Input.EyesTracked

static BtnState EyesTracked{ get }

Description

If eye hardware is available and app has permission, then this is the tracking state of the eyes. Eyes may move out of bounds, hardware may fail to detect eyes, or who knows what else!

On Flatscreen when MR sim is still enabled, this will report whether the user is simulating eye input with the Alt key.

Permissions

For UWP apps, permissions for eye tracking can be found in the project’s .appxmanifest file under Capabilities->Gaze Input.
For Xamarin apps, you may need to add an entry to your AndroidManifest.xml, refer to your device’s documentation for specifics.

Examples

if (Input.EyesTracked.IsActive())
{
	// Intersect the eye Ray with a floor plane
	Plane plane = new Plane(Vec3.Zero, Vec3.Up);
	if (Input.Eyes.Ray.Intersect(plane, out Vec3 at))
	{
		Default.MeshSphere.Draw(Default.Material, Matrix.TS(at, .05f));
	}
}
