Avatar (computing)

An avatar is a picture of you online.

It can be a small photo. It can also be a character in a game.

Some avatars look like a real person. Others look like a made-up character. You can change them to look unique. Some avatars even move! They can also help you talk to others. A computer can use an avatar to help you. These are sometimes called bots. An avatar helps people show who they are online.

An avatar is a way to show yourself online.

It can be a small, flat picture. People often call these profile pictures. Sometimes, an avatar is a 3D model. You might see these in video games or virtual worlds. In these worlds, you can move around. Some avatars look like real people. Others look like made-up characters. You can often change how they look. You might pick new clothes or hair.

This lets you show your own style.

The word avatar comes from a Sanskrit word. In Hinduism, it means a god coming to Earth. In games, it means you are in the digital world. Some avatars are not even made by people. They can be bots. A bot is an automated assistant. These use smart computer programs to help you. They can answer questions on a website.

This helps companies talk to their customers. Most people choose avatars that look like them. But some use them to be someone new.

An avatar is a way to show yourself in a digital space.

It can be a flat icon or a 3D model. In many online communities, people call them profile pictures or userpics. Some avatars are even just text in a game world. These digital bodies help you show your personality to others. You might use an image of your real face. Other times, you might pick a character that is totally different.

This lets you express your interests or your social status. Some people use special avatars to show they support a cause.

There are many ways these digital representations work. Some are small, square pictures near your name on a forum. These are often 80x80 or 100x100 pixels in size. Some avatars move because they are made of many images played in a loop. Other systems let you build a character from scratch. You might pick hair, clothes, or even body shapes. In some games, your actions change how your avatar looks. For example, a character might get stronger or gain tattoos.

This makes the digital world feel very real.

The word avatar has a very old history. It comes from a Sanskrit word used in Hinduism. In that religion, it means a deity descending to Earth. Early computer games and science fiction writers began using the term. A game called Avatar was released in 1979 on the PLATO system. In 1980, the writer Norman Spinrad used it in a novel. He described people using artificial realities to share knowledge.

This shows how the idea moved from stories to computers.

Many people helped make avatars popular in the digital age. Richard Garriott used the term for his 1985 game, Ultima IV. He wanted players to be responsible for their digital selves. In 1992, Neal Stephenson used the word in his book Snow Crash. He wrote about a virtual world called the Metaverse. Later, America Online introduced "buddy icons" in 1996. These grew into thousands of different icons for instant messaging.

Yahoo was the first to call these icons "avatars."

You likely see avatars every single day. You might see them on social media sites like Facebook. You also see them in big games like World of Warcraft. Some avatars are not even real people. They are called bots, which are automated assistants.

These use smart programs to talk to you on websites. A famous example is Anna, an assistant for IKEA. These digital helpers can guide you through a site. They make interacting with technology much easier for everyone.

An avatar is a graphical representation of a user, a character, or a digital persona. In computing, these representations allow people to project an identity into digital spaces. This can take many forms depending on the platform. Some avatars are two-dimensional icons used in internet forums. These are often called profile pictures, userpics, or formerly picons. Other avatars are three-dimensional models used in video games or virtual worlds. In some early text-based systems, such as MUDs, an avatar might not even have a visual appearance at all.

The way an avatar functions depends on its specific technical design. On many internet forums, an avatar is a small, square image. These typically measure between 80x80 and 100x100 pixels. They are placed near a user's post so others can identify them quickly. Some users upload their own designs or photos of themselves. Other systems provide a preset list of images to choose from. Some avatars are even animated. These consist of a sequence of multiple images that play repeatedly in a loop.

There are several distinct types of avatar systems used today. Some platforms use pixelized representations that users can customize. Others, like Trutoon, create a representation using a person's face with customized backgrounds. A unique type is the identicon. An identicon is a visually distinct geometric image. It is derived from a digest hash of a user's IP address or user ID. This allows an anonymous user to be visually identified without registering for an account. If an attacker uses a different IP address, a different identicon will appear.

The history of the term is rooted in ancient language and science fiction. The word avatar comes from the Sanskrit word "avatara." In Hinduism, this refers to the descent of a deity into a terrestrial form. The term entered computing through early games and literature. A 1979 PLATO role-playing game titled Avatar was one of the first uses. In 1980, novelist Norman Spinrad used the term to describe virtual experiences in his book Songs from the Stars. He imagined humans using a galactic receiver to engage in artificial realities.

Several key figures helped define how we use avatars in modern software. In 1985, Richard Garriott used the term for the game Ultima IV: Quest of the Avatar. He wanted the player's character to represent their actual self on Earth. He believed players should be held ethically responsible for their in-game actions. Later, Neal Stephenson popularized the term in his 1992 novel Snow Crash. He described the Metaverse, a fictional virtual-reality application. In his story, a user's social status was often tied to the quality of their avatar.

Avatars are widely used in massive digital ecosystems and social platforms. In video games like World of Warcraft or Second Life, they serve as the player's body. Some games allow for deep customization of physical features. For example, in Grand Theft Auto: San Andreas, a player can change clothing, tattoos, and body shape. In the world of instant messaging, America Online introduced "buddy icons" in 1996. These grew to include more than 1,000 different icons. Eventually, the term "avatar" replaced "buddy icon" as 3D customizable icons became mainstream. Yahoo was the first instant messenger to officially adopt the term "avatar."

Beyond human users, avatars can represent artificial intelligence. These are often called "bots" or embodied agents. They are driven by software rather than real people. Automated online assistants are a common example of this technology. They use natural language processing to interact with consumers. This helps organizations reduce training and operating costs. One famous example is IKEA's Anna, an avatar designed to guide users through the IKEA website.

Digital identity through avatars connects to broader studies in social science. Academic research examines how avatars influence communication and digital identity. Users often choose fictional characteristics to help them gain social acceptance. They might use an avatar to ease social interaction in a new group. However, many studies show that most users still choose avatars that resemble their real-world selves. Whether they are used for social media like Facebook or for professional sites like LinkedIn, avatars remain a primary way we navigate the digital world.
