Virtual identities stand in for a user or player in a virtual environment; they are social media profiles; digital subjects—of human and nonhuman agency. Virtual identities are often imagined as something distinct from the “self” of the user of digital media but technically and existentially they determine the ways a user navigates life online. Virtual identities, then, might also be a category that captures the ways identity itself is virtual; a force of existence that determines how subjects can orient themselves in the world. The questions of what virtual identities are, how they operate, and the kinds of material expression of personhood they afford and signify has been taken up in scholarship across the last thirty years from a variety of disciplines including computer sciences, critical race studies, game studies, gender and sexuality studies, literary studies, new media studies, social sciences, science and technology studies, and visual culture studies. As an imminent figure in early 21st-century life, virtual identities might describe subjects who exist in global digital media networks but who do not necessarily profit from their participation and labor, or who are not always visible. Despite the virtuality of virtual identities, their partial and fragmentary status, they exist as a technology by which to fix identity to an embodied subject—via facial recognition, or biometric scanning, or the coaxing and collection of personal data. The study of virtual identities remains an ongoing and significant task.
