Screen digits are right aligned to maintain positional consistency between what a number represents (in base 10 that would be units, tens, hundreds, etc.). E.g. If I were to have 764 and then multiply it by 24, the answer would be 18336. By aligning to the right I've consistently seen the same unit representation in the same position, and when I've had new ...

We ran a quick user test and found that more people were signing up with their emails If you trust your test, then you should trust your users and design a solution that meets their desires. We are trying to encourage users to connect with their Facebook/Twitter accounts instead Why is that? Do you have sound reasoning behind this in that it will ...

If the user can type it then it should be allowed in their password. Telling someone what they can and can't use in their password always feels wrong to the user. Passwords are currently the most universal way to authenticate. Preventing users from entering anything is, in essence, telling them who they can or can't be. 1. Any printable character that a ...

The site Good-UI argues for Undo: Try Undos instead of prompting for confirmation. Imagine that you just pressed an action button or link. Undos respect the initial human intent by allowing the action to happen smoothly first and foremost. Prompts on the other hand suggest to the user that he or she does not know what they are doing by questioning their ...

You are totally right As with many other devices (eg the QWERTY keyboard) the hot/cold tap persists not because it's the most usable design, but because of: Cost since proper temperature control requires an electromechanical feedback loop design, or calibrated thermostatic valves which needs to be periodically adjusted or replaced. This drives up the cost ...

hiding the scroll bar is a bad practice, for a few reasons: some people do not have a scroll wheel - just as you're worried. Just like how that impoverished county an hour away counts as "3rd world economy" by international standards, so too today do we find unusual relics of usability times 'long past' the scroll cursor is an indicator of position. It ...

Historically It is a simple fact that traffic signals were introduced in 1868. From The Origin of the Green, Yellow and Red Color Scheme for Traffic Lights: In London, England in 1865 there was a growing concern over the amount of horse-drawn traffic causing danger to pedestrians trying to cross the roads. A railway manager and engineer named John Peake ...

Quite simply don't do this. False expectations are the biggest source of a disappointing experience. It commits you to features that you may not be able/want to produce, users will assume very short timescales for this functionality to be in action, and it also highlights your apps weaknesses leading users to look for these elsewhere with your competitors. ...

Handle-less doors exist in many restaurants. The idea is that you can be carrying trays/plates in both hands, and simply walk through the doors, and get where you are going (implementation note, when carrying food, you typically 'back into' the door to go through - you can't push through the door with plates of food in front of you, so, you can't see what's ...

I would progressively reveal details to a user as they need them. Consider what would your smart defaults would be? Are there assumptions that you can make that would get most users most of the way there? A couple you could consider: Sunday and Saturday are typically off days for US workers. Is this true for you? If so, then let's go ahead and default them ...

Selected – Create an inverted selection state which would make this feature more prominent. Many ways to accomplish but as an example; Make the button background black with a white or light grey pencil icon. Enabled – Increasing the contrast. Our eyes become less sensitive to light and see a narrower section of the colour spectrum as we age. Increasing the ...

This is perhaps perilously close to an off-topic icon discussion, but I think you could modify the arrow icons to make the outgoing versus incoming direction clearer. Essentially, you need to give context to the arrow: I would continue to use colour as an additional clue.

It is a general question that can be answered with a general answer: One more than is actually required by the business is too many. In other words, make sure all the required fields are essential to allow the user to progress. All too often, the required fields are only required in the sense that someone on the business side wanted the field, rather than ...

A great question! I love how UX design makes you think of these things. However, just to play devil's advocate, I can list several reasons off the top of my head why we should not have all doors as you described: Hinges: would have be to become more complex. One-way hinges, as they exist now, are a quite simple 3-piece design that require very little ...

There is at least a single benefit for those not using a mouse - Normally you are able to tab between input elements using the keyboard, this is an indicator as to which element currently has your focus.

contrast Your icons are lacking discernible contrast--both between the icon and the background, as well as between the active icons and inactive icons. Increase the contrast.

One reason for the three lights, in the UK at least, is that you have many states. Two of the lights can be on at one time, i.e. red and amber signalling that you should get ready to go, where as a single amber light would mean get ready to stop. The concept you link to doesn't cover this use case. There are also historic reasons for the 3 light traffic ...

I need to make it obvious to the user that it is a dropdown. By making it look like a dropdown. Don't make it so wide. The reason it doesn't look 'clickable' is because it doesn't look like a drop down because it's stretched across the entire width of the screen.

Delete with confirmation Delete with confirmation looks like this: Assuming the user tries to get from 1 to 3 (ie, she intended to perform action 2), the user has no interest in step 2b. We put delete-guards in place to reduce user errors, but if the action was intentional (which it is more often than not) step 2b is superfluous. Undo Undo, on the ...

I would try to use the Google Calendar approach. You spread out the days with an acceptable level of detail/resolution and then the users just drag to mark the time ranges. If a higher level of detail is required, they can fine-tune each time. It took me about 5 seconds to enter these 6 time ranges.

I think "Did you find this review is more helpful" is more precise, and attempts to solve the disconnect between negative sentiment and a "like" action. In other words, a user may really dislike a product or dislike a reviewer's writing style, quality, etc. but at the end of the day, the review was helpful in their decision whether or not to purchase the ...

If you implement the Ribbon, you are also supposed to implement the Quick Access Toolbar, where the user can add options they require. I find this useful in Office for example, where I can put common commands and not have to remember where they are on the main ribbon.

They arrange the items depending on what you search for. I.E. searching for 'Tax' is likely to return many News results, so that is shown alongside 'web': Searching for 'Mexico Flag' is likely to return lots of images, so they set 'Images' as the next tab: Whereas searching for 'Bristol' (A city in England) returns 'maps' as the next tab: ...

Digits are right aligned for similar reasons as you would right align them in a spreadsheet or a table. i.e. when you see multiple numbers (and they all have a fixed set of decimal places), then it's easier to compare the numbers with each other because the digits corresponding to each place value are in the same physical position, thus making it easier to ...

Show the true state of your application In your scenario it sounds like Scenario A - Example A is the way to go because it clearly indicates to the user which features are Active and allows them to turn off features that they aren't using. Instead of asking Which of these features do you have? simply show them what is active and allow them to turn some ...

Click button to create. Two major columns of UX design are ensuring that the interface serves the users' will, and that users are totally in control of their environment (bokardo.com says it better than I do). By automatically creating the next entity, you're making the user question what action has just happened to them and their environment. The link ...

As a counter-argument to the (well-expressed) claims already stated in other answers, confirmation dialogs should be used when an action is not performed often and difficult to reverse. A common example is installing a program on your computer: Windows machines provide this confirmation dialog any time a program requests access to your administrator ...

If a site requires that passwords only contain certain character codes, then a user will be able to enter the password into almost any device which is capable of producing those characters. If the password contains character codes which may be entered on some devices but not on others, then a user who creates a password on a device which could enter the ...

The first problem with having multiple 404 pages, each dedicated to a particular area is that you assume users were in the right part of the website at the point when they fell on to the 404. Bearing in mind that many links come from search engines and not necessarily from within the website, then I don't think you can guarantee that a dedicated 404 is ...

I suppose it's mostly a question of how much money you want to invest into your fittings. In most cases you'll have one pipe for hot and one for cold water. The knobs then just open and close those pipes – I can hardly think of any easier / cheaper solution. However there are actually different solutions that do exactly what you describe: Visiting Canada ...
