Keyboard has buttons that they float with magnets


He is funny as the keyboards are personal things. We in accustom them with them and when we change, we find odd the sound that they make, the resistance of the keyboard keys and of time in when until we delay in adapting them with buttons in different places. Many promise to create a keyboard that is really very better that the others, but so far this was a promise without fulfilment.

Machine reads thought to control devices


It forgets the control remote. A new technology demonstrated in Japan can become possible to control devices without moving a muscle, only with the cerebral activity. The “interface brain-machine”, developed for the Hitachi, analyzes light changes in the sanguineous chain in the brain and translates the cerebral movement in electric signals. A species of helmet was connected through fiber optics to a device of mapping, that in turn was connected to a train of controlled toy for computer, in a demonstration in the laboratory of advanced research of the Hitachi, in Hatoyama, in Japan. “It breathes deep and it relaxes”, said Keu Utsugi, researcher of the project, while it demonstrated the device in the last Wednesday. To its signal, another researcher, using the helmet, made simple mental arithmetic and the train was onward, pparently indicating cerebral activity in the cortex frontal, responsible for the solution of problems. “To activate that region of the human brain - making accounts or singing a music - it is what it makes the train to walk”, says Utsugi. When the person pára to make the calculations, the train also pára. Under the interface of the machine it is a technology called topography optics, that sends small amounts of light infra-red ray through the surface of the brain, to mapear changes in the sanguineous chain. Although this type of technology traditionally to be focada in medicinal uses, companies as Hitachi and Honda have studied commercial applications. Scientists of the Hitachi are wanting to develop a remote control of television commanded only for the mind. Already the Honda, whose monitorial interface the brain with a machine of magnetic resonance, is empolgada to make an intelligent interface for automobiles of next generation. The technology can one day substitute remote controls and keyboards, beyond assisting incapacitated people to operate chairs of wheel, beds or even though electric members. Initially, the idea is to use the device for people with complete paralysis if to communicate. One of the great advantages of the technology of the Hitachi is that it possesss sensors that do not invade the brain physically. Old experiences requested the one implantation chip under the skull. However, still problems exist. The size is the first one, and the Hitachi already developed a band (as those used ones for the tenistas) that it weighs about one kilo. Another problem is the interference of other cerebral activities and as to ignore them. “Any interface commercial brain-machine sufficiently spread out is a little distant”, says Koizumi. It also said that the technology is amused and could be used with toys. “Sufficiently he is amused to move the train with the thought”, declared. AP Copyright 2007 Associated Press.
