Abstract

When using a software application, a small pop-up window sometimes appears on top of the current window. This pop-up window often contains a short message or requests the user to enter some information. By overlaying the user's current window, the pop-up window changes the user's current window. This change can confuse naive computer users. Naive computer users may wonder what happened to the information that was overlaid and whether the information is still there.

Pop-Up Window Shadow

      When using a software application, a small pop-up window
sometimes appears on top of the current window.  This pop-up window
often contains a short message or requests the user to enter some
information.  By overlaying the user's current window, the pop-up
window changes the user's current window. This change can confuse
naive computer users.  Naive computer users may wonder what happened
to the information that was overlaid and whether the information is
still there.

      This article describes a simple, unobtrusive way to make it
obvious that the pop-up window is overlaying, but not permanently
changing, the current window.  The pop-up window shadow is a dark,
preferably black, slightly offset, outline that runs along the bottom
and right borders of a pop-up window.  This shadow uses a concept
with which naive computer users are already familiar:  when one
object is on top of another object, the top object can cast a shadow
onto the bottom object without changing the bottom object.  A sample
popup window shadow is shown in the figure.
      The pop-up window shadow has the following features:
      o  Small -- To minimize the amount that the bottom window is
overlaid, the pop-up window shadow is only about one character in
width.
         Unobtrusive -- Since computer users in western cultures
expect window text to appear at the top, left corner of the window,
the pop-up window shadow appears unobtrusively alo...
