Introduction During a dragging operation, the user moves
a mouse or trackball in order to position a cursor over an
object of interest. The user then presses a button and moves
to a new position while holding the button down. For a text-based
application such as word processing, this kind of dragging
operation may move all of the selected text from the initial
cursor position to the subsequent cursor position. The dragging
operation is cumbersome, especially when used with large graphic
displays. In such cases. the button must be held down for
a relatively long period of time while the mouse or trackball
is moved with precision over a large distance. A method of
simplifying the cumbersome dragging operation is needed.
Description To simplify the dragging operation, the use
of a sliding inset button is proposed. A small sliding inset
button is mounted in the mouse button. During the click operation,
the sliding inset button is in the rearward position. When
the finger presses the mouse button downward, the applied
force causes the mounting tab to bend. As a result, a switch
pad presses on an action pad. When the mouse button is released,
the mounting tab returns the mouse button to its original
position. During the dragging operation, the finger presses
on the mouse button and moves the sliding inset button forward.
As a result, a catch engages a recess in the mouse top and
fixes the mouse button in the depressed position. Slight pressing
of the mouse button results in the catch and the recess disengaging.
The sliding inset button can now be moved backward to return
the mouse button into the unlatched, original position. Thus,
a sliding inset button simplifies the dragging operation.
Additional information The proposed mechanically latching button has
a simple design.
