New York: If you want to read some bodies emotions then here is a gadget which actually detect humans emotions. An MIT engineer has developed a wristband with significant potential to recognize changes in human emotions, the brain as well as behavior.
This wearable technology has an automated machine learning method that can detect compulsive seizures by combining measures of electro dermal activity on the wrist with measures of motion through a sweat response.
As told by Rosalind Picard, engineer and researcher at Massachusetts Institute of Technology “The skin is purely innervated by the sympathetic branch of the autonomic nervous system.” Sympathetic activation occurs when experiencing excitement or stress, whether physical, emotional or cognitive.
Another researcher, Picard added “We can observe increases in sympathetic brain activation by monitoring subtle electrical changes across the surface of the skin.
When some regions of the brain, such as those involved with anxiety, pain, stress and memory are activated during a seizure, they can elicit patterns of electrical changes in the skin.
The wrist-worn detector is now more than 96 per cent accurate for detecting convulsive seizures.
While the researchers have not demonstrated detection of non-convulsive seizures, 42 percent to 86 percent of non-convulsive, complex partial seizures also have significant electro dermal responses, the researchers said, in the paper presented at the American Pain Society Annual Scientific Meeting in Pennsylvania.
In addition, other clinical applications for wristband electro dermal monitoring include anxiety, mood and stress monitoring and measuring analgesic responses.
Picard said. “We know that pain intensify anxiety and stress and we are doing more studies to determine how reductions in anxiety and stress could indicate a pain-reliever response activated by a pain management therapy.”
