Demonstrations scripts
======================

Collection of command-line scripts for demonstration purpose.

!!! note
      *Consider that all inline commands below have to be executed at the root of ArGaze package folder.*

!!! note
      *Use -h option to get command arguments documentation.*

## Gaze analysis pipeline demonstration

Load ArFrame with a single ArLayer from **demo_gaze_analysis_setup.json** file then, simulate gaze position using mouse pointer to illustrate gaze features.

```shell
python ./src/argaze/utils/demo_gaze_analysis_run.py ./src/argaze/utils/demo/gaze_analysis_pipeline.json
```

## ArUco markers pipeline demonstration

Load ArUcoCamera from **demo_aruco_markers_setup.json** file then, detect ArUco markers into a demo video source and estimate camera pose.

```shell
python ./src/argaze/utils/demo_aruco_markers_run.py ./src/argaze/utils/demo/aruco_markers_pipeline.json -s ./src/argaze/utils/demo_data/demo.mov
```

!!! note
      To reproduce this demonstration with live video source (-s <DEVICE_ID>), print **A3_demo.pdf** file located in *./src/argaze/utils/demo_data/* folder on A3 paper sheet.

## Worn device stream demonstration

Load ArUcoCamera from a configuration file then, stream and process gaze positions and image from any worn eye-tracker device.

### With Tobii Pro Glasses 2 device

To use a Tobii Pro Glasses 2 device, you need to edit **eyetracker_setup.json** file as below with your own parameters values:

```json
{
    "argaze.utils.eyetrackers.TobiiProGlasses2.LiveStream" : {
        "address": "10.34.0.12",
        "project": "MyProject",
        "participant": "NewParticipant",
        "configuration": {
            "sys_ec_preset": "Indoor",
            "sys_sc_width": 1920,
            "sys_sc_height": 1080,
            "sys_sc_fps": 25,
            "sys_sc_preset": "Auto",
            "sys_et_freq": 50,
            "sys_mems_freq": 100
        },
        "pipeline": "demo_aruco_markers_setup.json"
    }
}
```

```shell
python ./src/argaze/utils/pipeline_run.py ./src/argaze/utils/demo/eyetracker_setup.json
```
