# GUI Grounding Pre-training Data for OS-ATLAS
This document describes the acquisition of the pre-training data used by OS-ATLAS.

**Notes:** In GUI grounding data, the position of the target element is recorded in the `bbox` key, represented by `[left, top, right, bottom]`. 
Each value is a [0, 1] decimal number indicating the ratio of the corresponding position to the width or height of the image.

The data we released is divided into three domains: mobile, desktop and web.

All annotation data is stored in JSON format and each sample contains:
* `img_filename`: the interface screenshot file
* `instruction`: human instruction
* `bbox`: the bounding box of the target element corresponding to instruction

Some data also contains a `data_type`, which records the type of an element in its structured information, if it can be obtained.

### Mobile data

This part of data is stored under the *mobile_domain* directory. Our mobile grounding data consists of four parts.

#### AMEX
Android Multi-annotation EXpo (AMEX) is a comprehensive, large-scale dataset designed for generalist mobile GUI-control agents [1].

The annotation data is stored in

-'amex_raw.json'

Due to the single file size limitation of Hugging Face datasets, we stored the Amex images in *zip* format and split them into several sub-files. 

- `amex_images_part_aa`
- `amex_images_part_ab`
- `amex_images_part_ac`

You need to first merge these split files back into the original file and then extract the contents.

```
cat amex_images_part_* > amex_images.zip
7z x amex_images.zip -aoa -o/path/to/extract/folder
```

#### UIBert

This is a dataset extended from Rico dataset [2] for two tasks: similar UI component retrieval and referring expression component retrieval [3].

The annotation data is stored in

- `uibert_raw.json`

The UIBert images are stored in

- `UIBert.zip`

#### Widget Captioning and RICOSCA
Widget Captioning data are collected by [4]. 
RICOSCA is a dataset automatically labeled using Android VH in [5]

The annotation data is stored in

- `widget_captioning.json`
- `ricosca.json`

The rico images are stored in 

- `rico_imgs.zip`

#### Android_world_data

This part of data are sampled from a android environment for building and benchmarking autonomous computer control agents [6].

The annotation data is stored in

- `aw_mobile.json`

The rico images are stored in 

- `mobile_images.zip`

### Desktop data

This part of data is stored under the *desktop_domain* directory. All of the desktop grounding data is collected from the real environments of personal computers running different operating systems. Each image is split into multiple sub-images to enhance data diversity.
Our mobile grounding data consists of three parts.
