Keyboard with keys for moving cursor
First Claim
1. A signal generator for sending information to a computer monitor to effect proportional movement of a pointer or cursor on that monitor, comprising:
- a plurality of depressable keys on said signal generator, for the sending of electrical signals to said monitor through an electrical circuit; and
a further electrical circuit arranged between at least two of said plurality of depressable keys on said signal generator and said signal generator, to effect motion in a cursor on said monitor, when said plurality of at least two of said keys are given a sideways direction of motion.

Abstract
The present invention comprises a signal generator for sending an electrical signal from an expandable, flexible layer of material, the signal generator comprising an upper layer of flexible, resilient material and a lower layer of flexible, resilient material which between them define a cavity for enclosing an expandable material such as a cellular foam or gas, whereupon localized distortion of one of the layers of flexible material, effects a signal generation within the structure, which is transmissible through a proper circuit to an outside electrical device. A circuit may be arranged adjacent a plurality of said keys which senses when several of said keys are depressed in a skewed or sideways manner, so as to effect movement of a cursor or pointer on a monitor in communication with a processing unit and said keyboard.

7. A method of generating an electrical signal in order to effect a movement of a cursor on a computer monitor, comprising the steps of:
-
arranging a plurality of depressable keys on a keyboard so that when any of said keys are depressed, an electrical signal is sent through a first electrical circuit to a processing unit and to a monitor for display of that signal thereon; and
arranging a further sideways motion sensing electrical circuit with respect to at least two of said keys, so as to send a further electrical signal to said monitor to move a cursor in a desired direction when a plurality of said keys having said further circuit are moved with any component of sideways motion. - View Dependent Claims (8, 9, 10)

11. A method of generating an electrical signal from a keyboard in order to effect movement of a cursor on a monitor, comprising the step of:
moving sideways a plurality of keys arranged on said keyboard so as to send a signal from a sideway motion sensor arranged with respect to each of said plurality of keys, to said monitor, to induce cursor motion in said monitor. - View Dependent Claims (12, 13, 14, 15, 16)
