The UCF and Google Validated Avatar Library for Inclusion and Diversity (VALID) consists of 210 fully rigged and perceptually validated virtual avatars designed to advance diversity and inclusion. The library features avatars of seven different races (American Indian and Alaskan Native (AIAN), Asian, Black, Hispanic, Middle Eastern and North African (MENA) Native Hawaiian and Pacific Islander (NHPI), and White), providing a diverse selection for researchers to use in their studies. The validated labels can facilitate research on the impact of avatar race, and researchers can choose to use the labels for studies aimed at individuals from different racial backgrounds or same-race labels for specific study populations. Avatars were created using a process that combined data-driven average facial features with extensive collaboration with representative stakeholders from each racial group.

The perception of each avatar's race and gender were evaluated on a global scale. We conducted a large online study ($n=132$) with participants from 33 countries, self-identifying as one of the seven represented races, to determine how the avatars are perceived. The statistically validated labels for each avatar can be found in the chart below, and also in the paper. Please note that different communities may perceive the race of an avatar differently, particularly within community (same-race).
Additional metadata, including agreement rates disaggregated by all participant backgrounds, are found in the Metadata folder. Please read the paper for more detailed information.

ABSTRACT={As consumer adoption of immersive technologies grows, virtual avatars will play a prominent role in the future of social computing. However, as people begin to interact more frequently through virtual avatars, it is important to ensure that the research community has validated tools to evaluate the effects and consequences of such technologies. We present the first iteration of a new, freely available 3D avatar library called the Virtual Avatar Library for Inclusion and Diversity (VALID), which includes 210 fully rigged avatars with a focus on advancing racial diversity and inclusion. We also provide a detailed process for creating, iterating, and validating avatars of diversity. Through a large online study (n = 132) with participants from 33 countries, we provide statistically validated labels for each avatar’s perceived race and gender. Through our validation study, we also advance knowledge pertaining to the perception of an avatar’s race. In particular, we found that avatars of some races were more accurately identified by participants of the same race.}
}Avatars are available in the FBX format and are ready to use in most game engines, such as Unity and Unreal. All avatars have embedded textures and materials. Unity usually does not extract them automatically. Below are instructions on importing and animating sample avatars:
Avatars should now be ready to animate.
NOTE: If you are using an avatar with long hair, you need to apply the hair shader in /HairShader to the wig game object to turn off mesh culling. By default, Unity culls two-sided meshes.
