A keyboard is the most essential input device for the
computer. Although a keyboard contains navigation keys, in most cases we use a
pointing device like mouse to operate the cursor. There are many kinds of
pointing devices like mouse, track ball, touch pad, touch stick, joy stick and
so on each used for different purposes.
Although each of these pointing devices have specific
advantages, the disadvantages of using all these pointing devices is that they
occupy lot of desk space, clutter the table by using several cables and makes
the place messy. Many inventors have tried to integrate one or more of these
pointing devices with the computer so that the user can save space and get
operating comfort as well.
This article illustrates 14 inventions on integrating
various pointing devices to the keyboard. The patents are selected from US
patent database. The inventions try to combine a mouse, joystick, stylus, touch
