1. A system comprising:
a hair cutting device having a cutting element for cutting a subject's hair;
a localisation unit for acquiring location data indicative of a location of the cutting element relative to a body part of the subject;
a timer unit for measuring time data associated with usage of the hair cutting device; and
a processing unit in communication with the hair cutting device, the localisation unit and the timer unit, the processing unit being configured to:
determine, based on the acquired location data, a region of the subject's body part corresponding to the location of the cutting element;
determine, based on the time data and the determined body part region, an amount of time spent by the cutting element within the determined body part region;
determine, based on the determined amount of time, an operating parameter to be applied to the hair cutting device when the cutting element is within the determined body part region; and
operate the hair cutting device according to the determined operating parameter.
