मैं क्या हूँभौंह उठाने वाला नाश्ता?

भीतरी भौंह उठाने वाला, या AU1, एक है चेहरा क्रिया संहिता प्रणाली (FACS) action unit (AU). Its function is to raise the medial brow/forehead area, and its action is triggered by the contraction of the medial region of फ्रोन्टलिस. It can difficult find clean references भीतरी भौंह उठाने वाला. When building FACS references, many sources fail to:

1. Find actors who can voluntarily trigger their medial frontalis without also contracting the lateral area of frontalis or corrugator supercilii. 
2. मॉडलों को उचित रूप से निर्देशित करें to perform medial frontalis contraction.

In our everyday lives, most of us can effortlessly raise our inner brows without thinking twice; however, when commanded to, many people struggle to isolate this motion.

FACS संदर्भ और भ्रामक जानकारी

I recently (2020) critiqued a set of FACS shapes for a client and noticed his भीतरी भौंह उठाने वाला आकार में कुछ कॉर्रुगेटर था (से भौंह नीचे करने वाला) गलती से मिला दिया गया।.

Client’s Inner Brow Blendshape + My Notes:

कोर्रुगेटर को जोड़ना भीतरी भौंह उठाने वाला यह एक बहुत ही आम गलती है। यह समानता आंशिक रूप से इस तथ्य के कारण है कि: अच्छे संदर्भ मिलना मुश्किल है!

Even my client – an established industry artist with a great portfolio and CV – unknowingly added corrugator features to his model, because he trusted a tainted reference. The reference he used was from a prominent anatomy and facial expression book: चेहरे के हाव-भावों की संरचना. Many art students and professionals use this textbook. It is a great textbook, but some of its FACS shapes are inaccurate.

Reference used by client:

See the vertical and wavy lines in the center of the forehead in the images below? Those vertical lines are from a brow knitting muscle known corrugator supercilii.
