+# CAGUI: **C**hinese **A**ndroid **GUI** Benchmark  
+A real-world Chinese Android GUI benchmark designed to evaluate **GUI agent models** on two complementary capabilities:
+
+* **Grounding** – understanding individual GUI components and linking them to semantics.
+* **Agent** – planning and executing multi-step actions to complete user goals on Chinese Android apps.
+
+---
+
+## 🌟 Key Features
+| Aspect | Grounding | Agent |
+|--------|-----------|-------|
+| **Objective** | Map bounding boxes ➜ function / OCR text | Follow natural-language instructions to operate an app |
+| **Data** | 2 × JSONL files (`cap.jsonl`, `ocr.jsonl`) + screenshots | Per-episode JSON + step-level screenshots |
+| **Actions** | _n/a_ | Tap, long-tap, text-input, scroll, etc. (`result_action_type`) |

+## 📑 Data Format
+
+### 1. Agent episodes (`CAGUI_agent/domestic/<episode_id>/<episode_id>.json`)
+Each file is a **list of steps**:
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `episode_id` | str | Unique id |
+| `episode_length` | int | Total steps |
+| `step_id` | int | Step index (0-based) |
+| `instruction` | str | user goal |
+| `image_path` | str | Relative path to screenshot |
+| `image_width` / `image_height` | int | Raw resolution |
+| `ui_positions` | str (JSON list) | Normalised \[[y, x, h, w], …] UI element boxes |
+| `result_action_type` | int | Action code |
+| `result_action_text` | str | Text typed (if any) |
+| `result_touch_yx` / `result_lift_yx` | str | Normalised touch coords, `[-1,-1]` if no touch |
+| `duration` | float \| null | Action time (s) |
+
+### 2. Grounding annotations (`cap.jsonl`, `ocr.jsonl`)
+One JSON object per line:
+
+| Field | Example | Description |
+|-------|---------|-------------|
+| `task` | `"bbox2function"` / `"bbox2text"` | Sub-task type |
+| `image` | `"grounding_eval/dataset/images/0.jpeg"` | Screenshot path |
+| `id` | `0` | Unique int id |
+| `abs_position` | `"<x1, y1, x2, y2>"` | Pixel-level bbox |
+| `rel_position` | `"<x1, y1, x2, y2>"` | Normalised bbox |
+| `text` | `"UI元素是一个菜单按钮…"` | Target description / OCR string |
