                   The student will be able to:
                      understand the importance of UI components in app design.
                      identify and use various UI components.
                      apply touch events to enhance app interactivity.
                      create visuals and animations using the Canvas component.
                      design and test interactive apps with Canvas and touch events.



                 MIT App Inventor provides a simple yet powerful platform for designing mobile applications
                 with an intuitive User Interface (UI) and interactive features. UI design in App Inventor
                 involves arranging visual components like buttons, labels, images, and canvases to create
                 user-friendly apps.




                           USER INTERFACE OF MIT APP INVENTOR


                 User Interface  (UI)  components  in  MIT App Inventor are the  building  blocks  used  to
                 design the visual and interactive elements of a mobile application. These components are
                 drag-and-drop elements that allow users to create the layout and functionality of their
                 app without needing to write code. Examples of UI components include buttons, labels,
                 text boxes, images, sliders, and more.


                 WHAT ARE UI COMPONENTS?
                 UI components are tools that help you design and organise how users interact with your

                 app. These components are added to the Viewer pane in the Designer window of MIT App
                 Inventor. They are found in the Palette and can be dragged and dropped onto the screen.

                 Why are UI Components Important?

                 UI components are important because:
                   They enable users to interact with your app.

                   They make the app visually engaging.
