Ivan Sutherland is widely considered one of the pioneers in virtual reality (VR) technology. In 1968, he invented Sketchpad, a computer program that allowed users to create and manipulate simple 3D objects on a screen. This was a groundbreaking development in VR, as it laid the foundation for modern VR systems.
Sutherland’s motivation for inventing Sketchpad was to explore the possibilities of computer-generated imagery and to push the boundaries of what was possible with early computer technology. At the time, most computers were primarily used for numerical calculations and scientific simulations. Sutherland saw the potential for computers to create immersive and interactive experiences, and he set out to make this a reality.
One of the key features of Sketchpad was its ability to create 3D objects that could be viewed from any angle. This allowed users to explore and interact with virtual environments in ways that were previously not possible. Sutherland also introduced the concept of “perspective,” which allowed users to view objects from different angles and distances.
Sutherland’s work on Sketchpad laid the foundation for modern VR systems, which allow users to fully immerse themselves in a virtual environment. Today, VR is used in a wide range of applications, including gaming, education, medicine, and more. Sutherland’s pioneering work in this field has earned him numerous accolades and recognition as one of the most influential figures in computer science and technology.
