenSim to visualize and evaluate these movements in real-time and offers a unique approach for analyzing worker movements, potentially enhancing work safety and productivity.
