In the future your smartphone could be detecting your emotions. Researchers at the Massachusetts Institute of Technology have developed a device that can detect a person’s emotions by reading wireless signals bouncing off your body. The device detects a person’s emotion by sending wireless signals that measures the person’s heartbeat and sends it back to the device. It will be able to determine if a person is feeling sad, happy, angry or any other emotions. The device works like an electrocardiogram monitor but without needing a sensor on the body to measure heartbeats. Researchers say that the device is 87 percent accurate and believe that this device will be able to help help monitor and diagnose conditions like depression and anxiety in the future.
