1. A method for indicating a desired user interface navigation task based upon a motion detected by an input device, wherein the motion comprises a first section having a first direction and a second section having a second direction substantially opposing the first direction, the method comprising the steps of:

  • receiving a sequence of two-dimensional signals wherein a first plurality of the two-dimensional signals corresponds to the first section of the motion and a second plurality of the two-dimensional signals corresponds to the second section of the motion;

    processing at least a portion of the sequence of two-dimensional signals to determine distance measurements; and

    providing a plurality of one-dimensional output signals to thereby indicate the desired user interface navigation task, wherein each of the plurality of one-dimensional output signals is provided in response to at least one of the two-dimensional signals;

    has a magnitude based upon at least a portion of the distance measurements; and

    has a common polarity.
