iPhone is not "easy"

via:博客园     time:2016/6/11 18:00:38     readed:2112

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:

  1. When certain actions will change the motion picture content such as & ldquo; Close & rdquo; and & ldquo; Go home & rdquo; and so on, the display must be clear, but must not be easy to inadvertently. (Note: This refers iOS back button and the Location Ming, but not easy to inadvertently)
  2. In contrast, through the actual hardware button or implemented actions must be clear and frequently used functions, such as & ldquo; the volume keys & rdquo; and & ldquo; Home key & rdquo ;.
  3. The latest trend is to use gestures to express explicit action, such as & ldquo; slide & rdquo; (Swipe) or & ldquo; pull down & rdquo; (Pull down), but this action can not be too complicated, not too often. (Note: This refers to iOS 7 & ldquo; edge of the screen & rdquo; gesture triggers the & ldquo; Back & rdquo;)

& 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?

Contradictions HCI

About HCI usability (Usability), and Ben Shneiderman expert Jakob NielsenWe proposed the following five principles:

  1. Learnability (Learnability)
  2. Efficiency (Efficiency)
  3. Memorability (Memorability)
  4. Easy to make mistakes (Errors)
  5. Satisfaction (Satisfaction)

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:

iOSiOS

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

  1. Distribution via the interface from the top down, the user determines that each button is located on the system level (see above);
  2. Through system-level button, the user can predict the range of action buttons, and buttons are affected;
  3. Uniform buttons different levels of position, allowing users to more easily determine the different applications, the possible effects of various buttons.

& 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 ;.

easyeasy to learn

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:

iOSiOS HCI

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:

  • Home key is operated by a click (back home), double (multi-screen), three strikes (default Voice Over), press (Siri), fingerprint development to tap twice (Reachability);
  • Click the (Tape) from the usual one-click (click), the development of double-clicking (zoom in), press (Call Menu), and then to 3D Touch pressing action (Quick Menu);
  • Screen gesture by the slide (general drag), toggle (open page action), to more complex screen edge gestures (Notification Center, the control center and & ldquo; Back & rdquo; action), then adding the 3D Touch pressing gestures ( multi-screen);

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:

  • iPhone 4s Siri added a new feature to trigger its gesture is & ldquo; Long press the Home key & rdquo ;, but even if you do not understand the long-press the Home key to call Siri, you understand the basic operation of the iPhone.
  • iOS 5 added a new pull-down Notification Center, you must use the edge of the screen when a call gesture, from the edge of the screen to notify Pull center; however, my queen used iPhone for years, has been without notifying center, nor know how to use the notification center.
  • iPhone 6s added a new 3D Touch function, but you do not know with the 3D Touch, it does not mean you do not know with iPhone & hellip; & hellip; anyway 3D TouchMany people are still regarded as a gimmick.

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

3D-touch3D-touch

Therefore, in human-computer interaction means increasingly complex, we can see:

  • When the iPhone features more and more, we need more and more and more interactive way.
  • We need more and more interactive, interactive way to more complex.
  • Interaction becomes complicated, the development of new features will be more and more difficult when.
  • When Apple increasingly difficult to develop new features, iPhone improvements will become increasingly difficult.

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?
