Almost everybody, even non iPad users know how to zoom in and out on iPad. Yes, I’m talking about pinch gesture which is made with two fingers. This gesture is very handy when you project your iPad screen onto the board to show something to your students. Most of the times students (especially the ones seated in back rows) can’t see clearly so they ask you to make the image larger. If the app lets you to use pinch gesture then there is no problem but if not then the following tip will help you. Before giving the tip let me create a scenario. Suppose you want your students to download an app. You show the icon of the app from your iPad’s screen and students can’t see it. Here comes a problem. In the main screen you cannot use pinch gesture so you need another gesture. You will use your three fingers.
Now, go to Settings>General>Accessibility>Zoom and turn the Zoom on. Now double-tap your three fingers. See? You can zoom in with three fingers where you can’t with two fingers While zoomed in you can drag the screen with three fingers. Below picture is what students see on the screen when I zoom in. The hard part of this gesture is adjusting the zoom level. You need to double tap on the screen and start doing the pinch gesture with two fingers. It might sound easy but believe me most of the people I know can’t do that. I don’t know why Apple created such a hard level adjustment.
