In my experience a USB plug needs a bit of pressure to go in the port. It’s enough pressure to make me wary that I might break it if I’m putting it in the wrong way. After reversing the plug, it becomes obvious that it does not fit at all. This observation allows me to flip it again and now apply more pressure with confidence.

Short answer: Design commonly causes misalignment Most plugs or ports have a flared edge, beveled plug or some other design that allows for the orientation of the plug to be slightly off and still match. USB doesn't. Oftentimes, the first attempt will cause your plug to be aligned too high, slightly twisted, or some other orientation that doesn't allow it ...

Physical symmetry without symmetry of use I'm surprised that so many of these answers are addressing the consequences of poor design without discussing what made it a poor design in the first place. The issue at hand here is that the USB devices have a correct orientation and that correct orientation is indistinguishable from the incorrect orientation. In ...

The underlying problem, as I think we all know, is that the tactile feedback you get with an incorrectly oriented plug is hard to distinguish from the tactile feedback with a slightly misaligned plug. Given that, your question can be reformulated as: why do many (most?) people mistakenly assume the orientation is wrong when they actually just need to keep ...

Failure to follow the USB specification I've had trouble with USB devices that completely fail to provide the tactile indicator that the USB specification mandates: 6.5.1 USB Icon Location The USB Icon is embossed, in a recessed area, on the topside of the USB plug. This provides easy user recognition and facilitates alignment during the mating process. ...

Commercial sinks are "flat" by industrial design. There is a specific sequence for hand cleaning dishes that specifies three compartments for washing, rinsing and sanitizing. http://www.healthdepartment.org/Environmental/Food%20Scores/3%20compartment%20sink.pdf They are designed to be filled with water. They are flat to hold the maximum volume of water and ...

It's not an issue of poor design on the male USB - it's that there's no fixed orientation for the port. When I plug my mouse into my laptop, I get it right every time. But when I plug it into a desktop, there are (in general) three possible orientations for the port: left, right, up. Because of this, it doesn't feel like I can ever get it right all the ...

Trends... There has been a general positive trend over the last 15 years for designers to take on larger and larger scope of responsibilities within the product development process 15 years ago in the "Microsoft" era of formal software development, human-computer interaction, visual design, or information architecture were specific disciplines in ...

The Wikipedia article on Milk Bags point out the other countries they are common in. It also calls out the benefits (though not referenced): Milk bags use less plastic than traditional milk jugs and are placed in reusable plastic pitchers. The bags themselves can also be washed out and re-used to carry sandwiches, or to freeze food (using a twist tie or ...

I think Andrew is aligning with the mathematical idea of finding a maximum value of a function. In UX world, the function would be some combination of factors such as 'speed', 'general layout' down to 'colour of button X'. The output of such function is the UX measure. Suppose such measure depends only on one continuous factor, so we can visualise the idea: ...

Most domestic sinks (but not all) are rounded because: They are cheaper to make, as you can simply press them out of a flat piece of steel. You can't press out corners easily like this as they will tear in the pressing process. They are easier to clean with a sponge or cloth. The same applies to dog bowls by the way, which is why squared dog bowls are ...

Short answer: Yes. What you are looking for is the mere-exposure effect. It's good for many things, like for getting a girlfriend! But let's stick to logos and brands for now ;-) In studies of interpersonal attraction, the more often a person is seen by someone, the more pleasing and likeable that person appears to be. Source It has to do with both ...

tl;dr: Focus your audience on the Product's purpose In the absence of a clear product strategy, use the User Journey Map and documented workflows to remove executive opinion and self-interest from the discussion. A formula for attention deficit disorder Everything is not important at the same time in the same place. If you don't provide a clear path, users ...

Problem #1: On USB type A, there is a wrong way. This is alone is a design problem. Headphone jacks, most car keys, non-polarized 120v power plugs, and the newer USB type C connectors don't have this problem. Problem #2: USB type A lacks clear and standardized visual indication as to which way is the 'right way'. Most residential keys, grounded 120v ...

This is based on my vision, so I don't know if it's correct. but FOR ME, a Product Designer is in charge of the Product Design, whether it's a material or a digital one. This means that his tasks are more generic, and doesn't need to be a specialist in the disciplines involved in the design of the whole product, but needs to know a bit of them all. A "jack ...

Flat sinks are common in industrial settings. They're usually filled completely and so having something that holds the largest volume and where things stack easily and you have a stable surface. For the home you tend to get rounded sinks. As @Itumac mentioned it's at least partially from historical reasons. But there are utilitarian ones too. Flat sinks ...

There's a lack of a cue from the external casing: in the old days when macs used connectors with lots of pins there was a flat in one place on the circular plug which matched up with a flat on the connector the plug plugged into: If you matched the two flats together then the plug and its plug socket were correctly orientated. (And the two flat surfaces ...

People generally only buy flowers if it's for an occasion/season (eg. Birthday,Christmas) or if they want to express an emotion (eg.Sympathy, Apology, Congratulatory) The flow can be: User goes to the site and can Browse current featured/seasonal items.

The way I see it, it's a bit like docking to the Space station. There is one way to do it right. It seems easy, but a slight misalignment requires you to try again. I believe this is because , on the third try, you've become frustrated and are now paying close attention to what you are doing. That, then, makes the alignment (and orientation) correct with ...

Just selection bias at work here. You don't notice when it works correctly first time, or when you just have to flip it once. Instead you notice when due to a slight misalignment you end up having to flip it over twice.

It's cheaper to ship them. This is a case in which the monetary considerations often outweigh the usability considerations. Imagine the milk crates containing the packages. Some big-box retailers in the US started using rectangular milk jugs rather than the ones with the angled tops. They're awful to pour because they're unbalanced. Which of these do you ...

Here are some potential reasons: Security: It can be easier for staff to monitor who enters and leaves a store with a reduced number flow of customers entering the business. Safety: To affect the draft flowing through a building. Have you ever had the experience of a door in your house slamming, because of a draft? A business owner may want to protect from ...

I've installed devices that match your description in the past, and to be honest, it was a horrible user experience. If you could rely on WPS, it might not be, but then again, you cannot rely on WPS because tons of routers don't have it, or don't have it in an easily accessible way. You will need to add some other communication port to your device for ...

If users sign up without knowing the limits and you suddenly enforce them, notified or not, people will be upset. The best thing to do is inform them up front, wether you can enforce it or not.

Cost-effective structural integrity The full depth step provides the hinge point for both sides of the ladder as well as rigidity to prevent twisting at those hinges when the user approaches the top. The only type of brace that would provide the same rigidity would require cross braces and could still function as a step for those determined to hurt ...

The stakeholder owes you more information. If something is asked to be made MORE prominent, something else has to be made LESS prominent. This is like the full glass syndrome. Nothing new can be added to a fully-functioning full glass of water, without something else coming out. Simply ask them to decide what gets demoted in order to make room for the ...

I don't think there is a workflow that is guaranteed to work, because it will depend on the product, people and process (and to an extent the tools) used as to what would be the optimal workflow when it comes to efficiency. So I would suggest you try to weigh up the product (i.e. what is being delivered), people (what are they comfortable with in terms of ...

I can't really speak for others but in my case the problem usually, at least partially, comes down to the dark colors used in USB ports. In some ports the plastic part inside the socket (where the contacts are) is white and then it's quite easy to see which side of the port it's on and orientate the device/cable appropriately, but often it's black or dark ...

I think buttons are better as well because it gives the user a full understanding of what sizes are available and how the garment is sized just at a glance. For example, a dress can be sized with letters (XS, S, M...) or numbers (00, 0, 2, 4), and all sizes might not be offered (XS, 00). Even if your sizing is generally consistent, it's still helpful to ...

User research is quantitative/qualitative and attitudinal/behavioural . The decision of when to use which UX research method depends on your product stage as well as the factors listed by you. As you already have a significant amount of active users, my first question would be - What app analytics do you already have about the app usage? This falls in the ...
