At what point, and how, does computer hardware touch/move/influence the software?
In: Technology
Almost immediately, for most hardware.
Take an optical mouse, for example. It’s shining a light down at your desk and measuring the reflection. As you move it ever-so-slightly, the pattern in the reflection changes, and there’s an onboard chip (with software on it!) that converts the changing electrical signals into digital information. That information is sent to the computer, where it’s handled by all sorts of other software, depending on if you’re just moving a mouse or playing Call of Duty or something.
