User Interfaces (UIs) are essential tools in the establishment of environments where users can use computers or electronic gadgets more conveniently. They may also prove useful for controlling robots in the difficult imitation learning process that takes place during the production of Human Robot Interaction (HRI) contents. To this end, we propose the “imitation learning-based behavior generator” interface to aid in the HRI contents’ production process. The proposed interface includes a UI that provides an easier robot control when a user conducts imitation learning activities.
