MIT Scientists Use Radio Waves To Sense Human Emotions (cnn.com)
An anonymous reader quotes a report from CNNMoney: Researchers at the MIT Computer Science and Artificial Intelligence Laboratory have developed a device that uses radio waves to detect whether someone is happy, sad, angry or excited. The breakthrough makes it easier to accomplish what scientists have tried to do for years with machines: sense human emotions. The researchers believe tracking a person's feelings is a step toward improving their overall emotional well-being. The technology isn't invasive; it works in the background without a person having to do anything, like wearing a device. The device called EQ-Radio, which was detailed in a paper published online Tuesday, resembles a shoebox, as of now. It works by bouncing wireless signals off a person. These signals are impacted by motion, such as breathing and heartbeats. When the heart pumps blood, a force is exerted onto our bodies, and the skin vibrates ever so slightly. After the radio waves are impacted by these vibrations, they return to the device. A computer then analyzes the signals to identify changes in heartbeat and breathing. The researchers demonstrated their system detects emotions on par with an electrocardiogram (EKG), a common wearable device medical professionals use to monitor the human heart. The machine's analysis of the radio waves relies on artificial intelligence, which learns how various heartbeats indicate certain emotions. As a part of the testing, the machine bounced radio waves off actors who recreated a range of emotions. The more emotions the machine experienced, the better it identified what signals, such as a fast heartbeat, gave away their true feelings. By monitoring radio waves reflected off people who are happy, the machine is exposed to certain signs -- such as heart rate or a type of breathing -- associated with being in good spirits.
I've seen another technology that can track eyes to measure dilation of pupils, heart rate from changes in skin color on the face, as well as breathing. A bit more to estimate body temperature from the infrared. I wonder if it is possible to measure blood pressure, not just that blood pressure falls and rises but something like those inflatable cuffs, without touching the person.
Measuring emotional response from questioning certainly has benefits for a police interrogator, especially if that detective's job is to find out if the suspect is human. I can see this as useful to quickly and easily measure a person's health. Problems with breathing while asleep would be easier with this machine. Put it at the entrance to a hospital and set certain limits on where it might flag someone for more attention. Not to replace more traditional diagnostic tools but to augment it.
If this could allow for removing some of the wires and such from a patient in a hospital and make them more comfortable. The emotional state stuff was already there before, they just automated it a bit more. Only then it was called a polygraph.
I am armed because I am free. I am free because I am armed.
Greetings, citizen! Your personal stress level appears to be elevated. To ensure a more harmonious life experience and enhance your calm, please report to the nearest behavioral modification center. Thank you for your cooperation, and have a joy-joy day.
I'm sorry, but your opinion seems to be wrong.
Ultimately this will just be another augment to automated monitoring, for use in any place where there is benefit to knowing people's emotions but a cost associated with having a human watch them all the time.
Like the TSA security check points at airports?
The TSA already tries to do behavioral profiling. I could see them jumping all over this as the latest magic cure-all to make up for the incompetence of their screeners who miss 95% of the things they're supposed to be watching for.
