1. A method for effecting adjustment of a parameter comprising:

  • detecting a change in position of a first object relative to a second object in a sensing region, the first object and the second object being simultaneously present in the sensing region;

    determining a first measurement descriptive of the change in position of the first object relative to the second object in the sensing region;

    indicating a first adjustment to the parameter in response to the change in position of the first object relative to the second object in the sensing region, wherein a magnitude of the first adjustment to the parameter is based on the first measurement;

    detecting a transition event;

    detecting a motion of the first object in the sensing region after the transition event;

    determining a second measurement descriptive of the motion of the first object relative to the sensing region; and

    indicating a second adjustment to the parameter in response to the detecting the motion of the first object and a continuous presence of at least one of the first and second objects in the sensing region between a beginning of the change in position of the first object relative to the second object in the sensing region and a beginning of the motion of the first object in the sensing region, wherein a magnitude of the second adjustment to the parameter is based on the second measurement.
