Communicating using speech recognition may seam the logical answer, though even when perfected it will have limitations. ‘ Simple tasks would be speeded up, for instance, if the message was short or required immediate response or the user needed their hands free for other tasks’. The more complex tasks, such as those used in graphics programs, will still require the user to physically interact with the computer.

This is the start of a new horizon in evolution, no longer do we talk commands, we think them.
Physical interaction will play a key role in the future of communication with computers. This has already been proved in the realm of V.R, yet to truly communicate we must be able to let the computer, ‘see’ what we are thinking. Just as the computer uses images to communicate, so will we. Future technologies will use control systems that are brain activated.
One recently conducted experiment consisted of a round table on which sat ten solar-powered robots. Two users sat on opposite sides of the table, strapped into headbands that record their brain waves. In front of each user was a small monitor, which displayed a readout of their own, and there partner’s, brainwave patterns. The computer compared both readouts and according to the results brightened or dimmed a bank of lamps above the table, thus affecting the behavior of the solar robots. The robots would move when the two brain patterns match.
