An automated hairstyle processing method, an automated hairstyle processing system, and an automated hair cutting device, the system including a memory unit arranged to store a predefined hairstyle model including hair property representing values and body shape representing values, a sampling unit arranged to sample an actual body shape, of a to be treated subject, involving detecting deviations from a model body shape portion of the predefined hairstyle model, a processing unit arranged to adapt a hair property model of the predefined hairstyle model, when deviations between the actual body shape and the model body shape portion are detected, so as to compensate the actual body shape deviations, the adaptions to the hair property model being local adaptations.

The invention is directed to a device used to help a stylist cut hair, such as during training. Specifically, the training device includes a fastener that is used to removably attach the device at a particular location in a client's hair. The device also includes a plurality of arms attached to the fastener at predetermined angles. The angles are beneficial, ensuring the user holds a section of hair at the proper position. The device can be used as a training tool for new stylists, or with experienced stylists to maintain skills. Advantageously, the arms of the device can be attached and removed as desired by the user, allowing the device to be customized for a particular client.

A positioning device includes a frame having at least a front frame and one or more side frames; and a plurality of positioning interfaces, the positioning interfaces configured to at least one of transmit signals and receive signals, the signals being configured to at least partially determine at least one of position and orientation of a hair cutting device, the plurality of positioning interfaces positioned at various intervals about the frame. The front frame includes at least one structural feature designed to contact at least one feature of a user's face, and the front frame extends at least partially across said user's face.

There is provided a computer-implemented method for generating an optimized hairstyle guide for use with a hair clipper. The method comprises acquiring (202) a plurality of reference points for mapping a hairstyle onto the head of a subject, receiving (204) a first user input for adjusting at least one of the relative position and the hair length value of a selected reference point, adjusting (206), based on the first user input and one or more predetermined rules, at least one of the relative position and the hair length value of one or more non-selected reference points, and generating (208) an optimized hairstyle guide for mapping the hairstyle.

The present invention provides a barber instrumentality useful for verifying, establishing and producing accurate, symmetrical hair lines and hair art designs. In particular, methods are provided herein for the use of the instrumentality wherein precise measurements can be taken to accurately verify, establish and produce symmetrical hair lines and hair art designs on face, forehead, scalp or neck.

The Hair Length Hand Guide allows for the user to easily measure and cut hair at uniform lengths. The guide is mounted between any two fingers on either hand such that the guide support extends perpendicular to the bottom of the hand when the user's fingers are extended straight and the hand is flat. To measure hair, the user can run their fingers at an angle in a combing motion through the hair grasping any that needs to be cut at its base. The curvature on the bottom of the guide support then allows the user to rock their hand back, pulling the hair grasped between their fingers straight while bringing the hand parallel to the cutting surface. The user can then cut any hair that extends beyond the top of their fingers for a uniform cut.

A cutting head for a device for cutting hair is disclosed. The cutting head has an optical system configured to direct a laser beam along an optical axis across a cutting zone within the cutting head. The optical system has a variable focus lens configured to control the position of the focal point of the laser beam along the optical axis within the cutting zone.

The present disclosure relates to an automated hairstyle processing method, an an automated hairstyle processing system, and an automated hair cutting device, the system (10) comprising a memory unit (48) arranged to store a predefined hairstyle model (90) including hair property representing values and body shape representing values, particularly head shape representing values, a sampling unit (76) arranged to sample an actual body shape portion, particularly an actual head shape, of a to be treated subject (12), involving detecting deviations from a model body shape portion of the predefined hairstyle model, a processing unit (42) arranged to adapt a hair property model (94) of the predefined hairstyle model, in case deviations between the actual body shape and the model body shape portion are detected, so as to compensate the actual body shape deviations, the adaptions to the hair property model (94) being local adaptations.

A method for the cutting of hair, in particular for the cutting of human head hair, wherein a slice of hair is taken up and is guided by a hand, namely the guide hand, with the slice of hair being pinched between two fingers, namely the guide fingers of the guide hand, and wherein the slice of hair is cut along the guide fingers using a cutting device that is actuated by another hand, namely the cutting hand. The guide hand is moved continuously or step-wise after the taking up of the slice of hair and the cutting of the slice of hair takes place at least partially during the movement of the guide hand or, in the case of step-wise movement, during and/or between the movement steps.
