In 2021, during Meta's (formerly Facebook) grand unveiling of its metaverse vision, the company introduced avatars as the designated digital identities for self-expression in the virtual world. However, this initiative faced backlash, with some industry experts labeling the avatars as "Cringe." Our team delved into this matter, seeking insights from professionals to understand why Meta Avatars fall short in aesthetic appeal and explored an alternative AI-based technology. Reasons for the Lack of Appeal in Meta Avatars : Meta's avatars face difficulty in finding the right blend between a cartoonish and humanoid look. This results in the well-known "uncanny valley effect," where people experience discomfort when a humanoid avatar almost, but not entirely, resembles a real human. This sense of unease undermines the effectiveness of these avatars. Uncanny Valley Challenge : A notable concern arises in the skin shaders of Meta's avatars, creating an excessively glossy, plastic-like texture. This unrealistic shine takes away from the avatars' charm and authenticity, diminishing their relatability. Overly Radiant Skin Tone 3. Another evident issue lies in the design of the avatars' eyes. Specifically, the placement of pupils is inaccurately close to the lower eyelid. This departure from natural eye anatomy enhances the unsettling nature of Meta avatars, introducing epicanthus to everyone, irrespective of its natural presence. Flawed Eye Design: However, as we explored avatars, we found another problem in other avatar technologies that we had to solve too. Laborious Avatar Creation in Alternative Apps Apple's avatars and Snapchat's Bitmoji, widely used in messaging, employ a manual avatar creation toolkit. Users must meticulously design their digital twin by choosing from a wide range of facial features, such as eyebrows, chins, and noses. This method has three main drawbacks: Creating a realistic avatar requires users to possess specific artistic skills. The user experience can be daunting and complex. It imposes a considerable workload on developers, as they need to generate numerous versions of distinct facial components to meet varied user preferences. Our Avatar Maker's Machine Learning Approach to Avatar Generation Hence, our decision was to develop an Avatar Maker that achieves the balance between a cartoony and realistic appearance, steering clear of the uncanny valley effect. Moreover, it enables users to effortlessly craft their avatars using just a selfie photo, eliminating the need for laborious manual construction. Importantly, this technology functions locally on mobile devices, safeguarding users' sensitive data, especially facial images, by avoiding cloud-based processing. Here's a breakdown of how it works: The process of generating avatars begins with the creation of a 3D face model using a single selfie. A neural network utilizes this photo to generate a 3D mesh representation of the user's head. Following this, the mesh undergoes an automated stylization process, giving it a more cartoonish appearance, serving as the foundation for the avatar's head. Subsequently, additional neural networks come into play. They classify and synthesize various facial features like hair, eyebrows, facial hair, and color, adapting them to the user's selfie-based style. In the case of users wearing glasses, a specialized neural network identifies and generates a 3D version of them. Additionally, users have the option to apply various customizations such as headwear, makeup, bindis, and more to infuse their avatars with a vibrant and funky style. We accomplished this by gathering a distinctive collection of 20,000 3D High Fidelity Face Scans, showcasing a variety of individuals in terms of races, genders, and ages. This exclusive compilation plays a pivotal role in empowering Avatar Maker's customization and elevated facial performance features.
