Abstract

A technique is described whereby computer screen display window selection is controlled through the use of algorithms when one or more transparent windows obscure other windows. Detectability attributes are used in constant time consistency for both transparent and opaque windows. The concept is an improvement over previously-used window selection methods in that it avoids potentially costly searches during interaction with the user. (Image Omitted) The concept of transparent windows essentially pertains to windows which do not obscure the windows which they overlay. They allow the overlaid windows' contents to show through as if they were overlaid by a piece of glass, hence the term "transparent". An example of the transparency is as shown in Fig. 1.
