## Abstract

A personalized optimal head shape implementation system capable of deriving an optimal spline curve between head shape measurement data generated by scanning a head shape of a subject and optimal head shape data generated by applying a golden ratio of a Fibonacci sequence to the head shape measurement data and providing a customized optimal head shape mold for the subject based on the optimal spline curve.

## Claims

### Claim 1

A personalized optimal head shape implementation system, comprising:
a head shape scanner configured to scan a head shape of a subject and generate head shape measurement data of the subject;
a head shape implementer configured to apply a golden ratio of a Fibonacci sequence to the head shape measurement data of the subject generated by the head shape scanner to generate optimal head shape data, wherein the optimal head shape data comprises a plurality of ratios having the golden ratio of the Fibonacci sequence, wherein the plurality of ratios comprise:
a ratio of a nose length and a vertical length between a root of a nose and a subnasal portion of the nose,
a ratio of a horizontal length between a procerus and a tragus and the nose length
a ratio of a horizontal length between the root of the nose and an auricle radix superior and the nose length,
a ratio of a vertical length between a vertex and a right tragion and the horizontal length of the root of the nose and the auricle radix superior,
a ratio of a vertical length between the vertex and a left tragion and the horizontal length between the procerus and the tragus,
a ratio of the horizontal length between the procerus and the tragus and the vertical length between the vertex and the left tragion,
a ratio of a vertical length of the head and the vertical length between the vertex and a right tragion, and
a ratio of a length of an arc between an inter-tragus and the vertex, and the vertical length of the head;
a head shape analyzer configured to preset control points related to the head shape and derive an optimal spline curve between the head shape measurement data and the optimal head shape data using the preset control points; and
a display configured to display a customized optimal head shape for the subject using the optimal spline curve derived by the head shape analyzer,
wherein the personalized optimal head shape implementation system is configured to form a customized optimal head shape article having a physical shape that is at least partially defined by the optimal spline curve.

### Claim 2 (depends on 1)

The personalized optimal head shape implementation system of claim 1, wherein the head shape scanner is a contact type measuring device having a robot arm shape and scans the head shape of the subject to generate the head shape measurement data.
