A control system is provided. The control system includes a ring device and a controller. The ring device includes an inertial measurement unit (IMU) sensor. The ring device is adapted to be worn on a finger of a user and the IMU sensor is configured to obtain sensor data. The controller is configured to receive the sensor data from the ring device and generate detection data based on the sensor data. The detection data is configured to indicate whether the ring device is rotated and whether the ring device is tapped. The controller is configured to perform a control operation in a virtual world displayed by the controller based on the detection data.
