To an auxiliary device.

Devices that can perform computer functions independently (desktop computers, notebook computers, PDAs, PDA phones, etc.) are hereinafter referred to as "electronic devices." And a display device for displaying the result on the screen. Typical input devices used in such electronic devices are a keyboard and a mouse or a keypad, and a representative display device is a monitor such as an LCD or a CRT.

By the way, the conventional keyboard has a predetermined standard keyboard and can input only the keys provided in the keyboard, and the conventional mouse provides only a limited function of inputting a command by clicking a specific portion on the screen displayed on the monitor. In the case of the keyboard, the high-end keyboard has keyboards other than standardized keyboards, and specific functions can be assigned to these keyboards according to a user's definition, but the functions are limited. It only provides a function for assisting in inputting commands.

In order to compensate for these disadvantages, an auxiliary input device has been proposed to define and input various commands according to the user's convenience.

1 is a view showing the configuration of such a conventional auxiliary input device.

The auxiliary input device 100 includes a casing 110 having a rectangular frame shape and a plurality of buttons 120 provided on the front surface of the casing 110. Typically, the computer 50 is composed of a main body 51, a monitor 52, a keyboard 53 and a mouse 54, the auxiliary input device 100 by this keyboard 53 and the mouse 54 Allows the user to define the function of each button 120 to more quickly implement the various functions that can be performed.

This driver program allows to assign various programs or various commands installed in the user's computer 50 to each button 120. Therefore, the user can execute the operation predefined by the user by pressing the corresponding button 120 in the same manner as pressing the shortcut button.

In FIG. 1, the buttons in the first column include 'Open' for opening a document, 'Save' for saving the current document state, 'Save As' for saving the current document under another name, and saving the current document. Functions such as 'print' for printing and 'edit' for editing the current document are assigned. This is an example of assigning various instructions that can be executed in this word processor while using a program such as MS Word.

The buttons in the second row are assigned program names such as MS Word, Excel, and Internet Explorer. The user can run the Excel program, for example, by pressing a button assigned to Excel. This is an example of assigning commands to each button to execute the program itself.
