Mind-Reading AI Tech That Recreates Images of Faces is now Here

By Rechelle Ann Fuertes February 27, 2018

A team of neuroscientists just created a mind-reading AI that can read minds with astounding accuracy.

Welcome to the 21st century! The era where science-fiction is rapidly turning into reality.
To add to the ever-growing list of inventions straight out of science fiction, psychologists from the University of Toronto Scarborough have recently developed a mind-reading AI technology.
According to reports, this artificial intelligence can recreate images seen by a human based on their brain activity collected by electroencephalogram (EEG) sensors.
Sound familiar?
Well, if you’re a fan of the sci-fi British anthology TV series Black Mirror, the AI-powered technology closely resembles the one featured in the episode Crocodile.
  In Crocodile, an insurance investigator peeks inside the head of potential witnesses using a button-like AI-powered device. The small device enables the investigator to see through the memories of the witnesses by projecting images to a separate display machine.
You probably get the picture now. It’s a highly sophisticated technology that we only see on our television screens. That was, until now.
By using advanced mapping techniques, the researchers were able to extract data from a person’s brain and convert it into useful information. That includes reconstructions of facial images in your head.

The Mind-Reading AI Technology

During the experiment, the researchers hooked up their subjects to an EEG brainwave-reading machine and were shown images of faces.
The team reportedly fed a neural network huge numbers of people’s faces and taught it to spot characteristics and patterns in each photo.
Then, the machine learned how to determine and distinguish these characteristics from one another. With this platform, it was then taught by the researchers to match it with brain activities recorded by the EEG scans while the subjects are looking at the faces. 
The mind-reading AI technology then analyzed the information gathered from the experiment and used it to recreate the images stored in the subjects’ minds digitally.
“When we see something, our brain creates a mental percept, which is essentially a mental impression of that thing. We were able to capture this percept using EEG to get a direct illustration of what’s happening in the brain during this process,” Dan Nemrodov, a postdoctoral fellow at the University of Toronto Scarborough, said.
This is not the first time that scientists have used neuroimaging techniques to reconstruct images based on visual stimuli. However, this is the first time that the images were created using EEG data. Previous studies were conducted using functional MRI technology which measures activities in the brain through blood flow changes.
Using EEG to recreate digital images based on brain activities is known to be far more portable, cost-efficient, and can produce greater levels of detail in milliseconds.

What are the Applications of This Mind-Reading AI?

The researchers believe that their mind-reading AI could one day be used in law enforcement to provide more accurate eyewitness reports about potential suspects’ semblance. To date, most of this suspected criminal information is still being relayed to sketch artists through verbal descriptions.
It might also be used to help people with verbal communication difficulties by visually reconstructing their thoughts at any given time. This may include memories and imagination to enable them to better express themselves.
The mind-reading AI is, naturally, not as sophisticated as the one showcased in Black Mirror. However, with more developments, the researchers believe that it could one day reach memories hidden inside our brains and play them like a video.
The researchers are hoping to improve their work and move beyond faces to explore the possibility of accurately recreating images of other objects. The team’s study was published in the journal eNeuro.

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke...

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that th...

New ATM's: withdraw money with veins in your finger

New cash machines: withdraw money with veins in your finger Cash machine technology that reads the pattern of finger veins is already available in Japan and Poland   By Telegraph Reporters 6:59PM BST 15 May 2014 Cash machines could soon be installed with devices that identify customers by reading the veins in their fingers. The technology is already being rolled out in Poland, where 1,730 cash machines will this year be installed with readers, negating the need for a debit card and Pin. Developed by Hitachi, the Japanese electronics firm, the machines read the patterns of the veins just below the surface of the skin on your finger using infra-red sensors. The light is partially absorbed by haemoglobin in the veins to capture a unique finger vein pattern profile, which is matched to a profile. The technology is used by Japanese banks and also in Turkey, offering “groundbreaking levels of accuracy and speed of authentication”, Hitachi said, which in t...
