SCREEN POINTING DEVICES

A device with which you can control the movement of the pointer to select items on a display screen, is a hardware input device that allows the user to move the mouse cursor in a computer program or GUI operating system.

Types of Screen Pointing Devices

1. Mouse
2. Track Ball
3. Touch Ball
4. Joystick
5. Light pen

Mouse

A mouse is a pointing device used to control the movement of a pointer cursor in a graphical environment. It is an alternative to the keyboard.

The different versions of mouse are as follows:

1. PS/2
2. Serial
3. Universal serial bus (USB)
4. Cordless

Parts of a mouse

A mouse is made up of the following parts:

1. Left button: This is used for clicking or double clicking an object.
2. Right button: It brings a task menu which contains some commands.
3. Mouse ball: This is a small round ball under the mouse which rolls or a mouse pad or smooth surface as the mouse is moved on the table.
4. Mouse pointer: This is a small arrow- shaped object that moves around on a computer screen and which is used to point at objects in a graphical operating environment.
5. Mouse cord: It is a tiny cord fixed onto the mouse for transferring signals to the processor

MOUSE TECHNIQUES

1. Pointing: Move the mouse to move the on-screen pointer.
2. Clicking: Press and release the left mouse button once.
3. Double-Clicking: Press and release the left mouse button twice.
4. Dragging: Hold down the left mouse button as you move the pointer.
5. Right-Clicking: Press and release the right mouse button.
6. Select and deselecting objects.

Presentation:

• Use visual aids to illustrate different pointing devices.
