Abstract
A method and apparatus are provided for effecting an RFID-based finger input sensing system using a transmission line connected to at least two RFID tags, by analyzing a plurality of features relating to the number of spikes in the derivatives of the RSS, timing of maximum RSS and the spikes of the RSS derivatives, relative RSS magnitude between the at least two RFID tags, and increase/decrease trend of the RSS, thereby eliminating the need for calibration and training.
