# Smoothing with OpenTabletDriver

## Overview

OpenTabletDriver lets you configure smoothing via plug-ins.

## Installing the Slimy Scylla plug-in

Instructions for installing Slimy Scylla are here: [Slimy Scylla](/drawtab/guides/drivers/opentabletdriver/otd-plugin-slimyscylla.md)

## Position smoothing

There are several filters that involve smoothing the position of the pen.

* Position Smoothing Moving Average
* Position Smoothing Pulled String
* Position Smoothing Exponential Moving Average

The one I recommend is **Position Smoothing Exponential Moving Average**.

## Configuring Position Smoothing Exponential Moving Average

This is what the configuration looks like:

If you want to enable the filter, click **Enable Slimy Scylla ...** at the top, then click **Apply**.

**Amount** = how much smoothing to apply. The range is 0.0 to 1.0. Try `0.1` to start.

**Always Apply to Hover** = leave this unchecked.
