1. A method comprising:

  • identifying a contact on a surface of a trackpad of a computing device;

    calculating a value of a first speed of movement of the contact along the surface of the trackpad;

    allowing movement of a cursor on a display device included in the computing device if the value of the first speed of movement of the contact along the surface of the trackpad is determined to be greater than a slow threshold speed;

    blocking movement of the cursor on the display device if the value of the first speed of movement of the contact along the surface of the trackpad is determined to be equal to or less than the slow threshold speed;

    subsequent to a blocking of the movement of the cursor on the display device, calculating a second speed of movement of the contact along the surface of the trackpad;

    calculating a value of an accumulated distance moved by the contact along the surface of the trackpad; and

    continuing the blocking of the movement of the cursor on the display device based on;

    determining that the value of the second speed of movement of the contact along the surface of the trackpad is greater than the slow threshold speed and less than a fast threshold speed, anddetermining that the value of the accumulated distance moved by the contact along the surface of the trackpad is less than a threshold distance value.
