Patty Mace (Pattie Maes) and Cosmin Natalia (Nataliya Kosmyna) from the Massachusetts Institute of technology have developed a device that allows you to voice the images, which a person thinks, using the same working principle. This unit looks like the famous junction hat from movie “Harry Potter”. Reports Hvilya.
In order to implement such functionality in a real device, the engineers used a commercially available wearable EEG with 14 electrodes placed on different parts of the head.
As reported by the developers, the hat registers on the brain activity using electroencephalography and analyzes it with the help of a neural network to map patterns of activity with those that were recorded during calibration of the system.
The interfaces like brain-computer actively studied by scientists, mainly to assist patients with impaired motor functions. For example, using electroencephalography, some patients are able to walk or regain the use of your arms after a stroke.
At the heart of these methods lies the reading brain activity, detection of movements provided by the patient, and transfer appropriate commands to the electrodes connected to the muscles. However, the same principle can be used for other tasks.
Before starting work, the device needs to be calibrated. To do this, the user is shown pictures of various objects and actions, then he should present it. During this process, the device records the brain activity and associating it with the displayed objects or actions.
Hat determines the image that represents the person, and reads the response through the connected speaker.
The creators of the hat say that in the future they plan to use it as a tool to increase self-esteem in children while learning. According to them, the child will trust the hat, which “understands” what he’s thinking, and therefore will listen to its assessments and motivation.
We will remind, the first time scientists have connected the prosthetic hand to nerve endings with the result that the patient was able to feel the hand and even move it.
As reported by the portal “Znayu” user published a post about Harry Potter, which is able to turn the whole world fans of the magical universe.
Also “Znayu” wrote a foreign company develop a digital copy of a person that should replace it in the future. Technology will completely copy the personality of the person.
