Virtuaalimaailma, or virtual world, refers to a digitally constructed environment that allows users to interact with each other and with objects as if they were physically present. These worlds are created through computer graphics, networking infrastructure, and user interface technologies. They can be accessed via various platforms such as massively multiplayer online games, social VR spaces, and enterprise simulations.

The first significant virtual worlds appeared in the early 1990s with games such as Ultima Online and later expanded with platforms like Second Life, which introduced user-generated content and an internal economy. The mid-2000s saw the rise of dedicated social VR platforms, including Oculus Venues and VRChat, which emphasized real‑time spatial audio and body tracking. Today, virtual worlds are employed not only for entertainment but also for education, corporate training, remote collaboration, and therapy.

Key features of modern virtual worlds include persistent environments that continue to evolve even when users are offline, scalable multiplayer architectures that support thousands of concurrent users, and scripting systems that enable procedural content creation. Security and privacy concerns are addressed through authentication protocols, content moderation tools, and data encryption.

Technologically, virtual worlds rely on a combination of client–server and peer‑to‑peer networking models. Graphics are rendered using engines such as Unity or Unreal Engine, while physics simulations ensure realistic interactions. User navigation is typically facilitated through teleportation, walking, or flight mechanics, depending on the design goals. The continued advancement of haptic feedback, eye‑tracking, and mixed‑reality headsets promises to make future virtual worlds even more immersive and lifelike.
