Automotive Diagnostic Screen Cursor Movement

       This article describes a technique which enables a user
to easily select a desired button from an automotive technician
terminal diagnostic screen using a remote keypad with one hand.

      In the automotive diagnostic environment, a user friendly
interface to the diagnostic equipment is required so as not to deter
the attention of the automotive technicians from their task.  Remote
entry to a diagnostic screen can be accomplished in many ways.  A
software means to provide remote data entry which does not hinder a
technician's performance is disclosed herein.

      Cursor Movement Keys In the technique disclosed herein, the
cursor movement keys allow the user to change the active button to
the one above, below, to the right of, or to the left of, the
currently active button.  The rules for movement are described below.
1.   Up Cursor
      Depressing this key will cause the button nearest in distance
and above the currently active button to become visually and
functionally marked as the active button.  Further, the previously
active button will be "de-activated".
      If a conflict arises between two buttons being equidistant from
the active button, the button to the
      left will become the new active button.
2.   Down Cursor
      Depressing this key will cause the button nearest in distance
and below the currently active button to become visually and
functionally marked as the active button.  The previously active
button will be "de-activiated".
      If a conflict arises between two buttons being equidistant from
the active button, the button to the left will become the active
button.
3.   Left Cursor
      Depressing this key will cause the button nearest in distance
and to the left of the currently active button to become visually and
functionally marked as the active button.  The previously active
button will be "de-activated".
      If a conflict arises between two buttons being equidistant from
the active button, the upper button will become the new active
button.
4.   Right Cursor
      Depressing this key will cause the button nearest in distance
and to the right of the currently active button to become visually
and functionally marked as the active button.  The previously active
button will be "de-activated".
      If a conflict arises between two buttons being equidistant from
the active button, the upper button will become the new active
button.

      The remote keypad consists of fifteen definable keys in a 3 x 5
matrix.  For cursor control entry, a template is overlaid on the
keypad to define four direction arrow keys and an ENTER key, as
illustrated in Fig. 1.  During a diagnostic application, buttons are
displayed on the technician terminal screen for touch entry.  The
function of this device is to allow the user to simulate a button
touch, without physically touching the technician termi...
