Remote control device, display system and associated display method

A remote control device, in communication with a display device, wherein the display device displays a display image, in which an indication path is pointed toward an intersection position, and an indication pattern is displayed at the intersection position, wherein an appearance of the indication pattern changes according to an information of vertical included angle, wherein the remote control device comprises:

• a housing, having a predetermined cross-section, wherein the indication path is extended from the housing;
• a gravity sensing unit, for sensing a vertical included angle between the predetermined cross-section and a vertical line to obtain the information of vertical included angle;
• and
• a transmission unit, electrically connected to the gravity sensing unit, for transmitting the information of vertical included angle to the display device.

A display method, applied between a remote control device and a display device that are in communication with each other, the display method comprising steps of:

• sensing a vertical included angle between a predetermined cross-section of the remote control device and a vertical line to obtain an information of vertical included angle, wherein an indication path is extended from the remote control device;
• transmitting the information of vertical included angle to the display device;
• and
• displaying a display image, wherein the indication path is pointed to an intersection position in the display image, an indication pattern is displayed at the intersection position, and an appearance of the indication pattern changes according to the information of vertical included angle.
