Abstract

A method of data entry using a touch display as the input mechanism. The following constraints had to be considered in the design. 1. Minimize the amount of alphabetic entry (as from a keyboard). 2. Maximize the use of direct manipulation by touching. 3. The touch targets must be large enough to accommodate large fingers. 4. Users who use the same touch application on a regular basis will learn target positions and start anticipating their responses by hovering their finger above where they anticipate the target to appear.

Use of Form Metaphor and Auto-Prompting to Simplify Field Entry on
Touchscreen

      A method of data entry using a touch display as the input
mechanism.  The following constraints had to be considered in the
design.
  1.  Minimize the amount of alphabetic entry (as from a keyboard).
  2.  Maximize the use of direct manipulation by touching.
  3.  The touch targets must be large enough to accommodate large
       fingers.
  4.  Users who use the same touch application on a regular basis
       will learn  target positions and start anticipating their
       responses by hovering their finger above where they
       anticipate the target to appear.

      Thus,  the  design  required  consistent placement, large touch
targets, and minimal touching for both initial entry and editing of
entry fields.

      The design solution incorporated the visual metaphor of a data
entry form.  The screen layout included data entry fields and
feedback area, and an input area (Fig. 1).  The input for the entry
fields could be either required or optional.  Optional fields are
displayed with a default entry.  If the field is required, the user
is prompted on the input side of the screen with the necessary input
control (i.e., numeric keypad, selection list, button options).  When
the selection is made or Enter is touched on the keypad, the entry is
reflected in the entry field in the feedback area (Figs. 2 and 3).
When all required fields...
