Virtual Influencers in the Real World

Communications of the ACM 

The next time you buy a flashy new outfit after browsing Instagram, or tap the heart button on a particularly compelling TikTok video, you might discover that the person who posted it isn't real--and you might not care at all. That is, if virtual influencers (and their creators) get their way. A virtual influencer is a digital personality that posts on social media to build an audience of passionate fans, just like a human influencer; at least, that's how it seems. In reality, a team of humans uses computer-generated imagery (CGI), motion capture, and marketing magic to give a digital avatar a voice, a life, and a brand. The result makes virtual influencers seem like, well, real people.
