Abstract

Touch screen monitors are difficult to use because they often are personally customized to each user's characteristics. The resulting monitor is much easier for one user to employ, but more difficult for another. Promoting such a touch screen as a product can be difficult in front of an open audience.

Presentation Manager Touch Screen Indication

       Touch screen monitors are difficult to use because they
often are personally customized to each user's characteristics.  The
resulting monitor is much easier for one user to employ, but more
difficult for another. Promoting such a touch screen as a product can
be difficult in front of an open audience.

      In previous developments of touch screen devices, a pen was
created which alleviated the difference in finger coverage on the
touch screen.  The pen was thin enough to avoid covering the whole
area selected.  The thin pen was a partial solution, but its use was
bothersome to those users who had other devices to interact with.

      A program has been developed which defines to the IBM
Presentation Manager* how a Touch Monitor is to be used. Two
interrelated rules have been defined for Touch Screen interaction.
The first rule is when a finger touches the screen, the cursor arrow
will move with the finger, and any item which can accept a push for a
selection will be highlighted, indicating that the user is in the
selected area.  (The finger does have the problem of partially
covering areas for selection.) The second rule in selection is
performed by a "button-up" event.  Hence, the user can move the arrow
over an area and "lift off" after an indication has been given that
the area is selected.

      The two rules for a Touch Screen Monitor provide ease of use
and virtually remove the singularity...
