Abstract
Touch-based communication between users and various electronic devices is provided by encoding data onto the device's EMI. When the device is touched by a user, the data encoded EMI signal travels through their body and into a radio receiver worn by the user, such as via a wrist band. Results show that electronic primitives such as LEDs, buttons, I/O lines, LCD screens, motors and power supplies can be turned into radio transmitters capable of touch communication. Effective data rates range from 5.8 Kbps to 22 bit per image depending on the primitive used.
