1. An apparatus, comprising:

  • a resistive element positionable on a first surface, the resistive element formed from a plurality or portions;

    a plurality of leads configured to provide a voltage to each of the plurality of portions of the resistive element;

    a contact element positionable on a second surface, the contact element configured to contact the resistive element to detect a voltage at a contact position, the detected voltage being associated with a position of the second surface relative to the first surface; and

    a voltage controller configured to selectively provide a voltage to each of the plurality of portions of the resistive element according to a position of the contact element relative to the resistive element.
