1. An aerosol-generating device, comprising:
a housing comprising an air inlet, an air outlet, and an airflow passage extending therebetween;
an aerosol-generating element disposed within the airflow passage and configured to generate an aerosol;
a sensor coupled to the housing and configured to generate a time-dependent airflow signal corresponding to a time-dependent strength of a user puff at the air outlet;
a haptic output element coupled to the housing; and
a circuit operably coupled to the sensor so as to receive the time-dependent airflow signal during the user puff,
the circuit being further operably coupled to the haptic output element and configured to actuate, based on the time-dependent airflow signal, the haptic output element at time-dependent frequencies or at time-dependent intervals during the user puff,
the circuit being further configured to:
actuate the haptic output element at shorter intervals or at higher frequencies during the user puff based upon an increase in the time-dependent airflow signal, and/or
actuate the haptic output element at longer intervals or at lower frequencies during the user puff based upon a decrease in the time-dependent airflow signal.
