User experience and limitations
The Sword of Damocles was the first VR system and it was created in 1968 by Ivan Sutherland. The system was designed to display a 3D wireframe model of an object and it used a head-mounted display. The user experience of the Sword of Damocles was quite limited, as the headset was quite heavy and the display was only in black and white. Additionally, the system only allowed for a limited field of view and it was not able to provide any audio or haptic feedback.
One of the main limitations of the Sword of Damocles was that it only supported a single user at a time. This was due to the fact that the system relied on a mainframe computer to generate the images and the computer could only handle one user at a time. The system also required a significant amount of computing power and it was not practical for widespread use.
Another limitation of the Sword of Damocles was that it did not provide any way for the user to interact with the virtual environment. The user was simply able to look around and observe the virtual object, but they were not able to manipulate it or interact with it in any way. This limited the potential uses of the system and made it difficult to imagine how it could be used in practice.
Despite these limitations, the Sword of Damocles was an important milestone in the development of VR technology. It demonstrated the potential of VR as a tool for visualizing 3D objects and it provided a foundation for future research and development in the field.
