A computer-implemented method of providing feedback to a user of a shaving device during a shaving operation, the method comprising: determining values for one or more parameters, the one or more parameters comprising at least one of: (i) a shaving frequency measure indicating how often the user performs a shaving operation using the shaving device, (ii) a skin irritation measure indicating skin irritation experienced by the user during and/or following a shaving operation with the shaving device, (iii) a shaving closeness measure indicating how short the user desires their hair to be after a shaving operation with the shaving device, and (iv) whether the shaving device is used on wet or dry skin during the shaving operation; determining a pressure range for the user based on the determined values for the one or more parameters, wherein the pressure range has an upper pressure threshold and a lower pressure threshold; during a shaving operation using the shaving device, receiving pressure measurements representing the pressure with which the shaving device is being applied onto the skin of the user; comparing the received pressure measurements to the determined pressure range to determine feedback for the user relating to the applied pressures with respect to the determined pressure range; and outputting a feedback control signal to a feedback component associated with the shaving device, wherein the feedback control signal is for controlling the feedback component to provide the determined feedback to the user. determining values for one or more parameters, the one or more parameters comprising at least one of: (i) a shaving frequency measure indicating how often the user performs a shaving operation using the shaving device, (ii) a skin irritation measure indicating skin irritation experienced by the user during and/or following a shaving operation with the shaving device, (iii) a shaving closeness measure indicating how short the user desires their hair to be after a shaving operation with the shaving device, and (iv) whether the shaving device is used on wet or dry skin during the shaving operation; (i) a shaving frequency measure indicating how often the user performs a shaving operation using the shaving device, (ii) a skin irritation measure indicating skin irritation experienced by the user during and/or following a shaving operation with the shaving device, (iii) a shaving closeness measure indicating how short the user desires their hair to be after a shaving operation with the shaving device, and (iv) whether the shaving device is used on wet or dry skin during the shaving operation; determining a pressure range for the user based on the determined values for the one or more parameters, wherein the pressure range has an upper pressure threshold and a lower pressure threshold; during a shaving operation using the shaving device, receiving pressure measurements representing the pressure with which the shaving device is being applied onto the skin of the user; comparing the received pressure measurements to the determined pressure range to determine feedback for the user relating to the applied pressures with respect to the determined pressure range; and outputting a feedback control signal to a feedback component associated with the shaving device, wherein the feedback control signal is for controlling the feedback component to provide the determined feedback to the user.
