MobileDreamer: Generative Sketch World Model for GUI Agent

Understand

Mobile GUI agents have shown strong potential in real-world automation and practical applications.

• However, most existing agents remain reactive, making decisions mainly from current screen, which limits their performance on long-horizon tasks.
• Building a world model from repeated interactions enables forecasting action outcomes and supports better decision making for mobile GUI agents.
• This is challenging because the model must predict post-action states with spatial awareness while remaining efficient enough for practical deployment.
