Technical field
The present invention relates to the Digital Television human-computer interaction technology, relate in particular to a kind of based on sterically defined interactive television remote control.
Background technology
The traditional analog television of constantly popularizing in the whole world is under Digital Television conversion trend, television set promptly can provide interactive application and service with interactive mode to the user by video screen from originally only providing single TV programme playing function to develop into the multipurpose information service terminal that can respond man-machine interaction gradually.For adapting to mutual value-added service, the more requirement of Gao Gengxin has been proposed also the TV remote controller technology based on TV.
The technology and the thinking of many improvement TV remote controller were all proposed up to now, both at home and abroad.As the Chinese patent notification number is CN2086027 " hand type TV remote controller ", a kind of hand type TV remote controller that is used for channel selection is disclosed, by infrared transmitter, be installed in receiver, relay and motor in the housing, and belt pulley, belt, screw rod, pinch roller seat, pinch roller and locating rack are formed.Housing, belt pulley, belt, screw rod, pinch roller seat and pinch roller are installed in the channel selection button place of television set by locating rack.Infrared transmitter is a separate component, and after its signal that sends was received machine and receives, actuating motor by belt drives screw rod, nut, moved up and down nut, and the pinch roller on nut can be pressed a certain channel selection button and reach the purpose of channel selection.
The Chinese patent bulletin is CN101005564 " parallel television remote controller, remote control system and remote control circuit ", a kind of the have built-in micro-television screen and the remote controller of audio system are disclosed, this remote controller is supported the exchange of media between main video screen and the micro-television screen, and the exchange of related audio system.User interface on the remote controller allows the selection with channel checked of media guidance, so that show on the micro-television screen on main video screen and the remote controller.And can media guidance be downloaded to or be cached to remote controller by request, on the miniature screen on the remote controller, to show.On this remote controller, just can check and demonstration and the setting of managing video on the video screen of association, made things convenient for operation and selection.
Obviously, present TV remote controller technology, still based on the man-machine interaction mode of " upper and lower, left and right ", user's control operation complexity, and can not satisfy interactive application and demand for services that TV remote controller becomes increasingly complex, promptly can not form general remote controller space coordinates by space orientation technique feeds back in the video screen, can not the perceive motion acceleration, multidate informations such as angular speed, track feed back in the service of motion class interaction content, can not the perception human pulse, Human Physiology information such as blood pressure, blood fat and feeding back in the medical class interaction content service.Therefore, be difficult to support demand and realization based on the interaction content service of video screen and human-computer interaction.
