The development of virtual reality has been driven by the confluence of three improvements to display technologies:
- Field of View: the size of the area that we can see
- Stereoscopic 3D: the depth cue from viewing the world from two different horizontally separated viewpoints
- Interactivity: the ability to change the virtual environment in real time
In this chapter, we are going to illustrate the history of virtual reality and how earlier designs have served as inspiration for today, even a few older ideas that we have not quite duplicated with our current generation of VR hardware.
We will investigate the following:
- 19th century panoramic paintings
- Cycloramas and Sensoramas
- NASA Moon Landing Simulators
- Nintendo Powerglove
- Hasbro Toaster
Static 2D images, whether paintings or photographs, are poor representations of reality. As such, people have striven to enhance their images, to make them more realistic and immersive since the first flickering shadows added motion to cave paintings 20,000 years ago. Simple puppets added motion and then depth. More complex solutions were designed: motion and audio effects were added to Greek and Roman temples to give a complete sensory experience. Doors would open without apparent human interaction, thunder would rumble overhead, and fountains would dance: all designed to create an augmented experience beyond simple static statues and paintings.
