Abstract

Disclosed is a device for easy point-and-drag and point-and-click operations for computers, TVs, set-top-boxes, video games, or other similar applications. The device is created by adding a sensitive and small travel switch into mouse, trackball, or other remote control devices using switches and ball mechanisms, and positioning this switch properly just underneath the ball. This switch is not affected by the rolling movement of the ball, but can be activated ON/OFF by pressing down on the ball. This switch can be wired or programmed to be replacement, or redundant addition, of one of the existing switches of the mouse or the trackball.

Device for Easy Point-and-Drag and Point-and-Click Applications

      Disclosed is a device for easy point-and-drag and
point-and-click operations for computers, TVs, set-top-boxes, video
games, or other similar applications.  The device is created by
adding a sensitive and small travel switch into mouse, trackball, or
other remote control devices using switches and ball mechanisms, and
positioning this switch properly just underneath the ball.  This
switch is not affected by the rolling movement of the ball, but can
be activated ON/OFF by pressing down on the ball.  This switch can be
wired or programmed to be replacement, or redundant addition, of one
of the existing switches of the mouse or the trackball.

      Using trackball as an example, point-and-click is achieved by
rolling the ball to move the cursor to the desired or first position
on screen, and then pressing the ball once to activate this switch.
Point-and-drag can be achieved by a point-and-click operation first,
and then by further rolling the ball to the final or second position,
and then pressing the ball to activate this switch again to finish
the operation.  Thus the finger or hand that rolls the ball is the
finger or hand that operates this switch, resulting in easier use.

      For the case of a mouse, this switch is activated by the hand
pressing down on the mouse body.

      The precise positioning, and/or sensitivity, and/or travel
required to activate this switch can further b...
