Gestures and Your Tab 4 NOOK’s Touchscreen

By Corey Sandler

You have several (officially labeled) ways to communicate with your Tab 4 NOOK’s touchscreen, with slight variations depending on the particular app or control panel in use:

  • Scroll: Touch a blank part of the screen — a place without an icon or command — and move your finger left or right. Some people slide gently and easily (their finger, that is), while others like to flick as if they were clearing a crumb from the table and onto the floor.

  • Touch: To open an application, select an item from a menu, approve a command shown as an onscreen button, or to enter a character from the onscreen keyboard, touch or tap an object or icon on the screen.

  • Touch and hold: Keep your finger on whatever you’ve touched to make a menu appear. Another use of a touch and hold is to select an item that can then be moved or dragged to another location. Another name for touch and hold is a long press.

  • Drag: You can move an item, icon, thumbnail (tiny picture) or other element that you select with a touch and hold. Don’t lift your finger from the screen before the item is comfortably in its new place.

  • Double-tap: Touch an item on the screen twice in quick succession. A double-tap zooms in on an image; do it again to zoom back out.

  • Swipe: Touch your finger on an item and drag it to another spot. Depending on the situation, you can swipe left or right, or up or down. Some apps might call this a slide.

  • Spread: This is a two-finger maneuver. Touch the screen with two fingers and move them away from each other to zoom in on or enlarge an image.

  • Pinch: Touch the screen with two fingers and move them toward each other to zoom out from or reduce an image (the opposite of a spread).

  • Rotate: Place two fingers on the screen — perhaps your thumb and forefinger — and twist them as if you were turning a dial. If the app supports this gesture, the image will rotate on the screen.

  • Sweep: Pass or sweep your whole hand across the whole screen, just lightly touching its surface. In some situations this captures a screenshot.

  • Cover: Cover the screen with the palm of your hand to pause the playback of a video or music file.

About the glass on the Samsung Galaxy Tab 4 NOOK: It’s pretty tough and not easy to scratch or break in ordinary usage, and if you drop your tablet onto a pile of bricks, it will probably scratch and break. Don’t try to control it with a sharp object like a pen or a chisel or a pocket knife. Do touch its screen as you would anyone or anything about which you care dearly.

A book is usually printed in portrait orientation (taller than wide) and a computer monitor is usually landscape (wider than tall). One of the beauties of a tablet is that you can often have it either way. Some applications — games and some video web pages like YouTube — are locked into one orientation or another, but others allow you to choose.

If you don’t want the image on the screen to reorient itself, you can turn off screen rotation. Pull down the notification panel from the top of the screen and tap the screen rotation icon. When it’s enabled, the icon is green; when it’s disabled, it turns gray with ennui. To turn it back on, just go back to the panel and tap it again.
