Main Content
Welcome
Now that you're familiar with different types of technology, it's time to learn how to use your own device.
Whether you have a Windows computer, iPhone, Android phone or tablet, most devices work in a similar way. Once you understand the basic layout, using technology becomes much easier.
Don't worry if everything feels new. These skills quickly become second nature with a little practice.
What You'll Learn
In this module you'll learn:
- The Home Screen
- Apps and programs
- Icons
- Settings
- Notifications
- Brightness
- Text size
- Accessibility features
Lesson 1 — Understanding the Home Screen
The Home Screen is the main screen you see when you unlock your device.
Think of it like the front door to your home—it gives you access to everything else.
From here you can:
- Open apps
- Check the time
- View notifications
- Search for information
- See the battery level
- Connect to Wi-Fi
Spend a few minutes simply looking around your Home Screen without worrying about pressing anything.
Lesson 2 — What is an App?
An app (short for application) is a program that helps you perform a task.
Some common apps include:
- Phone
- Messages
- Camera
- Photos
- Calendar
- Maps
- Weather
- Internet Browser
Each app has its own icon.
Tap or click the icon once to open it.
Lesson 3 — Understanding Icons
Icons are small pictures that represent apps or actions.
For example:
📷 Camera
⚙️ Settings
📞 Phone
🌐 Internet Browser
Most icons are designed to be simple and easy to recognise.
If you're unsure what an icon does, simply tap it to explore—you won't break anything.
Lesson 4 — Opening and Closing Apps
Opening an app is easy.
On a phone or tablet:
- Tap the app once.
On a computer:
- Double-click the icon.
When you've finished:
- Return to the Home Screen.
- Close the program if needed.
Don't worry if you accidentally leave an app open. Modern devices manage this automatically.
Lesson 5 — Understanding the Settings App
The Settings app controls how your device behaves.
Inside Settings you can change things like:
- Wi-Fi
- Bluetooth
- Volume
- Brightness
- Text size
- Wallpaper
- Passwords
- Accessibility features
The Settings icon usually looks like a gear (⚙️).
You don't need to remember every option—just know that this is where most changes are made.
Lesson 6 — Adjusting Brightness
Brightness controls how light or dark your screen appears.
A brighter screen is easier to see outdoors but uses more battery power.
A dimmer screen saves battery and is often more comfortable indoors.
Most devices allow you to adjust brightness using a slider.
Lesson 7 — Changing Text Size
One of the best features of modern devices is that you can make text easier to read.
You can increase:
- Text size
- Icon size
- Display zoom
- Screen magnification
Making text larger can significantly improve comfort and reduce eye strain.
Lesson 8 — Accessibility Features
Accessibility features are designed to make technology easier for everyone.
Helpful features include:
- Larger text
- Voice Assistant
- Screen Magnifier
- High Contrast Mode
- Closed Captions
- Hearing Aid Support
- Voice Typing
Many people don't realise these features exist, but they can make using technology much more enjoyable.
Lesson 9 — Understanding Notifications
Notifications are messages that appear to let you know something has happened.
Examples include:
- New text messages
- Emails
- Calendar reminders
- Weather alerts
- Software updates
Not every notification needs immediate attention.
You can usually dismiss notifications and check them later.
Practice Activity
Spend 15 minutes exploring your device.
Try to:
✔ Find the Settings app.
✔ Adjust your screen brightness.
✔ Increase the text size if needed.
✔ Open three different apps.
✔ Return to the Home Screen.
✔ Find the battery indicator.
The more you explore, the more comfortable you'll become.
Tips for Success
✔ It's okay to press buttons and explore.
✔ Most mistakes can easily be undone.
✔ Practice using your device every day.
✔ Make text larger if reading is difficult.
✔ Ask for help when needed.
Summary
Understanding your device is one of the biggest steps towards becoming confident with technology.
Once you know where things are and how to navigate around your device, everyday tasks become much easier.
Remember, every expert was once a beginner.
