uinput is a user level input subsystem. Basically it is a linux kernel module that allows to handle the input subsystem from user land

uinput is a user level input subsystem. Basically it is a kernel module that allows to handle the input subsystem from userspace. It can be used to create and to handle input devices from an application. It creates a character device in /dev/input directory. The device is a virtual interface, it doesn't belong to a physical device.

Once the uinput module is installed (via modprobe or insmod), a character device is created, named as /dev/input/uinput (or /dev/uinput on some systems). This device represents the interface between the application and the kernel input subsystem.
