What Is VR?

VR stands for Virtual Reality, a technology that creates a simulated environment through computer-generated 3D graphics or 360-degree video. The user can experience the virtual environment through a VR headset, which typically covers the eyes, ears, and sometimes hands.

The VR headset tracks the user's head and hand movements, and the virtual environment responds accordingly, creating a sense of immersion and presence. This allows users to feel as though they are physically present in the simulated environment, interacting with objects and experiencing events as if they were real.

VR technology has many applications, including gaming, education, training, and simulations. In recent years, it has gained popularity in eLearning as a tool to provide immersive and engaging learning experiences.

What Is the VR Timeline?

The history of VR technology can be traced back to the 1960s when Ivan Sutherland created the first head-mounted display (HMD) and developed a system called "The Sword of Damocles," which could display simple wireframe graphics.

Here is a brief timeline of the use of VR in education:

1977: Thomas Furness, a researcher at the Wright-Patterson Air Force Base, created the first VR system for educational purposes.

1991: The Virtual Reality in Education (VRE) The European Union launched a project to explore the potential of VR in education and training.

1993: The first VR-based educational game, "Myst," was released, which allowed players to explore a virtual island and solve puzzles.
