to export the data in text format. Before starting the measurement, the frame rate, called the measurement rate, is set, and the number of frames is directly proportional to the measurement rate. Figure 3 shows the virtual environment in Unity.

Source: Authors, 2021 For the evaluation of the measurements, a tool working on the MS Excel platform was created and supplemented with the required functionality using Visual Basic for Application (VBA) code. This tool allows to process a large amount of data according to predefined parameters and evaluate them at the same time. The output, as can be seen bellow, is a tabular and graphical representation of the total percentage of critical body positions. This gives an initial indication of whether the workplace is ergonomically suitable or whether optimization is needed. Using a tool for evaluating large volumes of data, the results are compared with the limits set by Czech legislation or with the company’s internal standards. The partial output is the number of frames in acceptable, conditionally acceptable and unacceptable positions. The next step is to create a graphical visualisation of the percentage of positions relative to the total number of frames for the selected body parts. Figure 4 illustrates the auxiliary tool for evaluating the positions according to the legislation.
