Researchers have developed SparseCtrl-HOI, a new framework for generating videos of human-object interactions, which significantly reduces the need for dense temporal guidance. This method utilizes only a few keyframes to control the interaction process, lowering annotation costs and increasing motion diversity. The framework incorporates a Time-Controlled Rotary Positional Embedding (TiRoPE) for temporal anchoring and a Motion Prior Injection Module that leverages Multimodal Large Language Models (MLLMs) to generate plausible transitions between keyframes. Additionally, a new dataset called SparseHOI-5K has been created to support this sparse temporal control approach, demonstrating superior results in synthesizing videos for applications like live-streaming e-commerce.
