摘要

The interface has keyboard with keys for receiving a specific command (CS), digit, letters or symbols relative to an input. The keys alternatively receive different colors (C1, C2), and the command initializes selection of arbitrary object on a screen. A keystroke of one of the keys initiates the selection of selectable object (OS) formed from a color image converts the image into black and white image (INB) and places a partial transparent selection indicator (IS) on the image. The object receives a direction indicator indicating a direction in which the key is found relative to the object.
