Abstract

The present invention offers an improved GUI interface for CAD software to allow users easy access to menus. A user can execute commands and options with little disruption and with minimal hand movement. The keypad is represented on the computer screen and is called a GUFI (Graphical User Friendly Interface) keypad system. The keypad is a menu having a matrix of graphical buttons. A user selects a computer resource with a spatial input device and clicks the proper context button, the GUFI keypad displays only the functions or commands that pertain to the computer resource selected. The unique GUFI keypad system displays functions and commands in an arrayed, not in a pop-up or pull down menu, but in a pattern relating to the keys on the keyboard. Menu items are accessed through a one to one correspondence with the represented keys mapped to similar physically represented keys.

Claims

1. A Graphical User Friendly Interface (GUFI) keypad system for a CAD computer program, comprising:

a menu in a CAD program, display in a computer screen;

a matrix held inside the menu, said matrix also displayed on said computer screen;

a plurality of buttons arranged in said matrix, forming a button matrix displayed on said computer screen;

a plurality of keyboard keys mapped to said plurality of buttons, whereby allowing a user to press one or more keyboard keys, whereby said pressed keyboard key presses its corresponding button activates corresponding CAD functions.

2. A GUFI keypad system as recited in claim 1, further comprising:

a refreshing means to contextually update the button matrix to a new context sensitive user definable button matrix;

a means for a user to manually navigate among a plurality of button matrices.

3. A GUFI keypad system as recited in claim 2, further comprising:

a pointing device such as a mouse or trackball that allows the user to configure the buttons on the button matrix whereby button can be added, moved or deleted.

4. A GUFI keypad system as recited in claim 2, wherein said means for a user to manually navigate among a plurality of button matrices includes pressing a button on a keyboard to cycle through contextually available button matrices.

5. A GUFI keypad system as recited in claim 4, further comprising:

a pointing device such as a mouse or trackball that allows the user to configure the button on the button matrix whereby buttons can be added, moved or deleted.

6. A GUFI keypad system as recited in claim 1, wherein said keyboard keys are mapped to said plurality of buttons according to a three by five matrix which is three high and five wide.

7. A GUFI keypad system as recited in claim 6, wherein said three by five matrix consists of:

keys Q W E R T mapped to a top row of said three by five matrix;

keys A S D F G mapped to a middle row of said three by five matrix;

keys Z X CV B mapped to a bottom row of said three by five matrix.

8. A GUFI keypad system as recited in claim 6, wherein said three by five matrix consists of:

keys Y U I O P mapped to a top row of said three by five matrix;

keys H J K L mapped to a middle row of said three by five matrix;

keys N M , . / mapped to a bottom row of said three by five matrix.

9. A GUFI keypad system as recited in claim 6, wherein said three by five matrix is configured to further display functionality of a button, when a user clicks on said button while pressing a predefined key.
