Yeah, you're not wrong, has always been easy to use and well-known of the iPhone, in fact, we did not imagine the & ldquo; & rdquo ;. ease
All along, the debate on the iPhone easy to use or not, to a large extent reflect its notorious & ldquo; Back & rdquo; (back) button. When Android users can easily look flexor thumb, you can easily the & ldquo; Back & rdquo; on a stage; but iPhone users are the parents do not hate their own fingers be born a little bit longer, but also often end up left out out & hellip; & hellip;
Before WWDC Eve, introduced a new generation of iOS soon, Fan love child (micro-channel public number: ifanr) and you press the & ldquo together; return & rdquo; button to review the course of human-computer interaction iOS discuss the future of iOS way forward.
Antihuman & ldquo; Back & rdquo; button
As mentioned earlier, iPhone whether to use, most people never Tucao is & ldquo; Back & rdquo; button(The following figure): This button is located in the upper left corner of the screen, just touch the hardest we thumb position.
Apple knows this problem? You must know.
They, at the launch of iPhone 5, have on many occasions to promote its own is a single-handed control of the phone; in the iPhone 6 launch, more design & ldquo; Reachability & rdquo; feature that allows users to Home button by tapping , the screen is pulled down by the & ldquo; Back & rdquo ;. Moreover, Apple introduced iOS 7, they added a new & ldquo; edge of the screen & rdquo; gestures instead of & ldquo; Back & rdquo; button (below). Visible, Apple User Henji know this & ldquo; Back & rdquo; button.
The question is: has always been to design the interface and human-computer interaction and well-known Apple, since not unaware of the & ldquo; Back & rdquo; button very humanity, why they did not intend to improve this problem? We can not say that Apple intends to become arthritic users want it (laughs).
Abhimanyu Bhosale designer Q & A site Quora in the United States, theHad based HCI design principles so explained:
& Ldquo; HCI design & rdquo; in itself, is to allow humans can more easily use the computer, but why a & ldquo; & rdquo ;, design against humanity but for human-computer interaction?
About HCI usability (Usability), and Ben Shneiderman expert Jakob NielsenWe proposed the following five principles:
Bhosale mention the iOS & ldquo; Back & rdquo; situation, in fact, meet the point 4 & ldquo; easy to make mistakes & rdquo; principles, but completely contrary to point 2 & ldquo; efficiency & rdquo; principles ── thumb barely extends easy to point to the place, you can not say that it is efficient. Obviously, Apple adhere to & ldquo; Back & rdquo; button in the upper left, they inevitably feel some factor, compared to using a cell phone user's efficiency is more important.
According to Apple's & ldquo; iOS Human Interface Guidelines & rdquo; (iOS Human Interface Guidelines) pointed out, iOS the & ldquo; Back & rdquo; button has the following features:
In other words, the iPhone's & ldquo; Back & rdquo; button in the upper left, the purpose is to & ldquo; navigation & rdquo ;, allowing users to more clearly aware of their position, not the mystery of the road, in other words, & ldquo; Back & rdquo; button in the upper left is to & ldquo; learnability & rdquo; and & ldquo; & rdquo ;: memorability
& Ldquo; learn & rdquo; and & ldquo; easy & rdquo; the choices
Suppose there are & ldquo; efficiency & rdquo; interface that allows the phone easier to use words; it is more & ldquo; learnability & rdquo;, & ldquo; memorability & rdquo; the interface will allow users to more & ldquo; learn & rdquo; using a cell phone a. If Apple to & ldquo; learnability & rdquo;, & ldquo; memorability & rdquo; and insist on & ldquo; Back & rdquo; button in the top left; that is to say the apple of the & ldquo; learnability & rdquo;, & ldquo; can remember sex & rdquo; the priority placed in the user's & ldquo; efficiency & rdquo; before, is to say:
Apple think & ldquo; learn & rdquo; than & ldquo; easy & rdquo; more important.
Both took part in it? Have. Touch screen is intuitive, right? But for people who often typing, and then learn the tablet, and not an actual keyboard & ldquo; & rdquo ;. ease Likewise, it is very intuitive graphical interface, but for regular typing, or people who often use Photoshop, shortcut keys (Shot cut) must use the mouse to little more than point to be easy to use.
Although the & ldquo; learnability & rdquo; and & ldquo; efficiency & rdquo; two are not necessarily conflict, & ldquo; learn & rdquo; system necessarily is not & ldquo; easy & rdquo ;; but when the two are in conflict, Apple clearly tell you: the same is usability, Apple pay more attention to & ldquo; learn & rdquo; more than & ldquo; easy & rdquo ;, if the two there is a conflict in the interface, Apple will sacrifice & ldquo; efficiency & rdquo; to meet the & ldquo; learnability & rdquo ;.
Easy to learn, easy to use, both of which did not vary, but only the appropriate weight relationship. In fact, iPhone attention to & ldquo; learnability & rdquo; more than & ldquo; & rdquo ;, the early part of the efficiency can quickly get started, but in comparison, do not want to sacrifice efficiency to achieve & ldquo; learnability & rdquo; Android, and its users operational efficiency after skilled, may be higher than the iPhone (above).
In fact this has been Apple's tradition:Fan love child previously mentioned, Famous producer division Murch on Apple's Final Cut Pro X's & ldquo; upgrade & rdquo; very dissatisfied and decided to abandon, but he still affirm its interactive interface usability, and noted that it helps students and new users learning advanced clip capacity.
Final Cut Pro visible Hao, iOS Ye Hao, Apple's emphasis on & ldquo; learnability & rdquo; more than & ldquo; & rdquo ;. efficiency
However, even if Apple is & ldquo; learn & rdquo; is a priority, it does not mean they are completely abandon & ldquo; easy & rdquo ;: the iOS 7 beginning, iPhone joined the edge of the screen gestures (Screen Edge Gesture), thereby solving & ldquo; learn & rdquo; and & ldquo; easy & rdquo; contradiction, we previously mentioned designers Abhimanyu Bhosale, very sure of this interaction.
But iPhone current difficulties, we can see a group on this new screen edge gestures.
Dilemma interactive mode
Although iOS screen edge gestures 7 triggered & ldquo; Back & rdquo; features won praise, but the palm is relatively large, stick with a small screen phone love child norm senior editor Li Geng, with the iPhone 5c a year later, still use is not few users dislike the iPhone & ldquo; Back & rdquo; button ── because he has not been aware of the existence of this function.
Why he did not know the existence of this gesture? Because the edge of the screen gestures, not iOS basic gestures like intuitive.
In 2007 iPhone before the launch of the so-called & ldquo; & rdquo ;, just touch pen replace the mouse. At that time the touch screen by Windows affected mainly by the interaction click (Tape), drag (Drag) and press (Hold) composition, the use of mouse-style operation on the phone, whether or learnability efficiency, as not tall.
Later, iPhone became the first large-scale use touch gestures smartphones, really put & ldquo; touch & rdquo; into & ldquo; gesture & rdquo; intuitive, easy to use new era: the slide (Swipe), toggle ( Flick) and kneading pressure (Pinch) gestures, etc., then completely changed the touch screen interaction.
However unwittingly, iOS has developed about the tenth year, more and more functions, interactive approach is also the way to perfection; however, iPhone also need more and more new interactive way to trigger a new function and improve the undesirable interaction means. Below is the calendar year of the new iOS new touch interaction (not including the new iPad gestures), we can see the changes in the iPhone's interactive touch means:
With the iPhone more and more functions, more complex, traditional interactions and inadequate application, Apple more need to add new interactive way; but Apple has the easiest, most intuitive way to interact for the first the iPhone series, the next Apple simple interaction techniques can be employed less and less, so only by increasing complexity to distinguish between different functions:
More complex functions, more complex interactions, how to deal with Apple?
Easy to learn, easy to use dilemma
In & ldquo; operatively & rdquo; and & ldquo; Functional & rdquo; under increasingly difficult to balance the situation, Apple is still the first election & ldquo; & rdquo ;, to learn after the election & ldquo; & rdquo ;. ease
When Google have to play five every three Android operating mode to a major reshuffle of the occasion, Apple's mode of operation over the years has always insisted on the tradition. Even if they come as an earth-shaking style of great change in 2013 of iOS 7, but we can notice: Apple did not change the old way of interaction, but the more complex functions, superimposed on a more complex interaction on, as far as possible to prevent the new features that affect old operability.
So even if you do not know with any new features, you can still know how to use iPhone & hellip; & hellip; all the old features:
However, in order not to affect the function and operation of the old gesture, the new mode of operation most of the iPhone, or new features, as in the past are not very intuitive way to interact, leading to these new features have become not then & ldquo; & rdquo ;. ease In 3D Touch Case, press (Press) and long press (Hold) already very close to the action (below), and the reaction pressure sensors are also less than perfect, was not actually a very good means of interaction, but also 3D Touch function is not able to carry too much, the result can only become & ldquo; & rdquo ;. gimmick
Therefore, in human-computer interaction means increasingly complex, we can see:
A new generation of interactive mode
When we are still looking forward to what the next generation iOS new features, we may not have noticed: the & ldquo; learn & rdquo; as the core spirit of Apple, on the road more and more difficult of human-computer interaction.
Apple in the past few years has been to try new and more intuitive way to interact: Included in the 2011 natural language interaction (Siri), 2013 years of Biometric (Touch ID), 2014 years of Apple Watch, 2015 years of pressure sensing ( 3D Touch), Apple even made recently through the user's tendon and bone movement, gesture command to read input. But the problem is, Siri Ye Hao, 3D Touch Ye Hao, Apple Watch Ye Hao, Apple still failed to find a easier to learn than touch gestures, interactive and easier to use, and also because of this, iPhone development has been lagging .
Fan love child earlier reports that the Apple Siri will further optimize the 3D Touch and other interactive techniques in this year's WWDC, Apple's what we can expect in this new means WWDC able to produce it?
Apple Siri will put further development of interactive means of artificial intelligence? The 3D Touch or iPhone into a VR interactive doors?
