# Basic Tremor Reduction algorithms

Component Type: Processor (Subcategory: Singal Shaping)

This plugin contains three algorithms for user hand tremor reduction: Arithmetic Mean, Outlier Reduction and Exponential Smoothing. The Arithmetic Mean algorithm calculates the cursor position as an average of the past n cursor positions. N is defined by the bufferSize parameter. The Outlier Reduction algorithm keeps the maximum distance between two followed cursor positions. The maximum distance is defined by the maxDistance parameter. If the distance between two cursor positions is greater than maxDistance, it is reduced to the value of maxDistance. The Exponential Smoothing algorithm implements the Exponential smoothing (opens new window) technique. The factor parameter defines the Exponential Smoothing and the degree parameters define the degree of the equation.
