Claim 6:
7. The method of claim 1:
wherein accessing the canvas image comprises accessing the canvas image comprising:
a first vertical inner eye line;
a first vertical inner eyebrow line:
arranged between the vertical face centerline and the first vertical inner eye line;
laterally offset from the vertical face centerline by a first distance; and
laterally offset from the first vertical inner eye line by a second distance related to the first distance by a nominal ratio;

a first outer eyebrow vertex;
a first upper eyebrow are point:
arranged between the first vertical inner eyebrow line and the first outer eyebrow vertex;
laterally offset from the first vertical inner eyebrow line by a third distance; and
laterally offset from the first outer eyebrow vertex by a fourth distance related to the third distance by the nominal ratio;

the target first eyebrow geometry comprising the first set of curvilinear segments extending between the vertical inner eyebrow line, the first outer eyebrow vertex, and the first upper eyebrow are point;

further comprising, during the annotation period:
accessing an image captured by an optical sensor adjacent the projection system and facing the user; and
detecting a constellation of facial landmarks in the image;

wherein aligning the vertical face centerline of the canvas image to the center of the face of the user comprises:
centering the canvas image, projected onto the face of the user, within the constellation of facial landmarks in the image; and

wherein locating curvilinear segments, in the first set of curvilinear segments relative to features of the first eyebrow of the user comprises:
aligning the first vertical inner eye line, projected onto the face of the user, to an inner edge of a first eye in the constellation of facial landmarks detected in the image;
locating the first vertical inner eyebrow line between the vertical face centerline and the first vertical inner eye line according to the nominal ratio;
aligning the first outer eyebrow vertex, projected onto the face of the user, to an outer edge of a first eyebrow in the constellation of facial landmarks detected in the image; and
relocating the first upper eyebrow are point:
between the first vertical inner eyebrow line and the first outer eyebrow vertex line according to the nominal ratio; and
intersecting an upper edge of the first eyebrow in the constellation of facial landmarks detected in the image.
