What's Force touch?

　What is Force Touch

Force touch also into pressure feeling control, force feeling control, there is no uniform name, is Apple for its products Apple Watch, new MacBook and a new 13-inch MacBook Pro, a touching sensing technology. Through the Force touch, the device can perceive the intensity difference between the light pressure and the pressure, and bring up different corresponding functions. Force touch differs from previous multi-touch multi-touch techniques.

Compared to the physical buttons, Force touch technology saves space and has large operating space, adding additional functionality to the application.

　　The technical principle of Force touch

Force Touch is currently used on the Apple Watch and the new 12-inch MacBook, so let's introduce the Force touch principle used on both products:

New 12-inch MacBook

New 12-inch MacBook Force Touch pad

Force touch in the four corners of the position to add 4 vibration feedback, you can perceive the strength of the press, the capacitive glass panel under the addition of "tactile engine (taptic Engine)", can be perceived more refined touching operation. This allows the touch to be no longer a single touch, multi-touch (Muti-touch) So simple, and can be based on the strength of the length of time to perform touch instructions.

　Apple Watch:

Apple Watch Farce Touch effect

Apple's Watch sensitive Retina display is surrounded by tiny electrodes that Force touch to perceive the difference between light and press and trigger a series of related reactions based on the actual situation. It can induce the user to click on the touch panel and give back different functions or controls. Touch control is not only the point control function, so that the short and long press will have different reactions. AppleWatch not only recognize each touch, but also perceive the strength, thus opening up a new space for your control.

　Force Touch How to use

The Force touch pad does not move, but you can still hear and feel clicks when you press it with your finger, thanks to the tactile feedback you have. When you click on the trackpad, the surface does not sink, but it produces a jolt, like the force feedback of the PlayStation or Xbox game handle. Apple has set up a sensor inside the Force Touch to detect finger compressions and to bring a sense of vertical movement to the operator's fingertips through the movement of gravity. Because can detect press strength, if you click the Force is bigger, touch board will recognize it as double click operation, this is also force touches function. In the actual experience, the function feels like two physical clicks.

(1) You can set the click Strength in the Trackpad Control Panel (small, Medium, strong), and the different clicks will trigger different actions, such as fast forward and zoom speed in the program. The entire surface of the Force touch pad provides tactile clicks, rather than the middle and bottom of the old trackpad, which have the proper click sense.

(2) Force Click (click in Force Touch) is similar to the traditional right click. For example, when you use Safari to browse the Web, the first time you click on the trackpad to select the text of the cursor hover position, and then once more power click on the trigger force click, the latter will be selected text to detect, and open dictionary entry or Wikipedia interpretation. In addition, the Force click can also identify the address and call out the Apple map, and if you try to search for a picture in the finder, it can also display thumbnails.

　　What Applications Force Touch supports

Talk about the application of Force Touch support before you talk about this technology for iOS system support and optimization

1, for the iphone has added a new functional dimension: for example, now double-click the Home button to see the current running program features, in the future can be replaced with heavy pressure operation. Similarly, now to quickly press the home key three times to open the voiceover and other ancillary functions, the future with the corresponding strength of the press can be achieved.

2, improve the Touch ID fingerprint registration method: It is well known, now the user must put the finger on the home key and then take away, and repeated this action to complete registration. In the future, with the help of Force Touch technology, users will be able to complete registration by weighing the home key and moving their fingers constantly. The iphone uses the home emulation layer to turn the sensor on and off, reading data from the user's fingerprint.

3, to play the game to expand the physical dimension: So in addition to the use of finger on the retina high-definition screen operation, users have to put a finger on the home key, so in the game run or encounter shooting will get vibration feedback.

4, improve the camera photography experience: Using different pressure, you can change the focus of the iphone isight camera.

　Force Touch support applications include not limited to:

Map: Force Click in the map can bring you two new features, direct Force Click allows you to mark a location, and touch-sensitive input allows you to reduce and enlarge the map, zoom speed is controlled by the strength of the finger press.

QuickTime: In QuickTime, you can fast-forward and rewind through force click, and touch-sensitive input allows you to control playback speed. The increase and decrease in press strength can speed up or decrease the video playback speed, and the touch panel also provides slight tactile feedback.

Mail: The force click in the message provides a wide variety of features, force click Click on a word to allow you to view the interpretation or related Wikipedia page, click on the address to open the map and show the appropriate location, and on the time and date of the click on the calendar to set you up.

Calendar: Like a message, force click a word in the calendar to let you view the interpretation or Wikipedia page, click on the address to open the map, and click on the contact to send a message.

Safari:force Click also offers many rich features in Safari browsers, including viewing word definitions, viewing the location of the address in the map, and customizing the itunes and App Store to bind to it.

　Force Touch the current application of Apple products have what

New MacBook

The new MacBook brings a refreshing touch experience. In the design of the Forcetouch trackpad, no matter where you click on the surface of the trackpad, you can get a responsive and consistent click Response. In addition, under the trackpad, there are power sensors that can detect your push and start a new way of interacting with your notebook computer. Now you can enable a series of new features by pressing long. For example, you can quickly see the word definition or preview file by simply clicking on the trackpad and holding it down. You can also experience tactile feedback, and the trackpad will emit tactile vibrations, allowing you to see the content on the screen through tactile sensing.

The Force Touch principle of the 12-inch new MacBook

The Force Touch pad used in the MacBook computer has a built-in taptic Engine, it gives you a click response to any pressing operation on the surface of the trackpad, such as a faint vibration when you stare at the screen and manipulate the trackpad, allowing you to operate more naturally and smoothly.

The Force Touch principle of the 12-inch new MacBook

Unlike the previous touchpad, the touch panel with Force Touch technology has two level contact feedback area, the first level touch feedback area is the normal point operation, same as the previous experience of the trackpad, while the second level touch feedback area is the main region of force touching pressure, The new features that are implemented by pressing pressure are mainly concentrated in this section.

Not only does Apple Watch:applewatch recognize every touch, but it also senses strength, which opens up new space for your manipulation.

Retina MacBook Pro 15: Just the new Retina MacBook Pro 15 also uses Force Touch technology, the same as the newer MacBook.

Next iphone: Rumor is that the next iphone will use Force Touch technology, and indeed Force Touch technology with fingerprint identification, home key combination has a lot of space.
