Intel demos software that reads your mind

At Intel's Tech Heaven event in Manhattan on Wednesday, the company demonstrated software under development that can tell--under very controlled circumstances--what a person is thinking by reading brain waves. The chipmaker has been working with Carnegie Mellon University and the University of Pittsburgh to develop software and an interface to convert brain waves scanned from MRIs into something recognizable by computers.

Though still in the early research stages, the technology looks promising to researchers. In a preliminary test conducted by Intel Labs senior researcher Dean Pomerleau, the system scanned a person's brain to record its activity while showing the person certain words, specifically concrete objects like "barn" and "house" and "screwdriver."

'Mind-reading' brain scan software debuts

The Human Brain demo is a joint project between Intel, Carnegie Mellon University and the University of Pittsburgh to allow thought-based user interfaces.

The software analyses functional MRI scans to determine what parts of a person's brain is being activated as he or she thinks. In tests, it guessed with 90 per cent accuracy which of two words a person was thinking about, said Intel Labs researcher Dean Pomerleau.

Eventually, the technology could help the severely physically disabled to communicate. And Pomerleau sees it as an early step toward one day being able to control technology with our minds.

Brain's Codes for Noun Meanings

Identifying Thoughts Through Brain Codes Leads To Deciphering the Brain's Dictionary

"In effect, we discovered how the brain's dictionary is organized," said Just, the D.O. Hebb Professor of Psychology and director of the Center for Cognitive Brain Imaging. "It isn't alphabetical or ordered by the sizes of objects or their colors. It's through the three basic features that the brain uses to define common nouns like apartment, hammer and carrot."

As the researchers report today in the journal PLoS One, the three codes or factors concern basic human fundamentals: (1) how you physically interact with the object (how you hold it, kick it, twist it, etc.); (2) how it is related to eating (biting, sipping, tasting, swallowing); and (3) how it is related to shelter or enclosure. The three factors, each coded in three to five different locations in the brain, were found by a computer algorithm that searched for commonalities among brain areas in how participants responded to 60 different nouns describing physical objects. For example, the word apartment evoked high activation in the five areas that code shelter-related words.

In the case of hammer, the motor cortex was the brain area activated to code the physical interaction. "To the brain, a key part of the meaning of hammer is how you hold it, and it is the sensory-motor cortex that represents 'hammer holding,'" said Cherkassky, who has a background in both computer science and neuroscience.

Computer Uses Brain Scans to Read Minds

Associate professor of psychology Jack Gallant and two researchers, Kendrick Kay and Thomas Naselaris, first trained a computer program to recognize which of a set of 1,750 photos Kay and Naselaris were looking at while their brains were scanned by an MRI machine of the sort ordinarily used in hospitals.

The goal of the Gallant Lab is to understand the structure and function of the human visual system at a quantitative, computational level, and to build models that accurately predict how the brain will respond during natural vision. Predictive models of brain activity are the gold standard of computational neuroscience, and are critical for the long-term advancement of neuroscience and medicine.

Scientists move a step closer to mind-reading

Scientists have developed a method for reading a person's mind using brain scans.

Once it has been trained on an individual subject's thoughts, the computer model can analyse new brain scan images and work out which noun a person is thinking about - even with words that the model has never encountered before.

The model is based on the way nouns are associated in the brain with verbs such as see, hear, listen and taste. The research will inevitably raise fears that scientists could soon be able to read a person's mind without them realising.

How Technology May Soon "Read" Your Mind

The technology that is transforming what once was science fiction into just plain science is a specialized use of MRI scanning called "functional MRI," fMRI for short. It makes it possible to see what's going on inside the brain while people are thinking.

"You know, every time I walk into that scanner room and I see the person's brain appear on the screen, when I see those patterns, it is just incredible, unthinkable," neuroscientist Marcel Just told Stahl.

He calls it "thought identification."

Predicts Brain Activation Patterns for Thousands of Concrete Nouns

The team, led by computer scientist Tom M. Mitchell and cognitive neuroscientist Marcel Just, constructed the computational model by using fMRI activation patterns for 60 concrete nouns and by statistically analyzing a set of texts totaling more than a trillion words, called a text corpus. The computer model combines this information about how words are used in text to predict the activation patterns for thousands of concrete nouns contained in the text corpus with accuracies significantly greater than chance.

MALINTENT Mind Reading Security Scanning

Homeland Security is testing the next generation of security screening. The system, called MALINTENT, searches for non-verbal cues of fear or nervosity. It has a series of sensors that read body temperature, heart rate and respiration for unconscious signals, invisible to the naked eye.

Anxiety-detectingmachines could spot terrorists

A scene from the airport of the future: A man's pulse races as he walks through a checkpoint. His quickenedheart rate and heavier breathing set off an alarm. A machine senses his skin temperature jumping. Screeners move in to question him.
Signs of a terrorist? Or simply a passenger nervous about a cross-country flight?It may seem Orwellian, but on Thursday, the Homeland Security Department showed off an early version of physiological screeners that could spot terrorists. The department's research division is years from using the machines in an airport or an office building— if they even work at all. But officials believe the idea could transform security by doing a bio scan to spot dangerous people.

'MIND READING' SCANNER TESTED IN US
A "mind-reading" security scanner which screens the person, rather than their bags, is being tested in the US.

The Malintent system searches the body for non-verbal cues that predict whether the person intends to cause any harm to fellow passengers.

It uses a series of sensors and scans to detect temperature, heart rate and respiration as passengers walk through an archway - and could also cut airport queues. The system is also designed to be able to distinguish between a rushed, stressed and sweaty passenger, and a terrorist.

Brain Scans Let Computer 'Read' Visual Activity

Scientists have developed a computerized mind-reading technique which lets them accurately predict the images that people are looking at by using scanners to study brain activity.

Scary or sensational? A machine that can look into the mind | Science | The Guardian

The process relies on functional MRI to scan the brain for activity information related to the viewing of a chosen set of images. A computer database of brain activity-image links is then created, so that future viewings can be deduced based solely on an analysis of fresh fMRI patterns.

"We're not mind-reading," explained study co-author Jack L. Gallant, an associate professor in the department of psychology at the Helen Wills Neuroscience Institute at the University of California, Berkeley. "We're not reconstructing images of what people see or think. We can't do that yet, although it should be possible in principle."

A new research led by Gregor Domes at the University of Germany shows how oxytocin is involved in reading the others’ mind.

Oxytocin appears to ease the processing of social information received through two sensory pathways: hearing and vision. This hormone also was found to regulate stress and fear reactivity, explaining the theory of mind by decreasing the social anxiety accompanying many social encounters, an acute symptom in autism.

The hormone that helps you read minds

We've long accepted that hormones can make you amorous, aggressive, or erratic. But lately neuroscience has been abuzz with evidence that the hormone oxytocin -- which also acts as a neuromodulator -- can enhance at least one cognitive power: the ability to understand the gist of what others are thinking.

Microsoft's mind reading patent -- The future of advertising?

The art of predicting customer behaviour

In August 2007, software giant Microsoft filed a patent application for a system that would allow it to access thoughts. The patent describes pattern-recognition techniques that can be applied to electroencephalograph (EEG) signals – a measure of electrical activity in the brain – to determine what cognitive state the subject is in.
[...]
For one thing, its presence in the computer games market opens up intriguing possibilities: it could use brainwaves as a control mechanism.

There are other possibilities too. Microsoft has an avowed commitment to taking on search engine giant Google in the lucrative online advertising market. Now that is one area where a little mind reading could go a very long way.
