1. A tactile feedback system for mechanical interfacing with a touch screen work station comprising:
- a keyboard, an attachment member for positioning said keyboard on a touch screen panel; and
a plurality of movable keys resiliently mounted in said keyboard, each of said movable keys having a member for contacting a touch screen region so that when one of said plurality of movable keys is displaced the displacement thereof generates a touch screen signal thereby providing both a tactile user sensation and a touch screen response.

10. A touch screen device;
-
a touch screen panel located on said touch screen device;
a keyboard, said keyboard having a plurality of displaceable keys thereon each of said displaceable member having a contact member thereon;
an attachment member, said attachment member securing said keyboard in either a non-operative position with respect to said touch screen panel or an operative position with respect to said touch screen panel whereby the keyboard is mechanically interfaced with the touch screen panel so that displacement of a key of said plurality of keys directly contacts a specific region of said touch screen thereby providing tactile feedback to an operator. - View Dependent Claims (11, 12, 13, 14)

15. The method of providing tactile feed back to a touch screen system comprising the steps of:
-
positioning a touch screen panel in a ready to use condition;
positioning a keyboard having a mechanical key mechanism in a spaced condition from the touch screen panel; and
transmitting information to the touch screen panel by displacing a selected key on the keyboard to thereby bring a member into physical contact with the touch screen panel. - View Dependent Claims (16, 17, 18, 19)
