* <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.
