Stencils and gauging device for aesthetically pleasing eyebrow shaping
View Patent ↗A novel gauging device and associated stencils facilitate the shaping of eyebrows according to a Golden Ratio standard. The gauging device is adapted to be placed over a woman's face and maintained in a fixed position relative to her eyes and nose. A nosepiece and knobs are adjusted such that a lower end of a guide rod may be rotated about various points relative to the nose and held in predetermined angles relative to the nose and eyes, possibly supported magnetically on a lower track adjacent the nostrils and an upper track above the eyebrows. An eyebrow stencil is held in a desired position relative to the previously positioned guide rod, which facilitates convenient application and symmetrical shaping, preferably with frictional clamps for permitting the stencil to be shifted in place so that a particular portion of the stencil is properly aligned with the guide rod after the guide rod has been aligned with an appropriate Golden Ratio marking on the stencil. Each stencil may be provided with more than one set of such markings to accommodate not only different eyebrows of different sizes, but also to adjust the eyebrow's ideal Golden Ratio “High Point” to complement facial proportions (preferably represented by a single Facial Ratio Value or “FRV” that takes into account several different measured ratios) that deviate substantially from an ideal Golden Ratio. A slim tab between the upper and the lower edges of the stencil cut-out preferably provides a convenient reference mark for the “High Point” of the unadjusted cut-out.
1. A method to categorize a person's facial proportions, comprising:
determining at least one horizontal facial proportion between at least two horizontal distances across the person's face;
determining at least one vertical facial proportion between at least two vertical across the person's face;
calculating a mean of the thus determined horizontal and vertical facial proportions to thereby determine a Facial Ratio Value (“FRV”); and
comparing the FRV with the Golden Ratio.
2. The method of claim 1 , wherein:
at least two of said horizontal distances are selected from Outer-edges-of-Eyes, Length-of-Mouth, Centers-of-Irises and Width-of-Nose; and
at least two of said vertical distances are selected from Hairline-to-Chin, Hairline-to-Nosetip, Eyeline-to-Lips, and Eyeline-to-Nosetip.
3. The method of claim 1 , wherein the comparing step further comprises determining the FRV for each of a random sample of faces to thereby determine a numeric value for one standard deviation of the thus determined random FRVs from the Golden Ratio; and assigning a Simplified FRV (“SFRV”) representative of zero to a FRV within half of the thus determined standard deviation from the Golden Ratio, assigning a positive integer SFRV to a FRV that is greater than the Golden Ratio by more than said half of a standard deviation, and assigning negative integer SFRV to a FRV that is less than the Golden Ratio by more than said half of a standard deviation.
4. The method of claim 3 , wherein the SFRV is assigned as follows:
0 if the FRV ranges from 1.57 to 1.67;
−1 if the FRV ranges from 1.47 to 1.56;
+1 if the FRV ranges from 1.68 to 1.77;
−2 if the FRV ranges from 1.37 to 1.46); and
+2 if the FRV ranges from 1.78 to 1.87.
