This paper describes an interactive computerized editor for Benesh Movement Notation that aids in the preparation of dance scores on a medium resolution colour display. Benesh Movement Notation is a two-dimensional system for recording human movement in three dimensions of space which has been successfully used in the preparation of scores for a wide repertoire of dances. The preparation and revision of Benesh scores is a lengthy and error-prone process which interactive editing techniques can greatly facilitate. We describe the current state and future extensions of a prototype editing system in which all user interaction is based on a menu-driven scheme using a graphics tablet. Extensive visual cues including iconic trackers and semantic information are provided at all times. Both user and system initiated dialogues are supported. This system has served as a testbed for a variety of man-machine interaction studies, allowing us to transfer the wealth of experience with interactive text editing to a related task: the preparation of dance scores. The project has given us a better understanding of the issues involved in implementing an effective user-interface.
