We present a tool to help practitioners to characterize, compare and design gesture guiding systems. The tool can be used to find an example system meeting specific requirements or to start exploring an original research area based on unexplored design options. The motivation for the online tool is the large underlying design space including 35 design axes: the tool therefore helps explore and combine the various design options. Moreover the tool currently includes the description of 46 gesture guiding systems: the tool is thus also a repository of existing gesture guiding systems.
