Visualizations
Some plugins have the capability to overlay additional visualizations on top of the scene camera video. These plugins can have different ways to customize the appearance.
Gaze Visualizations
Visualize the gaze positions with a circle or a crosshair for each gaze position, you can add multiple instances of gaze visualizations to build your own custom visualization.
The following parameters can be set within the Gaze Data plugin for both circle and crosshair visualizations:
| Parameter | Description |
|---|---|
| Use offset | If enabled, gaze points are rendered using the gaze offset. If disabled, raw gaze positions are used. |
| Aggregation | Controls how gaze points are displayed over the scene camera frame: Raw draws all gaze points; Mean, Median, First, and Last draw only one point per frame. |
| Show when worn | If enabled, gaze points are shown when Neon is detected as worn. |
| Show when not worn | If enabled, gaze points are shown when Neon is detected as not worn. |
| Color | Select the gaze point color and opacity. |
If using a circle visualization, you can additionally set the following parameters:
| Parameter | Description |
|---|---|
| Radius | The radius of the circle around the gaze point. |
| Stroke width | The thickness or width of the stoke in pixels. |
If using a crosshair visualization, you can set the following parameters:
| Parameter | Description |
|---|---|
| Size | The size of the crosshair around the gaze point. |
| Gap size | The distance in pixels to offset the interior cross endpoints from the gaze position. A value of 0 will make the crosshairs intersect the gaze position. |
| Stroke width | The thickness or width of the stoke in pixels. |
| Draw dot | If enabled, it draws the gaze point at the center of the crosshair. |
Fixation Visualizations
Similarly to gaze visualizations, you can visualize fixation points with a circle for each fixation position.
You can set the following parameters within the Fixations plugin:
| Parameter | Description |
|---|---|
| Use offset | If enabled, fixation points are rendered using the gaze offset. If disabled, raw fixations positions are used. |
| Adjust for optic flow | If enabled, fixation points are rendered with optic flow adjustment, reducing the impact of scene motion on fixations. |
| Color | Select the fixation circle color and opacity. |
| Base radius | Scaling factor for fixation circle size based on fixation duration. |
| Stroke width | The thickness or width of the stoke in pixels. |
| Font size | Sets the font size of the fixation ID labels. |
Eye Overlay
You can also visualize the eye videos on top of the scene camera video using the Eye Overlay plugin. You can resize and drag the eye overlay to position it anywhere on the video player, allowing you to customize the layout of your visualizations.
You can set the following parameters:
| Parameter | Description |
|---|---|
| Opacity | The opacity of the overlay eye video image. 1.0 is opaque and 0.0 is transparent. |
| Border width | The thickness or width of the border around the eye video image. |
| Border color | Select the border color and opacity for the eye video image. |
Others
Other plugins may have different visualizations and customizable parameters, check the documentation of each plugin for more details on the available visualizations and how to customize them.
