+# SAT_perspective Dataset
+
+## Paper
+
+**SAT: Dynamic Spatial Aptitude Training for Multimodal Language Models**
+
+This dataset is part of the SAT (Spatial Aptitude Training) project, which introduces a dynamic benchmark for evaluating and improving spatial reasoning capabilities in multimodal language models.
+
+- **Project Page**: [https://arijitray.com/SAT/](https://arijitray.com/SAT/)
+- **Paper**: [arXiv:2412.07755](https://arxiv.org/abs/2412.07755)
+
+## Dataset Description
+
+The SAT_perspective dataset contains 6,527 spatial reasoning questions that test perspective-taking abilities. Each question presents a scene and asks about spatial relationships from a new viewpoint, requiring models to reason about how objects would appear from different camera positions.
+
+## Loading the Dataset
+
+```python
+from datasets import load_dataset
+
+# Load the dataset
+dataset = load_dataset("array/SAT_perspective", split="val")
+
+# Access a sample
+sample = dataset[0]
+print(sample["question"])
+print(sample["choices"])
+```
+
+## Dataset Structure
+
+Each example in the dataset contains the following fields:
+
+- **`images`**: List of input images showing the original scene (PIL Image objects)
+- **`question`**: Text question asking about spatial relationships from a new perspective
+- **`choices`**: List of possible answers (typically 2 options)
+- **`answer_idx`**: Index of the correct answer in the choices list (integer)
+- **`datatype`**: Type of spatial reasoning task (value: "perspective")
+- **`house_ind`**: House/scene identifier (integer)
+- **`cam_position`**: Camera position coordinates as 3D float arrays
+- **`cam_rotation`**: Camera rotation values as float arrays
+- **`image_reason`**: Rendered image from the new perspective that the question is asking about. This provides the ground truth visualization showing what the scene looks like from the target viewpoint.
+
+### Example
+
+```python
+{
+    "images": [<PIL.Image.Image>],  # Original view
+    "question": "If I go to the 'X' marked point in the image and turned left by 90 degrees, will the Chair get closer or further away?",
+    "choices": ["Closer", "Further"],
+    "answer_idx": 0,
+    "datatype": "perspective",
+    "house_ind": 0,
+    "cam_position": [[2.75, 0.9009997844696045, 6.25], [3.75, 0.9009997844696045, 6.75]],
+    "cam_rotation": [96.0, 6.0],
+    "image_reason": [<PIL.Image.Image>]  # View from new perspective
+}
+```
