Abstract
A screen magnification software feature that listens to internal messages within an operating system and automatically detects an input control coming into focus and sets a primary magnified viewport on that input control. As an end user interacts with the input control the software further listens for operating system messaging indicating a change in an output region responsive to the interaction with the input control. Upon detecting this output region change, a secondary magnified viewport is displays simultaneously with the primary magnified viewport on a graphic user interface, the focus staying within the primary magnified viewport. The end user has magnified views of both the control she is interacting with (e.g., a virtual calculator keypad of buttons) in the primary viewport and the output region (e.g., a text box showing the calculated result) in the secondary viewport.
