Abstract

Disclosed is a method for entering alphanumeric characters using three keys on an operator console. A scrolling keyboard allows the user to select each character of the value from a scroll field, which is a menu of single characters and edit operations. By scrolling to each desired character and selecting it, a user can build an alphanumeric string. Since the menu also contains editing operations, it is also possible to edit the alphanumeric value using the same technique.

Scrolling Keyboard for Three Key Input of Alphanumeric Characters

      Disclosed is a method for entering alphanumeric characters
using three keys on an operator console.  A scrolling keyboard allows
the user to select each character of the value from a scroll field,
which is a menu of single characters and edit operations.  By
scrolling to each desired character and selecting it, a user can
build an alphanumeric string.  Since the menu also contains editing
operations, it is also possible to edit the alphanumeric value using
the same technique.

      Many parameters required for configuration of an advanced
function printer require the input of multiple alphanumeric
characters.  These parameters include, but are not limited to,
Internet Protocol addresses, Logical Unit names, multi-digit numeric
values, and  user-defined names.  High end printers use a full screen
display to present a soft keyboard from which the user enters the
values.  But for  low-end and some midrange printers, the cost of
including a full-screen  display or even a hardware keyboard could
reduce a printer's cost competitive advantage.

      This method for entry of alphanumeric characters uses only
three keys on the operator console.  The Figure depicts an operator
console with a small text display (1) and three keys; one key is an
"ENTER" key (2) and the other two (3,4) are for scrolling up and down
through a menu (5) of single characters and edit operations.  Since
the bottom of the menu wraps back to the top, one of the scroll keys
could be eliminated, but this would allow the user to scroll in only
one direction.

      The user accesses the keyboard by navigating to the display of
the current value of the parameter.  If a value has previously been
set for the parameter, the display shows the value followed by the
scroll field containing the edit operation "OK".  If no value has
been set for  the item, the display shows only the scroll field
containing "OK".

      The choices in the scroll field include the appropriate
character set for the value and a set of edit operations.  The user
scrolls the content of the field thro...
