A stylus for commanding by maneuvering is provided. The stylus includes a communication module for connecting with a computing device. The computing device is equipped with a touch sensitive panel for detecting the location of the stylus on or near the touch sensitive panel. The stylus includes at least one posture sensor; a memory for storing a maneuver database; and a stylus processor. The maneuver database store a plurality of maneuvers, each with associated one or more sets of moving vectors and an associated command. The stylus processor is configured to receive a moving trajectory from the posture sensor and to calculate one or more sets of moving vectors; based on the calculated one or more sets of moving vectors, finding the associated maneuver and the associated command in the maneuver database; and transmitting the command to the computing device via the communication module.
