Ivan Sutherland, while conducting his initial
research in immersive technologies, Sutherland wrote The
Ultimate Display in 1965 in which he made the first advance
toward marrying the computer to the design, construction, navigation
and habitation of virtual worlds.
Sutherland predicted that advances in computer
science would eventually make it possible to engineer virtual
experiences that were convincing to the senses. Sutherland believed
in the ineffable potential of computers to transform the abstract
nature of mathematical constructions into habitable, expressive
worlds in the spirit of Lewis Carrol's Alice in Wonderland.
Although it was several years before the invention
of the personal computer, in 1970, Sutherland took a crucial
step towards the implementation of his vision by creating the
head-mounted display – a helmet shaped apparatus designed
to immerse the viewer in a visually simulated 3D environment.
