ErgoExposure - Measurement and illustration of ergonomic exposure

Therefore, we want to try a novel method for this purpose, specifically by using Exposure Variance Analysis (EVA), which has previously been used for analysis of physiological signals (e.g. EMG). With this method we can illustrate both the angular intervals within which the arm has moved, and whether the movement has been static or dynamic.

Benefits 
ErgoExposure contains functions that give ergonomists the opportunity to systematically collect measurement data that describes a person's ergonomic exposure in everyday life. Today, this is usually done through observational studies directly at a workplace. The app assistance the ergonomist by allowing a more objective measure of a person's exposure, while at the same time removing the need for firsthand observations, increasing the freedom of the ergonomist. Instead, the study person can carry out the measurements themselves. This way, the ergonomist can be more efficient in their work, resulting in an increased amount of workplace visits.
