I would assume that you would need to use a mouse recording software program and record the mouse moving across the screen, preferably in a straight line. Then you would need to rig some kind of button that causes the recorded mouse movement to play and the camera to start recording at the same time. The camera and computer would each obviously have different signal delays before they each started their assigned task, but you could treat the camera as a static variable, I guess.
To create the button to start the test, you would also need to solder wires running to the keyboard and camera PCB, and probably a tripod for the camera too.
Is what I just described correct? Or is there an easier way to do this, because I don't really see one.
You would also have to assume keyboard and mouse input lag are both affected equally by any variable you may test, which may or may not be the case. You might have to solder wires to the mouse left click button instead of the keyboard to create the button that starts the test and gets the mouse playback + camera going at same time.
