associated window. When the computer allows the user to run
several programs simultaneously, he has access to several
windows simultaneously.
Simultaneous access can require the user to manipulate the
windows to access the different programs. Such manipulation
includes moving a window about the screen, changing the size
of a window, and minimizing a window into an icon.
The user typically manipulates a window by using a cursor
associated with a mouse to perform a "drag and drop"
operation. When the user wants to move a window, for example,
he moves the cursor to the window, depresses a button on the
mouse, "drags" the window to a location by moving the cursor
thereto, and "drops" the window by releasing the button. When
the user wants to resize a window, for another example, he
moves the cursor to an edge of the window, depresses the
button, moves the cursor to a position that approximates the
desired size of the window, and releases the button. Repeated
performance of the move and resize operations requires the
user to repeat mechanical muscle movement throughout the day.
Such repeated movements can produce carpal tunnel syndrome.
