+
+**SpatiaLab** is a benchmark for evaluating **spatial reasoning** in vision–language models (VLMs) under **real-world, in-the-wild** visual conditions.  
+It includes **1,400 visual question–answer pairs** across **6 core spatial categories** and **30 subcategories**, supporting both **multiple-choice (MCQ)** and **open-ended** evaluation formats.  
+SpatiaLab exposes substantial gaps between state-of-the-art VLMs and human performance.
+
+
+---
+
+
+
+## Overview
+
+**Spatial reasoning** is fundamental to human intelligence and real-world embodied AI.  
+SpatiaLab provides a comprehensive evaluation suite (1,400 QA pairs) across six core spatial categories:
+
+- Relative Positioning
+- Depth & Occlusion
+- Orientation
+- Size & Scale
+- Spatial Navigation
+- 3D Geometry
+
+It is designed to test VLMs in **realistic, unconstrained scenes** and highlights large performance gaps between models and humans.
+
+---
+
+## Benchmark Structure and Categorization
+
+SpatiaLab comprises **1,400** validated QA items organized into **6 main categories** and **30 subcategories** (**5** subcategories each).
+
+| Category | Example sub-tasks (5 each) |
+|---|---|
+| **Relative Positioning** | Left/Right, Above/Below, Between, Adjacency, Corner/Angle |
+| **Depth & Occlusion** | Partial occlusion, Complete occlusion, Layer order, Reflection/visibility, Hidden feature |
+| **Orientation** | Rotation angle, Facing, Tilt, Tool handedness, Mirror |
+| **Size & Scale** | Relative size, Scale ratio, Big/Small, Proportion, Size consistency |
+| **Spatial Navigation** | Path existence, Obstacle avoidance, Turn sequence, Viewpoint visibility, Accessibility |
+| **3D Geometry** | 3D containment, Intersection, Volume ordering, Pose matching, Stability |
+
+
+---
+
+## Key Takeaways
+
+- **Large human–model gap.**  
+  MCQ: top models ~55% vs humans 87.6%.  
+  Open-ended: best ~41% vs humans ~65%.
+
+- **Open-ended is much harder.**  
+  Average MCQ → Open-ended drop is substantial across models.
+
+- **Scale alone is not sufficient.**  
+  Some large models remain weak; small models often cluster near the bottom.
+
+- **Spatial “specialists” don’t necessarily generalize.**  
+  Specialized spatial models can underperform broadly, especially in open-ended settings.
+
+---
+
+## Error Analysis Summary
+
+Common failure modes observed across models:
+- Spatial mislocalization in cluttered scenes (wrong referents)
+- Perspective/scale mistakes (over-reliance on size priors)
+- Occlusion and ordering failures (thin/partially hidden structures)
+- Fluent but visually ungrounded open-ended answers
+- Multi-cue integration failures (depth + size + ordering)
+- Poor confidence calibration in open-ended generation
+
+---
+
+## Methods
+
+- **Image sources:** web crawling, targeted retrieval, manual capture
+- **Annotation:** trained annotators + 3-stage review/QC
+- **Evaluation:**
+  - MCQ: option selection + exact match
+  - Open-ended: free-form generation + judge scoring (validated against human agreement)
+- **Metrics:** accuracy + agreement measures (e.g., Cohen’s / Fleiss’ kappa reported in paper)
+
+### Performance Improvement Approaches (Explored)
+- Inherent reasoning-enabled models
+- Chain-of-Thought (CoT) prompting
+- CoT + self-reflection
+- Supervised fine-tuning (SFT)
+- Multi-agent system (SpatioXolver)
