         4 . The aerosol provision system of  claim 1 , wherein the aerosol provision system comprises a user input mechanism, wherein the interaction of the user with the aerosol provision system comprises an interaction of the user with the user input mechanism. 
     
     
         5 . The aerosol provision system of  claim 4 , wherein the user input mechanism comprises a manual actuation mechanism configured to alter the position and/or shape of the at least one wall via a mechanical adjustment of the adjustment mechanism. 
     
     
         6 . The aerosol provision system of  claim 5 , wherein the manual actuation mechanism is selected from the group comprising a slider, a pressable button, and a rotating dial. 
     
     
         7 . The aerosol provision system of  claim 1 , wherein the aerosol provision system comprises a controller configured to control the adjustment mechanism. 
     
     
         8 . The aerosol provision system of  claim 7 , wherein the controller is configured to control the adjustment mechanism based on an identification of the aerosol-generating material. 
     
     
         9 . The aerosol provision system of  claim 1 , wherein the at least one wall comprises an outlet wall comprising an outlet of the aerosol generation region, wherein the adjustment mechanism is configured to adjust the position of the outlet wall along an axis parallel to the direction of airflow during a user inhalation. 
     
     
         10 . The aerosol provision system of  claim 1 , wherein the at least one wall comprises a peripheral wall, wherein the adjustment mechanism is configured to adjust the position of the peripheral wall along an axis perpendicular to the direction of airflow during a user inhalation. 
     
     
         11 . A method of controlling an aerosol provision system for generating an aerosol from an aerosol-generating material in an aerosol-generating region; the method comprising:
 providing an adjustment mechanism configured to adjust the position and/or shape of at least one wall of the aerosol generation region to vary a volume of the aerosol generation region;   adjusting the position and/or shape of at least one wall based on an interaction of the user with the aerosol provision system.   
     
     
         12 . The method of  claim 11 , wherein adjusting the position and/or shape of at least one wall based on an interaction of the user with the aerosol provision system comprises:
 connecting a device part of the aerosol provision system to a cartridge part of the aerosol provision system, the cartridge part comprising the aerosol generating material;   identifying the aerosol generating material; and   adjusting the position and/or shape of at least one wall based on the identification of the aerosol-generating material.   
     
     
         13 . (canceled) 
     
     
         14 . (canceled) 
     
     
         15 .
