Abstract
A digitizer system includes a designated sensing area comprising a plurality of sensing lines for sensing an electromagnetic signal emitted by a stylus, 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 includes a plurality of conductive elements for connecting the sensing lines to the circuitry and at least one auxiliary sensing line extending over the peripheral area in the vicinity of the conductive elements and connected to the circuitry. The auxiliary sensing line senses the electromagnetic signal when it is emitted over the peripheral area and the circuitry detects output from the at least one auxiliary sensing line.
