Answer:
Pinch and Zoom: One of the most common actions performed on touchscreens is pinch and zoom. With a traditional pointing device such as a mouse, you cannot perform this action. With a touchscreen, users can use two fingers to zoom in and out on text, images, and other content on the screen.
Swipe: Another action that is unique to touchscreens is swipe. With a traditional pointing device, you cannot swipe across the screen to navigate between pages or screens. With a touchscreen, users can swipe left or right to move between screens or pages, and up or down to scroll through content.
Multi-touch gestures: Touchscreens enable users to perform multi-touch gestures, which cannot be performed with a traditional pointing device. For example, users can use three fingers to swipe between open applications, or use two fingers to rotate an image or document. These multi-touch gestures are becoming increasingly common in modern touch screen devices.
