## Introduction

Built-in gestures require parameters that can be modified from GestureDetectionConfiguration. These parameters are always relative to hand size.

## Variables

* **Max Local Rot Z:** What value must the Z-axis of the local rotation of a bone have in order to consider that its main rotation lerp equals to 1.
* **Min Local Rot Z:** What value must the Z-axis of the local rotation of a bone have in order to consider that its main rotation lerp equals to 0.

#### Fist

* **Max Palm Rel Distance:** Distance between the tip of a finger and the horizontal line of the palm, relative to the scale of the hand, above which the lerp value of the finger gesture PalmLine equals to 0.
* **Min Palm Rel Distance:** Distance between the tip of a finger and the horizontal line of the palm, relative to the scale of the hand, under which the lerp value of the finger gesture PalmLine equals to 1.

#### Pinch

* **Max Pinch Rel Distance:** Distance between the tip of a finger and the tip of the thumb, relative to the scale of the hand, above which the lerp value of the finger gesture Pinch equals to 0.
* **Min Pinch Rel Distance:** Distance between the tip of a finger and the tip of the thumb, relative to the scale of the hand, under which the lerp value of the finger gesture Pinch equals to 1.
* **Min Flex Lerp To Disable Pinch:** Pinch gesture shouldn't be triggered if finger tip is too close to its knuckle. This value is a threshold of Flex gesture under which Pinch gesture can be detected so they are not detected simultaneously.

#### Flex

* **Min Flex Rel Distance:** Distance between the tip of a finger and its knucle, relative to the scale of the hand, under which the lerp value of the finger gesture Flex equals to 1.

#### Gesture intention

* **Min Time To Intention:** Number of seconds that a gesture must be active to be considered intentionally active (only appliable for Grasp and Pinch gestures).
