Definition of GUI:
- A Graphical User Interface (GUI) is how we interact with computers or devices using visual elements like icons, buttons, and windows.
Primary Interaction Mechanism:
- In a GUI, the main way we interact is by using a pointing device (like a mouse or touchpad), which acts like our electronic hand.
Objects in GUI:
- Everything you see on the screen, like buttons, icons, or windows, is an object. You can see, click, or interact with these objects.
Tasks and Interactions:
- Objects on the screen help us perform tasks. For example, clicking on an icon to open a program.
Independence of Objects:
- Each object is independent. You can interact with one without affecting others. Think of them like separate tools on a desk.
Actions by Users:
- People use the GUI to perform actions, such as clicking, selecting, or dragging objects around.
Operations on Objects:
- Operations include accessing (like opening a file) and modifying (like changing settings) objects through pointing and clicking.
Standard Behaviors:
- Every object follows certain rules. For instance, clicking a button usually performs a specific action. These are standard behaviors that users can expect.
