[0045] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in this specification and the accompanying drawings, components having substantially the same functional configuration are denoted by the same reference numerals to omit repeated descriptions.

[0046] <1. Example of structure>

[0047] (1) Example of system structure

[0048] FIG1 is a diagram for explaining a configuration example of a system 1 according to an embodiment. As shown in FIG1 , the system 1 includes an attraction device 100 and a terminal device 200 .

[0049] Suction device 100 is a device that generates a substance to be inhaled by the user. The following description assumes that the substance generated by suction device 100 is an aerosol. Alternatively, the substance generated by suction device 100 may be a gas. Suction device 100 uses a rod-shaped substrate 150 to generate aerosol. Rod-shaped substrate 150 is an example of a substrate containing an aerosol source. Suction device 100 is an example of an aerosol generating device that generates aerosol by heating the aerosol source contained in the substrate.

[0050] Terminal device 200 is an information processing device that performs various information processing related to attraction device 100. Terminal device 200 is used by the user of attraction device 100. Terminal device 200 can also be any device, such as a smartphone, tablet, wearable device, or personal computer (PC). Alternatively, terminal device 200 can be a charger that charges attraction device 100.

[0051] The terminal device 200 is used to change the settings of the attraction device 100 . For example, the terminal device 200 receives a user operation for changing the settings of the attraction device 100 and changes the settings of the attraction device 100 .

[0052] (2) Structure of the suction device 100

[0053] FIG2 is a schematic diagram schematically illustrating an example configuration of a suction device 100 according to this embodiment. As shown in FIG2 , the suction device 100 includes a power supply unit 111, a sensor unit 112, a notification unit 113, a storage unit 114, a communication unit 115, a control unit 116, a heating unit 121, a holding unit 140, and a heat insulating unit 144.

[0054] The power supply unit 111 stores electric power and supplies electric power to the components of the suction device 100 based on the control of the control unit 114. The power supply unit 111 can be composed of a rechargeable battery such as a lithium-ion secondary battery, for example.

[0055] The sensor unit 112 acquires various information related to the suction device 100. For example, the sensor unit 112 may be a pressure sensor such as a condenser microphone, a flow sensor, or a temperature sensor, and acquires values ​​associated with the user's suction. For another example, the sensor unit 112 may be an input device such as a button or switch that receives information from the user.

[0056] The notification unit 113 notifies the user of information and is configured by, for example, a light emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates.

[0057] The storage unit 114 stores various information used for the operation of the suction device 1. The storage unit 114 is composed of a non-volatile storage medium such as a flash memory, for example.

[0058] Communication unit 115 is a communication interface capable of communicating in accordance with any wired or wireless communication standard. Examples of such communication standards include Wi-Fi (registered trademark), Bluetooth (registered trademark), NFC (Near Field Communication), and LPWA (Low Power Wide Area).

[0059] The control unit 116 functions as a processing unit and a control unit, and controls the entire operation of the suction device 100 according to various programs. The control unit 116 is implemented by an electronic circuit such as a CPU (Central Processing Unit) or a microprocessor.

[0060] The holding portion 140 has an internal space 141, which houses a portion of the rod-shaped substrate 150 and holds the rod-shaped substrate 150. The holding portion 140 has an opening 142 that connects the internal space 141 to the outside, and holds the rod-shaped substrate 150 inserted into the internal space 141 through the opening 142. For example, the holding portion 140 is a cylindrical body having the opening 142 and a bottom 143 as its bottom surface, defining a columnar internal space 141. An air flow path that supplies air to the internal space 141 is connected to the holding portion 140. The air inlet, or air inlet hole, of the air flow path is, for example, located on a side surface of the suction device 100. The air outlet, or air outlet hole, of the air flow path to the internal space 141 is, for example, located on the bottom 143.

[0061] The rod-shaped substrate 150 includes a substrate portion 151 and a mouthpiece 152. The substrate portion 151 includes an aerosol source. Examples of the aerosol source include polyols such as glycerin and propylene glycol, and liquids such as water. The aerosol source may also include flavor components derived from or not derived from tobacco. If the suction device 100 is a medical inhaler such as a nebulizer, the aerosol source may also include a pharmaceutical agent. Furthermore, in this exemplary configuration, the aerosol source is not limited to liquids and may also be a solid. When the rod-shaped substrate 150 is held in the holder 140, at least a portion of the substrate portion 151 is contained within the internal space 141, while at least a portion of the mouthpiece 152 protrudes from the opening 142. When a user holds the mouthpiece 152 protruding from the opening 142 and inhales, air flows into the internal space 141 via an air flow path (not shown), and together with the aerosol generated from the substrate portion 151, reaches the user's mouth.

[0062] The heating unit 121 heats the aerosol source, thereby atomizing the aerosol source and generating an aerosol. In the example shown in FIG2 , the heating unit 121 is configured in a film shape and is arranged to cover the outer periphery of the retaining unit 140. Furthermore, when the heating unit 121 generates heat, the substrate portion 151 of the rod-shaped substrate 150 is heated from the outer periphery, and an aerosol is generated. The heating unit 121 generates heat when it is powered by the power supply unit 111. As an example, power may be supplied when the sensor unit 112 detects that the user has started suctioning and / or that specified information has been input. Furthermore, power supply may be stopped when the sensor unit 112 detects that the user has stopped suctioning and / or that specified information has been input.

[0063] The heat insulating portion 144 prevents heat conduction from the heating portion 121 to other components. For example, the heat insulating portion 144 is made of a vacuum insulation material or an aerogel insulation material.

[0064] The above describes an example of the structure of the suction device 100. Of course, the structure of the suction device 100 is not limited to the above, and various structures such as the following examples can be adopted.

[0065] As one example, the heating portion 121 may be configured as a blade and arranged to protrude from the bottom 143 of the holder 140 into the interior space 141. In this case, the blade-shaped heating portion 121 is inserted into the base portion 151 of the rod-shaped substrate 150, heating the base portion 151 of the rod-shaped substrate 150 from within. As another example, the heating portion 121 may be arranged to cover the bottom 143 of the holder 140. Furthermore, the heating portion 121 may be configured as a combination of two or more of a first heating portion covering the outer periphery of the holder 140, a second blade-shaped heating portion, and a third heating portion covering the bottom 143 of the holder 140.

[0066] As another example, the holding portion 140 may include an opening and closing mechanism such as a hinge that opens and closes a portion of the outer shell that defines the internal space 141. Furthermore, the holding portion 140 may clamp the rod-shaped substrate 150 inserted into the internal space 141 by opening and closing the outer shell. In this case, the heating portion 121 may be provided at this clamping location within the holding portion 140, pressing the rod-shaped substrate 150 while heating it.

[0067] Furthermore, the method for atomizing the aerosol source is not limited to heating by the heating unit 121. For example, the aerosol source can also be atomized by induction heating. In this case, the suction device 100 includes at least an electromagnetic induction source, such as a coil that generates a magnetic field, in place of the heating unit 121. The susceptor that generates heat through induction heating can be provided in the suction device 100 or incorporated into the rod-shaped substrate 150.

[0068] Furthermore, the suction device 100 generates aerosol to be inhaled by the user by cooperating with the rod-shaped substrate 150. Therefore, the combination of the suction device 100 and the rod-shaped substrate 150 can also be considered as an aerosol generating system.

[0069] (3) Example of terminal device configuration

[0070] 3 is a block diagram showing a configuration example of a terminal device 200 according to this embodiment. As shown in FIG3 , the terminal device 200 includes an input unit 210 , an output unit 220 , a detection unit 230 , a communication unit 240 , a storage unit 250 , and a control unit 260 .

[0071] The input unit 210 has the function of accepting input of various information. The input unit 210 may also include an input device for accepting input of information from the user. Examples of input devices include buttons, a keyboard, a touch panel, and a microphone. In addition, the input unit 210 may also include various sensors such as an image sensor.

[0072] The output unit 220 has a function of outputting information. The output unit 220 may also include an output device that outputs information to the user. Examples of the output device include a display device that displays information, a light-emitting device that emits light, a vibration device that vibrates, and a sound output device that outputs sound. An example of a display device is a monitor. An example of a light-emitting device is an LED (Light Emitting Diode). An example of a vibration device is an eccentric motor. An example of a sound output device is a speaker. The output unit 220 notifies the user of information by outputting the information input from the control unit 260.

[0073] Detection unit 230 has the function of detecting information related to terminal device 200. Detection unit 230 can also detect the location information of terminal device 200. For example, detection unit 230 receives GNSS (Global Navigation Satellite System) signals from GNSS satellites (e.g., GPS signals from GPS (Global Positioning System) satellites) to detect location information consisting of the latitude and longitude of the device. Detection unit 230 can also detect the movement of terminal device 200. For example, detection unit 230 includes a gyroscope sensor and an accelerometer to detect angular velocity and acceleration.

[0074] Communication unit 240 is a communication interface for transmitting and receiving information between terminal device 200 and other devices. Communication unit 240 performs communication in accordance with any communication standard, whether wired or wireless. Examples of such communication standards include USB (Universal Serial Bus), Wi-Fi (registered trademark), Bluetooth (registered trademark), NFC (Near Field Communication), and LPWA (Low Power Wide Area).

[0075] The storage unit 250 stores various information and is composed of a non-volatile storage medium such as a flash memory.

[0076] The control unit 260 functions as a processing unit or control device, controlling all operations within the terminal device 200 according to various programs. The control unit 260 is implemented, for example, by an electronic circuit such as a CPU (Central Processing Unit) or a microprocessor. Furthermore, the control unit 260 may include a ROM (Read Only Memory) to store programs and computational parameters, and a RAM (Random Access Memory) to temporarily store parameters that may be changed. The terminal device 200 executes various processes under the control of the control unit 260. The processing of information input by the input unit 210, the output of information by the output unit 220, the detection of information by the detection unit 230, the transmission and reception of information by the communication unit 240, and the storage and reading of information by the storage unit 250 are examples of processes controlled by the control unit 260. Other processes executed by the terminal device 200, such as the input of information to various components and the processing of information output from these components, are also controlled by the control unit 260.

[0077] Furthermore, the functions of the control unit 260 may be implemented using an application. The application may be pre-installed or downloaded. Furthermore, the functions of the control unit 260 may be implemented using PWA (Progressive Web Apps).

[0078] <2. Technical Features>

[0079] (1) Heating curve

[0080] The control unit 116 controls the operation of the heating unit 121 based on the heating curve. The operation of the heating unit 121 is controlled by controlling the power supply from the power supply 111 to the heating unit 121. The heating unit 121 heats the rod-shaped substrate 150 using the power supplied from the power supply 111.

[0081] A heating curve is control information used to control the temperature of the heated aerosol source. The heating curve specifies parameters related to the temperature of the heated aerosol source. An example of the temperature of the heated aerosol source is the temperature of the heating unit 121. An example of a parameter related to the temperature of the heated aerosol source is the target value for the temperature of the heating unit 121 (hereinafter referred to as the target temperature). The temperature of the heating unit 121 can also be controlled to vary based on the elapsed time since heating began. In this case, the heating curve includes information specifying the time-series transition of the target temperature. As another example, the heating curve can include parameters specifying the method of supplying power to the heating unit 121 (hereinafter referred to as power supply parameters). Power supply parameters include, for example, the voltage applied to the heating unit 121, the on / off switching of power to the heating unit 121, and the feedback control method to be employed. Turning power on / off to the heating unit 121 can also be considered turning the heating unit 121 on / off.

[0082] The control unit 116 controls the operation of the heating unit 121 so that the temperature of the heating unit 121 (hereinafter also referred to as the actual temperature) fluctuates in a manner consistent with the target temperature specified in the heating profile. Typically, the heating profile is designed so that the user enjoys the best flavor when inhaling the aerosol generated from the rod-shaped substrate 150. Therefore, by controlling the operation of the heating unit 121 based on the heating profile, the user can enjoy the best flavor.

[0083] The temperature control of the heating unit 121 can be achieved, for example, by well-known feedback control. Feedback control can be, for example, PID control (Proportional-Integral-Differential Controller). The control unit 116 can supply the power from the power supply unit 111 to the heating unit 121 in the form of pulses based on pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, in the feedback control, the control unit 116 can control the temperature of the heating unit 121 by adjusting the duty cycle or frequency of the power pulses. Alternatively, in the feedback control, the control unit 116 can also perform simple on / off control. For example, the control unit 116 can execute heating by the heating unit 121 before the actual temperature reaches the target temperature, interrupt heating by the heating unit 121 when the actual temperature reaches the target temperature, and resume heating by the heating unit 121 if the actual temperature becomes lower than the target temperature.

[0084] The temperature of the heating unit 121 can be quantified, for example, by measuring or estimating the resistance of the heating unit 121 (more accurately, the heating resistor that constitutes the heating unit 121). This is because the resistance of the heating resistor changes with temperature. The resistance of the heating resistor can be estimated, for example, by measuring the voltage drop across the heating resistor. The voltage drop across the heating resistor can be measured using a voltage sensor that measures the potential difference applied to the heating resistor. In another example, the temperature of the heating unit 121 can be measured using a temperature sensor, such as a thermistor, located near the heating unit 121.

[0085] Hereinafter, the period from the start to the end of the aerosol generation process using rod-shaped substrate 150 is also referred to as the heating period (section). In other words, the heating period is the period during which power to heating unit 121 is controlled based on the heating profile. The start time (start period) of the heating period is the timing at which heating based on the heating profile begins. The end time (end period) of the heating period is the timing at which a sufficient amount of aerosol is no longer generated. The heating period consists of the first half, a preliminary heating period, and the second half, a puffable period. The puffable period is the period during which a sufficient amount of aerosol is assumed to be generated. The preliminary heating period is the period from the start of heating to the start of the puffable period. The heating performed during the preliminary heating period is also referred to as preliminary heating.

[0086] The notification unit 113 may also notify the user of information indicating the timing of the end of preheating. For example, the notification unit 113 may notify the user of the end of preheating before the end of preheating, or notify the user of the end of preheating at the time of the end of preheating. This notification to the user may be provided, for example, by lighting an LED or vibrating. The user can use this notification as a reference to take a puff from the moment preheating ends.

[0087] Similarly, notification unit 113 may also notify the user of information indicating the timing of the end of the puffable period. For example, notification unit 113 may notify the user of information indicating the end of the puffable period before the end of the puffable period, or notify the user of information indicating the end of the puffable period at the timing of the end of the puffable period. Notification to the user may be provided, for example, by lighting an LED or vibrating. The user can refer to this notification and continue puffing until the end of the puffable period.

[0088] An example of a heating curve will be described with reference to Figure 4. Figure 4 is a graph schematically illustrating an example of a heating curve. The horizontal axis of Figure 20 represents time. The vertical axis of Figure 20 represents temperature. Line 21 shows the time-series transition of the target temperature. As shown in Figure 4, the target temperature rises rapidly to around 300°C after heating begins, then drops to around 230°C and remains maintained until the end. During this period of temperature drop, power to the heating unit 121 is interrupted, and heating is turned off. On the horizontal axis, the timings for the first to sixteenth puffs (hereinafter referred to as puff timings) are shown as #1 to #16. Puff timings can also be pre-set. In the example shown in Figure 4, the period up to the first puff timing is the preparatory heating period, and 16 puff timings are set during the subsequent puffable period.

[0089] (2) Customization of heating curve

[0090] The terminal device 200 (e.g., the control unit 260) controls the customization process. This process customizes (i.e., modifies) the heating curve used by the suction device 100. The user repeatedly customizes the heating curve and tries out the customized heating curve to confirm the taste. The terminal device 200 repeatedly executes the customization process until a heating curve that achieves the user's desired taste is generated. By repeatedly performing the customization process, the heating curve can gradually approach the ideal heating curve that achieves the user's desired taste.

[0091] The customization process includes the terminal device 200 accepting target temperature settings from the user. In particular, the terminal device 200 accepts target temperature settings for each puff timing. The terminal device 200 generates a changed heating curve by changing the target temperature of the heating curve before the change based on the user's settings.

[0092] Customization processing involves the terminal device 200 accepting settings for a taste evaluation from the user. Specifically, the terminal device 200 accepts settings for evaluating the aerosol generated based on a heating curve that reflects the user-set target temperature. This allows the user to evaluate how their customizations affect the taste.

[0093] The following describes a configuration in which the terminal device 200 accepts settings for a user's taste evaluation during the heating period, that is, while the suction device 100 is performing heating based on a heating curve. In this case, the user takes a puff each time the puff timing arrives and sets a taste evaluation on the terminal device 200. While the customization process is being executed, the terminal device 200 may also output information indicating that the puff timing has arrived (equivalent to the first information) each time the puff timing arrives. For example, the terminal device 200 may vibrate each time the puff timing arrives. With this configuration, the user can take a puff triggered by the vibration and set a taste evaluation on the terminal device 200. Alternatively, the terminal device 200 may cause the suction device 100 to output information indicating that the puff timing has arrived.

[0094] The order of accepting the target temperature setting and the evaluation setting during the customization process is arbitrary. In the following, as an example, it is assumed that the terminal device 200 first accepts the setting of the evaluation for the aerosol generated based on the heating curve generated in the previous customization process, and then accepts the setting of the target temperature.

[0095] The customization process involves the terminal device 200 generating a customized display image for the heating curve and displaying the generated display image. The customized display image for the heating curve displays a mark indicating the target temperature included in the heating curve and a mark indicating the evaluation of the aerosol generated by the suction device 100 heating the rod-shaped substrate 150 based on the heating curve. The user sets the target temperature or evaluation using the customized display image for the heating curve as a reference. Examples of the customized display image for the heating curve include an evaluation screen for setting a taste evaluation and a design screen for setting a target temperature. Alternatively, the terminal device 200 may display these screens on a touch panel that serves as both the input unit 210 and the output unit 220. In this case, the user can set the desired target temperature or evaluation on the terminal device 200 by touching various UI (User Interface) elements on the displayed screen. An example of the evaluation and design screens is described below with reference to Figures 5 to 7.

[0096] -Evaluation screen

[0097] FIG5 illustrates an example of an evaluation screen displayed during the Nth customization process. Note that N is an integer greater than or equal to 2. The terminal device 200 receives settings for evaluating aerosol generated based on a heating curve generated during the N-1th customization process (i.e., the previous customization process) on the evaluation screen 300 displayed during the Nth (i.e., current) customization process.

[0098] As shown in FIG5 , evaluation screen 300 includes a design information display field 30, a progress display field 60, and an evaluation setting field 70. Evaluation screen 300, as shown in FIG5 , is displayed when the sixth puff timing of a total of 16 puffs has arrived, i.e., when the taste evaluation is set for the sixth puff timing. The user can set the taste evaluation for the sixth puff on evaluation screen 300.

[0099] The design information display column 30 displays information used for heating curve design. Specifically, it displays a mark indicating the taste evaluation and a mark indicating the target temperature. Numbers #1 to #16, arranged from left to right at the top of the design information display column 30, represent the timings of the first through sixteenth puffs. Furthermore, along the vertical axis extending from the numbers #1 to #16, circular icons 42, 44, and 46, representing the taste evaluation at each puff timing, and a diamond-shaped icon 52, representing the target temperature, are displayed. The design information display column 30 includes the evaluation display column 40 and the temperature display column 50.

[0100] Evaluation display field 40 displays the taste evaluation set for each puff timing. Evaluation display field 40 includes a strength evaluation field 41, a puff quantity evaluation field 43, and a flavor preference evaluation field 45. Strength evaluation field 41 includes an icon 42 indicating the strength evaluation. Puff quantity evaluation field 43 includes an icon 44 indicating the puff quantity evaluation. Flavor preference evaluation field 45 includes an icon 46 indicating the flavor preference evaluation. The icon representing the flavor evaluation set for each puff timing among these icons 42, 44, and 46 may be identified by appending a number indicating the number of puffs to the end of the symbol. For example, the evaluation of strength, puff quantity, and flavor preference set for the first puff timing are indicated by icons 42-1, 44-1, and 46-1. The display of evaluations based on the icons 42 , 44 , and 46 in the evaluation display field 40 will be described in detail later.

[0101] Temperature display field 50 displays the target temperature for each puff timing. Within temperature display field 50, the target temperature is indicated by the positional relationship between icon 52, which represents a reference line 51 and the target temperature. The icon representing the target temperature for each puff timing can be identified within icons 52 by appending a number indicating the puff timing. For example, the target temperature for the first puff timing is indicated by icon 52-1.

[0102] Baseline 51 corresponds to a default temperature (hereinafter referred to as the base temperature). Scale marks above baseline 51 indicate temperatures higher than the base temperature, while scale marks below baseline 51 indicate temperatures lower than the base temperature. For example, one scale mark above baseline 51 may correspond to a base temperature of +15°C, and two scale marks above baseline 51 may correspond to a base temperature of +30°C. Alternatively, one scale mark below baseline 51 may correspond to a base temperature of -15°C, and two scale marks below baseline 51 may correspond to a base temperature of -30°C. In the example shown in FIG5 , the target temperature for the first puff timing, indicated by icon 52-1, is the base temperature +15°C. Furthermore, the target temperature for the seventh puff timing, indicated by icon 52-7, is the base temperature -15°C. The base temperature may be common to all puff timings or may vary for each puff timing.

[0103] The progress display column 60 shows the progress of the heating period. It includes a bar display column 61 and a score display column 62. The bar display column 61 displays the progress rate of the heating period in the form of a progress bar. The entire length of the bar display column 61 corresponds to the puffable period, and the bar extends from left to right as time passes. The progress of the heating period is indicated by the relationship between the position of the right end of the extended bar of the bar display column 61 and the vertical axis extending from the numbers #1 to #16, representing the puff timings displayed in the design information display column 30. In the example shown in FIG5 , the right end of the bar of the bar display column 61 reaches the vertical axis extending from #6, indicating that the heating period has progressed to the sixth puff timing. The score display column 62 displays the progress rate of the heating period in the form of a score. In the example shown in FIG5 , the score display column 62 indicates that the sixth puff timing has arrived, out of a total of 16 puff timings.

[0104] Furthermore, the suction device 100 may transmit information indicating the start of heating to the terminal device 200 upon starting heating. Furthermore, the terminal device 200 may determine the progress of the heating period and the arrival of the puff timing based on the time elapsed since the suction device 100 received the information indicating the start of heating. In the heating curve, the arrival time of each of multiple puff timings may be specified as the elapsed time since the start of heating.

[0105] Evaluation setting field 70 is a field for accepting settings for evaluating the taste of food. As shown in FIG5 , evaluation setting field 70 includes a setting field 71 for evaluating the strength of the food, a setting field 73 for evaluating the amount of smoke produced, and a setting field 75 for evaluating taste preference. Based on user operations in evaluation setting field 70 , terminal device 200 accepts settings for evaluations related to the three evaluation items of strength, amount of smoke produced, and taste preference.

[0106] The momentum evaluation setting column 71 includes buttons 71A through 71C, which are first UI elements for setting the momentum evaluation. Terminal device 200 accepts settings for a strong momentum evaluation when button 71A is selected, a moderate momentum evaluation when button 71B is selected, and a weak momentum evaluation when button 71C is selected. Icons 72A indicating strong momentum are provided on button 71A, 72B indicating moderate momentum are provided on button 71B, and 72C indicating weak momentum are provided on button 71C.

[0107] The smoke quantity evaluation setting field 73 includes buttons 73A through 73C, which are the first UI elements for setting the smoke quantity evaluation. When button 73A is selected, the terminal device 200 accepts settings for a large smoke quantity evaluation; when button 73B is selected, it accepts settings for a moderate smoke quantity evaluation; and when button 73C is selected, it accepts settings for a small smoke quantity evaluation. Button 73A is provided with an icon 74A indicating a large smoke quantity; button 73B is provided with an icon 74B indicating a moderate smoke quantity; and button 73C is provided with an icon 74C indicating a small smoke quantity.

[0108] The taste preference evaluation setting field 75 includes buttons 75A and 75B, which are first UI elements for setting a taste preference evaluation. When button 75A is selected, the terminal device 200 accepts a setting for a favorite taste evaluation, while when button 75B is selected, the terminal device 200 accepts a setting for a disliked taste evaluation. An icon 76A indicating a favorite taste is provided on button 75A, while an icon 76B indicating a disliked taste is provided on button 75B.

[0109] Terminal device 200 accepts settings for a taste evaluation for each of multiple puff timings. For example, each time a puff timing arrives, terminal device 200 accepts a taste evaluation for that puff timing. In the example shown in Figure 5 , buttons 71B, 73B, and 75A are selected as the taste evaluation for the sixth puff timing. In other words, the user has set evaluations such as moderate strength, moderate smoke volume, and a favorite flavor. As shown in Figure 5 , buttons 71B, 73B, and 75A selected by the user can be displayed differently from the other buttons, such as by being highlighted.

[0110] Icons 72 (72A-72C), 74 (74A-74C), and 76 (76A and 76B) displayed in the evaluation setting column 70 correspond to icons 42, 44, and 46 displayed in the evaluation display column 40. Specifically, icons 72 and 42 corresponding to evaluations of strong, moderate, and weak strength are displayed with a dotted circle, a thick circle, and a thin circle, respectively. Furthermore, icons 74 and 44 corresponding to evaluations of large, moderate, and small amounts of smoke are displayed with a dotted circle, a thick circle, and a thin circle, respectively. Furthermore, icons 76 and 46 corresponding to evaluations of a preferred taste and a disliked taste are displayed with a thick circle and a dotted circle, respectively. In the example shown in FIG5 , at the first puff timing (#1), icon 42-1 is a thin-lined circle similar to icon 72C, icon 44-1 is a thin-lined circle similar to icon 74C, and icon 46-1 is a thick-lined circle similar to icon 76A. In other words, the example shown in FIG5 indicates that the evaluation of the first puff timing (#1) is set as weak, with a small amount of smoke, and a pleasant taste.

[0111] Here, the terminal device 200 can display icons 42, 44, and 46 representing the evaluation set in the N-1th customization process, and icons 42, 44, and 46 representing the evaluation set in the Nth customization process. In the N-1th customization process, the evaluation is first set, and then the target temperature is changed. Then, the evaluation is set in the Nth customization process. With this structure, the user can easily understand how the taste evaluation changes with the change in the target temperature in the N-1th customization process.

[0112] In particular, the terminal device 200 displays icons 42, 44, and 46 representing the taste evaluation set in the Nth customization process for puff timings for which a taste evaluation was set in the Nth customization process. On the other hand, for puff timings for which a taste evaluation was not set in the Nth customization process, the terminal device 200 displays icons 42, 44, and 46 representing the taste evaluation set in the N-1th customization process. In the example shown in FIG5 , taste has been set for puff timings up to the sixth puff in the Nth customization process. Therefore, in the evaluation display field 40, icons 42, 44, and 46 (e.g., 42-1, 44-1, and 46-1) representing the evaluation set in the Nth customization process are displayed for puff timings up to the sixth puff. On the other hand, in the evaluation display field 40, icons 42, 44, and 46 (e.g., 42-7, 44-7, and 46-7) representing the evaluation set in the N-1th customization process are displayed for the seventh and subsequent puff timings. This configuration allows the user to easily visually recognize that the evaluation is being updated as the heating period progresses.

[0113] Here, the terminal device 200 may display icons 42, 44, and 46 representing the evaluation set in the N-1th customization process differently from icons 42, 44, and 46 representing the evaluation set in the Nth customization process. In the example shown in FIG5 , icons 42, 44, and 46 (e.g., 42-7, 44-7, and 46-7) representing the taste evaluation for the 7th to 16th puff timings set in the N-1th customization process are displayed as clear circles. Meanwhile, icons 42, 44, and 46 (e.g., 42-1, 44-1, and 46-1) representing the taste evaluation for the 1st to 6th puff timings set in the Nth customization process are displayed as colored circles. This configuration allows the user to easily distinguish between the taste evaluation set in the Nth customization process and the taste evaluation set in the N-1th customization process.

[0114] As another example of displaying in a different manner, in addition to the presence or absence of color as shown in FIG5 , other methods may be used, such as different colors, different color concentrations, different transparency, or different outlines. In particular, it is more preferable that the terminal device 200 display icons 42, 44, and 46 representing the evaluation set in the N-1th customization process with a higher transparency than icons 42, 44, and 46 representing the evaluation set in the Nth customization process. For example, icons 42, 44, and 46 representing the evaluation set in the N-1th customization process are displayed as semi-transparent, while icons 42, 44, and 46 representing the evaluation set in the Nth customization process are displayed as opaque. With this configuration, the user can easily distinguish between the evaluation set in the Nth customization process and the evaluation set in the N-1th customization process.

[0115] If all set taste evaluations meet specified conditions, the terminal device 200 may also output information indicating that the most appropriate heating curve has been generated (equivalent to the second information). An example of a specified condition is a favorable evaluation. For example, if all puff timings are evaluated as having moderate strength, moderate smoke volume, and a preferred flavor, the terminal device 200 may vibrate in a specified pattern. This configuration allows the user to be notified that the customization of the heating curve has been successfully completed.

[0116] -Design screen

[0117] FIG6 illustrates an example of a design screen displayed during the Nth customization process. After the taste evaluation is set on the evaluation screen 300, the terminal device 200 displays the design screen 400. Furthermore, on the design screen 400, the terminal device 200 displays the taste evaluation set during the Nth customization process while accepting the target temperature setting and generating a heating curve reflecting the set target temperature.

[0118] As shown in Figure 6, the design screen 400 includes a design information display column 30 and a temperature setting column 80. The design information display column 30 is described above with reference to Figure 5. The evaluation display column 40 displays the taste evaluation set during the Nth customization process, that is, the taste evaluation set during the heating period that just ended. The temperature setting column 80 is a column for accepting target temperature settings. The temperature setting column 80 includes the evaluation display column 40 and the temperature display column 50. The display contents in these columns are as described above with reference to Figure 5.

[0119] In the temperature setting column 80, the terminal device 200 displays icons 42, 44, and 46 indicating taste evaluations set for a portion of the total puff timings, and an icon 52 indicating the target temperature. In particular, the terminal device 200 displays the portion of the design information display column 30 contained in the focus window 81 in the temperature setting column 80 in an enlarged manner. In the example shown in FIG6 , the focus window 81 includes the 12th through 16th puff timings in the design information display column 30. Therefore, the temperature setting column 80 displays icons 42, 44, and 46 indicating taste evaluations set for the 12th through 16th puff timings (e.g., 42-12, 44-12, and 46-12), and an icon 52 indicating the target temperature (e.g., 52-12). The user can expand the information for any puff timing in the temperature setting column 80 by moving the focus window 81 left or right.

[0120] The terminal device 200 accepts the setting of a target temperature based on a user operation on the temperature setting bar 80. Specifically, the terminal device 200 sets the target temperature based on the position of the icon 52 indicating the target temperature displayed in the temperature setting bar 80. Specifically, the terminal device 200 accepts an operation to move the icon 52 displayed in the temperature setting bar 80 up or down. Furthermore, the terminal device 200 sets the target temperature based on the scale where the moved icon 52 is located. During the Nth customization process, the terminal device 200 can place the icon 52 at the position corresponding to the target temperature set in the N-1th customization process and begin displaying the design screen 400. Therefore, the operation to move the icon 52 displayed in the temperature setting bar 80 up or down corresponds to an operation to change the target temperature set in the N-1th customization process. After accepting the operation to move the icon 52 up or down, the temperature display bar 50 changes to display the target temperature set in the Nth customization process. Furthermore, when a user operation to change the position of the icon 52 is performed in the temperature setting field 80 , the terminal device 200 changes the position of the icon 52 in not only the temperature setting field 80 but also the design information display field 30 .

[0121] The terminal device 200 accepts the setting of target temperatures for each of the multiple puff timings. The terminal device 200 accepts user operations to move the icon 52 indicating the target temperature for each puff timing, displayed in the temperature setting bar 80, upward or downward as the target temperature setting for each puff timing. This configuration allows the user to change the heating temperature during the puff timing, which may significantly affect the taste, in accordance with their intention. Comparing the temperature display bar 50 before customization shown in FIG5 with the temperature display bar 50 after customization shown in FIG6 , it can be seen that in the Nth customization process, the target temperatures for the 15th and 16th puff timings were changed. Specifically, the target temperature for the 15th puff timing was changed from the pre-change baseline temperature + 15°C to the baseline temperature. Furthermore, the target temperature for the 16th puff timing was changed from the pre-change baseline temperature + 15°C to the baseline temperature.

[0122] The terminal device 200 may also display the icon 52 representing the target temperature set in the Nth customization process and the icon 52 representing the target temperature set in the N-1th customization process in different ways. That is, the terminal device 200 may display the icon 52 representing the target temperature changed in the Nth customization process and the icon 52 representing the target temperature that has not been changed since the N-1th customization process in different ways. In the example shown in FIG5 , the icon 52-12 representing the target temperature for the 12th puff timing, which has not been changed since the N-1th customization process, is displayed as a plain diamond. On the other hand, the icons 52-15 and 52-16 representing the target temperatures for the 15th and 16th puff timings, which have been changed in the Nth customization process, are displayed as colored diamonds. This configuration allows the user to easily distinguish between the target temperatures that have been changed in the Nth customization process and the target temperatures that have not been changed. As another example of display in different forms, in addition to the presence or absence of color shown in FIG. 6 , it is also possible to use a difference in color, a difference in color concentration, a difference in transparency, or a difference in outline.

[0123] The temperature setting bar 80 includes an add button 82, a UI element for adding a scale to the temperature display bar (equivalent to a third UI element). When add button 82 is selected, the terminal device 200 expands the range within which the icon 52 representing the target temperature can be moved. For example, when add button 82 is selected, the terminal device 200 adds a scale above the temperature display bar 50, raising the maximum settable temperature. For example, in the example shown in FIG6 , scales are positioned above and below the reference line 51, with the reference temperature ±30°C representing the maximum and minimum settable temperatures. In this state, when add button 82 is selected, the terminal device 200 can also add a third scale above the reference line 51, corresponding to the reference temperature +45°C. As a result, the icon 52 can be moved to the third scale above the reference line 51, allowing the target temperature to be set to +45°C. Of course, when the add button 82 is selected, the terminal device 200 may add a scale mark on the lower side of the temperature display field 50 to lower the minimum settable temperature.

[0124] The design screen 400 includes a previous quantity display button 83, a UI element for displaying the target temperature set in the previous customization process. When the previous quantity display button 83 is selected, the terminal device 200 displays the target temperature before the change in the puff timing, which had the target temperature changed in the Nth customization process, in the temperature setting field 80. Referring to FIG7 , an example of the display when the previous quantity display button 83 is selected in the example shown in FIG6 will be described.

[0125] FIG7 illustrates an example display when the previous amount display button 83 is pressed in the design screen 400 shown in FIG6 . As shown in FIG7 , for the 15th and 16th puff timings, whose target temperatures were changed in the Nth customization process, the terminal device 200 displays not only icons 52 ( 52 - 15 and 52 - 16 ) indicating the changed temperatures, but also icons 52 a ( 52 a - 15 and 52 a - 16 ) indicating the temperatures before the change.

[0126] In this manner, the terminal device 200 may display the icon 52a indicating the target temperature set in the N-1th customization process and the icon 52 indicating the target temperature set in the Nth customization process. With this configuration, the user can easily understand the changes in the target temperature in the Nth customization process.

[0127] In particular, as shown in FIG7 , while the Nth customization process is being executed, the terminal device 200 may display, for a designated puff timing (the first puff timing), an icon 52 a representing the target temperature set in the N-1th customization process, and an icon 52 representing the target temperature set in the Nth customization process. In the example shown in FIG7 , the designated puff timing may be the puff timing whose target temperature was changed in the Nth customization process, or it may be all puff timings. This configuration makes it easy to understand changes in the target temperature during the Nth customization process for the designated puff timing.

[0128] Here, the terminal device 200 may also display the icon 52 indicating the target temperature set in the N-1th customization process and the icon 52a indicating the target temperature set in the N-1th customization process in different ways. In the example shown in FIG7 , the icon 52a indicating the target temperature set in the N-1th customization process is displayed as a dotted diamond. On the other hand, the icon 52 indicating the target temperature set in the Nth customization process is displayed as a solid diamond. According to this structure, the user can easily distinguish the target temperature set in the Nth customization process from the target temperature set in the N-1th customization process.

[0129] As another example of a different display method, in addition to the distinction between the solid line and the dotted line of the contour line shown in FIG7 and the presence or absence of color, a distinction in color, a distinction in color concentration, a distinction in transparency, or a distinction in contour lines may also be used. In particular, it is preferred that the terminal device 200 displays the icon 52a representing the target temperature set in the N-1th customization process with a higher transparency than the icon 52 representing the target temperature set in the Nth customization process. For example, it is preferred that the icon 52a representing the target temperature set in the N-1th customization process is displayed as semi-transparent, and the icon 52 representing the target temperature set in the Nth customization process is displayed as opaque. According to this structure, the user can more easily distinguish the target temperature set in the Nth customization process from the target temperature set in the N-1th customization process.

[0130] Design screen 400 includes a save button 84, a UI element for saving a heating curve reflecting the set target temperature. When save button 84 is selected, terminal device 200 saves the heating curve reflecting the target temperature set on design screen 400. Terminal device 200 may also associate a user-specified name with the heating curve to be saved and save the result.

[0131] The above describes an example of the evaluation screen 300 and the design screen 400. In the case of the first customization process (ie, N=1), default information is displayed as information related to the (N-1)th customization process.

[0132] (3) Processing process

[0133] 8 and 9 , the flow of processing executed in the terminal device 200 according to the present embodiment will be described.

[0134] -Evaluation setting processing

[0135] 8 is a flowchart showing an example of the flow of the evaluation setting process in the N-th customization process executed in the terminal device 200 according to the present embodiment. In the customization process, the evaluation setting process is first executed.

[0136] As shown in FIG8 , control unit 260 first generates evaluation screen 300 and displays it on the touch panel that serves as both input unit 210 and output unit 220 (step S102 ). At this point, control unit 260 displays on evaluation screen 300 icons 42 , 44 , and 46 representing the taste evaluation set in the (N-1)th customization process, and icon 52 representing the target temperature set in the (N-1)th customization process.

[0137] Next, the control unit 260 detects the start of heating based on the heating profile by the suction device 100 (step S104 ). For example, the control unit 260 detects the start of heating based on the heating profile when the communication unit 240 receives information indicating the start of heating from the suction device 100 .

[0138] Then, the control unit 260 updates the display of the evaluation screen 300 according to the elapsed time (step S106 ). For example, the control unit 260 extends the progress bar of the bar display field 61 to the right and increases the number of puff timings that have arrived in the score display field 62 according to the elapsed time.

[0139] Next, control unit 260 determines whether the puff timing has arrived (step S108). For example, control unit 260 determines whether the puff timing has arrived based on the elapsed time since the start of heating. If the puff timing is determined not to have arrived (step S108: NO), the process proceeds to step S114.

[0140] If the puff timing is determined to have arrived (step S108: YES), control unit 260 accepts setting of a taste evaluation (step S110). For example, control unit 260 accepts setting of an evaluation related to strength, smoke volume, and taste preference based on a touch operation on evaluation setting field 70 displayed on evaluation screen 300.

[0141] Next, control unit 260 switches the display of the taste evaluation on evaluation screen 300 (step S112). For example, control unit 260 switches the display of icons 42, 44, and 46 representing the taste evaluation from the display corresponding to the evaluation set in the (N-1)th customization process to the display corresponding to the evaluation set in step S108.

[0142] Next, control unit 260 determines whether the heating period has ended (step S114). For example, control unit 260 determines whether the heating period has ended based on the elapsed time or the number of puffs since the start of heating. If the heating period is determined not to have ended (step S114: No), the process returns to step S106.

[0143] When it is determined that the heating period has ended (step S114 ), the control unit 260 ends the display of the evaluation screen 300 (step S116 ).

[0144] -Target temperature setting process

[0145] 9 is a flowchart showing an example of the flow of the target temperature setting process executed in the terminal device 200 according to the present embodiment. In the customization process, the target temperature setting process is executed following the evaluation setting process.

[0146] As shown in FIG9 , control unit 260 first generates design screen 400 and displays it on the touch panel that serves as both input unit 210 and output unit 220 (step S202 ). At this point, control unit 260 places icon 52 at the position corresponding to the target temperature set in the (N-1)th customization process and displays design screen 400.

[0147] Next, control unit 260 accepts a user operation to set a target temperature (step S204). For example, control unit 260 changes the information displayed in temperature setting field 80 in response to the movement of focus window 81. Furthermore, if icon 52 displayed in temperature setting field 80 is moved vertically, control unit 260 accepts the setting of a target temperature corresponding to the position of icon 52 after the movement.

[0148] Then, the control unit 260 switches the display of the target temperature (step S206). For example, the control unit 260 moves the display position of the icon 52 in the design information display field 30 and the temperature setting field 80 in response to the user operation, and switches the display mode of the moved icon 52 from no color to color.

[0149] Next, control unit 260 determines whether the target temperature setting has been completed (step S208). For example, if save button 84 is selected, control unit 260 determines that the target temperature setting has been completed. If the target temperature setting is determined not to have been completed (step S208: No), the process returns to step S204.

[0150] If the target temperature setting is determined to be complete (step S208: YES), the control unit 260 stores the changed heating curve in the storage unit 250 (step S210). For example, the control unit 260 stores the heating curve reflecting the target temperature set in step S206 in the storage unit 250.

[0151] Next, the control unit 260 controls the communication unit 240 to transmit the modified heating profile to the suction device 100 (step S212). The suction device 100 stores the received heating profile and uses it in the next heating operation. Thus, in the (N+1)th custom process, the suction device 100 performs heating based on the heating profile generated in the (N)th custom process.

[0152] <3. Modifications>

[0153] (1) First Modification

[0154] FIG10 illustrates another example of the evaluation screen displayed during the Nth customization process. Similar to the example shown in FIG5 , the evaluation screen 300 shown in FIG10 includes a design information display field 30, a progress display field 60, and an evaluation setting field 70. The following mainly describes the differences from the example shown in FIG5 .

[0155] As shown in Figure 10, in addition to icons 42, 44, and 46 representing the taste evaluation set in the Nth customization process, the evaluation display field 40 also includes icons 42a, 44a, and 46a representing the taste evaluation set in the N-1th customization process. Furthermore, the icons 42a, 44a, and 46a representing the taste evaluation set for each puff timing may be identified by appending a number indicating the number of puffs to the end of the symbol. For example, in the N-1th customization process, the strength, smoke volume, and taste preference evaluation set for the first puff timing are represented by icons 42a-1, 44a-1, and 46a-1.

[0156] In particular, the terminal device 200 may display icons 42, 44, and 46 indicating the taste evaluation set in the Nth customization process, and icons 42a, 44a, and 46a indicating the taste evaluation set in the N-1th customization process, for puff timings for which a taste evaluation was set in the Nth customization process. Alternatively, the terminal device 200 may display icons 42a, 44a, and 46a indicating the taste evaluation set in the N-1th customization process, for puff timings for which a taste evaluation was not set in the Nth customization process. In the example shown in FIG10 , taste has been set for puff timings up to the sixth puff in the Nth customization process. Therefore, in the evaluation display field 40, icons 42, 44, and 46 (e.g., 42-1, 44-1, and 46-1) representing the evaluation set in the Nth customization process, and icons 42a, 44a, and 46a (e.g., 42-1, 44-1, and 46-1) representing the evaluation set in the N-1th customization process are displayed for puff timings up to the sixth puff. Meanwhile, in the evaluation display field 40, icons 42a, 44a, and 46a (e.g., 42a-7, 44a-7, and 46a-7) representing the evaluation set in the N-1th customization process are displayed for puff timings from the seventh puff onwards. This configuration allows the user to easily visually recognize that the evaluation is being updated as the taste setting progresses.

[0157] Thus, while the Nth customization process is being executed, the terminal device 200 may display the icon 42a representing the taste evaluation set in the N-1th customization process and the icon 42 representing the taste evaluation set in the Nth customization process for a designated puff timing (the second puff timing). In the example shown in FIG10 , the designated puff timing is the puff timing at which the taste evaluation has been set. This configuration makes it easy to understand changes in the taste evaluation during the Nth customization process for the designated puff timing.

[0158] As shown in FIG10 , the temperature setting column 80 may display, for a puff timing whose target temperature was changed in the N-1th customization process, not only an icon 52 indicating the changed temperature (e.g., 52-1) but also an icon 52a indicating the temperature before the change (e.g., 52a-1). Here, icon 52 indicates the target temperature set in the N-1th customization process. Furthermore, icon 52a indicates the target temperature set in the N-2th customization process.

[0159] The terminal device 200 may also display the icon 52 indicating the target temperature set in the N-1th customization process and the icon 52a indicating the target temperature set in the N-2th customization process in different ways. In the example shown in FIG10 , the icon 52a indicating the target temperature set in the N-2th customization process is displayed as a dotted diamond. On the other hand, the icon 52 indicating the target temperature set in the N-1th customization process is displayed as a solid diamond. According to this structure, the user can easily distinguish the target temperature set in the N-1th customization process from the target temperature set in the N-2th customization process.

[0160] As another example of a different display method, in addition to the distinction between the solid line and the dotted line of the contour line shown in FIG10 and the presence or absence of color, a distinction in color, a distinction in color concentration, a distinction in transparency, or a distinction in contour lines may also be used. In particular, it is preferred that the terminal device 200 displays the icon 52a representing the target temperature set in the N-2 customization process with a higher transparency than the icon 52 representing the target temperature set in the N-1 customization process. For example, it is preferred that the icon 52a representing the target temperature set in the N-2 customization process is displayed as semi-transparent, and the icon 52 representing the target temperature set in the N-1 customization process is displayed as opaque. According to this structure, the user can more easily distinguish the target temperature set in the N-1 customization process from the target temperature set in the N-2 customization process.

[0161] (2) Second Modification

[0162] Figures 11-13 illustrate another example of the evaluation screen displayed during the Nth customization process. Evaluation screens 300 (300a, 300b, and 300c) shown in Figures 11-13 show the transition of evaluation screens 300 over time. Specifically, as indicated by the score display field 62, evaluation screen 300a is displayed during the sixth puff, evaluation screen 300b is displayed between the sixth and seventh puffs, and evaluation screen 300c is displayed during the seventh puff. As shown in Figures 11-13, similar to the example shown in Figure 5, evaluation screen 300 includes a design information display field 30, a score display field 62, and an evaluation setting field 70.

[0163] The terminal device 200 displays the progress of the heating period by scrolling the information displayed in the design information display column 30. The terminal device 200 displays information for a portion of the 16 puff timings in the design information display column 30. Furthermore, the terminal device 200 scrolls the information displayed in the design information display column 30 horizontally (an example of a predetermined direction), more specifically, from right to left, as time passes. The terminal device 200 causes the information for the puff timing that has already arrived to disappear from the left end of the design information display column 30 and causes the information for the next puff timing to reappear from the right end of the design information display column 30.

[0164] Specifically, the design information display column 30 includes icons 42, 44, and 46 representing taste evaluations as a plurality of second UI elements corresponding to a plurality of puff timings and a plurality of evaluation items. Furthermore, the design information display column 30 includes an icon 52 representing target temperatures corresponding to a plurality of puff timings. The terminal device 200 arranges icons 42, 44, 46, and 52 corresponding to the same puff timing in a vertical row and scrolls them from right to left at a uniform speed.

[0165] Furthermore, the design information display section 30 includes a frame 63, which serves as a predetermined area for indicating the setting timing of the taste evaluation. Frame 63 is sized to allow scrolling icons 42, 44, 46, and 52 to pass through. Frame 63 is fixedly positioned at the position where scrolling icons 42, 44, 46, and 52 pass through.

[0166] The terminal device 200 arranges multiple icons 42, 44, 46, and 52 corresponding to multiple puff timings horizontally and scrolls them horizontally (more specifically, from right to left). In particular, when a timing (e.g., a puff timing) for which a taste evaluation should be set has arrived, the terminal device 200 scrolls the icons 42, 44, 46, and 52 from right to left as time passes so that the icons 42, 44, 46, and 52 corresponding to the puff timing for which the taste evaluation should be set are positioned within the frame 63. When the scrolled icons 42, 44, 46, and 52 reach the frame 63, the terminal device 200 accepts the setting of the evaluation for the puff timing corresponding to the icons 42, 44, 46, and 52 that reached the frame 63.

[0167] In the example shown in FIG11 , icons 42-6, 44-6, 46-6, and 52-6 are located inside frame 63. Therefore, the terminal device 200 accepts the evaluation of the taste for the sixth puff timing. In the example shown in FIG12 , none of icons 42, 44, 46, and 52 are located inside frame 63. Therefore, the terminal device 200 does not accept the evaluation of the taste. On the other hand, in the example shown in FIG13 , icons 42-7, 44-7, 46-7, and 52-7 are located inside frame 63. Therefore, the terminal device 200 accepts the evaluation of the taste for the seventh puff timing.

[0168] The above-described configuration reduces the amount of information displayed in the design information display field 30 and improves visual clarity. Furthermore, the user can rhythmically set the evaluation of strength, smoke volume, and flavor preference based on the timing of icons 42, 44, 46, and 52 reaching frame 63. This makes the setting of the flavor evaluation more entertaining and enjoyable for the user.

[0169] 11 to 13 illustrate an example in which the second UI element is icons 42, 44, and 46 indicating a taste evaluation. However, the present invention is not limited to this example. The second UI element may be any mark other than icons 42, 44, and 46 indicating a taste evaluation.

[0170] (3) Third Modification

[0171] Figures 14-16 illustrate another example of the evaluation screen displayed during the Nth customization process. The evaluation screens 300 (300d, 300e, and 300f) shown in Figures 14-16 show the transition of evaluation screens 300 over time. These evaluation screens 300d, 300d, and 300f are displayed sequentially during the sixth puff. Similar to the second variation, the evaluation screen 300 of this variation displays the progress of the heating period by scrolling the information displayed in the design information display field 30.

[0172] The design information display bar 30 includes icons 42, 44, and 46 representing taste evaluations as multiple second UI elements corresponding to multiple puff timings and multiple evaluation items. Furthermore, the design information display bar 30 includes an icon 52 representing target temperatures corresponding to multiple puff timings. The terminal device 200 arranges icons 42 and 52 corresponding to the same puff timing in a row vertically, while staggering icons 42, 44, and 46 corresponding to the same puff timing diagonally. Furthermore, the terminal device 200 scrolls icons 42, 44, and 46 and icon 52 from right to left at the same speed. As a result, icons 42, 44, and 46 representing taste evaluations for each evaluation item arrive at the frame 63 in order, with time differences.

[0173] Furthermore, the design information display section 30 includes a frame 63, which serves as a predetermined area for indicating the setting timing of the taste evaluation. Frame 63 is sized to allow scrolling icons 42, 44, 46, and 52 to pass through. Frame 63 is fixedly positioned at the position where scrolling icons 42, 44, 46, and 52 pass through.

[0174] The terminal device 200 arranges multiple icons 42, 44, 46, and 52 corresponding to multiple puff timings horizontally and scrolls them horizontally (more specifically, from right to left). In particular, when a timing (e.g., a puff timing) at which a taste evaluation should be set has arrived, the terminal device 200 scrolls the icons 42, 44, 46, and 52 from right to left as time passes, so that the icons 42, 44, 46, and 52 corresponding to the puff timing at which the taste evaluation should be set are positioned within the frame 63. When the scrolled icons 42, 44, 46, and 52 reach the frame 63, the terminal device 200 accepts the setting of the evaluation for the puff timing corresponding to the icons 42, 44, 46, and 52 that reached the frame 63.

[0175] Here, icons 42, 44, and 46 representing taste evaluations corresponding to different evaluation items at the same puff timing arrive at frame 63 at different times. This is because icons 42, 44, and 46 are scrolled while being arranged diagonally. When a scrolled icon 42, 44, or 46 arrives at frame 63, terminal device 200 accepts settings for the taste evaluation corresponding to the puff timing and evaluation item corresponding to icon 42, 44, or 46 that arrived at frame 63.

[0176] In the example shown in FIG14 , icon 42-6 indicating the evaluation of strength during the sixth puff is located inside frame 63. Therefore, the terminal device 200 accepts the setting of the evaluation of strength during the sixth puff. In the example shown in FIG15 , icon 44-6 indicating the evaluation of the amount of smoke during the sixth puff is located inside frame 63. Therefore, the terminal device 200 accepts the setting of the evaluation of the amount of smoke during the sixth puff. In the example shown in FIG16 , icon 46-6 indicating the evaluation of taste preference during the sixth puff is located inside frame 63. Therefore, the terminal device 200 accepts the setting of the evaluation of taste preference during the sixth puff.

[0177] According to the above structure, the user can set the evaluation of strength, the evaluation of smoke volume, and the evaluation of taste preference in a sequential and rhythmic manner according to the time difference. This can further add entertainment to the setting of the taste evaluation and make the user happy.

[0178] As shown in Figures 14-16 , design screen 400 displays icons 42, 44, or 46 indicating a set taste evaluation, along with buttons 71A-71C, 73A-73C, or 75A and 5B for setting the evaluation, arranged horizontally (an example of a predetermined direction). The evaluation is for the same evaluation item as the icon 42, 44, or 46 indicating the taste evaluation. Specifically, design screen 400 displays a display field 41 for the evaluation of strength and a field 71 for the evaluation of strength horizontally. Design screen 400 displays a display field 43 for the evaluation of smoke volume and a field 73 for the evaluation of smoke volume horizontally. Design screen 400 displays a display field 45 for the evaluation of taste preference and a field 75 for the evaluation of taste preference horizontally. This configuration allows UI elements for each evaluation item to be displayed horizontally, thereby improving visual recognition.
