ABSTRACT:
The conventional keyboard is replaced by a virtual keyboard pattern on the computer screen by this invention. Selection of keystrokes is made by a mouse, or the like, positioning a cursor at a desired key for keyswitch selection. This manner of selection of pre-formed patterns available from the computer, such as alphanumeric characters and computer commands is particularly advantageous in a computer aided drafting and design system. Thus, notations and lettering need not be formulated by analog movement of the mouse, but can be selected digitally from the computer store by keyswitching. The resulting equipment therefor eliminates the conventional keyboard but not its operational advantages thereby permitting full computer operation with a mouse or the equivalent. Several features of the invention are provided for more convenient and more rapid operation, such as the replacement of the keyboard arrays as the computer changes modes of operation, and the placement of more frequently used keystrokes on the keyboard arrays for selection by minimized movements of the mouse.
