Both ways seem to pose a false-positive paradigm. This can be simpler and not have to force the user to spend time making sense of the color-to-label association. Simply make the "Delete" button more prominent. Make the "Cancel" button less prominent. In regards to the labeling within the buttons, there is no need to put much context into what essentially ...

I'm not so sure you should be thinking only in terms of red and green. Red has typically been associated with danger, potentially dating back to the middle ages (citation needed). A quick Google image search for "delete" yields almost entirely red images. To me (and to bootstrap) green indicates success, red indicates danger. As deleting is a dangerous ...

Looking at this from a slightly different angle, where possible you could consider removing the confirmation entirely and switching instead to an "Do/Undo" process. This method is often used across the Google services: It has the advantages that it's culturally neutral and more efficient for the user (one-click rather than two to delete). Disadvantage ...

With all due respect, I think every answer so far has missed the mark somewhat. First of all, based on the Context section of your question ... Context Before deleting an album, the user is asked to confirm the action. ... we can deduce that this is not a success or error modal, but rather it is a confirmation modal, which implies a warning or ...

I would argue the answer is neither. Firstly, your assumption that an analog and digital clock take up the same space is wrong. Analog clocks are circular, and fit a square, while digital clocks are more rectangular, unless you intend to have an unintuitive layout. Allowing a user to pick one or the other means having wasted negative space horizontally ...

This is a similar question to the one about ATMs, and a similar approach could be adopted. Since modern machines can detect that there is an original on the glass (or in the ADF), it would suffice to prevent access to the copies until the original is removed. For that, the completed copies would have to remain inside the machine behind a door which is only ...

It depends on what is more vital for users — «love to retrostyle» or effectiveness (speed of reading without mistakes). The following illustration from Handbook of Aviation Human Factors represents how effective are digital visualizations of altitude in comparison with classic analog gauges both for expert and novice users:

It's not psychology; it's purely physical. The reason is that the perpendicular ridges are easy for pedestrians to walk on, but bumpy for cyclists; and the in-line ridges are easy for cyclists and harder for pedestrians. Note that this is at the entry of the cycle lane. It's not designed to alert cyclists that their lane is ending; it's designed to make ...

Users are more likely to think twice before clicking on something that is red. For which one of the two options do you want them to think twice before clicking? Which one of the two choices will potentially trigger more irreversible events? Source: http://en.wikipedia.org/wiki/Red#Warning_and_danger

In addition to my other method, a cheaper indication would be to have the copier beep when it's finished until the original is removed from the platen. Accompany the beep with a display message and warning light indicating the cause of the "error"1. This would also allow the original to be removed after scanning, while printing is happening (there would be ...

Design the copier so that the original is deposited with the copy. The user will already need to pick up the copy to leave or to verify that the copy is satisfactory. Updated below for books & bulky original Alternatively - a conveyor mechanism that gently deposits the book/or push it out the end where you would look to pick up your copies. You can ...

I did a bit of research after reading through your questions and the current answers, and found that there is some evidence to suggest that preference for the color red in humans, like in other nonhuman primates, depends on the whether the context is friendly or hostile (Maier et al., 2009 and follow-up studies). As summarized in the abstract (emphasis ...

How about something like this? It removes the confusion between occurring one-time and repeating once by changing the terminology. download bmml source – Wireframes created with Balsamiq Mockups Find out how your users think about this. If it's important for them to know the total number of occurrences rather than the total number of repeats, ...

Three possible solutions I can see: One Hire a barista to man the coffee machine daily, justify the cost by explaining each employee saves 5+ minutes per day not making coffee. Two Develop a disposable stirrer/steam nozzle made of high temperature plastic, you need to connect one to use the steamer and it detaches and is used for stirring the drink then ...

Not sure if this is the primary reason, but it can help partially sighted users. Tactile surfaces are used in the UK to provided information about the environment to partially sighted people. For example "blister" surface is to warm people that a footpath is ending and a carriageway begining. Further information can be found here: ...

It's a trend and, like any trend, governed by nobody. In every generation you have people who want to move away from the established, who want to renovate and innovate. Old trends come back or new trends are being formed. Flat design was a logical reaction on skeuomorphism. It's the exact opposite. In every trend somebody is the first, but that's not the ...

I would opine that this is like asking how tires could be improved in such a way as to not get dirty after driving through mud. With currently available technology and physics being what they are, I have to say this is a behavioral issue rather than a design issue with the wand itself. Your user experience can be improved by providing a pre-mixed sanitary ...

In design, the visual center is the perceived center of an artifact and not the actual center. The visual center of any page is just slightly above and to the right of the actual (mathematical) center. This tends to be the natural placement of visual focus, and is also sometimes referred to as museum height. Reference: The Principles of Design ...

From: http://www.pbs.org/newshour/making-sense/why-do-cars-have-fuel-doors-on/ Putting fuel filler doors on different sides of different cars thus means that some cars can access pumps from the left. And this makes it less likely that drivers will have to wait in line for gas. That benefit greatly outweighs the cost of occasionally pulling up to the ...

A typeface is a distinct design of glyphs, a font is a specific variant therof, consisting of a full set of glyphs. Helvetica is a typeface, as is Courier. They are different typefaces, and by definition different fonts. Helvetica condensed bold is a font, as is Helvetica italic. They both belong to the Helvetica typeface, but they are different fonts.

I think the best explanation I have found was in this article which explains how fonts constitute a typeface. To quote the article A typeface is a family of fonts (very often by the same designer). Within a typeface there will be fonts of varying weights or other variations. E.g., light, bold, semi-bold, condensed, italic, etc. Each such variation ...

I agree with your colleagues. Any good coffee shop will keep two clean, wet cloths (bar towels) by the station, one for cleaning the machine and one for wiping the steam wand. Cleaning and purging the steam wand after is essentially barista 101; if you don't know to do that and have no one around to guide you, you probably shouldn't be operating a ...

What is the existing standard in the rest of your application? Do you use red buttons to indicate "I want to complete this action" and green ones to mean "cancel this action"? Or is it the other way around? If it's anything like, well, pretty much every piece of software I've ever seen, then my money's on green for "go ahead and do it" and red for "abort! ...

Another solution (along the lines of @JohnGB's answer but with no supplemental cables needed) is to use a newer type of power strip that can accommodate large AC adaptors without blocking other outlets. One novel design is the Quirky PowerPivot that bends not only to accommodate large power "bricks" but also to fit in your space neatly:

Early speed camera designs made use of radar beams only. These have been shown to provide reading with high errors, sometimes ridiculous ones. In some countries, like Israel, this has resulted in a legal turmoil, where at some point (with the help of specialised legal firms) not a single offender was convicted in court. This has prompt a revision to the law ...

I think you're mixing up logo and icon. A logo doesn't have to be a square. There are several examples of famous non-square logos. But an icon should be square. It is mostly used as gravatars or also favicons (the small images in the browser tabs). But there is a strategy to design your logo similar to your icon. That means that your icon is also used in ...

It may depend on how the time is used. If it is needed for accuracy, then digital is a better choice. It is possible to get an accurate read from a digital display without having to look at and interpret the hour hand, minute hand, and second hand (all separately). If, however, the clock is used to show a quick estimation of time, analog might be ...

@Andrew is spot on to say that the ATM design is the right way to think about this - you get your money last, since that makes sure you don't forget to take your card. So I'd separate the scanning part of the process from the printing part. So first off you put your original on the scan bed, press a scan button to scan, remove, add the next sheet and so on ...

Suggested solution: How should I visually represent multiple three-state flags? The complication is that each flag has three possible states Means there are only two states "on/off" for the component, but component itself can be disabled or enabled. So it is enough to have two state switch. Having that understanding it is possible to throw ...

I wrote about some deliberations that were made over design and usability of responsive lightboxes. The main things to keep in mind are: Be aware that lightboxes are intrusive! Only use a lightbox if there's no other way to showcase a piece of content. If you must use one, make it as easy as possible for the user to understand that they're still on the ...
