Abstract
A touch device has a plurality of row conductors and a plurality of column conductors. Located proximate to where the row conductors and the column conductors interact are additional conductor arrangements that are able to increase the capacitive interaction that occurs on the touch device. The conductor arrangements are formed from different column conductors and row conductors located proximate to the where the row and column conductors interact and form different arrangements.
Claims20
An apparatus comprising:
- at least one row conductor adapted to transmit a signal generated by a signal generator;
- at least one column conductor positioned in proximity to the at least one row conductor and operably connected to a receiver such that a touch event proximate to the at least one row conductor and the at least one column conductor causes a change in coupling between the at least one row conductor and the at least one column conductor;
- a second row conductor not connected to the signal generator, wherein the second row conductor is located proximate to the at least one row conductor and the at least one column conductor such that a touch event proximate to the second row conductor causes a change in coupling, wherein the change in coupling is processed to determine touch events;
- and
- a second column conductor not connected to the receiver, wherein the second column conductor is located proximate to the at least one row conductor and the at least one column conductor such that a touch event proximate to the second column conductor causes a change in coupling, wherein the change in coupling is processed to determine touch events.

A touch sensitive device comprising:
- at least one row conductor adapted to transmit a signal generated by a signal generator;
- at least one column conductor positioned in proximity to the at least one row conductor and operably connected to a receiver such that a touch event proximate to the at least one row conductor and the at least one column conductor causes a change in coupling between the at least one row conductor and the at least one column conductor;
- a second row conductor angled at a non-zero angle with respect to the at least one row conductor, wherein the second row conductor is located proximate to the at least one row conductor and the at least one column conductor such that a touch event proximate to the second row conductor causes a change in coupling, wherein the change in coupling is processed to determine touch events;
- and
- a second column conductor angled at a non-zero angle with respect to the at least one column conductor, wherein the second column conductor is located proximate to the at least one row conductor and the at least one column conductor such that a touch event proximate to the second column conductor causes a change in coupling, wherein the change in coupling is processed to determine touch events.
