A spectacular rise in computer speed, portability, and versatility has led to the foremost use of these machines in contemporary society and technology. Scientific advances and the development of new technology, such as computers based on light, Dna, or portion mechanics, will allow computers to fill even more roles. Computers whose behavior is practically or entirely indistinguishable from humans may be advanced some time in the future.

 

 

Another application for the increased power of computers involves a different kind of goal - replicating or imitating a person's environment rather than his or her thinking processes.

Human senses such as sight, hearing, and touch are the sensory "inputs" by which the brain creates human experience. The world has a three-dimensional look and feel. Pictures, graphics, video, and other forms of entertainment or communication are poor mimics of these involved sensations because they do not gift enough information. Computer monitors display flat images, for instance; they are only capable of suggesting through assorted illusions and perspectives the wealth of facts added by the perception of depth. But advanced computers may be able to concentrate much more facts in their representations - enough facts to generate a "virtual reality."

Simulations of reality are staples of science fiction, such as in the 1999 film The Matrix and its sequels, in which provocative machines have subdued and exploited the human citizen by stimulating people's brains and creating an synthetic world. More positively achievable simulations involve the presentation of an array of facts to the user's senses. Special goggles or headgear gift three-dimensional images, and Special gloves stimulate tactile (touch) senses of the user's hand. What the user sees and feels mimics the real world, yet it is a computer simulation - a virtual reality.

Replicating rich sensory caress requires a lot of computational power. Even more power is needed if the users are allowed to interact with the virtual environment as they would with the real one. Movement of the head, for instance, changes optical perspective. If a virtual reality user moves his or her head, the images presented by the computer should turn accordingly. Quick responses to these changes need extremely fast computers, otherwise there is a lag between the time the user moves and the updated image. Such lags ruin the "reality" of the simulation. (And the lags can make the user quite dizzy.)

Other simulations exertion to generate a "world" for a amount of observers at the same time. At Iowa State University in Ames, researchers have built a 1,000-cubic-foot (28-m3) room - 10 feet (3.05 m) to a side - in which detailed images and sound generate a rich sensory caress for its occupants. The room equipment was upgraded in 2007, and consists of 96 computer processors that operate 24 digital projectors and an eight- channel surround sound system. The simulator, known as C6, has six screens - one for each of the four walls, one for the floor, and one for the ceiling - to envelope the viewers. Being inside C6 is much closer to reality than watching a small screen.

The inherent uses of these simulations go beyond a amazing caress such as flying a fast jet or walking on the Moon. Recreating situations or objects in rich information allows inspectors to scrutinize structures for damage, young pilots to train in realistic flight situations, and many other applications. Technology, such as flight simulation, is enhancing with the use of virtual reality.

But the need for computer speed continues to be a limiting factor. As computers get faster, their role in society will keep expanding. There would seem to be few if any limits to how far this frontier of computer science can go.
