Embodiments will be described below with reference to the drawings. FIG. 1 is a diagram illustrating an example of a configuration of a communication system including electronic devices according to an embodiment. A communication system 1 shown in FIG. 1 has a computer 100 and an electronic device 200 . The calculator 100 is, for example, a calculator (electronic desktop calculator). An example of a calculator is a scientific calculator having a functional calculation function. Further, the electronic device 200 is an electronic device having character input and word search functions, such as a smart phone, a tablet terminal, and an electronic dictionary. The computer 100 and the electronic device 200 are connected so as to communicate with each other. A communication method between the computer 100 and the electronic device 200 is, for example, a short-range wireless communication method such as BLE (Bluetooth (registered trademark) Low Energy). The communication method between the computer 100 and the electronic device 200 is not limited to the BLE method.

FIG. 2 is a diagram showing an example of the configuration of the computer 100. As shown in FIG. Calculator 100 has processor 101 , memory 102 , operation keys 103 , display 104 and communication module 105 . Calculator 100 may be a variety of electronic devices having numerical calculation functions other than calculators. Moreover, the computer 100 may have a configuration other than that shown in FIG.

The processor 101 is a processor that operates as a control unit that controls various operations of the computer 100 . Processor 101 may be a CPU, ASIC, FPGA, or the like. Also, the processor 101 may be composed of two or more processors.

Memory 102 includes RAM and ROM. The RAM is volatile memory and can operate as a storage unit. The RAM is used as a work memory or the like for temporarily storing various data in the processor 101 . ROM is non-volatile memory. Various programs such as a calculation program for executing various calculation functions are stored in the ROM. In addition, the ROM stores values of various constants used in function calculations and the like in association with code number values. When the user enters a corresponding code number after performing a specific constant input operation, the processor 101 reads the symbol of the constant stored in the ROM and displays it on the display 104 . FIG. 3 is a diagram showing an example of a correspondence table between code numbers and symbols representing constants. In the example of FIG. 3, for example, the code number, the symbol representing the constant, the unit of the constant, and the value of the constant are associated with each other. Code number 1 in FIG. 3 is associated with symbol G representing the universal gravitational constant. When an input is made by the user to call the constant of code number 1, processor 101 causes display 104 to display symbol G. FIG. The processor 101 also uses the value of the universal gravitational constant associated with the symbol G to perform calculations. Needless to say, constants other than those shown in FIG. 3 may be stored in the ROM. The ROM may store not only the code numbers and constants in association with each other, but also the code numbers and formulas in association with each other. Note that the constants stored in the ROM are not necessarily limited to scientific constants. Constants used in other fields such as statistics may be stored in ROM. Similarly, formulas are not limited to those used for scientific formulas, and formulas used in other fields such as mathematical formulas may be stored in the ROM. Furthermore, the constants shown in FIG. 3 may be added at appropriate timing.

The operation keys 103 include various physical keys for the user to operate the computer 100 . The operation keys 103 perform various specific functions such as numeric keys for inputting numerical values, operator keys for inputting operators, calculation execution keys for executing calculations, clearing of inputs, and input of constants. may include physical keys such as function keys for When an operation using operation keys 103 is accepted, an input signal corresponding to the operation is transmitted to processor 101 .

The display 104 is a display unit such as a liquid crystal display. A display 104 provides various displays related to the calculator function.

The communication module 105 is a module for the computer 100 to communicate with the electronic device 200 . Communication module 105 may be, for example, a BLE communication module.

FIG. 4 is a diagram showing an example of the configuration of the electronic device 200. As shown in FIG. Electronic device 200 has processor 201 , memory 202 , storage 203 , input device 204 , display 205 and communication module 206 . Electronic device 200 may have a configuration other than that shown in FIG.

The processor 201 is a processor that operates as a control unit that controls various operations of the electronic device 200 . Processor 201 may be a CPU, ASIC, FPGA, or the like. Also, the processor 201 may be composed of two or more processors.

Memory 202 includes RAM and ROM. The RAM is volatile memory and can operate as a storage unit. The RAM is used as a working memory or the like for temporarily storing various data in the processor 201 . ROM is non-volatile memory. Various programs such as a boot program for the electronic device 200 are stored in the ROM.

The storage 203 is a storage medium such as flash memory and hard disk. Various application programs that operate in the electronic device 200 are stored in the storage 203 . This application program includes the input support program 2031 of the computer 100 . The input support program 2031 may be downloaded from a predetermined server and installed. A database 2032 is also stored in the storage 203 . The database 2032 is a database that shows correspondence relationships between character strings representing the names of constants, symbols representing the constants, and character strings representing the names of various formulas and the formulas. FIG. 5 is a diagram showing an example of a correspondence table between character strings representing names of constants and symbols representing constants as an example of the database 2032 . In the example of FIG. 5, for a constant such as the universal gravitational constant, a character string representing a general name of the constant, a symbol representing the constant, a unit of the constant, and a value of the constant are associated with each other. On the other hand, for formulas such as the law of universal gravitation, a character string representing a general name of the formula is associated with the formula. Here, the database 2032 does not necessarily have to be stored in the storage 203 . Database 2032 may be stored in an external server or the like accessible from electronic device 200 . Further, database 2032 may be associated with code numbers used by computer 100 .

The input device 204 is various interfaces such as a touch panel, a keyboard, and a mouse for the user to operate the electronic device 200 . When an operation using the input device 204 is accepted, an input signal corresponding to the operation is transmitted to the processor 201 .

The display 205 is a display device such as a liquid crystal display. The display 205 provides various displays.

Communication module 206 includes modules for electronic device 200 to communicate with computer 100 . For example, when electronic device 200 and computer 100 perform BLE communication, communication module 206 may be a BLE communication module. Communication module 206 may also include a module for connecting to a network such as the Internet.

Next, the operation of the communication system 1 will be explained. FIG. 6 is a flow chart showing the operation of the computer 100 in the communication system 1. As shown in FIG. Here, the operation of FIG. 6 is the operation after communication between the computer 100 and the electronic device 200 is established. For example, when the computer 100 is powered on and the input support program 2031 of the electronic device 200 is activated, connection processing necessary for BLE communication is started. At this time, for example, the electronic device 200 performs necessary connection processing as a central device in BLE communication, and the computer 100 performs necessary connection processing as a peripheral device in BLE communication.

In step S<b>1 , the processor 101 of the computer 100 transmits mathematical formula data already input by the user (the mathematical formula data displayed on the display 104 ) to the electronic device 200 via the communication module 105 . After that, the process moves to step S2. Also, if there is no formula that has already been entered, transmission does not have to be performed.

At step S2, the processor 101 determines whether or not there is a key input by the user. When it is determined in step S2 that there is a key input by the user, the process proceeds to step S3. When it is determined in step S2 that there is no key input by the user, the process proceeds to step S5.

In step S3, the processor 101 determines whether or not the key input by the user is a power off key input. When it is determined in step S3 that the key input by the user is not the power-off key input, the process proceeds to step S4. In step S3, when it is determined that the key input by the user is a power-off key input, the processor 101 powers off the computer 100 and terminates the processing of FIG.

In step S4, the processor 101 executes processing according to the user's key input. For example, when a numeric key is entered, the processor 101 causes the display 104 to display the corresponding numeric value. Also, for example, when an operator key is input, the processor 101 causes the display 104 to display the corresponding operator. Also, when a calculation execution key is input, the processor 101 performs calculation and causes the display 104 to display the calculation result. Also, when a function key is entered, the processor 101 causes the corresponding function to be executed. After that, the process returns to step S1.

In step S<b>5 , processor 101 determines whether data has been received from electronic device 200 . When it is determined in step S5 that data has been received from electronic device 200, the process proceeds to step S6. When it is determined in step S5 that data has not been received from electronic device 200, the process returns to step S1.

At step S<b>6 , processor 101 updates the display of display 104 based on the data received from electronic device 200 . After that, the process returns to step S1.

FIG. 7 is a flowchart showing the operation of electronic device 200 when input support program 2031 is activated. In step S101, the processor 201 of the electronic device 200 causes the display 205 to display an initial screen. FIG. 8 is a diagram showing an example of the initial screen. As shown in FIG. 8, the initial screen includes a formula display field 301 , a label selection field 302 and a search keyword input field 303 . After displaying the initial screen, the process proceeds to step S102.

In step S<b>102 , the processor 201 displays the formula 3011 in the formula display field 301 based on the formula data already input in the computer 100 received from the computer 100 . As a result, the display on the display 104 of the computer 100 and the display on the numerical expression display column 301 are displayed in the same manner. Furthermore, the processor 201 displays a cursor 3012 at the end of the displayed mathematical expression 3011 . It should be noted that only the cursor 3012 may be displayed when no formula data is transmitted from the calculator 100 .

In step S<b>103 , the processor 201 determines whether or not the user has performed a tap operation on the display 205 . When it is determined in step S103 that there is a tap operation, the process proceeds to step S104. A tap operation is a tap on any one of the formula display field 301, the label selection field 302, and the search keyword input field 303 on the initial screen. When it is determined in step S103 that there is no tap operation, the process proceeds to step S111.

In step S<b>104 , the processor 201 determines whether or not the tap position is in the formula display field 301 . When it is determined in step S104 that the tap position is in the formula display field 301, the process proceeds to step S105. When it is determined in step S104 that the tap position is not in the formula display field 301, the process proceeds to step S106.

In step S105, the processor 201 changes the position of the cursor 3012 displayed in the formula display field 301 to the tap position. After that, the process moves to step S111. Constants and formulas (details of which will be described later) transmitted from electronic device 200 are entered at a position on display 104 corresponding to the position of cursor 3012 .

In step S<b>106 , the processor 201 determines whether or not the tap position is the label selection field 302 . When it is determined in step S106 that the tap position is in the label selection field 302, the process proceeds to step S107. When it is determined in step S106 that the tap position is not in the label selection column 302, the process proceeds to step S110.

In step S107, the processor 201 causes the label selection field 302 to display a list of labels in, for example, a drop-down list format. Labels are set in advance to limit the search range when searching using search keywords, and include, for example, "mechanics", "physics", "chemistry", and "statistics".

At step S108, the processor 201 determines whether or not the label has been determined (selected). The processor 201 waits until it is determined in step S108 that the label has been determined. It should be noted that if a location other than the label selection column 302 is tapped without determining the label, the process may return to step S103. If it is determined in step S108 that the label has been determined, the process proceeds to step S109.

In step S<b>109 , the processor 201 displays the determined label in the label selection field 302 . Processor 201 also ends the display of the drop-down list. After that, the process moves to step S111. When the label is determined, the search processing described later is performed only within the range of the field of the label. On the other hand, if the label is not determined, search processing is performed in the entire range without narrowing down the range.

In step S110, the processor 201 performs search processing. After the search process, the process moves to step S111. Search processing will be described later.

In step S111, the processor 201 determines whether or not the input support program 2031 should be terminated. For example, when the user performs a specific operation to terminate the input support program 2031, it is determined that the input support program 2031 is to be terminated. If it is determined in step S111 that the input support program 2031 is not terminated, the process returns to step S103. When it is determined in step S111 to terminate the input support program 2031, the processor 201 terminates the processing of FIG.

FIG. 9 is a flowchart showing search processing. In step S<b>201 , the processor 201 displays a software keyboard near the search keyword input field 303 .

In step S202, the processor 201 determines whether or not a character has been input using the software keyboard. The processor 201 waits until it is determined in step S202 that a character has been input. It should be noted that the search process may be terminated when a portion other than the software keyboard is tapped without character input. In this case, the processor 201 performs the process of step S111 in FIG. If it is determined in step S202 that a character has been input, the process proceeds to step S203.

In step S<b>203 , the processor 201 displays the entered characters in the keyword entry field 303 .

At step S204, the processor 201 refers to the database 2032 to search for constants and formulas that partially match the input characters. In step S204, the processor 201 may search for constants and formulas that exactly match the input characters.

At step S205, the processor 201 causes the search results to be displayed. The processor 201 displays a list of partially matched constants and formulas as search candidates 304, as shown in FIG. FIG. 10 shows an example in which the characters "universal gravitation" are entered in the search keyword input field 303, and the universal gravitation constant, which is a constant that partially matches this "universal gravitation", and the formula of the law of universal gravitation are displayed as search candidates 304. . If there are no constants or formulas that partially match, the search candidates 304 may not be displayed, or a message indicating that there is no search result may be displayed.

In step S206, the processor 201 determines whether or not one of the search candidates 304 has been determined (selected), such as by tapping one of the search candidates 304 by the user. When it is determined in step S206 that one of the search candidates 304 has been determined, the process proceeds to step S207. When it is determined in step S206 that one of the search candidates 304 has not been determined, the processor 201 terminates the processing of FIG.

At step S207, the processor 201 determines whether or not the determined search candidates are constant. When it is determined in step S207 that the determined search candidates are constant, the process proceeds to step S208. When it is determined in step S207 that the determined search candidate is not a constant, that is, it is a formula, the process proceeds to step S209.

In step S208, the processor 201 executes constant processing. At step S209, the processor 201 executes formula processing. After step S208 or step S209, the processor 201 terminates the process of FIG.

FIG. 11 is a flowchart showing constant processing. In step S301, the processor 201 causes the screen of the display 205 to transition to a constant display screen. After the transition of the display screen, the process moves to step S302. FIG. 12 is a diagram showing an example of a constant display screen. As shown in FIG. 12 , the constant display screen includes a constant display column 305 , a valid digit input column 306 and a send button 307 . The constant value determined by the user is displayed in the constant display column 305 together with the symbol. The example of FIG. 12 shows a display example when the universal gravitational constant is determined. A significant digit input field 306 is a display field for inputting significant digits for calculation using the determined constant. A send button 307 is a software button for accepting an instruction to send the determined constants to the computer 100 .

At step S302, the processor 201 determines whether the send button 307 has been tapped by the user. When it is determined in step S302 that the send button 307 has been tapped, the process proceeds to step S307. When it is determined in step S302 that the send button 307 has not been tapped, the process proceeds to step S303.

In step S303, the processor 201 determines whether the user has tapped the valid digit input field 306 or not. When it is determined in step S303 that the valid digit input field 306 has been tapped, the process proceeds to step S304. When it is determined in step S303 that the valid digit input field 306 has not been tapped, the process returns to step S302.

In step S<b>304 , the processor 201 displays a software keyboard near the effective digit input field 306 . The software keyboard here may be a keyboard with only numerical keys.

In step S305, the processor 201 determines whether or not a numerical value has been entered using the software keyboard. The processor 201 waits until it is determined in step S305 that a numerical value has been input. If it is determined in step S305 that a numerical value has been input, the process proceeds to step S306.

At step S306, the processor 201 causes the input numerical value to be displayed in the significant digit input field 306. FIG. Processor 201 also sets the input numerical value to the determined constant significant digits. After that, the process returns to step S302. It should be noted that the processor 201 may display an error when a numerical value not suitable as a valid digit is input. Also, an initial value of significant digits may be determined in advance for each constant. In this case, if there are no significant digits by the user, an initial value of significant digits may be displayed in step S306.

At step S307, the processor 201 determines whether significant digits have been entered. When it is determined in step S307 that valid digits have been input, the process proceeds to step S308. When it is determined in step S307 that valid digits have not been input, the process returns to step S302. In this case, the processor 201 may display on the display 205 a message or the like prompting the user to enter significant digits. If the initial value of significant digits is predetermined for each constant, it may be determined that the initial value of significant digits has been input in step S307. When the initial value of the significant digits is predetermined for each constant, the processor 201 may cause the value of the constant with the initial value of the significant digits set to be displayed in the constant display field 305 . In this case, the processor 201 may not display the effective digit input field 306 on the constant display screen, and may omit the processing of steps S303 to S307.

In step S<b>308 , the processor 201 transmits constant data to the computer 100 through the communication module 206 . After that, the processor 201 terminates the processing of FIG. Here, constant data includes symbol data representing the constant, constant unit data, constant value data, and significant digit data. Alternatively, the constant data may include only code number data and significant digit data corresponding to the constant. This allows the processor 101 to perform calculations using the constant data retrieved by the electronic device 200 (transmitted from the electronic device 200).

FIG. 13 is a flowchart showing formal processing. In step S401, the processor 201 causes the screen of the display 205 to transition to the official display screen. After the transition of the display screen, the process moves to step S402. FIG. 14 is a diagram showing an example of the official display screen. As shown in FIG. 14, the official display screen includes an official display field 308 , a valid digit input field 309 and a send button 310 . The formula display column 308 displays the formula determined by the user. The example of FIG. 14 shows a display example when the formula of the law of universal gravitation is determined. Here, the variables in the formula are displayed in bold or the like so that the user can identify them. For example, in the example of FIG. 14, "M" and "m" (mass of two objects) and "r" (distance between two objects) other than the universal gravitational constant G are displayed in bold. The display of the variable portion is not limited to the display in bold, and may be displayed in a different color or the like. A significant digit input field 309 is a display field for inputting significant digits for calculation using the determined formula. Send button 310 is a software button for accepting an instruction to send the determined formula to computer 100 .

At step S402, the processor 201 determines whether the send button 310 has been tapped by the user. When it is determined in step S402 that the send button 310 has been tapped, the process proceeds to step S410. When it is determined in step S402 that the send button 310 has not been tapped, the process proceeds to step S403.

At step S403, the processor 201 determines whether the user has tapped the valid digit input field 309 or not. When it is determined in step S403 that the effective digit input field 309 has been tapped, the process proceeds to step S404. When it is determined in step S403 that the effective digit input field 309 has not been tapped, the process proceeds to step S407.

In step S<b>404 , the processor 201 displays a software keyboard near the valid digit input field 309 . The software keyboard here may be a keyboard with only numerical keys.

In step S405, the processor 201 determines whether or not a numerical value has been entered using the software keyboard. The processor 201 waits until it is determined in step S405 that a numerical value has been input. If it is determined in step S405 that a numerical value has been input, the process proceeds to step S406.

In step S406, the processor 201 causes the entered numeric value to be displayed in the significant digits entry field 309. FIG. Processor 201 also sets the entered numerical value to the determined significant digits of the formula. After that, the process returns to step S402. It should be noted that the processor 201 may display an error when a numerical value not suitable as a valid digit is input. Also, an initial value of significant digits may be determined in advance for each formula. In this case, if there are no significant digits by the user, an initial value of significant digits may be displayed in step S406.

In step S407, the processor 201 determines whether or not the variable position in the formula display field 308 has been tapped. For example, in the case of the formula of the law of universal gravitation, whether or not any part of 'M' and 'm' (the mass of two objects) and 'r' (the distance between two objects) other than the universal gravitational constant G is tapped is determined. When it is determined in step S407 that the location of the variable has been tapped, the process proceeds to step S408. If it is not determined in step S407 that the location of the variable has been tapped, the process returns to step S402.

At step S408, the processor 201 transforms the formula to solve for the determined variables. That is, processor 201 transforms the formula to move the determined variables to the left side. For example, if variable 'M' is determined, processor 201 transforms the formula for the law of universal gravitation to solve for 'M'.

In step S409, the processor 201 updates the display of the formula display field 308 with the transformed formula. After that, the process returns to step S402.

At step S410, the processor 201 determines whether significant digits have been entered. When it is determined in step S410 that significant digits have been input, the process proceeds to step S411. When it is determined in step S410 that valid digits have not been entered, the process returns to step S402. In this case, the processor 201 may display on the display 205 a message or the like prompting the user to enter significant digits. Here, if the initial value of significant digits is predetermined for each formula, it may be determined that the initial value of significant digits has been input in step S410. When the initial value of the significant digits is predetermined for each formula, the processor 201 may not display the significant digits input field 309 on the display screen of the formula, omitting the processing of steps S403 to S406. good too. In this case, when it is determined in step S402 that the send button 310 has not been tapped, the process proceeds to step S407.

In step S<b>411 , the processor 201 uses the communication module 206 to transmit the formula data (specifically, the data on the right side of the formula) to the computer 100 . After that, the processor 201 terminates the processing of FIG. Here, the official data includes official data and significant figure data. Alternatively, the formula data may include code number data corresponding to the formula, variable data on the right side, and significant digit data.

On the other hand, the processor 201 may use a search engine or the like to inquire whether there is a constant or formula that partially or completely matches the search keyword input to an external server or the like. As a result, even constant or formula data not registered in the database 2032 can be transmitted to the computer 100 . In this case, the processor 201 may include new code number data for use with the calculator 100 in the constant and formula data. Constants or formula data registered in the database 2032 but not registered in the computer 100 can also be transmitted to the computer 100 . Even in this case, the processor 201 may include new code number data for use in the calculator 100 in the constant and formula data. As a result, computer 100 can continue to use unregistered constants and formulas even after communication with electronic device 200 is disconnected.

Further, electronic device 200 may store a history of past searches. In this case, the electronic device 200 presents the past search history to the user, and according to the user's determination from the presented search history, without entering a search keyword, the constant or formula may be displayed. good.

Further, in the embodiment, the electronic device 200 transmits constant or formula data to the computer 100 that has transmitted the formula. On the other hand, the processor 201 of the electronic device 200 may transmit constant or formula data to other computers 100 than the computer 100 that has transmitted the formula. The processor 201 may send constant or formula data to multiple calculators 100 .

Further, each process according to the above-described embodiment can also be stored as a program that can be executed by the processor 201 (or the processor 101) that is a computer. In addition, it can be distributed by being stored in a storage medium of an external storage device such as a magnetic disk, an optical disk, or a semiconductor memory. Then, the processor 201 (or processor 101) or the like reads the program stored in the storage medium of the external storage device, and the operation is controlled by the read program, thereby executing the above-described processing.
