Look at the back of your wrist and the WristPad will reveal itself (your thumb will be pointing towards you). It is a virtual tablet that provides lots of useful functions with a familiar flat-screen interface (mostly).
The Home Screen shows an array of buttons that will open the main screens.
These screens and how to use them are described later in context.
Use the back button to go back to the Home Screen:
You can grab one of the handles at the edge of the WristPad to detach a screen and drag it somewhere in your work area. To get rid of the screen, use the Destroyer.
