Apple has attached a hidden button to your iPhone, and you may not have seen it before
No, Apple didn't come into your house and stick a button on
your mobile secretly. But it did release the latest version of its iPhone
software, iOS 14, which includes a Back Tap feature. Back Tap adds to your
phone a fascinating new "button" which blurs the line between hardware
and software.
Back Tap turns your iPhone's entire back into a giant
touch-sensitive button that you can double or triple tap to activate unique
phone features. There's a fair chance you really haven't seen it. Apple slipped
the Back Tap settings into its Accessibility menu.
Its intended aim is to provide more ways for users to
communicate with their devices. Most of the Back Tap options illustrate this by
opening the app switcher, notification menu, or control center settings;
scrolling through an app or website; activating Siri; or taking a screenshot.
But Back Tap also links into the extremely robust Shortcuts
app from Apple, which means that you can make these new buttons do almost
everything you can imagine effectively.
It's a fascinating type of button: totally invisible to the naked eye, completely non-functional until it's activated by software, but can be tasked with just a fast tap to open, communicate with, or accomplish almost any task on your smartphone.
Software customization
This customization of the software is important. A future in
which Apple limited Back Tap to only a few preset choices aimed at making the
iPhone UI more available is easy to imagine.
But the company turned Back Tap into a tool of unlimited
ingenuity by opening it up to shortcuts, enabling consumers to come up with
their own ways to take advantage of the new button on the back of their
smartphones.
It's not just Apple. Google experimented with a similar,
but more constrained, Android 11 feature, although it didn't end up making the
final cut. Since then, some enterprising developers have replicated the feature
for any Android device.
This is also a control level that for iOS devices is almost
unheard of. Imagine if Apple allows you to reset the side button on an iPhone
12 to, say, launch Google Assistant, or give your
partner a preset text message. It is literally inconceivable.
It's also going well. The program is sensitive, and whatever
Apple does to distinguish between a deliberate tap and just keeping your phone
constantly, it works perfectly.
I found it especially helpful to activate the Control Center
to change device settings quickly.
A button that is almost absolutely free from the limitations
of APPLE
To build a new hardware interaction that wasn't possible
before, Back Tap repurposes the current sensors and hardware on your iPhone
with software. It's a new physical button with which users can communicate, but
one that's almost entirely free from the limitations of Apple.
The most direct form of interaction is physical buttons, of
course. This is why Samsung insists on a tailor-made Bixby button and why
Netflix pays for a spot on the remote of your Roku. And while Apple may not be
able to give up control of the physical buttons on your iPhone, the next best
thing is Back Tap
