Home Screen of a Mobile Device
The home screen is the first (start) screen of a mobile device. There are three main parts of the home screen:
• Status Bar: It is the top part of the screen that displays icons like network signals, battery life, Wi-Fi, Bluetooth
connectivity, 4G/5G status, etc.
• App Icons and Shortcuts: The central part of the screen is the main part with different App icons and shortcuts.
These icons serve as shortcuts allowing users to launch their favourite apps with a simple tap. There can be several
pages depending on the number of apps used.
• Dock: It is the lower part of the screen that contains apps that are always visible, even if you change the page of the
screen.
Basic Gestures used with the Touch Screen of a Mobile
Gestures are movements made with the finger to interact with the touchscreen of your mobile device. For example, to
open an App, you tap on the touchscreen. Some of these commonly used gestures' that can be used on the touchscreen
are as follows:
• Tap: It is a quick touch or press on the screen that helps in selecting an item, opening an app, or activating a link.
• Tap and hold: This is similar to right-clicking your mouse, where you tap and hold your
finger on the screen.
• Drag: To tap, hold, and move your finger across the screen.
• Swipe: Slide your finger to the right, left, up, or down on the screen, mimicking the
action of turning a page.
• Double tap: To tap twice quickly. This will zoom out (increase the size of) of something.
For example, to make a word appear bigger.
• Pinch: Put your thumb, and finger together on the screen and bring it closer to zoom in
(reduce the size). For example, to make a picture appear smaller.
