Hello there,

I am new to OpenCV and would like to know whether it can be used to detect keyboard inputs entered by the user.

I am planning to write a software that will be platform independent and this software should be able to get all User inputs on the hardware/software keyboard.

Is this possible using OpenCV?

Well, you can take a look at cv::waitKey

It will wait for a key during a delay amount of time (that you pass as a parameter) and will return an int value representing the key that has been pressed or an error value if no key was pressed.

It is quite basic, but it fulfills its purpose. Depending on what your purpose is you might need something more advance other than what OpenCV provides on this subject.
