Form of UI
From CS 160 Fall 2008
At least part of your game should have a conventional UI: a home screen, screens for entering player information, configuration options etc. You should include those sketches in your design.
Also include sketches of game screens and any on-screen control widgets that your game uses.
Many games will also use a direct mapping from the input device to game actions. Input devices include the keyboard, mouse, game controllers, cell phones and possibly other more exotic devices. These mappings are part of the UI design, in fact the main part since most game play uses them. You should describe the mappings you plan to use and the contexts where those mappings hold.
