An avatar is a virtual representation of you in the vurtual world that can take the form of two- or three-dimensional models, and made to resemble anyone or anything imaginable.

What is an Avatar?

An avatar is a virtual representation of an individual online. Avatars can be used for chat, instant messaging and multiplayer games.  In chat they may take the form of realistic photos-like images, characters who resemble users slightly or cartoon figures.  They may even serve as symbolic icons in Internet forums, 3D virtual worlds and text-based games. Avatars have even been utilized in medical research by implanting experimental drugs into patient tumors, then remotely controlling it through avatars.

Avatar first entered popular parlance during 1996 when AOL introduced limited “buddy icons” into its instant messaging service. As 3D avatars became more commonplace in PC games, the term evolved to refer to any customizable icon representing computer users. By 2000, Yahoo included avatars into their instant messenger service as standard features in Internet chat rooms.

Avatars can also serve as the visual representations of artificially intelligent bots or automated agents that interact with users through speech, images and movement. Avatars have become widely utilized across numerous online businesses including customer support services, social networks and search engines.

Some avatars are specifically created to promote specific products or services. These brand avatars can be seen in advertisements, videos, websites and mobile apps to increase brand recognition and generate sales. This is especially helpful for start ups where the cost of advertising may be prohibitive.

Another form of avatar is a digital twin, which acts as an electronic replica of someone or organization. They’re often employed in business applications such as telemedicine and e-commerce to provide customer support without incurring additional travel costs for staffing purposes or staff hiring costs. They’re also useful tools in scientific research and education settings.

A Way To Interact

Users may choose to create avatars to represent themselves in certain ways, such as striving to meet specific goals or imitating other people. Others have revealed that avatar creation processes vary depending on activity context (for instance gaming scenarios) while few studies address avatar use with primary communication goals, emphasising the need for further study on this topic.

In 1979, Avatar for PLATO marked the first use of “avatar” as a term used in games. Richard Garriott de Cayeux encouraged players to imagine themselves as their avatar while playing this role-playing video game, leading to an increase in popularity for games allowing users to assume an imaginary character’s persona while playing them.

Eye-tracking experiments have demonstrated how avatars in certain games interact with each other through speech or by showing different emotions, with these interactions having an impactful influence on user perception of these avatars.  Participants reported feeling more at ease around avatars belonging to friends than strangers.

Researchers have noted that avatar use may contribute to blurring boundaries between real and digital worlds, leading to issues like cyberbullying or identity theft, as well as acting as tools of manipulation or creating feelings of isolation or social anxiety. Due to these concerns, many individuals are exploring other forms of online identity like Self Sovereign Identity (SSI). This form gives individuals full control of their digital persona.


Digital avatars have made significant headway beyond video gaming in recent years, becoming part of education, healthcare and business industries alike. Students can utilize these avatars to increase student engagement during lectures, while creating immersive learning experiences.  They may even serve as personalized tutoring solutions!

Avatars have increasingly become a way of representing people online and for social media use. Snap’s Bitmoji and Apple Memoji are two such avatars which enable users to craft a personalized online persona.

As part of rehabilitation and therapy treatments, avatars are being designed as companions for patients in rehabilitation and therapy settings. Avatars provide emotional support, cognitive training assistance and therapeutic benefits that improve quality of life for these individuals. Using avatars may alter how we live, work and play in future.

New technologies are making avatars look more life-like, yet their integration into users’ lives remains incomplete. It is especially crucial that avatars be used responsibly with regards to privacy concerns, by giving users control over data collected about themselves and their avatar.

Legal considerations regarding avatar use should also be addressed, and one way is by creating a means to identify who stands behind an avatar and imposing liability upon them for certain acts.


Gravatar, short for Globally Recognized Avatar, is a service that allows users to create and manage their online avatars. An avatar is an image or representation that represents an individual in the digital world. Gravatar provides a centralized platform where users can associate their email addresses with a chosen avatar, which then appears whenever they interact with Gravatar-supported websites.

So, how does Gravatar work? It’s quite simple. Users sign up for a Gravatar account by linking their email address(es) to it. They can then upload an image or choose one from the existing options provided by Gravatar. Once the avatar is set, it becomes associated with the email address and is automatically displayed whenever that email address is used to comment on Gravatar-enabled websites. 

One of the significant advantages of using Gravatar is its universality. Since Gravatar is supported by a vast number of websites and platforms, users can have a consistent avatar across multiple online platforms without the need to set it up individually on each website. This saves time and effort while ensuring a recognizable online identity.
