I want to implement a function. When a person approaches the computer, the infrared receiver is sensed and can automatically open the media player in the computer to automatically play a movie.

I'm doing web development in Java, and I don't know much about hardware. Can any friend give me a solution and how to implement it the easiest? Thanks!

There is an interface problem...

Communication between sensor and PC...

That is, after the sensor confirms the signal, how to inform the PC of the problem...

It can be serial, parallel, USB, Ethernet, etc.

I have only done serial port. Let's take a so-called solution...

Using the multi-process and speed advantages of PC and JAVA, use one process to monitor the communication port...

When a legal signal arrives, start the application...

Use a single-chip microcomputer with USB function (low speed is fine) to realize IR detection.After detecting the signal, the corresponding command is transmitted to the PC via USB, and the rest is solved by the program on the PC side.

Thank youironfistand5022219022for your suggestions, I have never touched this aspect before
There is still no clue to the specifics. What kind of knowledge is needed to realize such a function?

Regarding infrared devices, I don't know which ones are available on the market, what are their names, and what is their interface with PCs?
What I need is actually to get a response through infrared rays, and there is no need for complicated functions such as transmitting data through infrared rays.
If the MCU with USB function (with IR detection) mentioned by5022219022is available, there is no need to prepare infrared devices, right?

Should the PC program be implemented in assembly or in C language? (Consider calling the media player)

To detect the signal of the infrared sensor through the serial port, use the 7th pin of the serial port
When there is a signal, the PC will start the playback software
Very simple

Can you consider using a camera to trigger an event when the captured image changes?
