Magnets for Taptic Engine on iPhone and Other Devices
Apple is using recycled rare earth elements in the Taptic Engine of the new iPhone 11 and iPhone 11 Pro, according to Apple’s Vice President of environment, policy, and social initiatives Lisa Jackson.
The Taptic Engine is Apple’s implementation of haptic user interface feedback. Using a linear actuator, devices like the iPhone 7 can reproduce the sensation of motion or generate new and distinct tactile experiences. In some cases, audio feedback from onboard speakers completes the illusion.
Apple applies its Taptic Engine to mimic a home button press, relay system notifications, and reinforce audio alerts. The technology doesn’t feel bolted on —feedback from the system feels natural, and in sync with what is being presented on screen.
A combination of “tap” and “haptic feedback,” taptic engine is a name Apple created for its technology that provides tactile sensations in the form of vibrations to users of Apple devices like the Apple Watch, iPhones, iPads, and MacBook laptops.
Apple debuted its taptic engine technology along with the Force Touch feature in the 2015 editions of Apple MacBook notebooks and the initial Apple Watch, and the two features work together to provide a user with more input control and feedback.
How Taptic Engine Technology Works on the iPhone and Other Devices
Taptic engine functionality became part of the iPhone in late 2015 when Apple added what it calls a “3D Touch” feature in the Apple iPhone 6S that senses the amount of fingerprint pressure applied to the iPhone 6S display and reacts accordingly.
With taptic engine functionality, users of Apple devices feel sensations that vary based on the type of feedback provided, which allows the device to quickly convey information without the user needing to look at a screen or display. For example, a taptic engine-enabled device may send one type of vibrating alert when new notifications arrive and another type when a meeting is about to start.
What is Taptic Engine?
The vibration function is the most-neglected function to the mobile phone users, but this function has a very important role in our daily life in actuality. Mobile phone will regularly vibrate with message or telegram under the silent mode which remind users do not miss. And nowadays, vibration has been more of an experiential function, such as vibration sense of virtual buttons during text input or vibrating effect of recoil force in shooting game. The vibration is generated by vibration motor in mobile phone and it can be classified into rotor motor and linear motor according to the vibration principle. Rotor motor has the advantages of simple manufacture process and low cost, but there are also some problems include slow start-up and large size which directly determine the decline of rotor motor against a background of thinner trend. Linear motor can convert electricity to mechanical energy directly and drive spring mass to do linear motion thus generate vibration. The linear motor can be further divided into transverse linear motor and longitudinal linear motor. Transverse linear motor can vibrate through both X-axis and Y-axis, then obtained relatively longer vibration stroke, higher start-up, controllable vibration direction and compact structure which will be more advantageous to the reduce the body thickness of mobile phone.
Currently, more and more mobile phone manufacturers equip transverse linear motor for their flagship products, but in fact, Apple is the originator in this area. Apple has firstly equipped transverse linear motor “Taptic Engine” in their smart watch, then abandoned previous eccentric rotor motor and start to utilize Taptic Engine from iPhone 6s.
What do they do?
Those of you who have been using laptops for a while may remember the tiny joysticks that were commonplace before touchpads emerged. They were serviceable after a bit of practice, but you wouldn’t want to go back to one.
Similarly, the first touchpads felt great, but you had to use separate mouse buttons as they couldn’t register clicks. They were a step forward at the time but I’m glad that I’m not still using one.
Apple’s Force Touch is just the latest attempt to make touchpads a little less awkward. Laptops can already register taps, and even detect multiple fingers at once, but now they’ve learned to measure how hard you press, which enables some new user interface tricks.
The name makes it sound more complicated than it really is. Apple does love to give names to features which probably don’t need names.
In truth, you don’t really “click” the Force Touch at all as the trackpad is solid and doesn’t actually depress. Instead you just get the sensation of a click provided by the “Taptic Engine”.
This name is a portmanteau of “tap” and “haptic feedback”, a technology which imparts forces or vibrations to the user to convey information. Think of a game controller which shudders when your character is shot: that’s haptic feedback.
The Watch has the same thing built-in. It even creates a tiny noise to go with the vibration, making the illusion of a mechanical click even more realistic. The same device also vibrates to alert you when notifications are received.
Underneath the Force Touch pad are sensors which detect how hard you press, which is key to the new MacBook interface.
Press on a file icon and it will be selected, just as on the current MacBooks, but keep pressing harder and it will open. Press the fast-forward button in a video player and you can vary the speed at which it skips by pressing lighter or harder.
All of the Multi-Touch features you already use – such as pinch-to-zoom and scrolling with two fingers – will remain. But these new features will give you an extra bit of control.
Both the Watch and the new MacBook have Force Touch and the Taptic Engine, and rumours suggest that the next iPhone will also have them. If so, we’d be likely to see a host of new apps – particularly games – spring up to take advantage of them.
