Abstract: A wireless controlling system including a smart ring and an identification program installed in a mobile device is disclosed. The ring includes an MCU, a six-axis accelerometer, a transmitting unit and a storage. The storage stores multiple gesture models respectively corresponding to different moving trajectories. When a user moves with the ring, the six-axis accelerometer continuously detects a set of moving signals of the ring. The MCU continuously determines whether the set of moving signals matches any moving trajectory of the gesture models. When a gesture model is matched, the MCU sends a gesture command corresponding to the matched gesture model to the mobile device through the transmitting unit. The mobile device analyzes the gesture command to obtain a corresponding operation command through the identification program, and the mobile device is being controlled to execute a corresponding function in accordance with the operation command.
