New technology promises to wirelessly read human emotion

Computer scientists have developed a new technique to measure human emotions wirelessly. CBC Radio technology columnist Dan Misener explains how. In the past, this has been done with electrocardiography (ECG) monitors -- electrodes strapped to the body. But a team at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) has built a device that can do this without wires. They call it EQ-Radio, and in a lot of ways, the device is similar to a Wi-Fi router.
