an electric hair clipper for cutting the hair on the housing; at least one comb associated with said hair clipper; a sensor array for detecting a position of the electric hair clipper relative to the housing; an indicator arrangement for indicating different zones of hair on the housing; and a control arrangement configured to interpret positional data provided by the sensor array and cause the indicator arrangement to illuminate one or more of said zones of hair on the housing. ### Claim 2 (depends on 1) The system of claim 1, wherein the housing is a mannequin head and includes an interior space, wherein the sensor arrangement and indicator arrangement are contained within the interior space. ### Claim 3 (depends on 2) The system of claim 2, wherein the mannequin head includes a plurality of openings such that light produced by the indicator arrangement can diffuse through an outer wall of the mannequin head. ### Claim 4 (depends on 1) The system of claim 1, wherein the electric hair clipper includes a taper lever for adjusting a blade gap between a movable blade and a stationary blade of said electric hair clipper. ### Claim 5 (depends on 4) The system of claim 4, wherein the taper lever is associated with a taper lever position detection arrangement, said taper lever position detection arrangement comprising a plurality of contacts arranged such that a contact of the taper lever can form an electrical contact with each of said plurality of contacts. ### Claim 6 (depends on 1) The system of claim 1, wherein the at least one comb includes an RFID tag affixed thereon, for uniquely identifying the at least one comb to an RFID reader of said control arrangement. ### Claim 7 (depends on 5) The system of claim 5, wherein the at least one comb includes a plurality of combs each having an RFID tag uniquely distinguishing the plurality of combs from one another, and wherein the control arrangement is configured to detect which one of said plurality of combs is attached to the electric hair clipper. ### Claim 8 (depends on 1) The system of claim 1, wherein the sensor array includes at least one sensor strip having a plurality of Hall effect sensors mounted on a base of said at least one sensor strip. ### Claim 9 (depends on 8) The system of claim 8, wherein the at least one sensor strip includes a plurality of sensor strips. ### Claim 10 (depends on 9) The system of claim 9, wherein the indicator arrangement includes at least one indicator strip, the indicator strip including a plurality of LED lights mounted on a base of said at least one indicator strip. ### Claim 11 (depends on 10) The system of claim 10, wherein the at least one indicator strip includes a plurality of indicator strips. ### Claim 12 (depends on 1) The system of claim 1, wherein the control arrangement includes a processor, an RFID reader in communication with the processor for receiving an RFID signal from an RFID tag of the at least one comb, and a receiver for receiving a wireless signal from a wireless communication module of the electric hair clipper. ### Claim 13 (depends on 1) The system of claim 1, wherein the wireless signal from the electric hair clipper includes an indication of a taper lever position of a taper lever of the electric hair clipper. ### Claim 14 (depends on 13) The system of claim 13, wherein the control arrangement is configured to compare the wireless signal corresponding to the taper lever position and the RFID signal to the position of the electric hair clipper relative to the mannequin head. ### Claim 15 A method of providing hair cutting training using a hair clipper training system, the hair clipper training system comprising a housing having associated therewith, an electric hair clipper for cutting the hair on the housing, at least one comb associated with said hair clipper, a sensor array for detecting a position of the electric hair clipper relative to the housing, an indicator arrangement for indicating different zones of hair on the housing, and a control arrangement configured to interpret positional data provided by the sensor array and cause the indicator arrangement to illuminate one or more of said zones of hair on the housing, the method comprising: illuminating a first zone of hair on the housing using the indicator arrangement; detecting whether the electric hair clipper is in proximity to the first zone via the sensor array; determining whether a correct comb is attached to the electric hair clipper; detecting whether a taper lever of the electric hair clipper is in a correct position; and providing an indication, via the indicator arrangement, when the electric hair clipper is not in proximity to the first zone.
