In addition to the noise optimization-based control, we propose a reinforcement learning-based method for fast online generation. It models motion control as a Markov decision process with a latent action space and use RL to learn efficient goal-achieving policies. 7/8

The first method employs gradient descent optimization over latent diffusion noise variables to find optimal solutions. This plug-and-play approach supports diverse spatial control tasks, like keyframe body or joint trajectory-based control, as shown in the video results. 6/8

To eliminate implausible motion sequence solutions and enhance generation realism, we propose two methods that leverage the latent space learned by the motion primitive diffusion model to find high-quality motion sequence solutions. 5/8.

While language provides a human-friendly interface for controlling semantics, relying solely on text fails us in precise spatial control. We formulate motion control as a minimization problem:.4/8

DartControl uses an architechture of autoregressive latent diffusion to learn a motion primitive space jointly conditioned on the text prompts and motion history. The trained denoiser and decoder models enable real-time, text-driven motion generation. 3/8

Each frame of the human motion primitives is represented using an overparamterized representation that supports real-time animation and spatial control tasks. 2/8

DartControl decomposes long motion sequences into overlapping motion primitives, which more tracable for generative learning and suitable for online generation. 1/8

Method: .DIMOS formulates synthesizing human motions in 3D scenes as a Markov decision process with latent action spaces, which are learned from motion capture data. The virtual human agents are driven by scene-aware and goal-driven policies to synthesize various behaviors. 3/3

Given a 3D scene, DIMOS enables virtual humans to navigate in the environment and interact with objects in a realistic manner. Furthermore, DIMOS can generate more diverse human motions than previous methods, reflecting the subtle differences in real human behaviors. 2/3.
