AI Can Now Detect How You Feel

( So, this is creepy. Scientists have reportedly developed new artificial intelligence technology that let robots detect human emotions using wireless signals.

Scientists and researchers from the Queen Mary University of London revealed a new neural network technology that can understand changes in heart rate to determine how somebody feels. A report from “Defense One” describes it as a new technology that could find use in a military environment.

The artificial intelligence was created by computer scientists who built the coding equivalent of biological neurons, allowing signals to be passed through the system. As the AI is used, the neural network can change, learning as it goes and understanding certain connections and nodes.

Confused yet?

The Daily Mail described the technology with an analogy.

“For example, given a set of cat pictures to study, a network can learn to pick out characteristic cat features on its own – and so tell them apart from other animals,” the outlet said.

The system has been in use for some time, with even Google using artificial intelligence to automatically determine what photographs are and filtering them into categories. It’s a technology that many people already use on their smartphones, and which is more advanced than you might think.

Queen Mary University researchers found that an interconnected computational system that is based loosely on the brain could be used to detect how humans are feeling. A series of participants were shown a range of videos designed to evoke different reactions and emotions.

Researchers fired radio waves at the participants and used an antenna to measure the waves that came back. The subtle movements made by individuals as they watched the videos were then analyzed by the neural network, where it began recognizing patterns. The radio waves helped the computer see breathing and heart rates, and it began connecting this information to emotions.

The experiment showed a 71% success rate for the artificial intelligence tech in recognizing the emotions of the participants, which means it was more than just chance.

While Defense One thinks it likely has a military use, some engineers have expressed their confidence that it could be used in more neuroscientific and psychological experiments with a view to helping people manage their emotional and physical health.

AI smartwatches, anybody?
