SCREEN POINTING DEVICES
A pointing device can be defined as any hardware component that allows the user to input spatial data into the computer using physical gestures such as point click and drag.
TYPES OF POINTING DEVICES
There are several pointing devices that are
- Mouse:
- The mouse is an input device that is used for controlling the cursor on the computer monitor in order to point and select objects or give commands on the computer screen. It is usually placed on a mouse pad.
Two Types of Mouse The most popular types of mice are as follows:
(i) Mechanical Mouse:
It has a small ball at the bottom. The ball rotates as the mouse is rolled over a flat surface. Usually, a rectangular rubber pad (known as a mouse pad) is used as a flat surface. As the mouse is rolled over the flat surface, the pointer moves in the same direction on the screen.
(ii) Optical Mouse: It has no ball at the bottom. It uses laser technology to detect mouse movement. Nowadays, it is commonly used in personal computers (PCs).
FUNCTIONS OF THE MOUSE
- Clicking
- Pointing
- Double-clicking
- Right-clicking.
Touch Pad:
TouchPad is a pressure-sensitive pointing device. A touchpad is also known as a trackpad. It is also a stationary device like a trackball but it has no moving art. It is a small, flat surface (or sensitive pad) over which a user slides a fingertip to move the pointer on the screen.
TouchPad also has one or two buttons. These buttons are located near the pad. These buttons work like mouse buttons. TouchPad is commonly used with laptops. Nowadays, it is also available as a separate input device. It is fixed on a different keyboard.
Trackball:
A trackball is a pointing input device. It performs functions like a mouse but it is a stationary device. It has a moveable ball on its top. The ball is rotated or rolled with fingers (or the palm of the hand) to move the pointer on the screen. Like the mouse, a trackball also has buttons used to send commands to the computer.
Trackball is usually available on laptop computers. It is fixed on its keyboard. It is also available as a separate input device.
SUBJECT: ICT SCREEN POINTING DEVICE CLASS: JSS 1
STRATEGIES AND ACTIVITIES:
Activity I: The teacher leads by asking the learners about the previous topic
Activity II: The teacher introduces and explains the screen-pointing device to the learners.
Activity III: Learners will list the types of mice.
Activity IV: Learners will state the functions of the mouse.
Activity V: The teacher makes necessary corrections and also adds to the learners’ opinion
WRAP-UP & ASSESSMENT: in order to determine the level of understanding of the topic by the learners, the teacher will ask the following questions:
What are the functions of the mouse?
ASSIGNMENT:
Draw a well-labeled diagram of a mouse
