The Dynamicus tools have been specially developed for the use of motion capture systems in motion analysis. They support the acquisition of the data necessary for the analysis and use the method base of Dynamicus and the alaska/SimulationEngine under a special user interface that focuses on conducting tracking experiments and evaluating the tracked motion. From the tracking experiment to the evaluation result in pdf format, only a few steps are often necessary. At the same time, the tools offer a clear visualization of experiments and simulation results, providing maximum security and transparency with regard to the evaluation. In addition to freely accessible ergonomics assessment procedures, the Dynamicus Tools concept can also be used to implement assessment procedures that include special evaluation criteria for workstations or products of a company.
Dynamicus Tools include:
Dynamicus/Recorder processes real-time sensor signals from motion capture systems. In particular, ART's system is supported as an optical and hybrid optical-accelerometric system. With the ART system, real-time recordings can be carried out in very good quality even under difficult visibility conditions.
The recorder has a session wizard that supports all steps of a tracking experiment from sensor configuration to calibration and recording. The subject's movements can be used to improve the accuracy of anthropometric data and calibration information.
The integrated session trial concept supports the efficient execution of a large number of experiments.
After completion of the experiment, an editing functionality allows further processing of the recorded data. Values of the tracking sensors, data of the human model belonging to the test person and calibration information are stored in a database. Experiments stored in the Motion Capture database can be simulated and evaluated by any Dynamicus/AssessmentStudio plug-in without further manual editing.
The Dynamicus/AssessmentStudio provides the framework for the implementation of various assessment procedures. It contains the methods required for motion simulation and provides the framework for a user interface that combines 3D animation and the evaluation variables displayed as a diagram. Due to the implemented plug-in concept, the AssessmentStudio can integrate completely different evaluation methods into the framework of the AssessmentStudio, which require special evaluation variables, evaluation algorithms, displays and interactive inputs.
With the Dynamicus/EAWS plug-in, a tracked motion can be evaluated in terms of ergonomics using the EAWS (Ergonomic Assessment Worksheet) procedure. The EAWS procedure has been specially developed for recurring tasks, such as assembly, and evaluates the risk of damage to an executed working operation with a point value.
The process is the result of research in the field of occupational science (e. g. Schaub, K. G.Brother, R: The European Assembly Worksheet. Theoretical Issues in Ergonomics Science. Volume 14, Number 6,2013, pp. 616-639) and is documented in the form of a standard that is continuously being developed.
The EAWS procedure represents a combined posture/force assessment, whereby the risk of damage is integrated over a certain working operation. The posture evaluation can be generated with Dynamicus largely automatically. The external forces resulting from working operations or the handling of loads can be interactively added via the GUI resources of Dynamicus/EAWS. The result of an EAWS evaluation is documented in the form of standardized forms. Dynamicus/EAWS creates these forms in the form of a pdf file.
The following video shows how to use the Dynamicus/EAWS software.
The plug-in Dynamicus/RULA contains an implementation of the RULA procedure (Lynn McAtamney, Nigel Corlett: RULA - A survey method for investigation of work-related upper limb disorders. Applied Ergonomics 1993,24 (2), 91-99). The procedure is used to assess the risk of damage to the upper extremities from working positions. In contrast to the EAWS method, the procedure evaluates each posture separately. The forces acting on the patient's body as well as the posture taken are also evaluated. The posture evaluation is calculated by Dynamicus. If necessary, the forces acting can be entered interactively. The illustration shows the visualization of the individual components of the RULA procedure as well as the possibility of manually correcting the assignment of motion variables to the loading classes of the procedure.
The following video shows the application of the RULA procedure to evaluate a machine operation.
