| Question 3 BDescribe several pointing devices, giving examples of each. A pointing device is an input device that allows a user to control a pointer on the screen. In a graphical user interface, a pointer is a small symbol on the screen whose location and shape change as a user moves a pointing device. Here are some examples of pointing devices: 1.Mouse A mouse is a pointing device that fits under the palm of your hand comfortably. The mouse is the most widely used pointing deice on desktop computers. 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. In addition to the ball, a trackball usually has one or more buttons that work just like mouse buttons. 3.Touchpad A touchpad is a small, flat, rectangular pointing device that is sensitive to pressure and motion. To move the pointer using a touchpad, slide your fingertip across the surface of the pad. Some touchpads have one or more buttons around edge of the pad that work like a mouse buttons. On most touchpads, you also can tap the pad's surface to imitate mouse operations such as clicking. Touchpads are found most often on notebook computers. 4.Pointing Stick A pointing stick is a pressure-sensitive pointing device shaped like a pencil eraser that is positioned between keys on a keyboard. To move the pointer using a pointing stick, you will need to push the pointing stick with a finger. The pointer on the screen moves in the direction you push the pointing stick. 5.Light Pen A light pen is a handheld input device that can detect the presence of light. To select objects on the screen, a user presses the light pen against the surface of the screen or points the light pen at the screen and then presses a button on the pen. 6.Touch Screen A touch screen is a touch-sensitive display device.Users can interact with these devices by touching areas of the screen. Because touch screen require a lot of arm movements, you do not enter large amounts of data using a touch screen. 7.Pen Input Mobile users often enter data and instructions with a pen-type device. With pen input, users write, draw, and tap on flat surface to enter input. The surface may be a monitor, a screen, a special type of paper or a graphics tablet. There are 2 pen input device which are Stylus and Digital Pen. A stylus is a small metal or plastic device that looks like a tiny ink pen but uses pressure instead of ink. A digital pen, which is slightly larger than a stylus, is available in two forms:some are pressure-sensitive: others have a tiny built-in digital camera. |
