Advantage:

Trackball is stationary, so it does not require much space to use it.
Compact Size

Spaceball:

It is similar to trackball, but it can move in six directions where trackball can move in two directions only. The movement is recorded by the strain gauge. Strain gauge is applied with pressure. It can be pushed and pulled in various directions. The ball has a diameter around 7.5 cm. The ball is mounted in the base using rollers. One-third of the ball is an inside box, the rest is outside.

Applications:

It is used for three-dimensional positioning of the object.
It is used to select various functions in the field of virtual reality.
It is applicable in CAD applications.
Animation is also done using spaceball.
It is used in the area of simulation and modeling.

Joystick:

A Joystick is also a pointing device which is used to change cursor position on a monitor screen. Joystick is a stick having a spherical ball as its both lower and upper ends as shown in fig. The lower spherical ball moves in a socket. The joystick can be changed in all four directions. The function of a joystick is similar to that of the mouse.

Trackball

A trackball is a stationary pointing device with a ball on its top or side.To move the pointer using a trackball, you rotate the ball with your thumb, fingers, or the palm of your hand. In addition to the ball, a trackball usually has one or more buttons that work just like mouse buttons.

A mouse is a pointing device that fits comfortably under the palm of your hand.With a mouse, users control the movement of the pointer. As you move a mouse, the pointer on the screen also moves. Generally, you use the mouse to move the pointer on the screen to an object such as a button, a menu, an icon, a link, or text. Then, you press a mouse button to perform a certain action associated with that object.

Most desktop computer users today have some type of optical mouse, which uses devices that emit and sense light to detect the mouse’s movement. Some use optical sensors, and others use a laser. The latter, often referred to as a laser mouse, usually is more expensive than the former.

What is a stationary pointing device with a ball on its top or side?

2.Trackball A trackball is a stationary pointing device with a ball on its top or side. The ball in most trackball is about the size of a Ping-Pong ball. To move the pointer, you will need to rotate the ball with your thumb, fingers, or the palm of your hand.

Is a stationary pointing device with a ball?

Which pointing device has a ball on its top that can be rolled with fingers and the internal rollers sense the motion that is transmitted to the computer?

Trackball. The trackball is sort of like an upside-down mouse, with the ball located on top. You use your fingers to roll the trackball, and internal rollers (similar to what's inside a mouse) sense the motion which is transmitted to the computer.

What is the pointing device called?

The major pointing device is the mouse for the desktop computer and the touchpad for the laptop, although many road warriors bring along a mouse. Pointing sticks are available on some laptops, and a small number of users prefer trackballs over the mouse. See mouse, touchpad, trackball and pointing stick.
