+**UniWM** introduce a unified, memory-augmented world model paradigm integrating egocentric visual foresight and planning within a single multimodal autoregressive backbone. Unlike modular frameworks, UniWM explicitly grounds action decisions in visually imagined outcomes, ensuring tight alignment between visualization and planning. A hierarchical memory mechanism further integrates detailed short-term perceptual cues with longer-term trajectory context, enabling stable, coherent reasoning over extended horizons.
+
+You are also welcome to explore our previous work, including [**GOViG**](https://github.com/F1y1113/GoViG), which introduces a new task that we leverage multimodal LLM reasoning to generate navigation instructions directly from egocentric visual observations of the initial and goal states and [**HA-VLN**](https://github.com/F1y1113/HA-VLN/), where we introduce HA-VLN 2.0, a unified benchmark coupling discrete (DE) and continuous (CE) navigation paradigms with explicit social-awareness constraints.
+
+
+### Data
+
+We host the UniWM dataset on Hugging Face: [`fly1113/UniWM_Dataset`](https://huggingface.co/datasets/fly1113/UniWM_Dataset). 
+
+- [`go_stanford`](https://huggingface.co/datasets/fly1113/UniWM_Dataset/resolve/main/go_stanford.tar), [`recon`](https://huggingface.co/datasets/fly1113/UniWM_Dataset/resolve/main/recon.tar), [`sacson`](https://huggingface.co/datasets/fly1113/UniWM_Dataset/resolve/main/sacson.tar), [`scand`](https://huggingface.co/datasets/fly1113/UniWM_Dataset/resolve/main/scand.tar) used for both training and evaluation.
+- [`tartandrive`](https://huggingface.co/datasets/fly1113/UniWM_Dataset/resolve/main/tartandrive.tar) reserved for unseen evaluation only.
+- [`1XHumanoid`](https://huggingface.co/datasets/fly1113/UniWM_Dataset/resolve/main/1XHumanoid.tar) reserved for humanoid navigation.
+
+The directory structure will look like:
+
+```
+data/
+├── go_stanford/
+│   ├── traj_0000/
+│   │   ├── 0.jpg
+│   │   ├── 1.jpg
+│   │   ├── ...
+│   │   ├── n.jpg
+│   │   └── traj_data.pkl
+│   ├── traj_0001/
+│   └── ...
+└── ...
+```
+
+Each `traj_xxxx/` folder contains a sequence of egocentric frames (`0.jpg`, `1.jpg`, ..., `n.jpg`) and a `traj_data.pkl` file storing the per-step metadata (e.g., actions, poses) for that trajectory. The other splits follow the same layout.
