Background technique

With the rapid development of science and technology and the pursuit of a higher quality of life, many electronic products have been developed. In order to maximize the performance of electronic products, various remote controls with remote functions have emerged as the times require. But today's remote control is only improved on the transmission signal, and the remote control has no other functions. Obviously, the basic functions of the remote control can no longer meet the needs of modern people in electronic products, and the remote control can only control However, with the advent of the Information Appliance (IA) era, subsequent TV screens are all designed to have a variety of input interfaces, which can be used for various input devices (such as laser disc players, video recorders, etc.) , video camera, cable TV receiver or digital TV receiver, etc.) and a processing device (such as a computer host) are connected and used, so that the input device and the processing device can share a screen, reducing the problem of occupying space and displaying, but the remote control of the input device It is very different from the keyboard of the processing device, because the remote control of the general input device only has multiple function keys (such as volume switching, channel selection switching, playback or fast forwarding, etc.), while the keyboard of the processing device must be available or a keyboard for inputting characters, numbers, symbols, etc., and a mouse for cursor movement and selection.

Therefore, when the input device and the processing device share the same screen, because the remote controller cannot simultaneously input characters, numbers or symbols, and move the cursor to select functions, a situation occurs where the remote controller, mouse and keyboard are placed on the desktop respectively, which in turn causes Inconvenience in use.

However, the general mouse and keyboard are wired and need to be connected to the processing device through a transmission line. However, the length of the transmission line is limited, so the distance between the user and the processing device cannot be adjusted to a longer distance. If the wireless mouse and keyboard are used, they will increase the cost of use for consumers because they are expensive.
