JPH04310116A - Key push state display system for keyboard - Google Patents

Abstract

PURPOSE:To prevent the deterioration of the input job efficiency of a keyboard by confirming the push states of the function keys on a color display based on the color change of a cursor. CONSTITUTION:When a shift key is pushed, the output of the shift key is given to a shift key push state detecting means 1 which confirms the push of the shift key. Thus the means 1 outputs a cursor color change instruction signal to a cursor color changing means 2. The means 2 changes the color of the cursor into another color designated by the cursor color change instruction signal on a display 5 according to this instruction signal. Then the cursor showing the display positions of the characters, the numeric characters, and the symbols to be inputted next is shown on the display 5 by a cursor display means 4 in a color which shows the shift key push state.

[Problems to be Solved by the Invention] In the above-described method of displaying the pressed state of a key on a conventional keyboard, when the pressed state of a function key is confirmed on the keyboard, the user's line of sight must be turned once to the keyboard to confirm the pressed state. This has the disadvantage of reducing the efficiency of keyboard input work because the key input work that had been done by looking at the display screen must be interrupted. Ta.

[0004] Furthermore, if the pressed state of a function key is checked on the keyboard, if the shape of the cursor displayed on the display is changed, the input character itself may protrude from the cursor. This method has the disadvantage that there are many cases where the judgment is incorrect.

[0005] An object of the present invention is to prevent a decrease in the efficiency of keyboard input work because there is no need to move the line of sight to the keyboard, and to prevent a decrease in the efficiency of keyboard input work by eliminating the need to change the shape of the cursor displayed on the display. To provide a method for displaying a pressed state of a key on a keyboard without causing the character itself to protrude from a cursor and erroneously distinguish the character.

[0006]

[Means for Solving the Problems] The method for displaying the pressed state of a key in the keyboard of the present invention is as follows: (A) When a key is pressed,
A general input key that outputs a first code indicating letters, numbers, and symbols, respectively, and a second code that, when pressed, outputs a second code different from the first code as an output code when the general input key is pressed. (B) cursor display means for displaying a cursor indicating the display position of the next input character, number, and symbol on the display screen; In the display method, (C) a function key press state detection means that detects a press state indicating whether or not the function key is pressed and outputs information indicating the detected press state; (D) the function key The cursor color changing means changes the display color of the cursor according to information indicating the pressed state of the function key outputted from the pressed state detecting means.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a method for displaying the pressed state of a key in a keyboard according to the present invention.

As shown in FIG. 1, the method of displaying the pressed state of a key on the keyboard of this embodiment is as follows: a general input key that outputs a first code indicating a letter, number, or symbol, respectively, when pressed; When a general input key is pressed, a keyboard 3 has a shift key (function key) that outputs a second code different from the first code as an output code when a general input key is pressed.
A display 5 that displays numbers and symbols, a cursor display means 4 that displays a cursor that indicates the display position of the next character, number, and symbol to be input on the screen of the display 5, and a press that indicates whether or not the shift key is pressed. Shift key press state detection means (function key press state detection means) 1 that detects the state and outputs information indicating the detected press state
, cursor color changing means 2 for changing the display color of the cursor in accordance with information indicating the pressed state of the shift key outputted from the shift key pressed state detecting means 1.

Next, the operation will be explained.

In FIG. 1, when a general input key on the keyboard 3 that outputs a code representing a letter, number, or symbol is pressed, a code representing the letter, number, or symbol corresponding to each key is output. , letters, numbers, and symbols are displayed on the display 5, respectively. Next, when you press the Shift key, as long as the Shift key is held down, when you press a general input key, a code indicating letters, numbers, and symbols that is different from when the Shift key is not pressed will be output. . That is, when a general input key that outputs a code indicating a lowercase letter of the alphabet is pressed while the shift key is not pressed, a code indicating the lowercase letter of the alphabet corresponding to that key is output. If the shift key is pressed while in the pressed state, a code indicating the uppercase letter of the same alphabet is output.

According to the present invention, when the shift key is pressed, the output of the shift key is given to the shift key press state detection means 1, and the shift key press state detection means 1 detects that the shift key has been pressed. When the shift key press state detection means 1 detects that the shift key is pressed, it outputs a cursor color change instruction signal to the cursor color change means 2. The cursor color change means 2 changes the color of the cursor on the display 5 to the color specified by the cursor color change instruction signal in accordance with the cursor color change instruction signal, and indicates by the cursor display means 4 that the shift key is pressed. The next character to be entered in the color shown,
A cursor indicating the display position of numbers and symbols is displayed on the display 5.

Further, when the shift key pressed state is restored, the output of the shift key is given to the shift key pressed state detection means 1, and the shift key pressed state detection means 1 detects that the shift key pressed state has been restored, and the shift key is The pressed state detection means 1 outputs to the cursor color changing means 2 a cursor color change instruction signal indicating that the pressed state of the shift key has been restored. As a result, the cursor is displayed on the display 5 in a color indicating that the shift key is not pressed.

[0014] By configuring the system so that the pressed state of a function key can be confirmed by the change in the color of the cursor on the color display, there is no need to move the line of sight to the keyboard, which improves the efficiency of keyboard input work. can prevent a decline in Furthermore, since there is no need to change the shape of the cursor displayed on the display, it is possible to prevent the inputted characters from protruding from the cursor and erroneously identifying the characters.

[0015]

[Effects of the Invention] As explained above, the method for displaying the pressed state of a key in the keyboard of the present invention is configured such that the pressed state of a function key can be confirmed by changing the color of the cursor on the color display. This has the effect that it is not necessary to move the line of sight to the keyboard, and it is possible to prevent a decrease in the efficiency of keyboard input work.

[0016] Furthermore, since there is no need to change the shape of the cursor displayed on the display, it is possible to prevent the inputted characters themselves from protruding from the cursor and erroneously identifying the characters. There is.
