Interactive system and interactive device thereof

An interactive device adapted to communicate with a display device, the display device being configured to display an image thereon, said interactive device comprising:

• an image capturing unit operable to capture at least a part of the image displayed on the display device;
• a control unit coupled to said image capturing unit;
• a feedback unit coupled to and controlled by said control unit to produce a feedback output;
• and
• a signal transceivinq unit coupled to said control unit and configured to communicate with the display device,
• said control unit being operable to transmit information of said part of the image captured by said image capturing unit to the display device via said signal transceiving unit, said feedback output produced by said feedback unit being based on a feedback signal that is received from the display device and that corresponds to said part of the image captured by said image capturing unit.

An interactive device adapted to communicate with a display device, the display device being configured to display an image thereon, said interactive device comprising:

• an image capturing unit;
• a control unit coupled to said image capturing unit;
• a processor unit coupled to said control unit;
• and
• a signal transceiving unit coupled to said control unit and configured to communicate with the display device,
• said image capturing unit being operable to capture at least a part of the image displayed on the display device, said control unit being operable to control said processor unit to determine location of said interactive device relative to the image displayed on the display device based on said part of the image captured by said image capturing unit.
