Abstract:
1. A keyboard system for a digital computer, the keyboard system comprising: a housing defined by a top surface area and a lower surface area, the upper surface area having a keyboard section, a function key section, a stationary mouse, and a numeric key section cooperatively arranged on the top surface area of the housing; the stationary mouse ergonomically designed to support the hand in a natural position while in use and being disposed to the far right of the housing for a right handed person or being disposed to the far left of the housing for a left handed person; the keyboard section having keys for generating key signals, the keys being substantially arranged in a standard QWERTY or DVORAK typewriting key format; the function key section having keys configured to generate application or system specific key signals; the numeric key section having keys configured to generate numeric key signals; a communication means for transmitting the generated key signals of to the digital computer; a switch configured to switch the numeric key section between a keyboard mode and a calculator mode; a small display screen operationally mounted on the top surface of the housing near the numeric key section; when the switch is in the keyboard mode, the key signals generated by the numeric key section are transmitted to the digital computer; when the switch is in the calculator mode, a local calculator driver processes the key signals generated by the numeric key section and displays the results on the display screen; and a power source for generating an electrical current; and; a stationary mouse for a right handed person being disposed to the right of the numeric key section and having a casing defined by an upper surface, a left side, a right side, and a flat bottom surface area; the upper surface area dimension to fit within the user's hand; the upper surface area including a vertex point, a front section and a back section; a raised crown area located at the vertex point of the upper surface area; the front section being curved and extending forward from the crown area to a front curved edge, the back section being curved and extending backward from the crown area to a back curved edge which is dimensioned to accommodate the length of the lower palm region while the user's hand is in an operating position on the mouse; a navigation stick configured to generate precise screen cursor control movement key signals, without utilizing a track ball disposed within the bottom surface area and a supporting left mouse button, the navigation stick positioned in the upper left corner of the forward section for operation by the index finger, the navigation stick extending vertically upward a slight distance above the top surface area; the navigation stick configured to generate left click key signals for application or system programs when depressed in a downward direction; a right click button configured to generate right click key signals for application programs or system programs, the right click button positioned in the upper right corner of the forward section for operation by the middle finger; and a scroll button configured to generate screen scroll movement key signals for application programs or system programs, the scroll button positioned laterally within a curved recessed portion disposed on the left side of the casing within for operation by the right thumb while in a natural position.
