Abstract
Pixel Data Access is an interprocess communication technique that enables
users of graphical user interfaces to automate certain tasks. By accessing
the contents of the display buffer, users can search for pixel representations
of interface elements, and then initiate actions such as mouse clicks and
keyboard entries. While this technique has limitations it offers users of
current systems some unusually powerful features that are especially appealing
in the area of end-user programming.
