Chapter 2 Type of input data

• A lever that moves in all directions and controls
  the movement of a pointer or some other display
  symbol. A joystick is similar to a mouse, except
  that with a mouse the cursor stops moving as soon
  as you stop moving the mouse.

Chapter 2 Type of input data

• With a joystick, the pointer continues moving in
  the direction the joystick is pointing. To stop
  the pointer, you must return the joystick to its
  upright position. Most joysticks include two
  buttons called triggers.
• Joysticks are used mostly for computer games, but
  they are also used occasionally for CAD/CAM
  systems and other applications. (Analog
  Joystick )

Chapter 4 Comparative device

• Instead of using the joystick you can use the
  keyboard cursor (arrow) keys to modify the shape
  and position of the default function curves.
  Press the left/right keys to move the curves left
  or right. Press up/down keys to change the shape
  of the curves.
• You may also change the transparency of the slice
  as a function of the data values. Press and hold
  the SHIFT key while using the mouse or up/down
  keys to change the transparency

Chapter 5 Advantages

• It can used for entertainment like playing
  computer games and video games .
• Using joystick is more convenient and exciting
  than other input device like keyboard and mouse

12
Chapter 5 disadvantages

• It has limited usage. for example
  joystick only can press button in order to input
  the data thus we can not use joystick for drawing
  and writing
