## How to use EyeBlink Motion Adapter

<details>

<summary>What is the difference between EyeBlink and EyeBlinkAll Motion Adapters?</summary>

If you use the EyeBlink motion adapter, you can use the size values (left/rightEye) of both eyes separately. Using EyeBlinkAll, you can combine the size values of both eyes and send them to one Controller.

</details>

1\. In the <mark style="color:purple;">`Project window`</mark>, go to <mark style="color:purple;">`Assets > MYTYKit > MotionAdapter > Eye > Bone`</mark>, click and drag the <mark style="color:purple;">`EyeBlink`</mark> or <mark style="color:purple;">`EyeBlinkAll`</mark> prefab into the <mark style="color:purple;">`MotionAdapterGroup`</mark> object in the <mark style="color:purple;">`Hierarchy window`</mark>. You can change the name of the Motion Adapter object If you want to.&#x20;

2\. Click on the ◉icon next to a Template input box and select the <mark style="color:purple;">`SimpleFaceParam`</mark> template to be applied.&#x20;

{% hint style="info" %}
If nothing appears when you click the ◉ icon, it may be due to the following:\
The DefaultMotionTemplate or the MediapipeMotionPack prefab is not in the Hierarchy window\
→ Check [#1.-add-defaultmotiontemplate](https://myty.gitbook.io/myty-kit/make-animation/9.-apply-motion-tracking/..#1.-add-defaultmotiontemplate "mention") and [#2.-add-mediapipemotionpack](https://myty.gitbook.io/myty-kit/make-animation/9.-apply-motion-tracking/..#2.-add-mediapipemotionpack "mention")
{% endhint %}

3\. To set which Controller to connect the leftEye or rightEye motion data, click the ◉ icon next to TargetController. ◉ icon will bring up a Controller list from which you can select an option.

{% hint style="info" %}
If nothing appears when you click the ◉ icon, it may be due to the following:

The appropriate Script(s) are not applied to the Controller \
→ Check [#2.-create-controller](https://myty.gitbook.io/myty-kit/8.-myty-kit-controllers#2.-create-controller "mention")
{% endhint %}

4\. When all the elements are set, press the <mark style="color:purple;">`▶️(Play)`</mark> button to check the avatar preview.

### Advanced Options

You can control the stabilizing method in the Advanced Options. To get more advanced information about this, refer to 👉 [stabilizing-method](https://myty.gitbook.io/myty-kit/make-animation/9.-apply-motion-tracking/advanced-documentation/stabilizing-method "mention").

* <mark style="color:purple;">`Is Damping`</mark>: The latest input becomes more dominant than the older input.
* <mark style="color:purple;">`Is Stabilizing`</mark>: It enables to detection of the moment of arrival of new data, and it makes the stabilization process much more rigorous.
* <mark style="color:purple;">`Is Use Damped Input To Stabilizer`</mark>: Whether to use damped input as input for stabilizer
* <mark style="color:purple;">`Damping Factor`</mark>: If Damping Factor=1, then the algorithm is just average. If Damping Factor becomes larger, it means that the latest input becomes more dominant than the older input.&#x20;
* <mark style="color:purple;">`Damping Window`</mark>: The amount of input data frames to configure the damping algorithm.
* <mark style="color:purple;">`Stabilize Method`</mark>:  Which method to apply to stabilize algorithm.
