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.*

!!! note
    Each demonstration outputs metrics into *_export/records* folder.

## Random context

Load **random_context.json** file to generate random gaze positions:

```shell
python -m argaze load ./src/argaze/utils/demo/random_context.json
```

## OpenCV cursor context

Load **opencv_cursor_context.json** file to capture cursor pointer positions over OpenCV window:

```shell
python -m argaze load ./src/argaze/utils/demo/opencv_cursor_context.json
```

## OpenCV movie context

Load **opencv_movie_context.json** file to playback movie pictures and also capture cursor pointer positions over OpenCV window:

```shell
python -m argaze load ./src/argaze/utils/demo/opencv_movie_context.json
```

## OpenCV camera context

Edit **aruco_markers_pipeline.json** file as to adapt the *size* to the camera resolution and to reduce the value of the *sides_mask*.

Edit **opencv_camera_context.json** file as to select camera device identifier (default is 0).

Then, load **opencv_camera_context.json** file to capture camera pictures and also capture cursor pointer positions over OpenCV window:

```shell
python -m argaze load ./src/argaze/utils/demo/opencv_camera_context.json
```

## Tobii Pro Glasses 2

### Live stream context

!!! note
    This demonstration requires to print **A3_demo.pdf** file located in *./src/argaze/utils/demo/* folder on A3 paper sheet.

Edit **tobii_live_stream_context.json** file as to select exisiting IP *address*, *project* or *participant* names and setup Tobii *configuration* parameters:

```json
{
    "argaze.utils.contexts.TobiiProGlasses2.LiveStream" : {
        "name": "Tobii Pro Glasses 2 live stream",
        "address": "10.34.0.17",
        "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": "aruco_markers_pipeline.json"
    }
}
```

Then, load **tobii_live_stream_context.json** file to find ArUco marker into camera image and, project gaze positions into AOI:

```shell
python -m argaze load ./src/argaze/utils/demo/tobii_live_stream_context.json
```

### Segment playback context

Edit **tobii_segment_playback_context.json** file to select an existing Tobii *segment* folder:

```json
{
    "argaze.utils.contexts.TobiiProGlasses2.SegmentPlayback" : {
        "name": "Tobii Pro Glasses 2 segment playback",
        "segment": "record/segments/1",
        "pipeline": "aruco_markers_pipeline.json"
    }
}
```

Then, load **tobii_segment_playback_context.json** file to find ArUco marker into camera image and, project gaze positions into AOI:

```shell
python -m argaze load ./src/argaze/utils/demo/tobii_segment_playback_context.json
```

## Pupil Invisible

### Live stream context

!!! note
    This demonstration requires to print **A3_demo.pdf** file located in *./src/argaze/utils/demo/* folder on A3 paper sheet.

Load **pupillabs_live_stream_context.json** file to find ArUco marker into camera image and, project gaze positions into AOI:

```shell
python -m argaze load ./src/argaze/utils/demo/pupillabs_live_stream_context.json
```
