Avatar

A graphical representation of a user within a virtual environment or digital platform. Avatars can range from simple icons to fully customizable 3D virtual humans that mirror user movements. In accessibility research, avatar customization has been shown to increase engagement and improve performance for users with autism spectrum disorder, as it allows incorporation of individual interests and preferences. Self-avatars (representations of the user's own body) and virtual human companions (other characters users interact with) can both be customizable, with research showing different psychological effects for each type.
