Surgical tool positioning is a challenging task requiring 6 DoF precision. This project aims to improve the quasi-static visual elements of the state-of-the-art with a novel widget implementation  considering the Human-centered design approach. The main objective is the surgeon can seek and interact in a quick, pre-attentive way. We compare  our innvoative widget design with the golden standard in a user test, measuring the time, translational and rotational error, and user usability. The innovative 3D spatial user interface leverages Gestalt principles to achieve better visual perception for the user.
