Next gen. computers to mind read

Wed, 03 Oct 2007 22:15:34

Scientists say the next generation of computers will be ones that can read the mind and analyze its emotional and physical health.

Researchers with the Human Computer Interaction group at Tufts have recently come up with a computer which can tell whether the user is overworked, under-worked or not working at all.

The mind reading uses the technology called functional near-infrared spectroscopy (FNIRS) to measure the volume and oxygen level of the blood in and around the subject's brain.

According to a paper sent for Association of Computing Machinery symposium, the user wears a futuristic headband which sends light of the near-infrared spectrum into the head where it is absorbed by active, blood-filled tissues.

The headband then measures how much light was not absorbed, letting the computer gauge the metabolic demands that the brain is making.

Using the new technology, the particular area of the brain where the blood-flow change occurs, can be read. It will provide indications of the brain's metabolic changes by extension workload, which could be a trigger for emotions like frustration.
