To counteract this, an interaction-based arm assistance system has been developed to physically unload the surgeon's upper extremities during laparoscopic procedures. This is achieved by actively supporting the forearms with a supporting force following the natural movements without restrictions. The release of the forearms from the system is achieved by a rapid vertical movement of the arms. The assistance system is controlled exclusively by a form fit and frictional connection of the forearms. Within the scope of this research project, the interface parameter form of the forearm rest is therefore investigated on the basis of five anthropomorphic shape variants of the form with dynamic and static tasks. The study shows an influence of percentile-adapted forms on the usability of forearm supports at an arm assistance system. The form percentile results in no correlation to the objective parameters examined in this study: the number of errors or errors per second. There are differences in the perception of comfort by different subject percentiles. The post-study survey shows that subjects prefer form percentiles close to their own forearm percentile and, on the other hand, find forms that are too large or small uncomfortable. Design recommendations and dimensional recommendations for the design of open anthropomorphic forms for the interaction with arm assistance systems are derived from the results. %@ 978-3-031-32198-6
