Researchers at the University Miguel Hernández (UMH) Elche have designed an interactive pioneer in the world that allows a user to use a computer and surf the Internet using only brain signals.
The device (interface), presented today at the Campus of Elche has been developed by the Group Biomedical NeuroEngineering this university and the Center for Biomedical Research Network in Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN).
The interface, which leads to an interactivity between the user and the computer consists of a cap that incorporates up to more than fifty of electrodes that pick up brain activity.
Through amplifiers, the computer processes the recorded signals and the algorithms developed by researchers determine what the person thinks.
"Allows to search the Internet, using the mouse, correct movements, write a document, open a folder or create a file", explained researcher and professor at UMH Eduardo Fernandez.
Although initially not allowed to use sophisticated programs like Photoshop, "though it could reach," Fernandez added, "is not the aim should be" because the idea is to prioritize those needs that can be more useful for people with disabilities ".
"The project aims to help disabled people to enable them to interact with a computer, but could also apply to any device, like a light switch," said the researcher Elche.
The basic technology employed in this project, funded by the Ministry of Science with 130,000 euros, is not novel, is already being applied to use the hearing devices, but it is their application to handling computers, "what makes This project is unique in the world. "
The interface that uses EEG signals (EEG), to detect what the intention of the person using evoked potentials, EEG signals corresponding to reflect an automatic response from the brain to external visual stimuli.
The next step of this project, as other researchers insured José Maria Azorín, is "check it out on people with different disabilities, and for now only been tested in healthy people and, not surprisingly, the project is dependent fact in mind.
Recalling that the investigation is in its second year of the three planned development, Azorin has stressed the need to "innovate" on this same system to "make it faster and easier to use."
"The signal is not good enough, because the electrode is on the surface of the head, half an inch above the signal and, furthermore, there are millions of neurons, which, by now, you can not be very specific orders, "specified Fernandez.
For now, the interface is not patented, "the idea is to make it available to everyone who needs it from the UMH, although there are companies interested in boosting, we welcome it," researchers have concluded.
This research is part of a research project granted by the Ministry of Science and Innovation, called 'control tele-robotic systems through advanced interfaces for Disabled People' in the brain that develop interfaces to control robotic devices.
