• evaluation results refers to the elapsed time from the start of heating of one stick-type substrate 150 based on the heating profile.
• the terminal device 200 performs various processes to accept evaluations of the smoking taste that contribute to improving the quality of the user experience. The following is a detailed explanation of this point.
• the user's behavior history includes information indicating the second puff timing.
• the second puff timing is the timing at which the user actually performed a puff during a past heating session.
• the terminal device 200 may set a timing that is the same as the second puff timing as the first puff timing.
• the terminal device 200 may set the first puff timing as the same as the second puff timing or shifted by a few seconds. According to this configuration, the user can evaluate the smoking taste while puffing at the usual timing. In other words, the user can set the smoking taste evaluation without changing their usual behavior. Therefore, the burden on the user can be reduced.
• the user's behavior history may include each of the multiple second puff timings in past heating sessions.
• the terminal device 200 may set the average value of the first second puff timing (i.e., elapsed time from the start of heating) in multiple past heating sessions as the first first puff timing in the next heating session. With this configuration, the user can puff at the usual timing.
• the terminal device 200 may set the first puff timing also based on the behavior history of other users. That is, the terminal device 200 may set the first puff timing based on the behavior history of multiple users. For example, the terminal device 200 may set the average value of the second puff timings of multiple users as the first puff timing. With this configuration, the user can puff at the same timing as many other users. Furthermore, it becomes easier to aggregate the evaluation results collected from multiple users.
• the terminal device 200 determines the arrival of the set first puff timing. For example, the inhalation device 100 may transmit information indicating the start of heating to the terminal device 200 when heating based on the heating profile begins. In that case, the terminal device 200 counts the elapsed time from the start of heating as a trigger upon receiving such information and determines the arrival of the first puff timing. The terminal device 200 then controls the process of notifying information indicating the set first puff timing.
• the terminal device 200 may notify information indicating the set first puff timing. Specifically, the terminal device 200 may output an image to the display indicating that the first puff timing will arrive in a few seconds or has arrived, or it may vibrate at the first puff timing. According to this configuration, the user can easily recognize the first puff timing.
• the terminal device 200 may control the inhalation device 100 to notify information indicating the set first puff timing. Specifically, the terminal device 200 may control the inhalation device 100 to emit light from an LED or vibrate at the first puff timing. For example, the terminal device 200 may transmit information instructing the inhalation device 100 to notify the user each time the first puff timing arrives. In that case, the inhalation device 100 emits light from an LED or vibrates each time it receives such information. According to this configuration, the user can easily recognize the first puff timing even in situations where the terminal device 200 is stored in a bag while using the inhalation device 100.
• the terminal device 200 sets multiple evaluation periods within the heating session. In particular, the terminal device 200 sets one evaluation period for each first puff timing. For example, the terminal device 200 sets a predetermined period including the first puff timing or a predetermined period following the first puff timing as the evaluation period. According to this configuration, the user can set the smoking taste evaluation for each puff immediately after puffing in response to the notification of the first puff timing. Therefore, the user can set the smoking taste evaluation for each puff before the memory fades. Additionally, compared to setting the smoking taste evaluation after the heating session has ended, the user's burden can be reduced.
• the relationship between the first puff timing and the evaluation period may be fixed.
• the start of the evaluation period may be the first puff timing
• the end of the evaluation period may be 10 seconds after the first puff timing.
• setting the first puff timing can be regarded as synonymous with setting the evaluation period.
• notifying the first puff timing can be regarded as synonymous with notifying the evaluation period. That is, the terminal device 200 may be regarded as controlling the process of setting the evaluation period based on the user's behavior history and notifying the user of information indicating the evaluation period.
