Man-computer symbiosis is a very interesting topic in that it involves the inter-relation of humans and machines. In a sci-fi sense, we could see this as cyborgs, which may or may not play a part in our future, but in a realistic sense there has been a rise in interactive computer systems and interfaces that help synthesize the actions of man and computer. Some examples would be ZeroN, developed at MIT and an interface developed by James Pattern, also MIT. These two examples involve an open communication between man and computer, each can send messages and receive messages simultaneously as well as interrupt each other’s actions. Although many systems have been developed, they are only the beginning of this type of interaction, making the future that much more enticing.
