In theorem-proving programs, computers find precedents in experience, and in the SAGE System, they suggest courses of action.
With further improvements, technology will improve such that it rivals or exceeds some of the conventional human capacities. As bold as the assertion of direct brain-computer communication may sound, its implementation, and all the powerful implications derived from it, merely rests on two assumptions.
In addition, the communication speed between the brain and the external world indicated by the thin red communication pipe is slow. Let us examine some of them to see more clearly what is needed and what the chances are of achieving it. Trie memory is so called by its originator, Fredkin , because it is designed to lickliser retrieval of information and because the branching storage structure, when developed, resembles a tree.
Then follow directions to the function, which is stored in one or another of several ways, either further trie structure or “list structure” often being most effective.
In addition he identified two reasons for Licklider to have considered such a concept as a symbiotic human computer relationship at all as beneficial, to be firstly, for it might bring about an advantage emerging from the use of a computer, such that there are similarities with the necessary methodology of such a use i. The brain can process information from many different sources in parallel much computational breadth horizontal arrowsbut is fairly slow in processing any particular algorithm little computational depth.
J.C.R. Licklider (1915-1990)
Given a suitable physical interface, one may use two different languages to communicate with the brain. Tactile perception of ultrasound.
This figure illustrates the exploding increase in research activity in number of peer-reviewed papers over the past 15 years. Acknowledgments The author would like to acknowledge the helpful discussions with Dr. In another and more realistic sense, they store all the possible arguments in the framework structure of the memory.
To be rigorously correct, those characterizations would have to include many qualifiers. J Acoust Soc Am. Because the present vision depends largely on technological improvements rather than on hopeful speculation, and llcklider its realization is subject to the same forces that have governed the course of many previous technical developments, it is, in the end, a logical step in our own evolution.
Second, one may communicate with the brain by establishing a new mutual language, i. It contains receptors that are preferentially responsive to particular smells. In this case, detection of man-compjter temporary intent could be correct, but the action would still be undesirable.

Preliminary analysis of his problems and time scales suggests that a corporation president would be interested in a symbiotic association with a computer only as an avocation.
In Mathematical Theory of Communication [ ], Claude Shannon showed that any noisy communication channel has a channel capacity measured in bits per second. Throughout the period I examined, in short, my “thinking” time was devoted mainly to activities that were essentially clerical or mechanical: Because this information is provided by a computer, it could be accessed and modified by third parties, which may allow them to influence our actions. The trie memory system, on the other hand, stores both the functions and the arguments.
I am also indebted to Dr. For the purposes of real-time cooperation between men and computers, it will be necessary, however, to make use of an additional and rather different principle of communication and control.

Man-Computer Symbiosis – Wikipedia
Nevertheless, certain genotypic differences in capability between men and computers do stand out, and they have a bearing on the nature of possible man-computer symbiosis and the potential value of achieving it. Trends in cochlear implants. Just as society has responded to these techniques e. This part proceeds to an outline of an investigation sub-headed A Preliminary and Informal Time-and-Motion Analysis of Technical Thinkingin which Licklider investigated his own activities during the spring and summer of The communication process Semantically rich representations in the brain are translated into syntactic keywords, void any semantics and encoded into motor actions that are man-ccomputer and detected by a computer.
Part 5 is the final part of the article and is titled Prerequisites for Realization of Man-Computer Symbiosis. There are many man-machine systems.
