[0015] (Comparative Example) First, a waveform measuring instrument according to a comparative example will be described. Fig. 11 is a diagram showing the appearance of a waveform measuring instrument 1000 according to a comparative example.

[0016] 11, waveform measuring instrument 1000 according to the comparative example includes various operation buttons and a display unit that displays waveforms, etc. The display unit functions as a touch panel that can be operated by the user's fingers.

[0017] The following describes a general procedure for operating the waveform displayed by waveform measuring instrument 1000. As an example, the following describes a case where the color of the waveform is changed.

[0018] Assume that button 1001 is a button labeled "Display." To change the color of the waveform, the "Display" function must be invoked, so the user presses button 1001.

[0019] When button 1001 is pressed, waveform measurement instrument 1000 displays "Display Group Setting" on the display unit. In the example shown in Fig. 11, reference numeral 1002 indicates "Display Group Setting." "Display Group Setting" displays options such as "Display Group #1," "Display Group #2," ... "Display Group #n."

[0020] For example, when the user touches the "display group #1" portion with his / her finger, a list of waveforms included in the "display group #1" is displayed in window 1003.

[0021] The user touches with his / her finger the waveform whose color he / she wishes to change from the list of waveforms displayed in window 1003. This causes a pop-up window to appear that allows the color of the selected waveform to be changed.

[0022] The user operates the pop-up window to change the color of the waveform displayed by waveform measurement instrument 1000 to a desired color.

[0023] Thus, when performing some operation on the waveform being displayed in waveform measuring instrument 1000 according to the comparative example, the user performs the following steps (1) to (3). (1) Press the button to start the operation you want to perform. (2) Select the waveform to be operated. (3) Perform any desired operation on the waveform, such as changing its color.

[0024] By performing the above-described operations, the user can change the color of the waveform in waveform measurement instrument 1000 according to the comparative example.

[0025] However, in order to perform such an operation, the user must first be aware that waveform measurement instrument 1000 has a function for changing the color of the waveform, and that in order to change the color of the waveform, the user must press button 1001 to call up the "Display" function.

[0026] In other words, if users do not know that there is a function to change the color of a waveform, they will not think about changing the color of the waveform. Even if they know that there is a function to change the color of a waveform, if they do not know that they can change the color of the waveform by pressing the "Display" function, they will not be able to change the color of the waveform easily.

[0027] As described above, in the case of an operating procedure such as that of waveform measuring instrument 1000 according to the comparative example, there are cases in which the user is unable to fully utilize the functions provided by waveform measuring instrument 1000.

[0028] Although changing the color of the waveform has been described as an example, the same applies to other functions.

[0029] (Waveform measuring instrument of the present disclosure) 1 is a diagram showing a schematic configuration of a waveform measuring instrument 10 according to one embodiment. The configuration and functions of the waveform measuring instrument 10 according to one embodiment will be described with reference to FIG.

[0030] The waveform measuring instrument 10 includes a memory unit 11 , an input unit 12 , a display unit 13 , a touch sensor 14 , and a control unit 15 .

[0031] The storage unit 11 may be, for example, a semiconductor memory, a magnetic memory, an optical memory, or the like, but is not limited to these. The storage unit 11 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 11 stores any information used in the operation of the waveform measuring instrument 10. For example, the storage unit 11 may store system programs, application programs, various data, and the like.

[0032] The input unit 12 includes one or more input interfaces that acquire input information based on a user's operation. For example, the input unit 12 may include a button, a rotary knob, and the like.

[0033] The display unit 13 includes one or more output interfaces for displaying information, and may include, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescent) display.

[0034] The display unit 13 can display a plurality of objects, such as, but not limited to, a waveform, a marker, a cursor, and a waveform display area.

[0035] The touch sensor 14 is a sensor that detects that an object has come into contact with the display unit 13. The object that comes into contact with the display unit 13 may be, for example, a user's finger, but is not limited to this. The touch sensor 14 may be any sensor that can detect that an object has come into contact with the display unit 13, and may be, for example, a capacitance type sensor, a resistive film type sensor, or the like.

[0036] When detecting that an object has come into contact with the display unit 13, the touch sensor 14 can detect at which coordinates on the display unit 13 the object has come into contact. The touch sensor 14 outputs the detected information to the control unit 15.

[0037] The touch sensor 14 may be configured integrally with the display unit 13 and function as a touch panel.

[0038] The control unit 15 includes at least one processor, at least one dedicated circuit, or a combination thereof. The processor is a general-purpose processor such as a central processing unit (CPU) or a graphics processing unit (GPU), or a dedicated processor specialized for a specific process. The dedicated circuit is, for example, a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC).

[0039] The control unit 15 reads the programs, data, etc. stored in the storage unit 11 and executes various functions.

[0040] The control unit 15 can control the display of the display unit 13 .

[0041] An example of a procedure for a user to perform an operation on a waveform displayed by waveform measurement instrument 10 will be described with reference to FIGS. 2A to 2C.

[0042] 2A shows how the display unit 13 of the waveform measurement instrument 10 displays two objects, a waveform 101 and a waveform 102. In addition, in FIG. 2A, the user is touching the waveform 102 with his or her index finger.

[0043] Hereinafter, an operation in which the user touches the display unit 13 will also be referred to as a “contact operation.” A contact operation is generally an operation called a “tap” or “touch.”

[0044] When touch sensor 14 detects a touch operation on display unit 13, it outputs information on the coordinates where the touch operation occurred to control unit 15. Based on the information on the coordinates acquired from touch sensor 14, control unit 15 determines that the user has performed a touch operation on waveform 102.

[0045] 2A, the user is not touching the display unit 13 with anything other than the index finger. A touch operation by the user in this manner in which other parts of the display unit 13 are not being touched will hereinafter be referred to as a "first touch operation."

[0046] 2B shows a state in which the user continues to touch waveform 102 with his / her index finger and then touches display unit 13 with his / her middle finger. Such an operation in which the user touches another part of display unit 13 while the first touch operation is being continued is hereinafter referred to as a "second touch operation."

[0047] When the touch sensor 14 detects a second touch operation on the display unit 13 while the first touch operation is being continued, the touch sensor 14 outputs to the control unit 15 information on the coordinates where the second touch operation has been performed.

[0048] Fig. 2C shows a state where, after the state shown in Fig. 2B, the user continues to touch waveform 102 with his / her index finger, but removes his / her middle finger from display unit 13. Note that Fig. 2C does not show the user's hand.

[0049] When touch sensor 14 detects that the second contact operation has ended while the first contact operation is continuing, it outputs information indicating that the second contact operation has ended to control unit 15. The end of the second contact operation means that the object that was in contact with display unit 13 during the second contact operation has been removed from display unit 13.

[0050] When control unit 15 acquires information from touch sensor 14 that the second contact operation has ended while the first contact operation is continuing, control unit 15 displays menu screen 103 near the coordinates where the second contact operation was performed, as shown in Fig. 2C. In the example shown in Fig. 2C, menu screen 103 is displayed so that the area where the user's middle finger was touching display unit 13 is the upper left corner of menu screen 103.

[0051] The menu screen 103 includes a list of functions that can be executed on the object that is the target of the first touch operation. In FIG. 2C, the target of the first touch operation is the waveform 102, so the menu screen 103 includes a list of functions that can be executed on the waveform 102.

[0052] The list of functions that menu screen 103 includes depends on the object that is the target of the first touch operation.

[0053] In this way, when the user performs an operation on an object displayed by waveform measurement instrument 10, the user first selects the object with a first touch operation, then performs a second touch operation, and then ends the second touch operation, which then displays a menu screen containing a list of functions that can be performed on the object.

[0054] In this way, after an object is selected, a menu screen containing a list of functions that can be executed on the object is displayed, allowing the user to easily perform a desired operation on the object.

[0055] For example, if a user wants to change the color of a waveform, in the waveform measurement instrument 1000 according to the comparative example, the user will not be able to change the color of the waveform unless he or she knows that the color can be changed by pressing the "Display" button. In contrast, in the waveform measurement instrument 10 according to one embodiment, a function for changing the color is displayed on the menu screen that is displayed when the second touch operation is completed, so the user can easily change the color of the waveform.

[0056] Furthermore, in the waveform measuring instrument 10 according to one embodiment, when the second touch operation is completed, a menu screen including a list of functions that can be executed on the object is displayed. At this time, functions that the user was not aware of may be displayed on the menu screen. This may prompt the user to use a convenient function that the user was not aware of.

[0057] FIG. 3 shows an example of a menu screen when the target of the first touch operation is a waveform.

[0058] 3 shows a state in which the display unit 13 of the waveform measurement instrument 10 displays a waveform 201 as an object. In FIG. 3, a first touch operation is performed at coordinate 202 on the waveform 201. Also, a second touch operation is performed at coordinate 203.

[0059] When the second touch operation is completed, a menu screen 204 is displayed near the coordinates 203.

[0060] In the example shown in FIG. 3, the menu screen 204 displays "Input" and "Color" as functions that can be executed on the waveform 201.

[0061] The user can switch the display of the waveform 201 on and off by operating the section marked "Input." The user can also change the color of the waveform 201 by operating the section marked "Color."

[0062] FIG. 4 shows an example of a menu screen when the target of the first touch operation is a marker.

[0063] 4 shows a state in which display unit 13 of waveform measuring instrument 10 displays waveform 301 and markers 302 to 305 as objects. In Fig. 4, a first touch operation is performed at coordinate 306 on marker 304. Also, a second touch operation is performed at coordinate 307.

[0064] Then, when the second touch operation is completed, a menu screen 308 is displayed near the coordinates 307 .

[0065] In the example shown in FIG. 4, the menu screen 308 displays "Trace" and "Position" as functions that can be executed for the marker 304.

[0066] The user can change which waveform the marker is placed on by manipulating the part marked "Trace." The user can also change the X-axis position of the marker 304 by manipulating the part marked "Position."

[0067] The operation of waveform measuring instrument 10 will be described with reference to the flowchart shown in FIG.

[0068] Step S101: The control unit 15 constantly determines whether the touch sensor 14 has detected a first contact operation on an object displayed on the display unit 13. If the first contact operation has not been detected (No in step S101), the control unit 15 repeats the process of step S101. If the first contact operation has been detected (Yes in step S101), the control unit 15 proceeds to step S102.

[0069] Note that, if a first contact operation is detected in step S101, control unit 15 may change the display mode of the object that is the target of the first contact, and then proceed to step S102. By control unit 15 changing the display mode of the object that is the target of the first contact, the user can easily understand which object is selected. In order to highlight the object that is the target of the first contact, control unit 15 may change the color of the object, make the display of the object darker, or change the background color of the object.

[0070] Step S102: When the control unit 15 detects the first contact operation, it determines whether the touch sensor 14 has detected the end of the first contact operation. If the first contact operation has ended (Yes in step S102), the control unit 15 ends the process and returns to step S101. If the first contact operation has not ended (No in step S102), the control unit 15 proceeds to step S103.

[0071] Step S103: The control unit 15 determines whether the touch sensor 14 has detected a second touch operation on the display unit 13 while the first touch operation is being continued. If the second touch operation is not detected (No in step S103), the control unit 15 returns to step S102. If the second touch operation is detected (Yes in step S103), the control unit 15 proceeds to step S104.

[0072] Step S104: The control unit 15 determines whether or not the coordinates where the second contact operation is being performed have moved, based on the information on the coordinates of the second contact operation acquired from the touch sensor 14. If the coordinates where the second contact operation is being performed have moved (Yes in step S104), the control unit 15 proceeds to step S105. If the coordinates where the second contact operation is being performed have not moved (No in step S104), the control unit 15 proceeds to step S106.

[0073] Step S105: The control unit 15 determines that the operation performed by the user on the display unit 13 is a zoom operation, and performs the zoom operation on the screen displayed on the display unit 13. When the zoom operation ends, the control unit 15 ends the process and returns to step S101.

[0074] Step S106: The control unit 15 determines whether the touch sensor 14 has detected that the second contact operation on the display unit 13 has ended while the first contact operation is continuing. If the second contact operation has not ended (No in step S106), the control unit 15 returns to step S104. If the second contact operation has ended (Yes in step S106), the control unit 15 proceeds to step S107.

[0075] Step S107: The control unit 15 displays a menu screen including a list of functions that can be executed on the object that is the target of the first touch operation near the coordinates where the second touch operation was performed. When the user's processing on the menu screen is completed, the control unit 15 ends the processing and returns to step S101.

[0076] (Menu screen example) With reference to FIGS. 6 to 10, several examples of menu screens that are displayed when the second touch operation is completed will be described.

[0077] Fig. 6 is an example of a display screen displayed on the display unit 13. In the example of the display screen shown in Fig. 6, the display unit 13 displays a waveform display area 401, a waveform display area 402, a waveform 403, a waveform 404, a cursor 405, and a cursor 406 as objects.

[0078] The waveform display area 401 is a rectangular area displaying a waveform whose horizontal axis is time, and the waveform display area 402 is a rectangular area displaying a waveform whose horizontal axis is frequency.

[0079] The horizontal axis of the waveform 403 is time. The waveform 404 is a waveform obtained by performing FFT (Fast Fourier Transform) analysis on the waveform 403.

[0080] Cursors 405 and 406 are used to measure values ​​on the X-axis (time axis) in the waveform display area 401.

[0081] FIG. 7 shows an example of a menu screen that is displayed when the user touches the waveform display area 401 in the first touch operation and then ends the second touch operation.

[0082] Note that even if the user touches within the waveform display area 401, if the user touches the waveform 403, cursor 405, cursor 406, etc., priority is given to the waveform 403, cursor 405, cursor 406, etc. In other words, if the user touches the waveform 403, cursor 405, cursor 406, etc., a menu screen relating to the waveform 403, cursor 405, cursor 406, etc. is displayed.

[0083] The menu screen shown in FIG. 7 includes a list of functions that can be executed for the waveform display area 401.

[0084] "Number of display divisions" is a function for setting the number of areas into which the waveform display area 401 is divided. In the example shown in Fig. 6, the waveform display area 401 is displayed as one area.

[0085] "Grid" is a function for switching whether or not a grid is displayed in the waveform display area 401.

[0086] “Brightness” is a function for setting the brightness of the waveform display area 401.

[0087] "Trace Label" is a function to switch whether or not trace labels are displayed.

[0088] “Display group setting” is a function for setting a waveform group to be displayed in the waveform display area 401 .

[0089] FIG. 8 shows an example of a menu screen that is displayed when the second touch operation ends in a case where the user touches waveform 403 in the first touch operation.

[0090] The menu screen shown in FIG. 8 contains a list of functions that can be performed on the waveform 403.

[0091] "Input" is a function for switching whether or not the waveform 403 is displayed.

[0092] “Color” is a function for setting the color of the waveform 403.

[0093] "Sample rate" is a function for setting the sampling frequency when measuring the waveform 403.

[0094] "Measure Item" is a function that performs various calculations on the waveform 403. When the user touches "Measure Item," a pop-up window appears displaying a list of calculations that can be performed on the waveform 403. The calculations that can be performed on the waveform 403 include, for example, calculating the maximum value, minimum value, and average value.

[0095] “Auto Scale” is a function that causes the entire waveform 403 to be displayed in the waveform display area 401 .

[0096] FIG. 9 shows an example of a menu screen that is displayed when the second touch operation ends in a case where the user touches the waveform 404 in the first touch operation.

[0097] The menu screen shown in FIG. 9 includes a list of functions that can be performed on waveform 404, which is an FFT waveform.

[0098] "Mode" is a function for switching whether or not the waveform 404 is displayed.

[0099] "Type" is a function that switches the type when performing FFT.

[0100] "Sub Type" is a function that switches the subtype when performing FFT.

[0102] “Center” is a function for setting the coordinates of the center of the waveform display area 402 .

[0103] “Sensitivity” is a function for setting the amount of one section of the vertical axis in the waveform display area 402.

[0104] FIG. 10 shows an example of a menu screen that is displayed when the second touch operation ends in a case where the user touches cursor 405 in the first touch operation.

[0105] The menu screen shown in FIG. 10 includes a list of functions that can be performed on the cursor 405 .

[0106] "Trace" is a function for setting the waveform that is the target of the cursor 405.

[0107] "Position" is a function for setting the position of the cursor 405.

[0108] "Cursor jump" is a function for setting where to jump the cursor 405. For example, when a zoom waveform is selected, the cursor 405 jumps to the zoom waveform.

[0109] "How to read cursor value" is a function that sets which data the cursor 405 will read the value from. The waveform 403 displayed by the display unit 13 does not show all the data, but rather the compressed data. "How to read cursor value" allows you to select whether to read from the data before compression or from the data after compression.

[0110] “Brightness” is a function for setting the brightness of the cursor 405 .

[0111] The waveform measuring instrument 10 according to the embodiment described above can provide a user interface that allows a user to fully utilize the functions of the waveform measuring instrument 10. More specifically, when the touch sensor 14 detects a first touch operation on one of a plurality of objects, the touch sensor 14 detects a second touch operation on the display unit 13 while the first touch operation is being continued, and the touch sensor 14 detects that the second touch operation has ended while the first touch operation is being continued, the control unit 15 of the waveform measuring instrument 10 displays a menu screen near the coordinates where the second touch operation was performed, including a list of functions that can be executed on the object that is the target of the first touch operation. In this way, after a user performs a first touch operation on an object such as a waveform, the waveform measuring instrument 10 according to the embodiment displays a menu screen including a list of functions that can be executed on the object that is the target of the first touch operation. This allows the user to easily perform an operation on an object on which the user wishes to perform some operation. Furthermore, because the menu screen includes a list of functions that can be executed on the object that is the target of the first touch operation, it may encourage the user to use a convenient function that the user was not aware of.

[0112] Another example of displaying a menu screen is to display the menu screen by pressing and holding an object. However, the following drawbacks may arise when pressing and holding an object. (1) It takes time for the device to recognize that it is being pressed and held. (2) A normal tap operation may be mistaken for a long press. (3) There is no flexibility in where the menu screen is displayed. In contrast, the waveform measurement instrument 10 according to one embodiment overcomes the drawbacks of long presses as follows. (1) Both the first and second touch operations can be recognized in a short time. (2) The menu screen is not displayed unless the second touch operation is performed, making it less likely to be recognized incorrectly. (3) The second touch operation can be performed at any position, so the menu screen can be displayed at a desired position.

[0113] It will be apparent to those skilled in the art that the present disclosure can be embodied in other specific forms other than the above-described embodiments without departing from the spirit or essential characteristics thereof. Therefore, the foregoing description is illustrative and not limiting. The scope of the disclosure is defined not by the foregoing description but by the appended claims. All modifications within the range of equivalents of any modifications are intended to be encompassed therein.

[0114] For example, the arrangement and number of each component described above are not limited to the above description and the illustrations in the drawings, and may be arbitrarily configured as long as the functions thereof can be realized.

[0115] For example, in the above-described embodiment, the functions executed by the control unit 15 may be executed by several blocks.
