Scientists have been able to truly read human thinking with advanced computerized scanning technology and capture face images from the testers’ minds. If this technology is further refined, the police’s electronic facial recognition technology and even video recording of closed-circuit television will all be history as the police are able to get the true appearance of criminals directly from the victim’s brain.
This amazing technology has also brought new hope to people with disabilities who have speech problems and terrorists can not hide their massacre plans in the presence of law enforcement officials. Developed by neuroscientists at the University of Toronto in Canada, the new technology uses EEG monitoring equipment to gather people’s brain activity and reproduce the images they perceive.
Principal Investigator Dan Nemrodov said: “When we see something, our minds produce a mental state of mind, which is essentially a psychological impression that we can get through the brain with the help of electroencephalographic equipment What’s really exciting is that we are not reproducing the shapes, but the true look of a person and the many detailed visual features. ”
“We were able to recreate a person’s visual experience based on people’s brain activity, which brought us many possibilities,” said the researcher, “The technology unveils the content of our brain’s mind and gives us a Ways to explore and share what we perceive, remember, and imagine. “It also provides a way for people who can not communicate in languages.”
This technology not only reproduces a person’s perception from a neural basis, but also reproduces the content of their experiences and memories. The technique can also be applied to forensic applications by law enforcement authorities, and judicial officers can gather suspects’ information through witnesses instead of relying on verbal descriptions to obtain sketches.
During the study, researchers showed face images to testers connected to EEG devices. The testers ‘brain activity was recorded by the device, and the researchers then reproduced the digital image of the testers’ perceptions using a technique that was based on a machine learning algorithm.
Researchers have previously conducted similar tests with expensive MRI equipment, but EEG devices are cheaper, more portable and more practical. Researchers are now extending this technique to explore the possibility of getting more details from testers’ memories. The research funding comes from a new researcher’s prize at the Natural Sciences and Engineering Research Council of Canada (NSERC) and Conant.
