Disney’s Watch Can Tell What You’re Holding, Opening Up World of Self-Contained Interactivity
Using electromagnetic signature detection, the EMSense watch can unlock laptops or electronic office doors with a touch
The EMSense technology developed by Disney and Carnegie Mellon University detects small amounts of electromagnetic signals to identify what your body is in contact with. Using a clever hack, it works with objects that emit an EM signal (which is close to everything electrical or electromechanical we touch today).
Disney’s technology isn’t about new hardware or new tech, it’s about working with what’s already there. Many electromagnetic objects, like a laptop touchpad or a doorknob, emit signals that are too weak for any particular use until now. The EMSense measures these trace amount of EM signals that propagate through the human body. The patterns form this detections can then be compared to a library for identification.
