1. A digitizer system comprising:

  • a designated sensing area comprising a plurality of sensing lines for sensing an electromagnetic signal emitted by a stylus interacting with the digitizer system;

    circuitry for detecting output from the plurality of sensing lines and for determining an interacting position of the stylus in the designated sensing area based on the output detected; and

    a peripheral area contiguous to the designated sensing area, the peripheral area comprising;

    a plurality of conductive elements for connecting the plurality of sensing lines to the circuitry; and

    at least one auxiliary sensing line extending over the peripheral area in the vicinity of the plurality of conductive elements and connected to the circuitry;

    wherein the at least one auxiliary sensing line is operable to sense the electromagnetic signal when it is emitted over the peripheral area; and

    wherein the circuitry is operable to detect output from the at least one auxiliary sensing line.
