A wearable device includes a housing, a biometric information obtainer that is provided on one surface of the housing and obtains biometric information of a user, a functional material cartridge that is accommodated in the housing and stores a functional material, a mouthpiece connected to the functional material cartridge and configured to discharge the functional material, and a controller that provides a recommendation on inhalation of a functional material based on the biometric information obtained by the biometric information obtainer.

Wearable device

A user authentication apparatus trains a user authentication model by using biometric data of a user which was used in previous user authentication as training data, and performs user authentication by using the trained user authentication model.

Apparatus and method of performing user authentication

Provided is a method of cleaning an aerosol generating device, the method including: receiving a user input for performing a cleaning operation; obtaining information about a performance history of the cleaning operation in response to the user input; setting a mode of the cleaning operation to one of a plurality of cleaning modes based on the information about the performance history; and performing the cleaning operation according to the set cleaning mode.

Apparatus for generating aerosols and method for cleaning the same

An aerosol generating device includes a heater configured to heat an aerosol generating material to generate aerosol; a controller configured to: calculate a current flowing through the heater based on a predefined resistance of the heater and power supplied to the heater, measure the current flowing through the heater, and control the power supplied to the heater based on a difference between the calculated current and the measured current.
