Have you ever wished your wearable devices could detect the objects you touch? EM-Sense can make that happen. As explained on DisneyResearchHub, most electrical objects emit small amounts of EM noise during regular operation that propagate through the user’s body when touched. EM-Sense uses a “software-defined radio” to detect and classify these signals in real-time for on-touch object detection.
The above video shows a smartwatch solution used for object detection. You are going to be able to do more with your smart devices when they can detect what you are touching. More information is available here.
