The existing remote controllers are mostly infrared remote controllers, and in the using process, due to the technical limitation that infrared communication needs to be in the same direction, when remote control operation is caused, a user needs to aim the remote controllers at the receiver position to smoothly realize the remote control function, so that remote control action becomes inconvenient. Especially, when the infrared receiver is shielded by an object, the remote control function cannot be realized.
With the development of communication technology, the display content of the large-screen device can be projected into the small-screen device, and the small-screen device can control the large-screen device through touch operation. For example, after the smart television is connected with the mobile phone, the display content of the smart television can be projected to the mobile phone, and the mobile phone can control a program channel or a program playing progress through touch operation. However, when multiple mobile phones are connected to the same smart television at the same time, the smart television may be controlled by multiple users, and if the time interval between the touch operations of the multiple users is too short, or the touch operations are performed simultaneously, the smart television may respond to the touch instruction in a non-timely manner, and cause problems such as response disorder, which may affect the user experience.

Further, when the timer status bit is the first status bit, it is determined that the current timer has arrived. And when the timer status bit is the second status bit, determining that the current timer does not arrive. For example, a timer is set to count down for 3 seconds, and if the 3 seconds are over, that is, the timer arrives, the status bit is 0; otherwise the status bit is 1.

When the user performs a touch screen operation on the client of the control device 10, that is, in the synchronous frame on the touch APP 101, for example, the user slides upwards on the left side of the screen, the control device 10 correspondingly generates a first touch instruction "increase the brightness of the display screen" and sends the first touch instruction to the smart device 20 through the communicator 220.
Illustratively, the communicator 220 of the smart device 20 further looks at the time difference between the current touch instruction and the historical touch instruction after receiving the first touch instruction of "increase display screen brightness". In the embodiment of the present invention, when the number of the control devices connected to the intelligent device 20 is greater than 1, the intelligent device 20 determines whether a touch instruction has been successfully responded in a short time by checking the time difference, so as to avoid that the intelligent device 20 responds to a plurality of touch instructions from different control devices in a short time, and avoid the problem of response disorder.
In step 603, the smart device 20 responds to the first touch instruction.
Illustratively, the smart device 20 responds to the current "increase the brightness of the display screen" first touch command when the time difference is determined to be greater than or equal to the set threshold, that is, no touch command is responded in a short time. Further, the processor 254 in the controller 250 of the smart device 20 instructs the display 275 to execute a first touch command of "increase display screen brightness", increasing the brightness. In the implementation of the present invention, when the time difference is determined to be greater than or equal to the set threshold, the smart device 20 executes the first touch instruction, so as to respond to the user and improve the control efficiency.
In step 605, the smart device 20 does not respond to the first touch command.
Illustratively, when the smart device 20 determines that the control device is a different control device, it does not respond to the first touch instruction, and discards the touch instruction.
