1
Have you ever said a friendly hello to someone and then got caught in a long, drawn -out conversation?
2
You might have wanted out of it, but couldn't think of a polite exit.
3
Because there's no way to undo that hello, you might begin to avoid such niceties in the future.
4
User control and freedom is one of Jacob Nielsen's 10 usability heuristics.
5
It states that users often choose system functions by mistake and need a clearly marked emergency exit to leave that unwanted state.
6
Basically, support undo and redo.
7
A common example would be the back and forward buttons on every web browser.
8
Imagine if that didn't exist!
9
You'd have to be really confident in every single click as you navigate around the web
10
because there'd be no easy way to get back to where you were
11
if you clicked to visit a page and realized it wasn't what you needed.
12
Similarly, any process or mode in any digital system should include a way for users to back out when needed.
13
And websites can't only rely on those browser buttons, but should provide users a clear way to leave a stepped process
14
or cancel whatever it was they started on that webpage itself.
15
Undo or cancel is particularly important for mobile devices and other touchscreens, where accidental taps are common.
16
And again, these emergency exits should be clearly marked.
17
For instance, many people have no clue that some mobile apps allow undo by shaking the device,
18
just like you could shake to erase the classic Etch -a -Sketch toy.
19
If users never discover a feature, does it even exist?
20
When it's easy for people to back out of an unwanted process or undo an action, it fosters a sense of freedom
21
because they realize they don't need to be afraid to click on that link or test out that photo filter.
22
They know that if it turns out to not be what they wanted, they can easily undo that action.
23
They're always in control of the system and aren't going to get stuck somewhere they didn't intend.
24
Thank you.

- Grave a sua voz e compare com o original, prestando atenção a palavras como undo, exit, shake.
O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
