Software uses brain scans to identify exactly what people are looking at

Researchers are a step closer to being able to read people’s thoughts after creating a computer program that can identify what someone is looking at using brain scans.

A team from Radboud University Nijmegen in the Netherlands used image and shape recognition software and a specially designed algorithm to assess changes in a person’s brain activity using functional magnetic resonance imaging (fMRI) technology.

During tests the scientists showed participants a series of letters and were able to identify exactly when, during the scan, they were looking at which letters.

Dutch researchers have created software that when used with brain scans can identify the shape and outline of what a person is looking at. During tests, scientists showed participants letters, pictured, and ran the changes that occurred in the brain after each letter was shown through a bespoke algorithm to identify them.

Dutch researchers used fMRI scans to zoom in on changes, pictured, in specific regions of the brain called voxels, in the occipital lobe. These voxels are around 2x2x2 millimetres big and the occipital lobe is the part of the brain which reacts to visual stimuli and processes what the eyes can see through the retina.
