Few tools exist to support creative authoring with interactive or generative components. Cochoreo is a sub-module for generating body positions as keyframes that catalyze creative movement, as part of the movement sketching tool idanceForms (idF). Cochoreo catalyzes movement sketching by using parameters from Laban Movement Analysis, an existing movement framework, to generate unique keyframes that are used as seed material for choreographic process. idF is a creativity support tool that engages with choreographers’ creative movement process by design. This paper presents the design of Cochoreo and evaluations from our pilot study with university dance students.
