Handheld controller and method of controlling a controlled object by detecting a movement of a handheld controller

Abstract

The present invention discloses a method of controlling a controlled object by detecting a movement of a handheld controller, wherein the handheld controller comprises a central processing unit, a sensor, and a database, wherein the sensor is operated to detect the movement of the handheld controller, and the database is applied to store correction parameters. First, the sensor is applied to detect a movement of the handheld controller, to generate a signal, and to transfer the signal to the central processing unit, wherein the signal contains coordinates of the movement in a first coordinate system. After applying the central processing unit to send a request to the database to inquire a corresponding correction parameter of said signal, the database is applied to send the correction parameter to the central processing unit. Thereafter, the central processing unit is applied to generate a controlling command by multiplying the correction parameter to the signal, wherein the controlling command comprises coordinates in a second coordinate system. After that, the controlling command is transferred to the controlled object to direct the controlled object to move in the second coordinate system in accordance with the controlling command.
