<para

<para
>A high value for the acceleration multiplier will lead to large movements of the mouse pointer on the screen, even when you only make a small movement with the physical device.</para>

<tip
><para
>A multiplier between <guilabel

<term
><guilabel
>Pointer threshold</guilabel

<listitem>
<para
>The threshold is the smallest distance that the mouse pointer must move on the screen before acceleration has any effect. If the movement is within the threshold, the mouse pointer moves as if the acceleration were set to <guilabel
>1x</guilabel
>.</para>

<para
>Thus, when you make small movements with the physical device (&eg; mouse), you still have fine control of the mouse pointer on the screen, whereas larger movements of the physical device will move the mouse pointer rapidly to different areas on the screen.</para>

<para
>You can set the threshold value by dragging the slider button or by clicking the up/down arrows on the spin-button to the left of the slider.</para>

<tip
><para
>In general, the higher you set the <guilabel
>Pointer acceleration</guilabel
> value, the higher you'll want to set the <guilabel
>Pointer threshold</guilabel
> value. For example, A <guilabel
>Pointer threshold</guilabel
> of 4 pixels may be appropriate for a <guilabel
>Pointer Acceleration</guilabel
> of 2x, but 10 pixels might be better for 3x.</para
