Designers of natural user interfaces are faced with several challenges when creating interaction models for controlling applications, including the wide range of possible input actions and the lack of affordances, which they can use to design controls.

We investigated three top-down approaches to designing intuitive interaction mappings for a whole body system implemented with camera vision.
