Researchers are working on a system that reads the magnetic fields of the brain. It is planned that it will make it easier for people with disabilities to work at the computer.
Today, there are systems that are able to recognize the intentions of a user with disabilities by looking.
However, they cannot distinguish between intentional and involuntary gaze delays that occur, for example, when the user wants to look at something.
Researchers at MSUPE are creating a control system that will be able to determine if gaze delay is intentional or involuntary.
The new system works by distinguishing between brain signals that arise when performing certain mental actions; BCI allows you to give commands to a computer literally with the help of thought.
To do this, the user only needs to deliberately hold his gaze, and this very action, according to scientists, already changes the pattern of brain signals so that it is possible to recognize the desire not only to focus on that, but to click on the object.
The accuracy of determining what users want to click is not yet sufficient for immediate implementation of the technology. This is due to the fact that during the experiment it has not yet been possible to write enough data to train neural networks. This is a common problem when classifying brain signals by deep artificial neural networks. We are currently working on expanding our MEG data sample.Anastasia Ovchinnikova, Senior Researcher, MEG Center, MGPPU
