检测输入路径是否存在错误_为什么存在用户输入错误
檢測(cè)輸入路徑是否存在錯(cuò)誤
Errors are a fact of life when using almost any type of software. Forms are the worst though. Nothing is more frustrating than filling out a form and getting a robotic message from the computer telling you that you have failed, please click ok to confirm your failure.
使用幾乎所有類型的軟件時(shí)，錯(cuò)誤都是生活的事實(shí)。 形式是最糟糕的。 填寫表格并從計(jì)算機(jī)中收到一條機(jī)器人消息，告訴您您已失敗，這讓您感到沮喪，請(qǐng)單擊“確定”確認(rèn)您的失敗。
為什么存在用戶輸入錯(cuò)誤 (Why user input errors exist)
Input errors don’t exist to make us feel stupid or ruin our day — even if it feels that way sometimes. They protect databases from incorrectly formatted or malicious data. They are like an immune system for the computer. They are there to protect it from anything that could be harmful.
輸入錯(cuò)誤不會(huì)使我們感到愚蠢或破壞我們的一天，即使有時(shí)會(huì)感到這種錯(cuò)誤。 它們可以保護(hù)數(shù)據(jù)庫免受格式錯(cuò)誤或惡意數(shù)據(jù)的侵害。 它們就像是計(jì)算機(jī)的免疫系統(tǒng)。 他們?cè)谀抢锸菫榱吮Ｗo(hù)它免受可能有害的影響。
Bad data can make your database sick錯(cuò)誤的數(shù)據(jù)會(huì)使您的數(shù)據(jù)庫不舒服But of course, the users on the other side don’t care about this. They just want to get their tasks done and achieve their goals quickly, easily and without any errors.
但是，當(dāng)然，另一側(cè)的用戶對(duì)此并不關(guān)心。 他們只是想快速，輕松且沒有任何錯(cuò)誤地完成任務(wù)并實(shí)現(xiàn)目標(biāo)。
錯(cuò)誤對(duì)用戶而言是痛苦的 (Errors are painful for users)
Errors aren’t life-threatening, but they are painful to recover from. Instead of watching your users suffer through errors, you can install some guard rails to prevent them from hurting themselves.
錯(cuò)誤并不會(huì)危及生命，但是要從中恢復(fù)是很痛苦的。 您可以安裝一些護(hù)欄以防止他們受傷，而不用看著用戶因錯(cuò)誤而受苦。
Avoid the ambulance at the bottom of the cliff.避開懸崖底部的救護(hù)車。預(yù)防勝于治療 (Prevention is better than the cure)
Rather than trying to find more polite or ‘user-friendly’ ways of telling your users that they are wrong, what if you spent your time preventing their mistakes in the first place?
與其嘗試找到更多禮貌或“用戶友好”的方式來告訴用戶他們是錯(cuò)誤的方式，不如您首先花費(fèi)時(shí)間防止他們的錯(cuò)誤該怎么辦？
Welcome to error prevention, the practice of designing things in a way that prevents your users from encountering errors.
歡迎使用錯(cuò)誤預(yù)防，這是一種以防止用戶遇到錯(cuò)誤的方式設(shè)計(jì)事物的實(shí)踐。
So how can you prevent input errors?
那么如何防止輸入錯(cuò)誤呢？
- Install invisible guardrails 安裝隱形護(hù)欄
- Collect only the data you need 僅收集您需要的數(shù)據(jù)
- Make the system do the heavy lifting for the user 使系統(tǒng)為用戶帶來沉重的負(fù)擔(dān)
Let’s dive a little deeper.
讓我們深入一點(diǎn)。
1.安裝隱形護(hù)欄 (1. Install invisible guardrails)
Guardrails are safety measures that restrict users from doing things that could result in error messages. If a form is well designed the user shouldn’t even be aware the restrictions exist.
護(hù)欄是限制用戶執(zhí)行可能導(dǎo)致錯(cuò)誤消息的操作的安全措施。 如果表單設(shè)計(jì)合理，則用戶甚至都不應(yīng)該意識(shí)到存在限制。
Most input patterns can be used as guardrails. The trick is to use them in a way that restricts the data the user can input to prevent mistakes.
大多數(shù)輸入模式都可以用作護(hù)欄。 技巧是使用它們來限制用戶可以輸入的數(shù)據(jù)以防止錯(cuò)誤。
滑桿 (Sliders)
A slider restricts the minimum and maximum values a user can input. This means the user cannot input a number that is higher or lower than allowed.
滑塊限制用戶可以輸入的最小值和最大值。 這意味著用戶不能輸入高于或低于允許的數(shù)字。
Sliders restrict the numbers you can input滑塊限制您可以輸入的數(shù)字踏步機(jī) (Steppers)
Steppers make it easier for the user to increase or decrease a value using the ‘+‘”’ and ‘-’ controls instead of their keyboard. You can user steppers to prevent the user from entering a number that is too high or low.
步進(jìn)器使用戶可以更輕松地使用“ +””和“-”控件而不是鍵盤來增加或減少值。 您可以使用用戶步進(jìn)器來防止用戶輸入太大或太小的數(shù)字。
Steppers make it easy to increment and decrement values but also restrict types of data that can be input步進(jìn)器使增加和減少值變得容易，但也限制了可以輸入的數(shù)據(jù)類型單選按鈕，復(fù)選框和開關(guān) (Radio buttons, checkboxes and switches)
Radio buttons, switches and checkboxes give the user preset options to choose from. This prevents the user from making choices that aren’t available.
單選按鈕，開關(guān)和復(fù)選框?yàn)橛脩籼峁┝祟A(yù)設(shè)選項(xiàng)供您選擇。 這樣可以防止用戶做出不可用的選擇。
Radio buttons restrict the choices you can make單選按鈕限制您可以進(jìn)行的選擇 Input select menus restrict your options輸入選擇菜單限制您的選擇 Switches only allow binary yes/no choices開關(guān)僅允許二進(jìn)制是/否選擇當(dāng)心文本輸入字段 (Beware of text input fields)
Text input fields can cause a lot of problems because they have no constraints. They allow the user to input whatever they want, often resulting in errors.
文本輸入字段沒有約束，因此可能導(dǎo)致很多問題。 它們?cè)试S用戶輸入所需的任何內(nèi)容，通常會(huì)導(dǎo)致錯(cuò)誤。
Input fields are the worst for user errors輸入字段最容易出現(xiàn)用戶錯(cuò)誤You can’t physically change your desktop or laptop computer’s keyboard to solve this problem, but with touch screens on mobile devices, you can!
您無法通過物理方式改變臺(tái)式機(jī)或筆記本電腦的鍵盤來解決此問題，但是通過移動(dòng)設(shè)備上的觸摸屏，您可以！
You can use different system keyboard types restrict the type of data the user can input, or even create your own custom keyboards.
您可以使用不同的系統(tǒng)鍵盤類型來限制用戶可以輸入的數(shù)據(jù)類型，甚至可以創(chuàng)建自己的自定義鍵盤。
System keyboards restrict the type of data a user can input系統(tǒng)鍵盤限制用戶可以輸入的數(shù)據(jù)類型2.僅收集您需要的數(shù)據(jù) (2. Collect only the data you need)
Most forms ask for more information than is necessary. Sometimes the data is being collected simply because the database ‘requires’ it.
大多數(shù)表格要求提供比必要更多的信息。 有時(shí)僅由于數(shù)據(jù)庫“需要”數(shù)據(jù)而收集數(shù)據(jù)。
But what is really required?
但是真正需要什么呢？
Unless you legally need to collect the data or it is business critical, investigate why you need it. Sometimes it can be because the person who created the database built it that way and nobody ever changed it.
除非您合法地需要收集數(shù)據(jù)或它對(duì)業(yè)務(wù)至關(guān)重要 ，否則請(qǐng)調(diào)查為什么需要它。 有時(shí)可能是因?yàn)閯?chuàng)建數(shù)據(jù)庫的人以這種方式構(gòu)建數(shù)據(jù)庫，卻從未有人更改過它。
Do you really need to know your user’s middle name and last name? Do they even have one? In Indonesia, for example, it’s not common to have a last name. I personally don’t have a middle name, my parents never gave me one.
您是否真的需要知道用戶的中間名和姓氏？ 他們甚至有一個(gè)嗎？ 例如，在印度尼西亞，姓氏并不常見。 我個(gè)人沒有中間名，我的父母從來沒有給我一個(gè)。
Databases make broad assumptions about the world that are often wrong. Challenge those assumptions and simplify your forms by removing as much as you can.
數(shù)據(jù)庫對(duì)世界做出廣泛的假設(shè)，而這些假設(shè)通常是錯(cuò)誤的。 挑戰(zhàn)這些假設(shè)，并通過盡可能多地刪除來簡化表格。
Don’t collect data if you don’t need it. The more data you collect the more chance for errors.
如果不需要，請(qǐng)不要收集數(shù)據(jù)。 您收集的數(shù)據(jù)越多，出錯(cuò)的機(jī)會(huì)就越大。
3.讓系統(tǒng)為用戶做繁重的工作 (3. Make the system do the heavy lifting for the user)
The system should do the hard work, not the user系統(tǒng)應(yīng)該努力，而不是用戶Doing the heavy lifting for your users means the system should anticipate and handle potential problems.
為您的用戶完成繁重的工作意味著系統(tǒng)應(yīng)該預(yù)見并處理潛在的問題。
This means knowing what the most common user journeys are and offering helpful suggestions or shortcuts.
這意味著了解最常見的用戶旅程并提供有用的建議或捷徑。
You can do this by using smart defaults, generated names and error correction.
您可以使用智能默認(rèn)值，生成的名稱和錯(cuò)誤更正來做到這一點(diǎn)。
智能默認(rèn) (Smart defaults)
Smart defaults pre-fill or preselect an option for your user. They are either personalised to the user or the most common use case.
Smart默認(rèn)為用戶預(yù)填充或預(yù)選擇一個(gè)選項(xiàng)。 它們要么是針對(duì)用戶的個(gè)性化設(shè)置，要么是最常見的用例。
The reason they are so effective at reducing errors is that they prevent forms being submitted with things not filled in. The user doesn’t need to do anything other than review the suggestions and make changes as needed.
它們之所以能夠有效地減少錯(cuò)誤，是因?yàn)樗鼈兛梢苑乐固峤晃刺顚憙?nèi)容的表單。用戶除了查看建議并根據(jù)需要進(jìn)行更改外，無需執(zhí)行其他任何操作。
You could use machine learning here, but optimising your form for the most common use case goes a long way.
您可以在這里使用機(jī)器學(xué)習(xí)，但是針對(duì)最常見的用例優(yōu)化表單要走很長一段路。
For example, when searching for a flight most people choose a return trip you can use geolocation to determine where they are most likely departing from.
例如，大多數(shù)人在搜索航班時(shí)選擇回程，則可以使用地理位置來確定他們最有可能離開的地方。
Smart defaults make choices for the user that they can change智能默認(rèn)值會(huì)為用戶做出可以更改的選擇When searching for accommodation, the majority of people travel with another person.
在尋找住宿時(shí)，大多數(shù)人都會(huì)和另一個(gè)人一起旅行。
Why not make some educated guessed about your users?為什么不對(duì)您的用戶進(jìn)行一些有根據(jù)的猜測(cè)？These ‘smart’ defaults aren’t very smart and won’t always be right, but making a few educated guesses is much more preferable to forcing everyone to fill in the entire form from scratch.
這些“智能”默認(rèn)值不是很聰明，也不會(huì)總是正確的，但是進(jìn)行一些有根據(jù)的猜測(cè)比強(qiáng)迫所有人從頭開始填寫整個(gè)表格更為可取。
產(chǎn)生的名字 (Generated names)
When creating a file giving it a name is the only way to recognise and retrieve it later. You are probably familiar with this when you use Google Docs or Microsoft Word.
創(chuàng)建文件時(shí)，給它一個(gè)名稱是稍后識(shí)別和檢索它的唯一方法。 使用Google Docs或Microsoft Word時(shí)，您可能對(duì)此很熟悉。
What you may not have noticed is that many applications suggest or pre-fill a name for you. Google docs do an excellent job of this by generating the document the title or from the first line.
您可能沒有注意到的是，許多應(yīng)用程序會(huì)為您建議或預(yù)填一個(gè)名稱。 Google文檔通過生成文檔標(biāo)題或第一行來做得很好。
You can actually apply this concept to any situation where a user needs to fill in a name. Suggest one for them based on the data you have available.
您實(shí)際上可以將此概念應(yīng)用于用戶需要填寫姓名的任何情況。 根據(jù)可用數(shù)據(jù)為他們建議一個(gè)。
結(jié)語 (Wrapping it up)
You can’t completely banish errors from your form designs, but thoughtful design decisions that prevent them is much better than trying to make them more user friendly. Prevention is better than the cure.
您不能完全消除表單設(shè)計(jì)中的錯(cuò)誤，但是周到的設(shè)計(jì)決策可以防止錯(cuò)誤發(fā)生，這比嘗試使它們更易于使用要好得多。 預(yù)防勝于治療。
Just remember:
只記得：
- Collect only the data you need 僅收集您需要的數(shù)據(jù)
- Install guardrails 安裝護(hù)欄
- Make the system do the heavy lifting for the user 使系統(tǒng)為用戶做些繁重的工作
