EMI Spy
Harnessing Electromagnetic Interference for Low-Cost, Rapid Prototyping of Proxemic Interaction


EMI Spy is a low-cost tool for proxemic user interaction with displays. EMI Spy captures electromagnetic interference and delivers the signal to a user’s mobile device or PC through the device’s audio input or over Bluetooth. Users are able to train the system in less than 1 second to recognize displays. The combination of a low cost EM logger and an open source machine learning tool kit allows developers to quickly prototype proxemic, touch-to-connect, and gestural interaction.
