Human movement prediction is difficult as humans naturally exhibit complex\nbehaviors that can change drastically from one environment to the next. In\norder to alleviate this issue, we propose a prediction framework that decouples\nshort-term prediction, linked to internal body dynamics, and long-term\nprediction, linked to the environment and task constraints. In this work we\ninvestigate encoding short-term dynamics in a recurrent neural network, while\nwe account for environmental constraints, such as obstacle avoidance, using\ngradient-based trajectory optimization. Experiments on real motion data\ndemonstrate that our framework improves the prediction with respect to\nstate-of-the-art motion prediction methods, as it accounts to beforehand unseen\nenvironmental structures. Moreover we demonstrate on an example, how this\nframework can be used to plan robot trajectories that are optimized to\ncoordinate with a human partner.\n
