Technologies Interpret Mood from the Skin

Researchers have developed a way to interpret biological signals produced by the conductance of the skin. Using data obtained using a wrist-worn wearable sensor device that also includes an accelerometer to measure movement, the researchers’ system displays information in the form of colorful spiral graphics in real time on a smartphone as well as a recording of data for the wearer to interpret. Skin conductance is a measure of how much someone sweats, indicating their emotional reactions as well as physical reactions and is the basis for technologies such as lie detectors.
