Summary of the Invention

Problems to be Solved by the Invention

[0005] However, conventional scientific calculators forced single-line input in all areas, including spreadsheets. This reduced the usable area for range input in spreadsheet applications, resulting in poor usability due to the need for scrolling. Furthermore, even commands that allow natural display, such as integral operations and logarithms, were limited to single-line input, making input time-consuming. Additionally, commands that only allow natural display, such as repeating decimals, could not be entered (NOP).

[0006] Therefore, the present invention aims to improve user convenience by enabling natural input corresponding to the display mode of mathematical formulas. [Means for solving the problem]

[0007] The information processing device according to this invention comprises a display control means for displaying a first input reception screen on a display unit for receiving information including at least a number, an operator, or a symbol in a first input reception method, and a determination means for determining whether the received information input satisfies predetermined conditions, wherein the display control means, when determined by the determination means to satisfy the predetermined conditions, displays a second input reception screen on the display unit for receiving the information input in a second input reception method different from the first input reception method.

[0008] The display control method according to this invention is characterized by including the steps of: displaying a first input reception screen on a display unit for receiving information including at least a number, an operator, or a symbol in a first input reception method; determining whether the received information input satisfies predetermined conditions; and, if it is determined that the predetermined conditions are met, displaying a second input reception screen on the display unit for receiving the information input in a second input reception method different from the first input reception method.

[0009] The program according to this invention includes a display control function that displays a first input reception screen on the display unit for receiving information including at least a number, an operator, or a symbol in a first input reception method, and a determination function that determines whether the received information input satisfies predetermined conditions, wherein the display control function, when determined by the determination function to satisfy the predetermined conditions, displays a second input reception screen on the display unit for receiving the information input in a second input reception method different from the first input reception method.

[Figure 8]This is a flowchart illustrating the operation of a scientific calculator 100 and a smartphone 200 according to a modified version of this embodiment. [Modes for carrying out the invention]

[0012] A. Embodiment The best mode for carrying out the present invention will be described below with reference to the drawings. However, the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, but the scope of the invention is not limited to the embodiments and illustrated examples below.

[0013] Figure 1 is a block diagram showing the configuration of a scientific calculator 1 emulated by an information processing device according to this embodiment. Figure 2 is a schematic diagram showing an example of the screen display of a scientific calculator 1 emulated by an information processing device according to this embodiment. The scientific calculator 1 is emulated as an application on an information processing device such as a computer. The scientific calculator 1 consists of a control unit 2, an arithmetic processing unit 3, a storage unit 4, a display control unit 5, a main display screen 6, a sub-display screen 7, and operation keys 8. The control unit 2 controls the operation of the entire scientific calculator 1. The arithmetic processing unit 3 realizes the calculation functions of the scientific calculator 1. The storage unit 4 holds data associated with the arithmetic processing by the arithmetic processing unit 3. The display control unit 5 displays mathematical formulas, numerical values, calculation results, etc., entered by single-line input and / or natural input on the main display screen 6 and / or sub-display screen (pop-up screen) 7, which are emulated on the display 10 of the information processing device. The operation keys 8 are operation keys (or a physical keyboard; not shown) that are emulated on the display 10.

[0014] The display 10 is a physical display device provided by the information processing device. As shown in Figure 2, the display 10 shows a scientific calculator 1, emulated by the information processing device, with an LCD display and various keys, in a state that simulates the appearance of an actual calculator. The main display screen 6 corresponds to the display unit of a normal scientific calculator and is displayed by default. The main display screen 6 is used when entering mathematical formulas (functions, etc.), numbers, operators, symbols, etc., on a single line. On the other hand, the secondary display screen 7 is displayed as a pop-up screen on the display 10 when natural input corresponding to the display format of the mathematical formula is possible or when selected by the user, and displays in a natural form corresponding to the display format of the mathematical formula. The user can naturally input numbers, operators, symbols, etc., for the mathematical formula displayed on the secondary display screen 7 according to the display format of the mathematical formula. The operation keys 8 correspond to the various keys of the scientific calculator (numeric keys, function / symbol / operation keys, function keys, etc.) displayed on the display 10, as shown in Figure 2.

[0015] The display 10 may also be equipped with a touch panel. In this case, various operations can be performed, similar to a regular scientific calculator, such as inputting desired formulas, numbers, and operators, by directly touching the operation keys 8 displayed on the display 10 with a finger or a dedicated pen. Even if there is no touch panel, similar operations can be performed using a physical keyboard (not shown).

[0016] In particular, in this embodiment, when there is any input from the user, the control unit 2 determines whether the input satisfies a predetermined condition. The predetermined condition is whether the input of mathematical expressions (functions, etc.), numerical values, operators, symbols, etc. in a natural form corresponding to the display mode of the mathematical expression is more conducive to the recognition of the mathematical expression, that is, whether it is a natural input. For example, integral operations, fractional operations, log operations, spreadsheet calculations, etc. are determined as inputs that satisfy the predetermined conditions. In principle, when the control unit 2 does not satisfy the predetermined conditions, that is, when the operation is a problem-free operation with one-line input (simple multiplication, division, addition, and subtraction), it controls the main display screen 6 that is default-displayed on the display 10 to input and display mathematical expressions, numerical values, operators, etc. On the other hand, when the control unit 2 satisfies the predetermined conditions, that is, when the input is suitable for natural input (integral, fractional operation, log operation, spreadsheet calculation, etc.), it pop-up displays the sub-display screen 7 on the display 10, displays the mathematical expression in a natural form on the sub-display screen 7, and controls the input and display of numerical values, operators, etc. in a natural form for the displayed mathematical expression.

[0017] Note that whether to display and input on the main display screen 6 or on the sub-display screen 7 is automatically determined by the control unit 2 according to whether the predetermined conditions are satisfied as described above, but it can also be arbitrarily switched by the user.

[0018] B. Operation of the Embodiment FIG. 3 and FIG. 4 are flowcharts for explaining the operation of the scientific calculator 1 emulated by the information processing apparatus according to this embodiment. FIGS. 5 and FIG. 6 are schematic diagrams showing display examples and input methods of the scientific calculator 1 emulated by the information processing apparatus according to this embodiment.

[0019] First, as shown in Fig. 5(a), the control unit 2 activates the main display screen 6 for single-line input by the display control unit 5 (step S10). The example shown in Fig. 5(a) shows the state where the spreadsheet function is activated on the scientific calculator 1. Next, the control unit 2 determines whether a key related to any operation has been input from the operation keys 8 (step S12). If it is not a key related to an operation (NO in step S12), the control unit 2 executes other processing according to the input key (step S14). On the other hand, if it is a key related to some operation (YES in step S12), the control unit 2 determines whether a specific function key has been input (step S16). Here, the specific function key corresponds to an input related to an operation for which natural input (display) such as spreadsheet calculation, integration, fraction, etc. is preferred. And when it is not a specific function key, that is, when it is an input related to an operation that can also be a single-line input (such as simple multiplication, division, addition, and subtraction), the process proceeds to the single-line input processing after step S18.

[0020] <Single-line input processing> In the single-line input processing, first, according to the input from the operation keys 8 by the user, the control unit 2 inputs a mathematical formula or a numerical value by single-line input from the main display screen 6 in order to perform normal operations (such as multiplication, division, addition, and subtraction) (step S18). Fig. 5(b) shows the state where the user designates a batch input of cells from A1 to A3 in the table.

[0021] During the single-line input, the control unit 2 determines whether the sub-display screen 7 has been tapped (selection instruction) (step S20). If the sub-display screen 7 has not been activated, of course, the determination is NO. And if the sub-display screen 7 has not been tapped (NO in step S20), it is determined whether a determination key or an input cancellation key (such as clear, all clear, etc.) has been input from the operation keys 13 (step S22). And if neither the determination key nor the input cancellation key has been input (NO in step S22), the process returns to step S12 and the single-line input continues. And when the determination key or the input cancellation key is input during the single-line input (YES in step S20), the control unit 2 releases the input state (step S24).

[0022] <Natural Input Processing> If a specific function key is entered during single-line input (YES in step S16), the process proceeds to the natural input process from step S28 onwards as shown in Figure 4. If the control unit 2 determines that it is a specific function key (YES in step S16), the control unit 2, with the display control unit 5, deactivates (grays out) the main display screen 6 (step S28). Next, the control unit 2 determines whether the sub-display screen 7 is already activated on the display 10 (step S30). If the sub-display screen 7 is already activated (YES in step S30), the process proceeds to step S34. If the sub-display screen 7 is not activated (NO in step S30), the display control unit 5 activates the sub-display screen 7 and displays it as a pop-up on the display 10 (step S22), and the process proceeds to step S34.

[0023] For example, as shown in Figure 5(c), when the user presses the "∫" key, since the "∫" key is a specific function key, natural input is not possible in single-line input mode. Therefore, the sub-display screen 7 is opened to display "∫" as a natural input. At this time, the gradation of the main display screen 6 of the scientific calculator 1 is displayed faintly (gray), and the input of the "∫" key is reflected. Also, as shown in Figure 5(c), the pop-up sub-display screen 7 displays an integral symbol for integral calculation, and a box indicated by a dotted line is displayed where the variable (numerical value) is to be entered.

[0024] Next, the control unit 2, in response to user input from the operation keys 8, inputs mathematical formulas and numerical values ​​via natural input from the sub-display screen 7 in order to perform calculations such as spreadsheet calculations, integrals, and fractions (step S34). The user simply needs to input the numbers in order as the cursor automatically moves to the input box. Alternatively, the user may tap (select) the input location. When the user inputs "x" on the sub-display screen 7, it is reflected on the main display screen 6 of the scientific calculator 1, as shown in Figure 6(d). Furthermore, when the user inputs "1" and "2" above and below the symbol "∫" as the range of integration on the sub-display screen 7, it is reflected on the main display screen 6 of the scientific calculator 1, as shown in Figure 6(e). In this way, natural input makes it easy to visually recognize which variable (numerical value) is being input.

[0025] The control unit 2 determines whether the main display screen 6 has been tapped (selection instruction) during natural input (step S36). If the main display screen 6 has not been tapped (NO in step S36), it determines whether the OK key or the input cancellation key (clear, all clear, etc.) has been pressed from the operation key 8 (step S38). If neither the OK key nor the input cancellation key has been pressed (NO in step S38), it returns to step S34 and continues natural input.

[0026] If the OK key or the input cancellation key is pressed during natural input (YES in step S38), the control unit 2, via the display control unit 5, activates the main display screen 6 of the scientific calculator 1 (returning it to its original grayscale) (step S40), and closes the sub-display screen 7 that was popping up on the display 10 (step S40). If the equals key ("=") is pressed during natural input, the control unit 2 instructs the arithmetic processing unit 3 to perform calculations based on the entered mathematical expression and numerical values. The arithmetic processing unit 3 performs calculations based on the entered mathematical expression and numerical values ​​using the memory unit 4, etc. The control unit 2, via the display control unit 5, displays the calculation result on the main display screen 6 of the scientific calculator 1. After that, the process returns to step S24 as shown in Figure 3, and the input state is canceled.

[0027] For example, when the user touches "=" during natural input as shown in Figure 6(e), the calculation result is reflected in cells A1 to A3 of the table on the main display screen 6 of the scientific calculator 1. Then, the pop-up sub-display screen 7 is closed, and the grayscale of the main display screen 6 of the scientific calculator 1 returns to its original state.

[0028] <Switching between natural input and single-line input> Furthermore, if the sub-display screen 7 is tapped in step S20 during the single-line input described above, the sub-display screen 7 is activated (changed from grayed out to normal display) and the main display screen 6 is deactivated (changed from normal display to grayed out) (step S26). After that, the natural input process proceeds from step S34 onwards in Figure 4.

[0029] On the other hand, if the main display screen 6 is tapped in step S36 during the natural input described above, the main display screen 6 is activated (from gray display to normal display) and the sub-display screen 7 is deactivated (from normal display to gray display) (step S44). After that, the natural input processing from step S12 onwards in Figure 4 proceeds.

[0030] Thus, by displaying a secondary display screen 7 that enables natural input separately from the main display screen 6, user convenience can be improved. Furthermore, it is possible to switch between natural input and single-line input with simple operations, allowing for easy switching between the two modes during input. In addition, even with single-line input, it is possible to input and calculate spreadsheets, integrals, fractions, etc., so the usability will not be compromised for users who are accustomed to conventional input methods.

[0031] In the embodiment described above, input is performed on either the main display screen 6 or the sub-display screen 7. However, the invention is not limited to this, and both the main display screen 6 and the sub-display screen 7 may be activated, so that input on one screen is reflected on the other screen.

[0032] C. Variations Next, a modified example of this embodiment will be described. Figure 7 is a schematic diagram showing a usage configuration of a scientific calculator 100 and a smartphone (external device) 200 according to a modified example of this embodiment. In this modified example, the scientific calculator 100 is not an application emulated on an information processing device, but a physically independent scientific calculator. The scientific calculator 100 has wireless communication capabilities (Wi-Fi® or Bluetooth®) and, as shown in Figure 7, can connect to the smartphone 200 via wireless communication.

[0033] The scientific calculator 100 is equipped with an LCD display 101 and operation keys 102. The smartphone 200 is equipped with a larger, touch-operable LCD display 201 compared to the LCD display 101 of the scientific calculator 100. The smartphone 200 operates its LCD display 201 as a secondary display screen that allows for natural input according to instructions from the scientific calculator 100. Numerical values ​​and other data entered from the smartphone 200 are transmitted to the scientific calculator 100 via wireless communication. The scientific calculator 100 receives the data transmitted from the smartphone 200 and performs calculations according to the entered mathematical formulas.

[0034] Figure 8 is a flowchart illustrating the operation of the scientific calculator 100 according to a modified example of this embodiment. The scientific calculator 100 determines whether a key related to some kind of calculation has been entered from the operation key 102 (step S50). If it is not a key related to an calculation (NO in step S50), the scientific calculator 100 performs other processing corresponding to the entered key (step S52). On the other hand, if it is a key related to some kind of calculation (YES in step S50), the scientific calculator 100 determines whether a specific function key has been entered (step S54). If it is not a specific function key, that is, if it is a key related to an calculation that can be entered in one line (simple addition, subtraction, multiplication, division) (NO in step S54), the aforementioned one-line input processing is performed (step S70).

[0035] <Natural input> On the other hand, if it is a specific function key (YES in step S54), the scientific calculator 100 starts wireless communication with the smartphone 200 (step S56). Next, the scientific calculator 100 deactivates (grays out) the screen of the liquid crystal display unit 101, which corresponds to the main display screen (step S58).

[0036] Next, the scientific calculator 100 transmits formulas, numbers, operators, etc., entered by the user via the operation keys 102 to the smartphone 200 via wireless communication. The smartphone 200 receives the formulas, numbers, operators, etc., transmitted from the scientific calculator 100 and displays them on the LCD display 201 in a display mode that corresponds to natural input (step S60). At this time, the LCD display 201 of the smartphone 200 displays a screen suitable for natural input as described above. For example, as shown in Figure 5(c), an integral symbol (integral "∫") is displayed for integral calculations, and boxes indicated by dotted lines are displayed where variables (numbers) should be entered. The user simply needs to enter the numbers in order as the cursor automatically moves to the boxes where input should be made (Figures 6(d), (e)). Alternatively, the user may specify the input location by tapping (selecting) the LCD display 201 of the smartphone 200. When the equals key ("=") is pressed, the scientific calculator 100 performs calculations based on the entered formula and numerical values, and displays the calculation result on the liquid crystal display unit 101 of the scientific calculator 100, as shown in Figure 6(f).

[0037] Next, the scientific calculator 100 determines whether an OK key or an input cancellation key (such as clear or all clear) has been pressed from the operation key 102 during natural input (step S62). If neither an OK key nor an input cancellation key has been pressed (NO in step S62), it returns to step S60 and continues natural input using the LCD display 201 of the smartphone 200.

[0038] Then, when the confirm key or the input release key is pressed during natural input (YES in step S62), the scientific calculator 100 activates the screen of the liquid crystal display unit 101, which corresponds to the main display screen (step S64), and terminates wireless communication with the smartphone 200 (step S66). After that, the input state is released (step S68).

[0039] According to the embodiment described above, when a specific function key, such as a mathematical formula for which natural input is preferred, is entered, a sub-display screen 7 suitable for an input acceptance method different from the main display screen 6 for single-line input is activated, and natural input corresponding to the display mode of the mathematical formula is made possible using the sub-display screen 7, thereby improving user convenience.

[0040] According to the embodiment described above, the main display screen 6 is displayed at a predetermined position on the scientific calculator 1 of the display 10, and the sub-display screen 7 is displayed as a pop-up at a different position from the main display screen 6. This allows for easy and natural input, improving user convenience.

[0041] According to the embodiment described above, the main display screen is displayed on the liquid crystal display unit 101, and the sub-display screen is displayed on the liquid crystal display unit 201 of the smartphone 200 connected via wireless communication. This allows for easy and natural input, improving user convenience.

[0042] According to the embodiment described above, when the main display screen 6 is displayed in its normal display mode and the sub-display screen 7 is displayed, the main display screen 6 is displayed in a gray display mode different from the normal display mode. This makes it easy to determine which screen is active, thereby improving user convenience.

[0043] According to the embodiment described above, when input from a predetermined specific function key is received, it is determined that natural input corresponding to the display mode of the mathematical formula will be performed using the sub-display screen 7, so the system can automatically switch to natural input, thereby improving user convenience.

[0044] According to the embodiment described above, when the sub-display screen 7 is displayed and natural input is being performed, a marker indicating that the sub-display screen 7 is being displayed is shown on the main display screen 6. This makes it easy to identify which screen is active and which is the input target, thereby improving user convenience.

[0045] In addition, in the embodiments and modifications described above, when the sub-display screen 7 (liquid crystal display unit 201) is displayed, some kind of mark or the like may be displayed on the main display screen 6 (liquid crystal display unit 101) or an existing mark (such as a mark indicating the establishment of a Bluetooth® connection) may be made to blink so that the user can understand that natural input is being accepted on the sub-display screen 7 (liquid crystal display unit 201). By displaying such marks on the main display screen 6, it becomes easy to determine whether or not the secondary display screen 7 is being displayed, thereby improving user convenience.
