Summary: | A user input passive device for interaction with a touchscreen of an interactive display device includes a housing including: a conductive shell and a non-conductive supporting surface coupled to the conductive shell. The user input further includes an impedance circuit having a desired impedance at a desired frequency, a first conductive plate mounted on the non-conductive supporting surface, electrically isolated from the conductive shell, and a second conductive plate mounted on the non-conductive supporting surface, electrically isolated from the conductive shell and the first conductive plate. The first terminal of the impedance circuit is coupled to the first conductive plate and a second terminal of the impedance circuit is coupled to the second conductive plate. When the user input passive device is used with the touchscreen, a perimeter of the conductive shell, and the first and second conductive plates are in close proximity to an interactive surface of the touchscreen. |
