Abstract

Disclosed are a correcting-free cursor tracking and aligning method and a correcting-free cursor tracking and aligning system. The method is suitable for the correcting-free cursor tracking and aligning system with an air mouse device and a calculating device which has an actual screen to display a cursor. The correcting-free cursor tracking and aligning method can announce a virtual screen of the air mouse device, and the virtual screen has an application screen corresponding to the actual screen. Only when a first axial coordinate value of a coordinate point of a virtual cursor directed by the air mouse device does not exceed a first axial border of the application screen or a second axial coordinate value of the coordinate point of the virtual cursor does not exceed a second axial border of the application screen, a cursor moving signal allowing the cursor to move on the actual screen can be generated.

Description

technical field [0001] The present invention relates to a cursor tracking alignment system, and in particular to a calibration-free cursor tracking alignment method and system thereof which can perform cursor tracking alignment without calibration. Background technique [0002] In recent years, due to the integration of Micro Electro Mechanical Systems (MEMS) technology and semiconductor technology, dynamic sensing elements tend to be smaller and more precise. Currently, dynamic sensor components such as gyroscopes and accelerometers are widely used in various air mouse devices. For example, the air mouse device can be implemented through smart remote control devices for home appliances, joystick devices for game consoles, pointing control devices for presentations, and handheld devices such as smart phones. [0003] However, when the user operates the traditional air mouse device in the traditional cursor tracking alignment system, the problem of cursor error may occur. P...
