Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information device such as a graphic scientific calculator, and more particularly to a device having improved operability.

[0002]

2. Description of the Related Art Conventionally, a graphic scientific calculator has been used for calculation,
It has functions such as statistical calculation, graph drawing, statistical graph drawing, and program execution. These functions can reach the result after going through several key operation procedures. Although the graphic scientific calculator has many keys, the number of keys is not enough due to the many types of operations, so one key has multiple contents, a menu is displayed, and one of the contents is displayed. It is made to be selected.

FIG. 6 is a diagram showing the surface of a graphic scientific calculator. There is a display device 4 at the top and a key input device 5 at the bottom. The display device 4 is composed of, for example, a liquid crystal panel having 96 dots in the horizontal direction and 64 dots in the vertical direction (16 digits × 8 rows).

For example, when displaying a graph of a function, the following procedure is conventionally performed. First, while pressing the second function key 5a, the setup key 5b is pressed to display a setup menu. This menu includes settings for a coordinate system (such as rectangular coordinates and polar coordinates) and settings for angular units (such as degrees and radians). These settings need not be changed, but if set incorrectly, it is natural that a correct answer cannot be obtained (for example, when 30 degrees is calculated as 30 radians).
Next, the user presses a key 5c for inputting a function expression.
1 = X (X−2) and Y2 = X are input. Next, the key 5d for inputting the window value is pressed, and the left end (Xmin), right end (Xmax), lower end (Ymin),
Coordinate values of the upper end (Ymax) are respectively -2, 5, and-
Input as 2,5. Next, when the key 5e for instructing the display of the graph is pressed, the function graph is displayed on the display device 4.

[0005]

However, the conventional graphic scientific calculator has the following disadvantages. a) The operation procedure is complicated, and it is difficult to understand. b) It is difficult to find the key to press. I don't understand the meaning of the key. I don't know which key appears on the menu for an operation. c) Simple contents, for example, execution after creating a program, may be a complicated operation procedure.

[0006] Therefore, it is difficult for anyone except those who have mastered the operation of the graphic scientific calculator to use it. For junior high and high school students, the purpose is to study math and science, but for most students, graphic scientific calculators are just learning how to use teaching materials. The present invention
It aims to improve the operability of information devices such as graphic scientific calculators.

[0007]

An information device according to the present invention includes an explanation subroutine for displaying an operation guide to a user and an operation subroutine for performing a key operation by the user. Means for sequentially proceeding the procedure by pressing a key; and pressing the second key causes the next explanation subroutine when the procedure is in the explanation subroutine, and the next operation subroutine when the procedure is in the operation subroutine. Means for advancing the procedure.

Pressing the first key means simultaneously pressing a specific key and a right cursor moving key, and pressing the second key means pressing the specific key and the down cursor moving key. By simultaneously pressing the keys, it is possible to match the sense of the person who advances the procedure with the key arrangement.
Further, by providing a means for sequentially retreating the procedure by pressing the third key, the procedure can be retreated.

When the fourth key is depressed, a means for retreating the procedure to the preceding explanation subroutine when the procedure is in the explanation subroutine and to the preceding operation subroutine when the procedure is in the operation subroutine is provided. With the provision, the procedure can be retreated for each of the explanation subroutine or the operation subroutine. Further, the present invention is a computer-readable recording medium in which a program for causing a computer to function as the information device is recorded.

[0010]

FIG. 1 is a block diagram showing a system configuration according to an embodiment of the present invention. The CPU 1 executes a program such as a calculation process, and the ROM 2 stores a program necessary for the process, and also stores a procedure sequence group 21, an explanation subroutine group 22, an operation subroutine group 23, and the like. The RAM 3 stores temporary data required for processing. A display device 4 and a key input device 5 are provided on the surface of the computer. Display device 4
Are connected to the CPU 1 via the display control unit 6. The data corresponding to all the dots of the display device 4 is the display R
Although stored in the AM 7, data is provided from the CPU 1. The key input device 5 is connected to the C
It is connected to PU1.

FIG. 2 is a diagram for explaining a procedure sequence group 21, an explanation subroutine group 22, and an operation subroutine group 23 in the ROM 2. The procedure sequence group 21 includes a procedure sequence 1, a procedure sequence 2, and so on. The procedure column is a list in which subroutine names to be called and executed are sequentially arranged. The explanation subroutine group 22 includes explanation subroutine 1, explanation subroutine 2,
, And the subroutine names are A001 and A0, respectively.
02, ... The explanation subroutine is a program including displaying an operation guide to a user. The operation subroutine group 23 includes an operation subroutine 1, an operation subroutine 2,...
001, B002,... The operation subroutine is a program for the user to press a key or select from a menu. The operation subroutine may be activated by the user pressing a key or selecting from a menu.

For example, procedure sequence 1 relates to graph drawing, and FIG. 3 shows a data structure thereof. However, actually, the numbers are not always arranged in order as shown in the figure. A0
01 is an explanation subroutine for displaying an explanation that the coordinate system needs to be set, and B001 is an orthogonal coordinate,
This is an operation subroutine for setting operations such as polar coordinates. A002 is an explanation subroutine for displaying an explanation that the angle unit needs to be set, and B002 is an explanation subroutine.
This is an operation subroutine for setting operations such as degrees and radians. FIGS. 4 (a) and 4 (b) show A002 and B0
It is a figure showing the example of a display in 02. A003 is an explanation subroutine for displaying an explanation that a function expression needs to be input, and B003 is an operation subroutine for actually inputting a function expression. A004 is an explanation subroutine for displaying an explanation that the window value needs to be set, and B004 is an operation subroutine for actually inputting the window value. A005 is a last explanation subroutine, and B005 is a subroutine for displaying a graph of the result.

FIG. 5 is a diagram showing the relationship between the explanation subroutine and the operation subroutine in the sequence 1 and the depression of the cursor movement key. The right arrow indicates that the right cursor movement key 5f is pressed while the second function key 5a is being pressed. The downward arrow means that the down cursor movement key 5i is pressed while the second function key 5a is being pressed. The left arrow indicates that the left cursor movement key 5g is pressed while the second function key 5a is being pressed. The upward arrow means that the up cursor movement key 5h is pressed while the second function key 5a is being pressed. In FIG. 5, where there is no arrow, the operation of the arrow is invalid. When the right arrow is pressed,
The subroutine to be executed is moved below the procedure sequence 1 shown in FIG. When the left arrow is pressed, the subroutine to be executed is shifted to the sequence 1 above. When the down arrow is pressed, if the procedure is in the explanation subroutine, the next explanation subroutine (data two steps below the data in the procedure column 1 or data with A next to it) is added to the operation subroutine. In step (1), the subroutine to be executed is moved to the next operation subroutine (data two steps below the data in procedure column 1 or data following B). When the upward arrow is pressed, if the procedure is in the explanatory subroutine, the preceding explanatory subroutine (the data two steps above the data in the procedure column 1 or the data with an A in front of it) is used as the operating subroutine. Is described in the previous explanation operation subroutine (B two steps above the data in procedure column 1 or B
(The data marked with), and move the subroutine to be executed.

Next, an operation example of the present embodiment will be described. When the graph drawing is started, the procedure sequence 1 in FIG. 3 is selected, the subroutine A001 is executed, and an explanation that the coordinate system needs to be set is displayed. Since then
While pressing the second function key 5a, press the right cursor movement key 5
By repeatedly pressing f, B001, A002, B002, A003,..., B
The subroutine of 005 is sequentially executed, and the graph drawing can be ended. In A001, if it is determined that the operation of B001 is not necessary, the user presses the down cursor movement key 5i while holding down the second function key 5a. In that case, the routine proceeds to the next A002 in the explanation subroutine. B0
If it is desired to change the settings after reaching 05, the user presses the up cursor movement key 5h while holding down the second function key 5a. At that time, the previous operation subroutine B004
The routine returns to, for example.

The present invention is not limited to the above embodiment. The function of moving the subroutine to be executed to the previous one and the function of moving the subroutine to be executed to the same one before may be omitted. The present invention may be a computer-readable recording medium in which a program for causing a computer to function as the information device is recorded.

[0016]

According to the present invention, in the use of a graphic scientific calculator or the like, simply pressing a specific key, the display of the operation explanation is displayed, and the next operation is repeated.
