The threshold is the smallest distance that the mouse pointer must move on the screen before acceleration has any effect. If the movement is smaller than the threshold, the mouse pointer moves as if the acceleration was set to 1X; thus, when you make small movements with the physical device, there is no acceleration at all, giving you a greater degree of control over the mouse pointer. With larger movements of the physical device, you can move the mouse pointer rapidly to different areas on the screen.
De fersnellingsdrompel is de lytste ôfstân dy de mûsoanwizer ôflizze moat foardat de fersnelling mar ienich effekt hat. As de beweging lytser is dan de drompel, dan beweegd de mûs har as is de fersnellings op 1x ynsteld. Dus as jo mei jo fysike apparaat lytse bewegings meitsje, dan is der gjin inkele fersnelling, wêrtroch jo mear kontrôle hawwe oer de mûsoanwizer. By grutter bewegings fan it fysike apparaat kinne jo de mûsoanwizer fluch nei oare gebieden op it skerm bringe.
