Does anyone know how to do this?
Can you provide me any good links?

For the mouse, you place your hand over the top of the mouse. You may
either rest your hand on it or grasp it on the sides with your fingers.
Now move your hand around in a plane parallel to the ground.

What are you actually trying to do? What do you mean by "controlling the
mouse and keyboard?"

What I write is what I mean. I request that anyone who decides to respond
please refrain from "disagreeing" with something I didn't write in the first
place.

Sorry I was too concise for anyone to see what I was saying. I am talking about
simulating the actions of a human user with software. MS Windows has several OS
functions for this purpose. mouse_event(), keybd_event(), and SendInput(). I
want to know whether or not Mac OS has this same sort of feature, and what the
feature would be called.

It is called "GUI Scripting". It is part o Universal Access. It is off by
default. It is off on over 90% of all Macs. It is a security hole. It
can be enabled by the user on the "Universal Access" panel of System
Preferences by selecting the [] Enable Access for Assistive Devices.

In addition, there are USB driver kits that show you how to write virtual
keyboards and mice. Installing these requires getting the user to agree
to a security dialog.

There are system calls in Core Graphics to move the mouse that are not
restricted.

When you say USB kits do you mean that the keyboard and mouse can be
automatically controlled through using a USB hardware device, or can they be
controlled using software only?

Gregory Weston said, if you want the keys to go up and down, you'll need
to use your fingers or other hardware.

It is not that way on MS Windows, SendInput() simulates the actions of a human
user on both the Mouse and the Keyboard. SendInput() replaces the older
mouse_event() and keybd_event() system calls.

CGEventCreateMouseEvent()
CGEventCreateKeyboardEvent()
CGEventPost()
