Gesture recognition user interface for an aerosol delivery device

An aerosol delivery device comprising:

• a housing;
• a microprocessor;
• and
• a motion sensor within the housing and configured to detect a defined motion of the aerosol delivery device caused by user interaction to trace a character with the housing and thereby perform a gesture, the motion sensor being configured to convert the defined motion to an electrical signal that conveys data about the defined motion of the aerosol delivery device, the data including samples of velocity of the aerosol delivery device, or data from which the samples of velocity are determinable,
• wherein the microprocessor is configured to receive the electrical signal, recognize the character and thereby the gesture, and an operation associated with the gesture, based on the electrical signal, and control at least one functional element of the aerosol delivery device to perform the operation, the microprocessor being configured to recognize the character including the microprocessor being configured to recognize a pattern in the samples of velocity, the pattern being associated with the character and thereby the gesture, the character and thereby the gesture being user-defined for the operation comprising altering a locked state of the aerosol delivery device.
