Abstract
Innovative Human Machine Interface (HMI) technologies are fundamentally reshaping the way people live, entertain and work. Passive RFID tags, benefiting from its wireless, inexpensive and battery-free sensing ability, are gradually being applied in new-style interaction interfaces, ranging from virtual touch screen to 3D mouse. Inspired by these glittering interfaces, this paper presents TagController, a universal wireless and battery-free remote controller with two types of interactive actions: press and motion. The key insight behind is that fine-grained phase information extracted from RF signals is capable of perceiving various actions when people operate the battery-free remote controller. TagController can recognize 10 actions without any training or prestored profiles by executing a sequence of functional components, i.e. preprocessor, action detector and action recognizer. We have implemented TagController with Commercial Off-The-Shelf (COTS) RFID devices and conducted substantial experiments in different scenarios. The results demonstrate that TagController can achieve an average recognition accuracy of 95.8% and 94.3% in the scenarios of one and two remote controllers, respectively, which promises its feasibility and robustness.
