Abstract: A mobile device, an action performing system and an action performing method can solve the problems such as inconvenient operation and ease of misoperation occurring in practicing action transfer with present multi-screen interaction technique. The mobile device includes: an executing unit, for performing an action of displaying an image and/or playing a sound; a processing unit, for acquiring optional information, determining whether to transfer the action to a fixed device based on the optional information, and transferring the action to the fixed device if the determination result is yes, otherwise not transferring the action, the optional information including a distance between the fixed device and the mobile device; and a first wireless communication unit, for enabling the mobile device to perform a first information exchange with the fixed device in a wireless manner, the first information exchange including sending information required for performing the action to the fixed device.

Abstract: The present invention provides a remote controller, a display device and a remote control display system. The remote controller comprises a control module and a transmitter module electrically connected to each other, wherein the remote controller is provided with at least five direction keys each corresponding to a different control direction, and when any one of the direction keys is pressed, the control module can control the transmitter module to transmit a direction remote control signal corresponding to the pressed direction key to a remotely controlled display device. The present invention can enable a corresponding object on the remotely controlled display device to move in more directions, thereby significantly simplifying operation steps required for carrying out moving or positioning operation through the remote controller.
