Abstract

Disclosed is a method of generating a double-click event when a pen is used as an input device. The method uses not only button-down events but also mouse-movement events to generate a double-click event. The method uses the number of mouse-movement events generated between two consecutive button-down events, and the distance between the point of a button-down event and the point of a mouse-movement event.

Double Click Generation Method for Pen Operations

       Disclosed is a method of generating a double-click event
when a pen is used as an input device.  The method uses not only
button-down events but also mouse-movement events to generate a
double-click event.  The method uses the number of mouse-movement
events generated between two consecutive button-down events, and the
distance between the point of a button-down event and the point of a
mouse-movement event.

      A method of generating a double-click event of a mouse does not
work well when a pen is used instead of a mouse.  This is because a
user can move a pen faster than a mouse and place a pen to a
point faster and more easily than a mouse.  The method described here
can solve the problem.

      Assume that events occur as follows:
         button1 down event at (xd_1, yd_1, td_1)
         mouse movement event at (xm_1, ym_1, tm_1)
         .....
         mouse movement event at (xm_k, ym_k, tm_k)
         button1 down event at (xd_2, yd_2, td_2),
where first two numbers show the position of an event and the last
number shows the time of the event.  The method detects a
double-click event when

are satisfied.

      The described method generates a double-click event when two
consecutive button-down events occur in the predefined area and in
the predefined period, the number of mou...
