Recently, Carnegie Mellon University and Disney Research developed a new technology that could allow smartwatches to recognize what objects users are touching.
“The technique, called EM-Sense, takes advantage of the body’s natural electrical conductivity to detect whether a person is touching an electrical or electromechanical device and, based on the distinctive electromagnetic noise emitted by such devices, automatically identify the object,” Phys.org reported.
“EM-Sense is able to differentiate between scores of objects based on the ambient electromagnetic noise they emit, so objects need not be modified or have RFID tags for the technique to work,” Phys.org added.
According to Gierad Laput, a Ph.D. student in Carnegie Mellon’s Human-Computer Interaction Institute (HCII), a smartwatch would provide the perfect platform, because it has contact with the skin and also houses a highly capable computer for deciphering signals and running apps.
