MIND READING TECHNOLOGY – A group of Scientists from the Toyohashi University of Technology in Japan has recently come up with a mind-blowing innovation; a ‘mind-reading technology’ that can foretell a person’s thoughts through analysis of the person’s brainwaves. The technology can recognize the numbers zero to nine with 90% accuracy using electroencephalogram (EEG) readings.

It can also recognize 18 of Japanese monosyllables from EEG signals with 60% accuracy. With this, the possibility of an EEG-activated typewriter is foreseeable. The research group collected EEG data of subjects speaking Japanese digits and monosyllables then conducted a digit and monosyllable recognition experiments.

WHAT HAPPENED BEFORE MIND READING TECHNOLOGY WAS DESIGNED

Before this new innovation, speech decoding via EEG signals has been cut short by a lack of data to allow the use of powerful algorithms based on deep learning or other types of machine learning. Through this innovation, a new framework that can achieve high performance with a small training dataset has been developed based on holistic pattern recognition using category theory, or composite mapping, a process by which a dual space, a tensor space including exterior algebra are introduced.

During the experiment to detect for spoken digit recognition from EEG signals, a high accuracy rate of 90% recognition was achieved. Through the experiment of 18 different types of Japanese monosyllable recognition a whopping 61% accuracy was achieved, outperforming previous research efforts. Humans have sufficient intelligibility of sentences with an 80% monosyllable recognition rate.
Researchers aim to develop a brain-computer interface that recognizes unvoiced speech. This technology may enable handicapped people who have lost the ability of voice communication to speak once again. In the future, the group plans to develop a device which they envisage will be easily operated with less electrodes and connected to smartphones within the next five years. This technology has shown promising signs and we are optimistic that one day it may allow speech-impaired people to communicate.
