Abstract
Keyboard systems for interfacing with a touchscreen. The keyboard includes: a plurality of contact members formed of electrically conducting material, each of the contact members having first and second sides; and a plurality of keys. Each key has an electrically conducting key-pad unit and a resilient member, where the resilient member is adapted to maintain the key-pad unit in a spaced part relationship relative to a corresponding one of the contact members. The first side of each contact member is in constant contact with a particular portion of the touchscreen. The key-pad unit is adapted to contact the second side of a corresponding one of the contact members when pressed by a foreign object, to thereby form an electrically conducting path between the foreign object and the particular portion of the touchscreen.
