The reason for the design was because of the technology at the time. Rotary Dial (Pulse dialing) To dial a number, the user puts a finger in the corresponding finger hole and rotates the dial clockwise until it reaches the finger stop. The user then pulls out the finger, and a spring in the dial returns it to the resting position. For example, if ...

The most important factor is that at the time that telephones were invented, there was no such thing as automated call routing. There were people sitting in central switching stations. You told them, "Connect me to Mrs. Johnson", and they replugged the wires -- and here you go, you're now connected to Mrs Johnson. Later, automated call routing was invented, ...

The main reason was that it replaced hand crank telephones, and thus was a familiar interface. In the hand crank phone system, several houses were connected on one line, and each house was assigned a different ring pattern. For instance you might have been assigned one short ring, then a long ring. Your phone had a hand crank, a bell, a mouthpiece and a ...

Since you have phrased your question 'Is it acceptable...', the answer is: Yes it is acceptable. A lot of things are sub-optimal and still acceptable. Depends on your standards :) Is it the best possible choice of colors for this particular action? No, very likely not! It does one thing and only one thing very good - stand out, however it also introduces a ...

Well, when you close an application it is gone. The Windows OS has no control over how software developed by third-parties will handle this very final action. It is up to the developer to ensure that the state is saved. Will they prompt the user to save their work? Will the browser store the last page you were at if you close it accidentally? Who knows? In ...

Check out Google Drive - they use red buttons. I don't think that red signals error as long as the theme and GUI parts of the page goes in red (and that is probably why Google uses those colors). If there would have been a red and a green button, then I would have been suspicious about clicking the red, but in this case I don't get that feeling. The ...

After watching the video, I have some doubts about the veracity of their reactions, at least for some of them, but leaving that aside, I think the main problem now is that button interfaces are very common, almost anything is now a button, so the first reaction is to press something. Phones, remote controls, interfaces on computers and tablets, microwaves, ...

Color associations are very cultural thing. In computer culture I assume people usually don't think: oh blood, yammi. At least my experience is that red implies mostly one of the following: Attention: whatever it is, it must be important Error: As developers always wanted attention for errors, in the right context red is highly associated with errors. Just ...

The reason was that the telephone system required pulses to represent the numbers, and the technology did not exist at the time to generate pulses from pushbutton presses in a simple consumer device such as a telephone. The first automated telephone exchanges used electromechanical Strowger stepping switches that advanced one position for each pulse ...

Find something easy to learn This is an app so I assume your users are willing to take the burden of a little learning curve. With that in mind, adopt a convention and be totally consistent with it. They'll take to it quickly if it's clear enough. I think (as I'm sure you do) that a text label would clutter your interface. The most compact yet self-evident ...

This is very similar to the Should "Yes, delete it" be red, or green? question. Here is my answer to that. With respect to your particular question, Option B is what makes the most sense, as that is where your eye is naturally drawn to. That said, I would like to suggest an Option C: I would switch the order of the buttons so that the ...

I wouldn't rely on colours for the various reasons already given in the answers here. I feel that what you are really looking for is more suited to the play / pause paradigm, so perhaps the most intuitive way to handle this is to imitate the icons used to play / pause music and videos. On youtube and other video sites, a pause icon is displayed on the ...

I don't have evidence for this, but I think it is an example of end-end system design between the selectors in the exchange, the handset and the user. To route through one selector you need to connect and disconnect the battery a specific number of times, giving time between each 'pulse' for the selector to move into position. So you need something that ...

Rules of thumb that do not have a strong "WHY" attached are dangerous. Magic numbers too. With respect, using example by @Abektes "32 as magic number ... It was rule of internalization department." that rule could have been because the department paid for translation by the character? or longest word in any language? ... who knows why? One rule of ...

We are testing the exact same thing at the moment (hopefully I'll get back with the result when it'ts done). From our current experience and I've seen this on other sites, people tend do click the red button IF there is no other "actions". You have 3 buttons very close to each other and personally I would not click the red button. If it was Green I ...

I was going to post this a comment, but bits of it applied to each of the existing answers, so here it is in one place: There were a few push-button pulse-dial phones around (though wikipedia could do with a reference), and even more which had a switch to select pulse/tone (in fact every non-cordless landline phone I've owned. The real reason hinted at ...

A filter is a filter and a sort is a sort I find it rather hard to understand the purpose of the refresh button. But the answer to your main question is simple - filter means filter, sort means sort. When you filter something you take away other things. Here's a dictionary definition: Pass through a device to remove unwanted material. Consider what ...

I think there's a confusion between several elements: Action and current state: the button is supposed to allow me to RSVP as "Attending". But it also shows the current number of people attending. Is it a button or just a label? I and others: so the button shows that 18 are attending. How do I add myself as an attendee? I'm supposed to click a button ...

Aside from the case that has been made for improved readability, I also argue for sentence case it on the grounds that it's an easier rule to remember for people actually implementing (graphic designers, engineering, writers, etc.). Title case lends itself to all kinds of arbitrary decisions when implementers don't want to be bothered to look up whether ...

Title Case for Headings and Buttons It's easier and faster for users if they can to identify the shapes of words. "We recognize words from their word shape." also called the Bouma Shape.

On web you need user's focus as much as possible and this can be achieved via images/color and typography etc. Red is associated with eagerness, energy and attention. So when we see red(traffic light, blood, danger signs, waitress with red lipstick , red apple) we stop. And then take an action. So as per your screen you want user to validate before he hit ...

First of all, that 'article' that you were sent supporting the notion that red is good is ridiculous. It is not even an article, it is some lady opining about her child's behavior. It's stupid and doesn't mean anything. Moreover, the invocation of evolutionary biology is silly and incoherent. Who's blood are we seeing here? Maybe red is such a striking ...

Like mentioned, it's primarily to differentiate them without a visual. Another reason, and probably less so is that since the menu button is concave you're less likely to accidentally trigger it. So if you're playing a video and you accidentally trigger play/pause it's not so bad whereas triggering menu will take you out of the video completely. Car remotes ...

This is purely a matter of visual cognition - if the visual design makes it easy to group related elements, there is no problem putting anything anywhere, including buttons on a tab space. So long users can interpret the tabs as tabs and buttons (or other elements) as such, there shouldn't be a problem. In the top example, the distinction is fairly clear - ...

Your UX is all about "change the template". The required template may be (a) the default or (b) local file. In future say a selection from most recently used file list or a resource from a shared template library is useful. You could display this domain model this flat in the UI much as you have. But if extra capability or clarity is needed, then could ...

I've always wondered the same thing but I've never found an explanation from the source. The confounding part is that using a highly saturated "warning" color is in direct opposition to the fact that it is a destructive action. What they've achieved is undue emphasis. I tend to think there is more style than substance in this choice. Microsoft was once ...

You shouldn't use a close button. It will confuse users that understand that it's not a popup window they are seeing. I suspect that some users will fear that it closes the entire browser (or the current tab) and won't click it. Even if the user would like a way to get back to the previous page, it's better to use a dedicated back button on which a ...

The querant has asked the wrong question. When the automatic telephone switching system was developed, electronics was mostly electromechanical -- relays and switches and capacitors, gears and springs and solenoids. The dial mechanism wound a spring, and in returning to its resting position a set of gears and a cam repeatedly opened and closed a switch, ...

I strongly recommend against new window/tab links as core functionality of a web app. Web browsers and web apps communicate based on a set of principles called a REST architecture. REST is mainly an engineering principle, but it affects interaction design as well. Think, for instance, of the back button in your browser. Think of bookmarks. Think of people ...

I think either is appropriate, but you have to be clear with your language. For the starred favorite example, you have a few ways of phrasing it. Mark as Favorite / Remove Favorite (result of action) Not saved as favorite / Saved as Favorited (current state) In this case, the first option sounds way better to me. I find the tooltip (which I only now just ...
