With TalkBack gestures, you can easily control your Android device.

They are divided into three types: basic, transition gestures and angular. They must be performed in one movement, at a constant speed, evenly pressing on the screen.

Basic gestures

Transition gestures

Angle gestures

These gestures consist of two lines forming a right angle. For example, to go to main screen, you must first swipe up, then sharply to the left at an angle of 90 degrees (this gesture is set by default).

Note. The gesture to open the notification panel (right then down) is not supported in all versions of TalkBack. If it doesn't work on your device, swipe down with two fingers from the top of the screen.

Gestures with two fingers

All TalkBack gestures are performed with one finger. As long as you touch the screen with one finger, your gestures are only sent to TalkBack.

However, when using two or more fingers, your touch or gesture is recognized directly by the app and not by TalkBack. For example, you can scroll through pages with two fingers.

Some applications allow you to zoom in and out by placing two fingers on the screen and pinching or spreading them. TalkBack does not prevent these gestures from being recognized.

Set up TalkBack gestures

All of the above gestures are installed by default. You can change their purpose if you wish.

Android devices use a touch screen. For users who are accustomed to push-button controls, it can be difficult to switch to touch screen operation.

Button control uses a keyboard and mouse, while touch screen control is performed using fingers or a stylus.

On the one hand, gesture control seems a little primitive. On the other hand, Android gestures open up new horizons for various programs that would be very difficult or impossible to implement in a button version.

Touch screen control is that it responds to touch with fingers or a stylus, and, if necessary, repeats exactly these movements. If the device recognizes touches or movements as commands, then they are executed exactly as commands. The task of the user is simple - to master pressing the touch screen so that they lead to the execution of those commands that will be understandable to the device and that the user needs.

Let's take a look at the top seven techniques used on touch screens. Android gestures can be the following:

1. Touch (press)

Tapping (or tapping) is the primary action most commonly used on a touch screen.

Touch is necessary in many cases:

• to enable features,
• to launch any application,
• activation of one or another parameter, element,
• to select the desired icon or the corresponding option in the list,
• to enter text
• etc.

Touching is simple. It is easy enough to touch with your finger or stylus in the required place on the screen, for example, touch the icon of the desired application.

To enter text, just touch the desired field, a virtual keyboard will automatically appear, you can type text by touching the keys with the desired characters.

I involuntarily recall how many years ago I went to the terminal, pressed the buttons of the terminal in order to put money on mobile phone. In general, I did everything as usual, but nothing happened on the terminal, the terminal did not respond to the buttons. So I did 3 or 4 approaches to the terminal on different days with zero result. On some good day, a young man who was standing in line at the terminal behind me said: “What if you press your finger on the screen?”. And here it is, happiness: I pressed my finger on the screen and the terminal began to respond to pressing, everything worked out. So I first met with a touch screen.

2. Double tap

Double tap (or double tap) is used to fast scaling, to launch some applications and other actions.

To change the scale, for example, when viewing a web page, you need to quickly touch the screen 2 times with a minimum interval. To return to the previous state, you must again double-tap the screen.

One double-tap turns on the corresponding option, a second double-tap cancels the same option.

If you compare Android with Windows, then double-tap in Android is somewhat similar to double-clicking the left button in Windows.

3. Touch and hold

Pressing (touching) with holding is used to open additional options, if any.

You need to touch the desired area on the screen and hold your finger for a few seconds. At the moment of touching and holding, nothing happens, and this may be somewhat surprising at first. But as soon as you release your finger, an additional menu will immediately appear or another action will occur as a result of a touch and hold.

This action is very similar to right-clicking in Windows, when after right-clicking on an object, a so-called context menu appears with additional options object.

4. Swipe (swipe)

Swiping can also be called swiping or scrolling. Lightly touching the screen, without releasing your finger, slide your finger from top to bottom, from bottom to top, from left to right, or from right to left, that is, as if to brush off the “dust from the screen” slightly in the right direction.

Swiping (swiping) is used to switch between pages on the Desktop, to scroll through various lists, etc. Depending on the Android lock screen setting, it may be that swiping diagonally (diagonally) means unlocking the screen - this swiping also applies, and not just swiping from bottom to top or right to left.

When I first needed to send a message in Russian on my smartphone, for this I had to change the layout from English to Russian on the virtual keyboard. I tried all the options, even went into the language settings - it didn’t work out in any way: the English layout “stood in its tracks”. I was told that I just need to lightly wave my finger over the space from left to right. By the way, I saw the inscription "English" on the space bar on the virtual keyboard, I pressed it, but to no avail. And as soon as she waved her finger over the space, the layout immediately changed to Russian. Here it is swiping, it works!

5. Drag and drop (drag and drop)

Dragging (or dragging) is required to move apps around on the screen, as well as to move folders, icons, and the like.

It is necessary to touch the required element, wait for it to be selected, then, without releasing your finger, move this element (folder, file, icon, etc.) to the desired point on the touch screen.

6. Bringing and spreading fingers

Simple and useful feature to change the scale of what is displayed on the screen: picture, text, map, diagram, etc. You can zoom in and out again if needed.

To do this, you need to touch the screen with two fingers (or several) at once and, without taking your fingers off the screen, spread them apart. The scale will increase proportionally.

If you touch the screen with two fingers (or several) and, without lifting them off the screen, bring them together, then the scale will decrease.

7. Change screen orientation

Portrait (vertical) orientation is convenient for reading books. Landscape (horizontal) orientation is good for watching videos and various maps. All this, of course, is not for everyone, everyone chooses for himself which orientation is better in this or that case.

To change the orientation from one to another, you just need to turn your smartphone. In this case, the Screen rotation function must be activated in the screen parameters. If the function is disabled, then the image will not be rotated.

That's not all possible options gestures, but perhaps the most basic and frequently used. Other gestures, such as turning in a circle, etc. are used less often, and these gestures may not work in every program. As a rule, the listed gestures are enough for all occasions, or almost everything.

They are mastered easily and quickly, but first you need to practice a little. Gestures are logically clear, you expect exactly this action from them. Is that touch with hold - it's a little unnatural. The rest of the gestures are intuitive. That's why it's easy to remember.

We bring to your attention a short glossary of jargon related to touch screens.

Gestury , gestures (gestures) - certain movements on the screen of the pointer, in this case - a finger or , allowing you to replace certain commands or their sequences. Significantly speed up and simplify the work with mobile devices.

touchscreen (touch screen, touch- touch) - a touch screen that responds to touch. In addition to mobile devices, it is used in terminals and ATMs.

Tap and double tap – (tap- press) - a short press on an element of the touch screen interface, akin to clicking a mouse. Respectively, double tap - double click.

You may be able to pass for the so-called true Gramar Nazi, but most likely you will simply look like a noob in the eyes of the interlocutor, i.e., a stupid beginner.

These days are nothing new, you can see them everywhere. For many years we have been using them in ATMs and payment terminals. In some grocery stores, you can order various dishes by pressing the touch menu buttons. So by and large, the iPad's touchscreen shouldn't be new to you.

But for iPad usage it takes more than just a touch. You tap, double tap, press and hold buttons, swipe and drag icons, swipe across the screen. What movements you will make and when - depends on what you want to do. We have already covered the main ones, this article will help you figure it out on the iPad.

Sometimes, there may be problems with the touch screens of mobile devices. They may be caused by a hardware failure, in which case contact your service center where you can always repair your favorite gadget.

You'll learn how to perform a "finger dance" to get iPad to respond to all your commands. You'll also learn a few keyboard shortcuts and how to use your fingers to find things on iPad. So stretch your arms and get started.

The "brain" of the iPad is his operating system— smart enough to respond to a series of very different touches.

Finger movements depend on what you want to do. The following actions are possible.

• Pressing. Lightly press with your fingertip on the icon, shortcut, song name, or control you see on the screen. The iPad isn't a crude old calculator, so you don't have to press hard, just a light touch is enough.
• Drag and drop. Press your finger on the glass and slide it to the side to move to different parts of the screen. This way you can control the volume controls and navigate through the photos. Dragging with two fingers moves the window within the window (for example, the floating window that appears in the Facebook window when you bring up your friends list).
• Move. Moving is similar to dragging, except that it is used for only one control - the Unlock / Confirm buttons (Unlock / Confirm). It's on the "track" where you move the slider when waking iPad from Sleep or confirming it's completely off.
• Scrolling. Easily and quickly swipe up or down the screen and browse a web page or song list in the swipe direction. The faster you scroll, the faster the screen scrolls. In the photo album, swipe from side to side so that the images follow each other on the screen.
• Reduction and separation of fingers. To zoom in on part of an image, document, or web page, put your thumb and forefinger together, place them on the screen, and then spread them apart. To zoom out, place your fingers apart on the screen and pinch them together.
• Double click. Two alternate presses are needed in several situations. First, this fast way enlarge a photo or web page. Secondly, if you are watching a video, then this allows you to switch the ratio of width and height. AT full screen mode(shown on the left) the edges of the frame are cut off. The widescreen view (shown on the right) is preferred by moviegoers because it makes the movie look the way the director intended.

Dear friends who are starting to master the smartphone!

If you have switched from a conventional push-button mobile phone to a touch screen smartphone (touch screen - touchscreen), then some of you initially experience difficulties with the development of the touch screen. It is not very clear to you how to touch the screen, how long to hold the touch, how to navigate the page, etc. In this article I will try to briefly describe the main features smartphone control.

I must say right away that the transition from mechanical buttons to virtual ones is a huge step forward in the development of mobile devices. It allows you to increase the screen area to almost the entire front surface of the smartphone and make it easier to manage. But at the same time, at first, there is also some inconvenience. Ordinary phone you could take it in your hand as you like and touch any part of the front panel and screen. With smartphones, you need to be more careful, because any accidental touch of the screen surface can cause unwanted action. You need to develop the habit of holding a smartphone in your hand without touching the screen unnecessarily, at least while it is in an unlocked state.

So, here basic management techniques touch screen:

Single touch (tap)

it rapid(almost no delay) touching the screen with one finger. The delay should not exceed 0.5 seconds. Any touch is easy enough to do, as today's capacitive touch screens are very sensitive (unlike the resistive ones that have gone by the wayside).

On the home screen (and any desktop screen), a single tap on an application icon launches the application. it analogue of pressing the left button mice on a regular computer. In other cases, inside the application, this can be choosing from several options, choosing a contact in the contact list, confirming an action, etc.

Single touch in text fields inserts the cursor at the touch point.

Long tap

This touch with one finger With delay more than 1 second (until the result appears). The result may vary depending on the situation. In most cases, this action results in context menu (analogue right button mice).

Delayed tapping of an icon on the main screen leads to “sticking” to the finger of this icon, which makes it possible to move it around the screen, including to the adjacent home screen, as well as deleting the icon (not the application itself) to the basket that appears on the screen.

In text fields, delay results in fragment selection text under the finger with the possibility of further expanding the selection with the resulting end marks, at the same time a menu appears Copy, Select All, Cut, Paste. Pausing on the cursor label causes the menu to appear Insert(last clipboard content), Paste from clipboard(any of the last 20 clipboard contents).

Double tap (double tap)

Double tap with one finger with a short interval between taps (no more than 0.2 sec). Used to alternately zoom in and out of a web page in a browser, an image in the Gallery, etc. You need to click exactly on the area of ​​the screen that you want to view larger and in more detail.

Touch with movement (tap & drag)

This touch with one finger with immediate (delay no more than 0.2 sec) start of movement finger across the screen without releasing your finger. A further delay in one place after the start of the movement does not play a role: the contents of the screen seem to stick to the finger until it is released. This is how you scroll through desktops (screens), pages in the browser in any direction, scroll through lists (for example, contacts), etc. This gesture also serves to move the sliders of various virtual controls (eg volume, brightness, etc.).

Swipe

This action with one finger is similar to the previous one, but it is done without a long movement around the screen, reminiscent of a quick brush stroke on paper. At the same time, the contents of the screen continue to move even after taking your finger off the screen in the process of “stroke” with a gradual slowdown. I remember a video of the first demonstration of this effect by Steve Jobs on Apple presentations iPhone 2G in 2007 broke a flurry of applause.

Now let's look at touch techniques. two fingers. In this case, the fingers can be on one hand or on different ones, it does not matter.

Convergence (pinch) and breeding of two fingers (pinch, zoom)

This technique is used to smoothly decrease and, accordingly, increase the scale of the image on the screen (pictures, web pages). You put both fingers on the screen at almost the same time, and then make a movement to bring your fingers together (pinch) or spread them apart. The direction of movement of the fingers (right-left, up-down or intermediate movements) does not play a role.

Rotation with two fingers (rotate)

This is another technique used to rotate the image on the screen. After touching the screen, two fingers move each along a circular arc in the same direction (clockwise or counterclockwise). Or one finger stands motionless at the center of rotation, while the other moves in an arc around this center. This method is rarely used. For example, I used it when editing an image in the MDScan application to get scanned copies of documents.
