Description

TECHNICAL FIELD

The present disclosure relates to an information processing device, an information processing method, and a program.

BACKGROUND ART

Inhalation devices that generate substances to be inhaled by a user, such as e-cigarettes and nebulizers, are in widespread use. For example, an inhalation device employs an aerosol source for generating an aerosol, and a substrate including a flavor source or the like for imparting a flavor component to the generated aerosol, to generate an aerosol to which the flavor component has been imparted. The user can enjoy the flavor by inhaling the aerosol to which the flavor component has been imparted, generated by the inhalation device. The action by which the user inhales the aerosol is also referred to below as "puffing" or a "puffing action".
Preferences for the flavor tasted during puffing vary for each user. Thus, it is preferred that the temperature at which the aerosol source, which directly influences the flavor, is heated is customizable by the user. The following PTL 1 discloses a technique for a user to customize the temperature at which an aerosol source is heated.

DESCRIPTION OF EMBODIMENTS

Preferred embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that in the specification and the drawings, duplicate descriptions are omitted by using the same reference signs to denote constituent elements having substantially the same functional configuration.
In this description and the drawings, elements having substantially identical functional configurations may also be distinguished by using the same reference sign followed by a different letter of the alphabet. For example, a plurality of elements having a substantially identical functional configuration are distinguished as an inhalation device 100A and an inhalation device 100B as necessary. However, if there is no need to specifically distinguish between each of the plurality of elements having a substantially identical functional configuration, only the same code is assigned. For example, if it is not necessary to particularly distinguish between the inhalation device 100A and the inhalation device 100B, then the inhalation device is merely referred as the inhalation device 100.

<1. Configuration example>

Fig. 1 is a view showing a configuration example of a system 1 according to an embodiment of the present disclosure. As shown in fig. 1, the system 1 includes a plurality of inhalation devices 100 (100A and 100B), a plurality of terminals (200A and 200B), and a server 300.

The inhalation device 100 is an example of an aerosol generating device that generates an aerosol. Alternatively, the substance generated by the inhalation device may be a gas. The inhalation device 100 can accommodate a stick-type substrate 150. The inhalation device 100 generates the aerosol by using the stick-type substrate 150 accommodated therein. The stick-type substrate 150 is an example of a substrate that contributes to generation of an aerosol. The stick-type substrate 150 contains an aerosol source. The inhalation device 100 generates the aerosol by heating the stick-type substrate 150 accommodated therein.

(1) Configuration example of inhalation device

Fig. 2 is a schematic diagram illustrating schematically a configuration example of the inhalation device 100. As illustrated in fig. 2, an inhalation device 100 according to the present configuration example comprises a power source unit 111, a sensor unit 112, a notification unit 113, a memory unit 114, a communication unit 115, a control unit 116, heating units 121, an accommodating portion 140, and a heat insulating portion 144.
The power source unit 111 stores electric power. The power source unit 111 then supplies the electric power to each component of the inhalation device 100 in accordance with control performed by the control unit 116. The power source unit 111 may be configured, for example, by a rechargeable battery such as a lithium ion secondary battery.
The sensor unit 112 acquires various types of information relating to the inhalation device 100. As an example, the sensor unit 112 is configured by a pressure sensor such as a condenser microphone, a flow rate sensor or a temperature sensor, etc., and acquires values associated with inhalation by a user. As another example, the sensor unit 112 is configured by an input device, such as a button or switch, for accepting input of information from the user.
The notification unit 113 notifies the user of information. The notification unit 113 is configured by a light emitting device that emits light, a display device that displays images, a sound output device that outputs sound, or a vibrating device that vibrates, for example.
The memory unit 114 stores various types of information for the operation of the inhalation device 100. The memory unit 114 is configured by a non-volatile storage medium such as a flash memory, for example.
The communication unit 115 is a communication interface capable of performing communication conforming to any wired or wireless communication standard. Examples of communication standards that may be used include standards that employ Wi-Fi (registered trademark), Bluetooth (registered trademark), BLE (Bluetooth Low Energy) (registered trademark), NFC (Near-Field Communication), or LPWA (Low Power Wide Area), for example.
The control unit 116 functions as an arithmetic processing device and a control device, and controls overall operation within the inhalation device 100 in accordance with various programs. The control unit 116 is realized by a CPU (Central Processing Unit) or an electronic circuit such as a microprocessor, for example.
The accommodating portion 140 has an internal space 141, and holds the stick-type substrate 150 while accommodating a portion of the stick-type substrate 150 in the internal space 141. The accommodating portion 140 has an opening 142 allowing the internal space 141 to communicate with the outside, and accommodates the stick-type substrate 150 that has been inserted into the internal space 141 from the opening 142. For example, the accommodating portion 140 is a cylindrical body comprising the opening 142 and a bottom portion 143 serving as a bottom surface, and defines a columnar internal space 141. An air flow path for supplying air to the internal space 141 is connected to the accommodating portion 140. An air inflow hole, which is an inlet for air into the air flow path, is disposed in a side surface of the inhalation device 100, for example. An air outflow hole serving as an outlet for air from the air flow path to the internal space 141 is disposed in the bottom portion 143, for example.
The stick-type substrate 150 comprises a substrate portion 151 and a mouthpiece portion 152. The substrate portion 151 contains an aerosol source. The aerosol source includes a tobacco-derived or non-tobacco-derived flavor component. If the inhalation device 100 is a medical inhaler such as a nebulizer, the aerosol source may include a drug. The aerosol source may, for example, be a liquid such as water or a polyhydric alcohol, for example glycerol or propylene glycol, containing the tobacco-derived or non-tobacco-derived flavor component, or may be a solid including the tobacco-derived or non-tobacco-derived flavor component. In a state in which the stick-type substrate 150 is being held in the accommodating portion 140, at least a portion of the substrate portion 151 is accommodated in the internal space 141, and at least a portion of the mouthpiece portion 152 protrudes from the opening 142. Then, when the user holds the mouthpiece portion 152 protruding from the opening 142 in their mouth and inhales, air flows into the internal space 141 via the air flow path, which is not illustrated in the drawings, and reaches the inside of the user's mouth together with the aerosol generated from the substrate portion 151.
The heating units 121 heat the aerosol source to atomize the aerosol source, thereby generating the aerosol. In the example illustrated in fig. 2, the heating units 121 are configured in a film shape and are disposed so as to cover the outer periphery of the accommodating portion 140. Then, when the heating units 121 generate heat, the substrate portion 151 of the stick-type substrate 150 is heated from the outer periphery, generating the aerosol. The heating unit 121 generates heat when supplied with electricity from the power source unit 111. By way of example, electricity may be supplied when the sensor unit 112 detects that the user has started inhaling and/or that predetermined information has been input. The supply of electricity may then be stopped when the sensor unit 112 detects that the user has finished inhaling and/or that predetermined information has been input.
The heat insulating portion 144 prevents heat transfer from the heating units 121 to other components. For example, the heat insulating portion 144 is configured from a vacuum heat insulating material or an aerogel heat insulating material, or the like.
A configuration example of the inhalation device 100 has been described above. The inhalation device 100 is, of course, not limited to the configuration described above, and may adopt various configurations, such as those illustrated below by way of example.
As one example, the heating units 121 may have a blade-like form and may be arranged so as to protrude into the internal space 141 from the bottom portion 143 of the accommodating portion 140. In that case, the blade-like heating units 121 are inserted into the substrate portion 151 of the stick-type substrate 150 and heat the substrate portion 151 of the stick-type substrate 150 from the inside. As another example, the heating units 121 may be arranged so as to cover the bottom portion 143 of the accommodating portion 140. Furthermore, the heating units 121 may be configured by a combination of two or more from among a first heating unit covering the outer circumference of the accommodating portion 140, a blade-like second heating unit, and a third heating unit covering the bottom portion 143 of the accommodating portion 140.
As another example, the accommodating portion 140 may comprise an opening/closing mechanism such as a hinge for opening/closing part of a casing that forms the internal space 141. By opening/closing the casing, the accommodating portion 140 may then receive and grip the stick-type substrate 150 which has been inserted into the internal space 141. In that case, the heating units 121 may be provided on the part of the accommodating portion 140 gripping the stick-type substrate 150, and may heat the stick-type substrate 150 while pressing the same.
Furthermore, the means for atomizing the aerosol source is not limited to heating provided by the heating units 121. For example, the means for atomizing the aerosol source may be induction heating. In that case, the inhalation device 100 comprises at least an electromagnetic induction source such as a coil for generating a magnetic field, instead of the heating units 121. A susceptor which generates heat by means of induction heating may be provided in the inhalation device 100, or may be contained in the stick-type substrate 150.
It should be noted that the inhalation device 100 collaborates with the stick-type substrate 150 to generate an aerosol to be inhaled by the user. As such, the combination of the inhalation device 100 and the stick-type substrate 150 may be considered as an aerosol-generating system.

<2. Customization of heating profile>

(1) Heating profile

The control unit 116 controls the operation of the heating units 121 based on the heating profile. Control of the operation of the heating units 121 is achieved by controlling the supply of power from the power source unit 111 to the heating units 121. The heating units 121 heat the stick-type substrate 150 using power supplied from the power source unit 111.
The heating profile is control information for controlling the temperature at which the aerosol source is heated. The heating profile defines a parameter relating to a temperature at which the aerosol source is heated. The temperature of the heating units 121 is an example of the temperature at which the aerosol source is heated. A target value of the temperature of the heating units 121 (also referred to below as the "target temperature") is an example of a parameter relating to the temperature at which the aerosol source is heated. The temperature of the heating units 121 may be controlled to change in accordance with the time elapsed from the start of heating. In this case, the heating profile includes information defining a time-series transition of the target temperature. As another example, the heating profile may comprise a parameter (hereinafter also referred to as a power supply parameter) defining how power is supplied to the heating units 121. The power supply parameters include, for example, a voltage applied to the heating units 121, ON/OFF of the power supply to the heating units 121, or a method of feedback control to be employed. ON/OFF of the power supply to the heating units 121 may be considered as ON/OFF of the heating units 121.
The control unit 116 controls the operation of the heating units 121 such that the temperature of the heating units 121 (also referred to below as the "actual temperature") transitions similarly to the target temperature defined in the heating profile. The heating profile is typically designed such that, when the user inhales the aerosol generated from the stick-type substrate 150, the flavor tasted by the user is optimized. Thus, by controlling the operation of the heating units 121 based on the heating profile, the flavor tasted by the user can be optimized.
The temperature control of the heating units 121 can be achieved by known feedback control, for example. The feedback control may be a Proportional-Integral-Differential Controller (PID) control, for example. The control unit 116 may cause power from the power supply unit 111 to be supplied to the heating units 121 in the form of pulses by pulse width modulation (PWM) or pulse frequency modulation (PFM). In that case, the control unit 116 can perform temperature control of the heating units 121 by adjusting the frequency or the duty ratio of the power pulse in feedback control. Alternatively, the control unit 116 may perform simple ON/OFF control in feedback control. For example, the control unit 116 may perform heating by the heating units 121 until the actual temperature reaches the target temperature, interrupt heating by the heating units 121 when the actual temperature reaches the target temperature, and resume heating by the heating units 121 when the actual temperature falls below the target temperature.
The temperature of the heating units 121 can be quantified by measuring or estimating the electrical resistance value of the heating units 121 (a heating resistive element constituting the heating units 121, to be more precise), for example. This is because the electrical resistance of the heating resistive element varies with temperature. The electrical resistance value of the heating resistive element can be estimated by measuring the amount of voltage drop at the heating resistive element, for example. The amount of voltage drop at the heating resistive element can be measured by a voltage sensor measuring a potential difference applied to the heating resistive element. In another example, the temperature of the heating units 121 can be measured by a temperature sensor such as a thermistor installed near the heating units 121.
The period from the start of the process of generating an aerosol using the stick-type substrate 150 to the end is also referred to hereinafter as a heating session. In other words, a heating session is a period of time during which electrical supply to the heating units 121 is controlled on the basis of the heating profile. The beginning of the heating session is the timing at which heating based on the heating profile is started. The end of the heating session is the timing at which a sufficient amount of aerosol is no longer generated. The heating session comprises a first-half preheating period and a second-half puffing-possible period. The puffing-possible period is the period of time during which a sufficient amount of aerosol is expected to be generated. The preheating period is the period from when heating is started until the puffing-possible period is started. Heating performed in the preheating period is also referred to as preheating.
The notification unit 113 may notify the user of information indicative of the timing at which the preheating ends. For example, the notification unit 113 notifies the user of information announcing the end of the preheating period before the preheating period ends, or notifies the user of information indicating that the preheating has ended at the timing at which the preheating has ended. The notification to the user can be by lighting an LED or vibrating, or the like, for example. By referring to such notification, the user is able to take a puff immediately after the end of the preheating.
Similarly, the notification unit 113 may notify the user of information indicative of when the puffing-possible period ends. For example, the notification unit 113 notifies the user of information announcing the end of the puffing-possible period before the puffing-possible period ends, or notifies the user of information indicating that the puffing-possible period has ended at the timing at which the puffing-possible period has ended. The notification to the user can be by lighting an LED or vibrating, or the like, for example. By referring to such notification, the user is able to take a puff until the end of the puffing-possible period.
An example of the heating profile will be described with reference to fig. 5. Fig. 5 is a graph schematically showing an example of a heating profile. The horizontal axis of the graph 20 denotes time. The vertical axis of the graph 20 denotes temperature. The line 21 denotes a time-series transition of the target temperature. As shown in fig. 5, the heating session may include an initial temperature-increase period, an intermediate temperature-reduction period, and a temperature re-increase period in succession. The initial temperature-increase period is a period in which the temperature of the heating units 121 rapidly rises after the start of heating and is kept at a high temperature. The intermediate temperature-reduction period is a period in which the temperature of the heating units 121 drops after the initial temperature-increase period. The temperature re-increase period is a period in which the temperature of the heating units 121 is once again increased after the intermediate temperature-reduction period. In the example shown in fig. 5, the target temperature rapidly increases to around 300°C during the initial temperature-increase period, then drops to around 230°C during the intermediate temperature-reduction period, after which the temperature increases stepwise to around 260°C during the temperature re-increase period. During the intermediate temperature-reduction period, electrical supply to the heating units 121 may be interrupted and heating may be turned OFF. In the example shown in fig. 5, the period from the start of heating to partway through the initial temperature-increase period is the preheating period, and the period from part way through the initial temperature-increase period to the end of the temperature re-increase period is the puffing-enabled period.

(2) Customization processing

The system 1 repeatedly executes customization processing. The customization processing is processing for customizing (or namely, modifying) the heating profile. The system 1 modifies the heating profile in the customization processing to improve the evaluation by the user. Thus, the system 1 can gradually generate a heating profile that can provide an optimal user experience by repeating the customization processing. The customization processing is executed or controlled by each of the inhalation device 100, the terminal device 200, or the server 300.
The customization processing includes at least: the inhalation device 100 generating the aerosol using the heating profile; setting an evaluation period; receiving settings of an evaluation made by the user; modifying the heating profile based on the set evaluation; and setting the modified heating profile in the inhalation device 100. The customization processing may be repeatedly performed until a heating profile as intended by the user is generated. Each process included in the customization processing will be described in detail below.

- Generation of an aerosol based on the heating profile

The inhalation device 100 generates an aerosol by heating the stick-type substrate 150 based on the heating profile. The user inhales the aerosol generated by the inhalation device 100 to confirm the feeling of inhalation. The user can make a plurality of puffs during the heating session.
The timing at which a puff is performed (hereinafter, puff timing) may be set in advance. In this case, the user performs the puffs at a preset puff timing. For example, the terminal device 200 acquires information indicating the progress of heating from the inhalation device 100 and prompts the user to puff at a prescribed timing during the heating session. The information indicating the progress of heating may include an elapsed time from the start of heating, a temperature of the heating unit 121, and the like. The terminal device 200 may obtain, from the inhalation device 100, identification information of the heating profile used by the inhalation device 100, along with or prior to the information indicating the progress of heating. Thus, even if the puff timing is different for each heating profile, it is possible to appropriately determine the arrival of the puff timing. Of course, the puff timing need not be set in advance. In this case, the user freely puffs at any timing. The inhalation device 100 may transmit information for identifying the actual puff timing to the terminal device 200. The information for identifying the puff timing may be information indicating what number of puffs were made during the heating session, or information identifying the puff timing by the time elapsed from the start of heating. The information for identifying the puff timing may be included in the information indicating the progress of heating and transmitted.

- Setting of evaluation period

The terminal device 200 sets a plurality of evaluation periods by dividing the heating session. An evaluation period is a period for evaluation by a user. For example, the terminal device 200 sets the evaluation period on the basis of the identification information of the heating profile used by the inhalation device 100 and the information indicating the progress of heating.
The evaluation period may include a plurality of puff timings. That is, the user may collectively set evaluations for a plurality of puffs. Here, the puff timing may be a preset puff timing or an actual puff timing. According to such a configuration, it is possible to roughly customize the heating profile. As a result, the burden on the user can be reduced as compared with the case where the evaluation is set for each puff.
Of course, the evaluation period may include one puff timing. That is, the user may set the evaluation for each puff. According to such a configuration, it is possible to finely customize the heating profile.
The terminal device 200 may set the evaluation period on the basis of an elapsed time from the start of heating. For example, the terminal device 200 may set a plurality of 30-second evaluation periods by dividing the puffing-possible period every 30 seconds.
The terminal device 200 may set the evaluation period on the basis of the number of puff timings. For example, the terminal device 200 may divide the puffing-possible period for each puff timing to set the evaluation period for each puff timing. According to such a configuration, even if the puff interval of the user is uneven, the evaluation period can be set appropriately.
The terminal device 200 receives settings for evaluation for a plurality of evaluation items. According to such a configuration, the heating profile can be modified based on evaluations from various aspects.
The terminal device 200 may set a plurality of evaluation periods for each of the plurality of evaluation items. Then, the terminal device 200 may receive settings for evaluation for each evaluation item for the aerosol that the user has inhaled in each of a plurality of evaluation periods set for each of the plurality of evaluation items. For example, the terminal device 200 may set an evaluation period for each 30 seconds for evaluation items A to C, and set an evaluation period for each puff for evaluation items D to F. According to such a configuration, the evaluation period can be set flexibly for each evaluation item, and thus it is possible to improve the ease of customization.

- Reception of settings for evaluation

The terminal device 200 receives settings for evaluation for the aerosol that the user has inhaled in each of a plurality of evaluation periods. In particular, the terminal device 200 receives settings for evaluation for each evaluation item for the aerosol that the user has inhaled in evaluation periods set for each evaluation item. The evaluation set by the user is used in order to modify the heating profile. In other words, receiving the settings for evaluation may be interpreted as receiving the settings for a modification instruction for the heating profile (modification value for the target temperature, which is described later).
For example, the terminal device 200 may display, on a touch panel, a UI (user interface) screen (hereinafter also referred to as an evaluation setting screen) for receiving the settings for evaluation, and may receive a touch operation for setting the evaluation during the evaluation period. The evaluation setting screen may be displayed in real time in accordance with the progress of heating. In this case, the user can set the evaluation in real time while puffing. Of course, the evaluation setting screen may be displayed after the heating session ends. In this case, the user can set the evaluation calmly.
An example of the evaluation setting screen will be described with reference to figs. 6 to 8.
Figs. 6 to 8 are views for explaining an example of the evaluation setting screen. A screen transition is shown in the order of an evaluation setting screen 30A shown in fig. 6, an evaluation setting screen 30B shown in fig. 7, and an evaluation setting screen 30C shown in fig. 8. It is also assumed that the heating session includes a puff timing of 15 puffs, and the settings of the evaluation are received in real time in parallel with the progress of heating.
As shown in figs. 6 to 8, the evaluation setting screen 30 (30A to 30C) includes an evaluation setting field 31 and an evaluation setting field 32. The evaluation setting field 31 receives the settings for evaluation for the evaluation items A to C in which an evaluation period including a plurality of puff timings is set. The evaluation setting column 32 receives the settings for evaluation for the evaluation items D to F in which the evaluation period including one puff timing is set, or namely, the evaluation period is set for each puff. By selecting any one of the "+" button, the "OK" button, or the "-" button from a button group 33A for an evaluation item A, the evaluation for the evaluation item A can be set. The same also applies to button groups 33B to 33F for the evaluation items B to F.
As shown in evaluation setting fields 31 and 32 in the evaluation setting screen 30A of fig. 6, the evaluation setting screen 30A is displayed at the timing when the first evaluation period has 20 seconds remaining and the second of the 15 total puffs is taken. As shown in evaluation setting fields 31 and 32 in the evaluation setting screen 30B of fig. 7, the evaluation setting screen 30B is displayed at the timing when the first evaluation period has 30 seconds remaining and the fourth of the 15 total puffs is taken. As shown in evaluation setting fields 31 and 32 in the evaluation setting screen 30C of fig. 8, the evaluation setting screen 30C is displayed at the timing when the third evaluation period has 30 seconds remaining and the seventh of the 15 total puffs is taken.
Evaluation item A may be smoking flavor. Smoking flavor is the sensation that refers to the overall aerosol taste. It is evaluated that the stronger the taste is, the higher the smoking flavor is, and the weaker the taste is, the lower the smoking flavor is. The "+" button in the button group 33A is a button for setting that the smoking flavor is high. The "OK" button in the button group 33A is a button for setting that the smoking flavor is just right. The "-" button in the button group 33A is a button for setting that the smoking flavor is low. The user can set the evaluation of the smoking flavor by selecting any one button among the "+" button, the "OK button", and the "-" button included in the button group 33A.
Evaluation item B may be the amount of smoke. The amount of smoke is the sensation that refers to the amount of aerosol. The greater the amount of aerosol reaching the mouth of the user per puff is, the greater the amount of smoke is evaluated, and the less the amount of aerosol reaching the mouth of the user per puff is, the less the amount of smoke is evaluated. The "+" button in the button group 33B is a button for setting that the amount of smoke is high. The "OK" button in the button group 33B is a button for setting that the amount of smoke is just right. The "-" button in the button group 33B is a button for setting that the amount of smoke is low. The user can set the evaluation of the amount of smoke by selecting any one button among the "+" button, the "OK button", and the "-" button included in the button group 33B.
Evaluation item C may be the tobacco feeling. The tobacco feeling is the sensation that indicates the proximity to the taste of a cigarette. The closer the flavor itself or flavor concentration of the aerosol is to a cigarette, the stronger the tobacco feeling is evaluated. On the other hand, it is evaluated that the more refreshing the flavor of the aerosol is due to a strong flavor such as fruit or mint, the weaker the tobacco feeling is. The "+" button in the button group 33C is a button for setting that the tobacco feeling is strong. The "OK" button in the button group 33C is a button for setting that the tobacco feeling is just right. The "-" button in the button group 33C is a button for setting that the tobacco feeling is weak. The user can set the evaluation of the tobacco feeling by selecting any one button among the "+" button, the "OK button", and the "-" button included in the button group 33C.
Evaluation item D may be the sense of kick. The sense of kick is a feeling that indicates the degree of stimulation to the throat. Typically, a higher content of nicotine in the aerosol is evaluated to have a stronger sense of kick. The "+" button in the button group 33D is a button for setting that the sense of kick is strong. The "OK" button in the button group 33D is a button for setting that the sense of kick is just right. The "-" button in the button group 33D is a button for setting that the sense of kick is weak. The user can set the evaluation of the sense of kick by selecting any one button among the "+" button, the "OK button", and the "-" button included in the button group 33D.
Evaluation item E may be odor. Odor is the sensation that refers to the proximity to the odor of a cigarette. The closer the odor of the aerosol is to the odor of a cigarette, the stronger the odor is evaluated. On the other hand, it is evaluated that the more refreshing the scent of the aerosol is due to a strong scent such as fruit or mint, the weaker the odor is. The "+" button in the button group 33E is a button for setting that the odor is strong. The "OK" button in the button group 33E is a button for setting that the odor is just right. The "-" button in the button group 33E is a button for setting that the odor is weak. The user can set the evaluation of the odor by selecting any one button among the "+" button, the "OK button", and the "-" button included in the button group 33E.
Evaluation item F may be inhalation response. Inhalation response is a sensation that refers to the degree of stimulation to the entire oral cavity. The "+" button in the button group 33F is a button for setting that the inhalation response is strong. The "OK" button in the button group 33F is a button for setting that the inhalation response is just right. The "-" button in the button group 33F is a button for setting that the inhalation response is weak. The user can set the evaluation of the inhalation response by selecting any one button among the "+" button, the "OK button", and the "-" button included in the button group 33F.

- Setting of heating profile after modification

The terminal device 200 sets the heating profile modified on the basis of the evaluation set by the user to the inhalation device 100. For example, the evaluation set by the user is transmitted to the server 300, and the heating profile is modified by the server 300. The terminal device 200 then receives the modified heating profile from the server 300 and transfers the modified heating profile to the inhalation device 100. The inhalation device 100 stores the modified heating profile when receiving the modified heating profile from the terminal device 200. This is expected to improve the evaluation by the user during the next heating.
The server 300 modifies the target temperature corresponding to the evaluation period on the basis of the evaluation of the aerosol inhaled by the user during the evaluation period. For example, the server 300 increases the target temperature in an evaluation period in which low smoking flavor is evaluated, and decreases the target temperature in an evaluation period in which high smoking flavor is evaluated. Such a configuration can modify the heating profile to improve the evaluation by the user.
The server 300 modifies the target temperature defined in the heating profile used by the inhalation device 100 on the basis of a modification value corresponding to the evaluation set by the user. The modification value corresponding to the evaluation can be set for each evaluation item. An example of modification values of the target temperature corresponding to the evaluation of the evaluation items A to F displayed on the evaluation setting screens 30A to 30C shown in figs. 6 to 8 is shown in Table 1 below.
According to the example shown in Table 1 above, the server 300 lowers the target temperature by 30°C if the "+" button for the evaluation item A is selected. This can reduce the next round of smoking flavor, and thus it is expected that the evaluation by the user will be improved. The server 300 raises the target temperature by 30°C if the "-" button for the evaluation item A is selected. This can increase the next round of smoking flavor, and thus it is expected that the evaluation by the user will be improved. On the other hand, the server 300 does not modify the target temperature if the "OK" button for the evaluation target A is selected. This allows the next round of smoking flavor to remain as in the previous round, and thus a favorable evaluation by the user is expected to be maintained. The same also applies to the other evaluation items.
The server 300 calculates a final modification value of the target temperature for each evaluation period by integrating modification values of the target temperature corresponding to evaluations set for the plurality of evaluation items in overlapping evaluation periods (e.g., evaluation periods including the same puff timing). The server 300 then modifies the heating profile by modifying the target temperature for each evaluation period defined in the heating profile on the basis of the final modification value of the target temperature for each evaluation period. A variety of integration methods are conceivable in order to obtain the final modification value. As one example of the integration method, it is conceivable that the average value, median value, modification value at which the absolute value is greatest (i.e., modification value having the greatest modification width), or modification value at which the absolute value is least (i.e., modification value having the smallest modification width) is adopted as the final modification value. As an example, Table 2 shows an example in which a modification value with a maximum absolute value is adopted as a final modification value.

- Repetition of customization processing

Each process included in the customization processing was described in detail above. The system 1 repeatedly performs the customization processing described above until a heating profile as intended by the user is generated. The repetition of the customization processing will be described below with reference to Table 3 below.
In Table 3, P indicates the heating profile, E indicates the evaluation, and the numbers given after P and E indicate the index corresponding to the number of repetitions of the customization processing. According to Table 3 above, in the first customization processing, the heating profile P1 and the evaluation E1 set for the heating profile P1 are input to the server 300 and the heating profile P2 is output. The heating profile P2 is a heating profile in which a modification for improving a part where the evaluation is not good (e.g., a bad evaluation) included in the evaluation E1 is added to the heating profile P1. Such customization processing is repeated while the heating profile generated in the previous customization processing is used as input to the server 300 in the next customization processing. In the 100th customization processing, if the evaluation E100 set in the heating profile P100 is a good evaluation for all puffs, the heating profile P100 input from the server 300 is output as-is as shown in Table 3 above. Then, the repetition of the customization processing is stopped. In this manner, a heating profile P100 as intended by the user is generated.

(3) Processing Flow

Fig. 9 is a sequence chart showing an example of a customization processing flow implemented by the system 1 according to the present embodiment. The sequence involves the inhalation device 100, the terminal device 200, and the server 300.
As shown in fig. 9, the inhalation device 100 first of all starts heating based on the heating profile (step S102). The inhalation device 100 then sends information indicating the start of heating to the terminal device 200 (step S104). The information indicating the start of heating may include a heating profile used by the inhalation device 100.
Next, the terminal device 200 displays the evaluation setting screen (step S106) For example, the terminal device 200 sets the evaluation period on the basis of the heating profile used by the inhalation device 100. Then, the terminal device 200 displays the evaluation setting screen 30 illustrated in fig. 6 to 8 on the basis of the set evaluation period.
The inhalation device 100 then sends information indicating the progress of heating to the terminal device 200 (step S108). The information indicating the progress of heating may include an elapsed time from the start of heating, a temperature of the heating unit 121, and the like.
The terminal device 200 updates the evaluation setting screen when receiving the information indicating the progress of heating (step S110). For example, the terminal device 200 updates the remaining time of the evaluation period in the evaluation setting field 31 and the number of puffs in the evaluation setting field 32, sets the buttons of the button groups 33A to 33F to an unselected state together with the start of the evaluation period, etc.
Next, the terminal device 200 receives settings for evaluation (step S112). For example, the terminal device 200 receives an operation for selecting any one button among the "+" button, the "OK button", and the "-" button included in the button groups 33A to 33F.
The terminal device 200 then determines whether or not the heating session has ended (step S114). If it is determined that the heating session has ended (step S114: NO), the process returns to step S108.
If it is determined that the heating session has ended (step S114: YES), the terminal device 200 transmits the evaluation results and heating profile to the server 300 (step S116). The evaluation results include information for identifying an evaluation period for each evaluation item, and an evaluation set for each evaluation item and evaluation period.
Next, the server 300 modifies the heating profile received from the terminal device 200 on the basis of the evaluation results received from the terminal device 200 (step S118). For example, the server 300 calculates a final modification value of the target temperature for each puff timing by integrating a plurality of modification values of the target temperature corresponding to evaluations set for a plurality of evaluation items for each puff timing, as illustratively indicated in Table 2. Then, the server 300 modifies the heating profile by modifying the target temperature for each puff timing on the basis of the final modification value for each puff timing.
Next, the server 300 transmits the modified heating profile to the terminal device 200 (step S120). When the terminal device 200 receives the modified heating profile from the server 300, the terminal device transfers the received modified heating profile to the inhalation device 100 (step S122).
Then, upon receiving the modified heating profile, the inhalation device 100 stores the received modified heating profile (step S124). Thus, in the next customization processing, the stick-type substrate 150 is heated on the basis of the modified heating profile.

<3. Processing relating to evaluation trend>

Evaluation trends can differ for each user. An evaluation trend is information indicating a degree of divergence between the evaluation by the user and the evaluations by a plurality of other users for the same aerosol. More simply, the evaluation trend of the user is information indicating the degree of divergence of the evaluation by the user from the average evaluation of all users. For example, even with the same aerosol, one user could evaluate the smoking flavor as high, while another user could evaluate the smoking flavor as low. By identifying the evaluation trend of the user, it is possible to more appropriately interpret the evaluation by the user of the aerosol in accordance with the evaluation trend of the user. As a result, for example, customizing the heating profile in accordance with the evaluation trend of the user makes it possible to more quickly arrive at the heating profile as intended by the user. The quality of the user experience can thus be further improved.

(1) Identification of evaluation trend

The system 1 executes processing to identify the evaluation trend of a user. The processing for identifying the evaluation trend of the user is executed or controlled by each of the inhalation device 100, the terminal device 200, or the server 300.
The processing for identifying the evaluation trend of the user includes processing for collecting the evaluation by a user regarding a heating profile to be evaluated, and processing for identifying an evaluation trend of the user on the basis of the collected evaluation by the user. The processing for collecting the evaluation by the user regarding the heating profile to be evaluated includes the inhalation device 100 generating the aerosol using the heating profile to be evaluated, setting an evaluation period, and receiving settings of the evaluation made by the user. The content of these processes included in the processing of collecting the evaluation by the user regarding the heating profile to be evaluated is as described above with respect to the customization processing. The processing for identifying the evaluation trend of the user will be described below on the basis of the collected evaluation by the user.
The server 300 identifies the evaluation trend of the user on the basis of the evaluation by the user set with respect to the aerosol generated by the inhalation device 100 on the basis of the heating profile to be evaluated. The heating profile to be evaluated is a specific heating profile used to identify the evaluation trend of the user. By identifying the evaluation trend of the user, it is possible to more appropriately interpret the evaluation by the user of the aerosol in accordance with the evaluation trend of the user.
As a first method for identifying the evaluation trend of the user, the server 300 may identify the evaluation trend of the user on the basis of the evaluation by the user regarding the heating profile to be evaluated, and the evaluations by a plurality of other users regarding the heating profile to be evaluated. For example, the server 300 accumulates the evaluations by the plurality of other users regarding the heating profile to be evaluated and calculates an average value. The server 300 identifies, as the evaluation trend of the user, the difference between the evaluation by the user regarding the heating profile to be evaluated, and the evaluations by the plurality of other users regarding the heating profile to be evaluated. Note that, as the evaluation, a modification value of the target temperature corresponding to the evaluation may be used. In other words, instead of a discrete evaluation, such as "high (+)", "just right (OK)", and "low (-)", modification values of the target temperature taking continuous values such as "-30°C", "±0°C", and "+30°C" may be used as the evaluation by the user. This makes it possible to appropriately calculate the average of the evaluations and the differences between the evaluations. For example, when the evaluation of the smoking flavor by the user is "high (+)" or namely "-30°C" and the average value of evaluations by a plurality of other users regarding the smoking flavor is "-10°C", the server 300 identifies that the evaluation trend of the user relating to the smoking flavor is "-20°C". In other words, it is identified that the user tends to evaluate the smoking flavor as high. According to such a configuration, it is possible to quantitatively identify the evaluation trend of the user.
As a second method for identifying the evaluation trend of the user, the server 300 may identify the evaluation trend of the user on the basis of the evaluation by the user regarding the heating profile to be evaluated generated on the basis of the evaluation by a plurality of other users. For example, the heating profile to be evaluated may be a heating profile (hereinafter also referred to as the standard heating profile) evaluated as just right with respect to all puff timings and all evaluation items by a large number of users. In this case, the server 300 identifies the evaluation by the user regarding the standard heating profile as the evaluation trend of the user as-is. For example, when the evaluation of the smoking flavor by the user regarding the standard heating profile is "high (+)" or namely "-30°C", the server 300 identifies that the evaluation trend of the user relating to the smoking flavor is "-30°C". This is because the average of the evaluations of smoking flavor by the plurality of other users for the standard heating profile is "just right (OK)", or namely, "±0°C". According to such a configuration, it is possible to easily identify the evaluation trend of the user.
The server 300 may identify the evaluation trend of the user in each of the plurality of evaluation periods on the basis of evaluations respectively set for a plurality of evaluation periods set in a period (i.e., heating session) in which the inhalation device 100 executes processing for generating an aerosol on the basis of a heating profile to be evaluated. For example, if the evaluation period is set for each puff, the server 300 may identify the evaluation trend of the user for each puff. Specifically, when the evaluation of the smoking flavor of the first puff by the user is "high (+)" or namely "-30°C" and the average value of evaluations by a plurality of other users regarding the smoking flavor of the first puff is "-10°C", the server 300 identifies that the evaluation trend of the user relating to the smoking flavor of the first puff is "-20°C". According to such a configuration, it is possible to identify the evaluation trend of the user in more detail. For example, it is possible to identify time-series changes in the evaluation trend, such as where, in the first half of the heating session, the user tends to evaluate the smoking flavor as high, and in the second half of the heating session, the user tends to evaluate the smoking flavor as low.
The server 300 may identify the evaluation trend of the user for each of the plurality of evaluation items on the basis of the evaluation set for each of the plurality of evaluation items. For example, the server 300 may identify the evaluation trend of the user for the smoking flavor on the basis of the evaluation set for the smoking flavor. The same also applies to the other evaluation items. According to such a configuration, it is possible to identify the evaluation trend of the user in more detail. For example, it is possible to identify a difference in evaluation trends for each evaluation item, such as where the user tends to evaluate the smoking flavor as high, while tending to evaluate the amount of smoke as low.
Here, the processing for collecting the evaluation by the user regarding the heating profile to be evaluated may be performed a plurality of times. The evaluation trend of the user may be identified on the basis of a plurality of collected evaluations. In this case, the server 300 identifies the evaluation trend of the user on the basis of a plurality of evaluations acquired when the inhalation device 100 performs, a plurality of times, the processing for generating an aerosol on the basis of the heating profile to be evaluated. For example, if the processing for collecting the evaluation by the user regarding the heating profile to be evaluated is performed three times, the server 300 handles the average value of the evaluations by the user in an amount equivalent to three times for the smoking flavor of the first puff, and identifies the evaluation trend of the user. According to such a configuration, it is possible to prevent excess and deficiency from occurring in the modification of the target temperature due to fluctuations in the evaluation by the user.

A specific example of the first method for identifying the evaluation trend of the user will be described below with reference to Tables 4 to 6. Here, it is assumed that the heating based on the heating profile to be evaluated has been performed three times. Table 4 shows the evaluations for each puff set by the user for evaluation item A, and the average value of three evaluations. Table 5 shows the average value of evaluations for each puff set by a plurality of other users for evaluation item A. The server 300 identifies the evaluation trend of the user shown in Table 6 by calculating the difference between the average value shown in Table 4 and the average value shown in Table 5.

Next, a specific example of the second method for identifying the evaluation trend of the user will be described below with reference to Table 4 above and Table 7 below. Here, it is assumed that heating based on the standard heating profile is performed three times, and the evaluation shown in Table 4 is set. The server 300 identifies the average values shown in Table 4 as-is as the evaluation trend of the user, as shown in Table 7.

An example of a processing flow for identifying the evaluation trend of the user will now be described with reference to fig. 10 and fig. 11.
Fig. 10 is a flow chart for explaining an example of a processing flow according to the first method for identifying an evaluation trend of the user implemented by the server 300 according to the present embodiment.
As shown in fig. 10, first, the server 300 collects the evaluation trend of the user regarding the heating profile to be evaluated, and the evaluations by a plurality of other users regarding the heating profile to be evaluated (step S202).
Next, the server 300 identifies, as the evaluation trend of the user, the difference between a modification value of the target temperature corresponding to the evaluation by the user regarding the heating profile to be evaluated, and an average value of modification values of the target temperature corresponding to the evaluations by a plurality of other users regarding the heating profile to be evaluated (step S204).
Fig. 11 is a flow chart for explaining an example of a processing flow according to the second method for identifying an evaluation trend of the user implemented by the server 300 according to the present embodiment.
As shown in fig. 11, first, the server 300 collects the evaluation by the user for the standard heating profile (step S302).
The server 300 then identifies a modification value of the target temperature corresponding to the evaluation by the user for the standard heating profile as the evaluation trend of the user (step S304).

(2) Modification of heating profile based on evaluation trend

The server 300 modifies the heating profile on the basis of the evaluation by the user set with respect to the aerosol generated by the inhalation device 100 on the basis of the heating profile to be evaluated, and the evaluation trend of the user. Specifically, the server 300 modifies the heating profile on the basis of the evaluation trend of the user in addition to the evaluation by the user when modifying the heating profile on the basis of the evaluation set by the user in the customization processing. According to such a configuration, the heating profile can be modified after more appropriately interpreting the evaluation by the user for the aerosol in accordance with the evaluation trend of the user. Therefore, it becomes possible to reach the heating profile as intended by the user faster.
The server 300 corrects the modification value of the target temperature corresponding to the evaluation by the user for the heating profile on the basis of the evaluation trend of the user, and modifies the heating profile on the basis of the corrected modification value of the target temperature. As an example, the server 300 may correct the modification value corresponding to the evaluation by the user in a direction opposite to the evaluation trend of the user. For example, the server 300 may correct the evaluation of the smoking flavor to a smaller degree if the user tends to evaluate the smoking flavor as high. With such a configuration, it is possible to prevent the target temperature from being modified excessively on the basis of an exaggerated evaluation by the user. As a result, it is possible to prevent situations such as excessive modifications of the target temperature being repeated and not easily reaching the heating profile as intended by the user.
The server 300 may modify the heating profile on the basis of evaluations respectively set for a plurality of evaluation periods set in a period (i.e., heating session) in which the inhalation device 100 executes processing for generating an aerosol on the basis of the heating profile, and an evaluation trend of the user for each evaluation period. Specifically, the server 300 corrects the modification value corresponding to the evaluation for each evaluation period on the basis of the evaluation trend for each evaluation period. Then, the server 300 modifies the target temperature for each evaluation period on the basis of the corrected modification value for each evaluation period. For example, when the evaluation period is set for each puff, the server 300 corrects a modification value corresponding to the evaluation for each puff on the basis of the evaluation trend for each puff, and modifies a target temperature for each puff timing on the basis of the corrected modification value. According to such a configuration, even if the evaluation trend of the user is different for each puff, the heating profile can be appropriately modified.
The server 300 may modify the heating profile on the basis of a plurality of modification values of the target temperature corresponding to a plurality of evaluations set for a plurality of evaluation items, and an evaluation trend of the user for each evaluation item. Specifically, the server 300 corrects the modification value of the target temperature corresponding to the evaluation for each evaluation item on the basis of the evaluation trend for each evaluation item. For example, the server 300 corrects the modification value of the target temperature corresponding to the evaluation set for the smoking flavor on the basis of the evaluation trend of the user for the smoking flavor. The same also applies to the other evaluation items. Then, the server 300 modifies the heating profile on the basis of the corrected modification value of the target temperature for each evaluation item. According to such a configuration, even if the evaluation trend of the user is different for each evaluation item, the heating profile can be appropriately modified.
The server 300 may integrate the corrected modification values of the target temperature for each evaluation item, and may modify the heating profile on the basis of the integrated modification value of the target temperature. Specifically, the server 300 calculates a final modification value of the target temperature for each evaluation period by integrating the corrected modification values of the target temperature for each evaluation item in an overlapping evaluation period. The server 300 then modifies the heating profile by modifying the target temperature for each evaluation period defined in the heating profile on the basis of the final modification value of the target temperature for each evaluation period. The integration method for obtaining the final modification value of the target temperature is as described above with reference to Table 2.

A specific example of correcting the modification value of the target temperature on the basis of the evaluation and evaluation trend of the user for each puff for evaluation item A will be described below with reference to Table 8 below. In the example shown in Table 8 below, the server 300 subtracts the evaluation trend "-10°C" of the user for the first puff from the modification value "-20°C" of the target temperature corresponding to the evaluation "+" set by the user for the first puff, thereby calculating the corrected modification value "-10°C" of the target temperature. This corresponds to correcting the evaluation to a small degree due to the user tending to evaluate the evaluation the evaluation item A as high/strong. The same also applies to the second puff. On the other hand, for the third puff, the server 300 sets the corrected modification value of the target temperature to "±0°C" due to the evaluation by the user being "just right (OK").

Table 8

Table 8. One example of correction method for modification value of target temperature for evaluation item A
	First puff	Second puff	Third puff
Evaluation set by user	+ (-20°C)	+ (-20°C)	OK (±0°C)
Evaluation trend of user	+ (-10°C)	+ (-12°C)	+ (-10°C)	...
Corrected modification value	+ (-10°C)	+ (-8°C)	OK (±0°C)

As shown in Table 8 above, the server 300 may correct the modification value of the target temperature corresponding to a part where the evaluation is not good (e.g., a bad evaluation) included in the evaluation by the user with regard to the heating profile on the basis of the evaluation trend of the user, and may modify the heating profile on the basis of the corrected modification value of the target temperature. Specifically, the server 300 may modify the target temperature of the puff timing that was evaluated as high/strong (+) or low/weak (-). According to such a configuration, it is possible to modify the heating profile to improve the evaluation by the user.
As shown in Table 8 above, the server 300 need not perform a correction based on the evaluation trend of the user for the modification value of the target temperature corresponding to a good evaluation in the evaluation by the user with regard to the heating profile. In particular, the server 300 need not modify the target temperature of the puff timing evaluated as just right (OK). According to such a configuration, it is possible to prevent the evaluation by the user from worsening due to the modification of the heating profile.

The server 300 may modify the heating profile after weighting the evaluation trend. An example of this case will be described with reference to Table 9 below. In the example shown in Table 9 below, the server 300 subtracts the weighted evaluation trend "-5°C", obtained by multiplying the evaluation trend "-10°C" of the user for the first puff by a coefficient "0.5", from the modification value "-20°C" of the target temperature corresponding to the evaluation "+" set by the user for the first puff. The same also applies to the second puff.

Table 9

Table 9. One example of correction method for modification value of target temperature for evaluation item A
	First puff	Second puff	Third puff	...
Evaluation set by user	+ (-20°C)	+ (-20°C)	OK (±0°C)
Evaluation trend of user	+ (-10°C)	+ (-12°C)	(-10°C)
Coefficient	0.5	0.5	0.5	...
Corrected modification value	+ (-15°C)	+ (-14°C)	OK (±0°C)	...

The coefficients shown in Table 9 above correspond to the weightings assigned to the evaluation trends. The server 300 may set coefficients that differ for each evaluation period, and/or for each evaluation item.
An example of a processing flow for modifying the heating profile on the basis of the evaluation trend will now be described with reference to fig. 12.
Fig. 12 is a flow chart for explaining an example of a processing flow for modifying a heating profile on the basis of the evaluation trend implemented by the server 300 according to the present embodiment. The processing described in this flow can be performed in step S118 shown in Fig. 9.
As shown in fig. 12, first, the server 300 corrects the modification value of the target temperature corresponding to the evaluation for each evaluation item and evaluation period on the basis of the evaluation trend of the user for each evaluation item and evaluation period (step S402). For example, the server 300 corrects each of the plurality of modification values of the target temperatures corresponding to the evaluation for each puff timing set for the plurality of evaluation items, on the basis of the evaluation trend of the user for each evaluation item and puff timing.
Then, the server 300 integrates the corrected modification values of the target temperatures for each evaluation period (step S404). For example, the server 300 calculates a final modification value of the target temperature for each puff timing by integrating a plurality of corrected modification values of the target temperatures corresponding to evaluations set for a plurality of evaluation items for each overlapping puff timing.
Then, the server 300 modifies the heating profile on the basis of the final modification value of the target temperature for each evaluation period (step S406). For example, the server 300 modifies the target temperature for each puff timing on the basis of the final modification value of the target temperature for each puff timing.

<4. Supplementary information>

Although preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, the present disclosure is not limited to such examples. It is obvious that a person having an ordinary level of knowledge in the technical field to which the present disclosure belongs could conceive of various modified examples or variations within the scope of the technical concepts set forth in the claims, and these modified examples and variations will naturally be understood to fall within the technical scope of the present disclosure.

(1) First variant example

The server 300 generates a new heating profile (hereinafter also referred to as the modified heating profile) by modifying a heating profile (hereinafter also referred to as the unmodified heating profile) on the basis of the evaluation set by the user. The server 300 may generate the modified heating profile on the basis of a trained generation model to generate the heating profile. The generation model outputs the modified heating profile when the unmodified heating profile and the evaluation set for the unmodified heating profile are input. The generation model may be a model trained by known machine learning techniques, such as SVM (Support Vector Machine) or a neural network.
The server 300 may collect a plurality of teacher data and train the generation model on the basis of the plurality of collected teacher data. The teacher data includes a combination of a first heating profile, an evaluation set for the first heating profile, and a second heating profile to be generated on the basis of the first heating profile and the evaluation set for the first heating profile. That is, the teacher data is a desirable combination of the unmodified heating profile that is input to the generation model and the evaluation set for unmodified heating profile, and the modified heating profile, which is the output from the generation model. By collecting such teacher data, a highly accurate generation model can be trained. Note that the accuracy of the generation model corresponds to the accuracy of the heating profile generated using the generation model.
The server 300 may collect the teacher data in the process of repeating the customization processing. For example, in the example shown in Table 3, the server 300 may collect teacher data including a heating profile P1 as the first heating profile, an evaluation E1, and a heating profile P100 as a second heating profile.
Furthermore, the server 300 may collect teacher data including information indicative of the evaluation trend of the user. According to such a configuration, it is possible to train the generation model in consideration of the evaluation trend of the user. As a result, it is possible to improve the accuracy of the generation model.
As an example, the server 300 may collect the evaluation trend of the user as teacher data. For example, in the example shown in Table 3, the server 300 may collect teacher data including a heating profile P1 as the first heating profile, an evaluation E1, an evaluation trend of the user, and a heating profile P100 as a second heating profile.
As another example, the server 300 may collect, as teacher data, evaluations corrected on the basis of the evaluation trends of the user. For example, in the example shown in Table 3, the server 300 may collect teacher data including a heating profile P1 as the first heating profile, an evaluation E1 corrected on the basis of the evaluation trend of the user, and a heating profile P100 as a second heating profile.

(2) Other variant example

An example was described above in which a modification value corresponding to an evaluation by a user is corrected in the opposite direction of the evaluation trend of the user, but the present disclosure is not limited to this example. The server 300 may correct the modification value corresponding to the evaluation by the user in the same direction as the evaluation trend of the user. For example, when the user tends to evaluate the smoking flavor as high, the server 300 may correct the evaluation of the smoking flavor to be higher. According to such a configuration, it is possible to prevent the modification width of the target temperature from being insufficient on the basis of a modest evaluation by the user. As a result, it is possible to prevent situations such as the target temperature only being modified a small amount each time, and not easily reaching the heating profile as intended by the user.
Each process executed by the terminal device 200 or the server 300, described in the above embodiment, may be executed by any device. As an example, the evaluation period may be set by the server 300. As another example, the heating profile may be modified by the terminal device 200.
The above embodiment includes modifying the target temperature as an example of modifying the heating profile, but the present disclosure is not limited to such an example. The server 300 may modify the parameters relating to the time of the heating profile. Examples of parameters relating to the time of the heating profile include, for example, the time length of the heating session, the initial temperature rise period, the intermediate temperature fall period, and a time length of each of the re-temperature rise periods. In addition, the parameters relating to the time of the heating profile include puff timing.
The embodiment above described an example in which a parameter relating to the temperature at which the aerosol source is heated, as defined in the heating profile, is a target value of the temperature of the heating units 121, but the present disclosure is not limited to such an example. An example of parameters relating to the temperature at which the aerosol source is heated includes a target value of electrical resistance of the heating units 121. Furthermore, when the means for heating the aerosol source is induction heating, a target value such as the temperature of a susceptor or the electrical resistance value of an electromagnetic induction source may be cited as a parameter relating to the temperature at which the aerosol source is heated, as defined in the heating profile.
The embodiment above described an example in which the inhalation device 100 generates the aerosol by heating the stick-type substrate 150, but the present disclosure is not limited to such an example. The inhalation device 100 may equally be configured as what is known as a liquid atomization aerosol-generating device, which generates an aerosol by heating and atomizing a liquid aerosol source. The features of the present disclosure may also be applied to a liquid atomization aerosol-generating device.
As described in the above embodiment, the processes such as setting the evaluation period, receiving settings for evaluation, setting the modified heating profile to the inhalation device 100, etc. are performed by the terminal device 200. Here, the terminal device 200 implementing these processes may also refer to these processes being implemented via a native application installed on the terminal device 200. Furthermore, the terminal device 200 implementing these processes may also refer to these processes being implemented via PWA (progressive web apps) provided for the terminal device 200. As an example, a server 300 may implement these processes via a PWA provided for the terminal device 200.
In the above embodiment, at least a portion of the functional configuration of the inhalation device 100 may be included in other devices. One example of such other devices includes a charger that charges the inhalation device 100. The charger has a mechanism to which the inhalation device 100 can be attached/detached, and can charge the inhalation device 100 or transmit/receive information to/from the inhalation device 100 with the inhalation device 100 connected. As an example, the charger may have a wireless communication function, and may relay transmission and reception of information between the inhalation device 100 and a device such as a smartphone. As another example, the charger may have a memory function and store information received from or to be sent to the inhalation device 100. The combination of the inhalation device 100 and the charger may be considered to be an aerosol generation system. Also, at least a part of the functional configuration of the terminal device 200 described in the above embodiment may be included in another device such as a charger that charges the inhalation device 100.
It should be noted that the series of processes performed by each device described in the present description may be realized by using software, hardware, and any combination of software and hardware. Programs constituting the software are prestored on a recording medium (more specifically, a non-transitory computer-readable storage medium) provided internally or externally to each device, for example. When the programs are then executed, for example, by a computer for controlling each device described in the present description, the programs are read into a RAM and executed by means of a processing circuit such as a CPU. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, or a flash memory, etc. Furthermore, the computer programs may be distributed via a network, for example, without the use of a recording medium. Furthermore, the computer may be an application-specific integrated circuit such as ASIC, a general-purpose processor which executes functions by reading software programs, or a computer on a server used for cloud computing, etc. Furthermore, the series of processes performed by each device described in the present description may be processed in a distributed manner by multiple computers.
Furthermore, the processing described using flowcharts or sequence diagrams in the present description need not necessarily be implemented in the order depicted. Some processing steps may be implemented in parallel. Furthermore, additional processing steps may be employed and some processing steps may be omitted.
