SideSwipe System Enables Gesture-Controlled Phones

SideSwipe System Enables Gesture-Controlled Phones
Sep-17-14
By taking advantage of a mobile phone's GSM signal, researchers have created a SideSwipe system that allows users to control their phones without needing to touch them at all.

The prototype system uses four antenna elements and an algorithm to convert the "bursty reflected GSM pulses" into a constant signal that can then be used to for gesture recognition. The antennas, each one with a different radiation pattern, were placed at the edges of the PCB board and connected to RF power detectors at the center of the board. A ground place installed on the back of the PCB also helps to exaggerate the antennas' signal differences. Performing a gesture within the antennas' range causes different signal fluctuations that can be used to interpret the specific motion into a command.

According to the team, 14 gestures can be recognized with 87.2 percent accuracy.
