From these screenshots, there are 3 functions in that part of your app. List of meetings, with search functionnality Meeting creation, with several steps Inviting people Apparently this menu is displayed on the list/search page? (I will assume so in the rest of the answer) A few points, not really ordered: It is not clear where we are. The title ...

A few things about your question and some next steps: User Experience Experts are just people that swallow their pride & know to ask their users / customers. I'd like to think my experience gives me a solid base for presenting better-than-average first-shots, but I know that users ultimately control the direction of my work. I wouldn't necessarily ...

It's not about whether or not to follow trends just because Facebook has done it. No doubt, Facebook has likely done loads of user research on what is more intuitive for most of their users. Source: How does something become "common knowledge"? You should do your own research to see what makes the most sense. In your case, the best way to ...

I guess you should use the first option including items filtered by only two tabs : - My pasts events - All (default view) In this last one you should include all the available events and those user participates to (this case assumes a different design from all the availables for instance different colors and/or a personal calendar view).

I've just thought about this way: or this way: It sounds far more explicit.

How about this? Group is not redundant and also in line with the options.

I would also suggest you carefully consider the order of the values. Ordering values from 10 to 1 (instead of from 1 to 10) leads users to give an higher average rating (you can find more informations in this answer I wrote a couple of days ago). You may also want to have a look at the primacy effect: a cognitive bias that results in a subject ...

Avoid abstracting the label from the control wherever possible. That is, avoid separating the control and the label that describes the control's state because that forces the user to look in two different places in order to understand what's going on. Instead combine them so that the control clearly describes its own state. In this particular situation, I ...

I am assuming you are not using a graphic designer because for some reason that resource is not available to you. However, even if that is the case, you may still be able to accomplish your site redesign using one or more of the many "yearbook" or "best of" design books available through bookstores or online. I am not a graphic designer, but I have found ...

Slightly off topic - The nicest feature I've seen on this kind of site (if it allows online 'discussion') is an 'Ignore' Button so that users can choose to ignore the postings of a particular user (their posts then show afterwards as 'Ignored User'). This adds a "pre-reporting" stage so that users who post content which could end up producing more heated ...

One book I'm going through now is Interactive Design by Andy Pratt & Jason Nunes. It focuses on UX in general, but introduces you to UX practices and methods through real-life examples, which in turn gets you thinking about how to consider it in your own application. It covers some design principles, such as Affordance" and gives concrete examples of ...

I am not a big fan of the "5 star" rating type of systems because... What on earth is a 3 star? What does that mean? Instead, I am a fan of the "It works well" or "It doesn't." Reason why I say that is because pay attention when you ask someone a question along the lines of "what do you think of this book" or "are the servers fast for your website ...

Depending on the questions asked, rating values can become quite burdensome in terms of cognitive load. When the user is asked to rate a property of your system, they are generally not asked for a precise measure, but an estimate or a perceived value. Can you always confidently tell the difference between something rated 2/10 and 3/10? What about 7/10 and ...

Sparling and Sen did research on rating systems titled "Rating: How Difficult is It?" trying to answer the question of how to choose the right scale (Like [unary], Thumbs Up/Down [binary], 5 Stars, Slider 100 points). You have to weigh the time it takes for each scale to be understood, interacted with, and then satisfaction. Really great paper. In short, ...

One approach that tackles the problem, perhaps counterintuitively, is to use a slider. The user actually has infinite (or near-infinite) granularity, but without having to make an agonizing decision between 7 and 8. Visually, this option is very simple, as there is only a single line with a single button. If you absolutely need the data to be on an 11-point ...


5

If you do want the granularity of a 10-point scale, have you considered using half stars? This gives the compactness of having 5 options, with the granularity of 10.


12

To avoid the "somewhere in the middle"-answers one could also use a four point scale, which makes responses more accurate on for-votes and against-votes. This is especially useful if you want to make it very clear if users like or dislike a statement. While survey research scales may range from two to ten points or more, researchers have generally ...

10 seems quite a wide range for what is essentially a 'do I like this' poll. Does it really make a difference if Fifteen people rate Availability at 7 and Thirty people rate it at 8? I'm not sure you really need that much accuracy in such a subjective poll. Why not use a standard 5-point Likert scale? (Image from the Wikipedia article.)

You must have a clearly marked exit (Jakob Nielsen - Usability Engineering). You should have two buttons labeled "OK" and "Cancel". Do NOT add an "X", to avoid confusion.

Where budget is zero and actuals is zero then the difference (delta) should be zero! There is no difference between 0 and 0. Where budget is zero and actuals is high then the difference (delta) I think it looks great by stating 'Infinity %'. It is truthful, concise, meaningful, elegant, non-symbolic, not cryptic. Good framework, have a biscuit! Where ...

From a user perspective, I would prefer a blank cell, if it is clear that this cell is computed by dividing Budget by actual. Background: Adding a long text adds a lot of noise to the grid, especially when no budgets are frequent. You might add a tooltip like excels blue green info mark, which shows "could not be computed, because the budget is zero"), but ...

Why can't you demo it to some of your users, and ask them to say what they think? They are two different situations though, and a N/A may be confusing. Infinity is right for x/0 so long as x is not 0. Look at the graph of 1/x. As it gets closer to 0, the group explodes to infinity. As a limiting value, 0/0 is indeterminate meaning it can be anything. ...

It hasn't as much got something to do with whether "people like it or not". It's not a "certain percentage that likes it" or doesn't. It's about location awareness. By jumping to the content instantly, it might as well be a really quickly loaded new page. The user wouldn't know the difference. By scrolling slowly to the bottom of the page you show that, ...

I would use some small-styled text saying "DIV0" or "INF" / "∞", in a gray shaded box background with some negative space around that. It should look like an icon to show it's not a typed or calculated value like the rest. But the message can still be read clearly so that the relevance of the problem is apparent without having to understand some generic ...

You could use an exclamation mark icon that shows a tooltip on hover to explain exactly, what it means and what is missing / what value is bad: download bmml source – Wireframes created with Balsamiq Mockups

Either: Give a cause - a couple of words stating why the calculation cannot be made. Use an error string - as other have mentioned, take examples from Google sheets and Excel. Check the result - when you do the calculation, if the result is NaN or Infinity, display N/A instead. Add a help link - a small '(why?)' or '(learn more)' next to the error that ...

A common solution for table cells that are not available or applicable in certain situations (such as your %Δ for a budget of 0) is to use the placeholder text n/a (or N/A).

Most spreadsheets (OpenOffice Calc, Microsoft Office Excel, and Google Spreadsheet) will handle these cases displaying a non-blocking error akin to "division by zero": I think this is the best behaviour, because it does fill the field with something meaningful to the user, but at the same time it doesn't "stand out" too much and compromise the overall ...

You might consider having a word with the users and ask what they think they should see, though be careful, their initial reaction might be 'zero', which is DEFINITELY not right in any mathematical sense. I personally would leave the output blank, or perhaps use the term 'undefined'. If they really want to see a symbol, then I think you could safely put the ...

You could try to use a short description of the actual cause, e.g. no budget

Just because the medium changes doesn't mean visual balance no longer applies. Because web apps are in a browser and browser sizes vary depending on the user, it is a bit different when comparing it to print media, where the designer knows explicitly the dimensions of the final product. Design is not an exact science, but setting appropriate css rules with ...

Simply give an option for a user to choose how many questions should be displayed at once. This will give user "Control and Freedom"

The best approach is to support both leave the decision as an option to the test writer. Some teachers prefer one over the other. Some teachers also may want to control whether or not the student can navigate to previous questions.

I've designed both formats of quiz. Which one is better depends on the situation. Both formats tend to be equally doable from a technical standpoint. Situations where I've found all questions on one page to be better: When the user is allowed to answer the questions in any order When information from one question helps the user answer another question ...

It's better to show the questions one by one or group by group. Because the user can focus on the question. Bytheway It's better to already load all the questions And you should have a progress bar. I tested this method. It works great and we had positive feedbacks.

You need to consider the form-factor the users will be using and also avoid latency between questions. Displaying sequentially can reduce the "clutter" and would work better in many situations such as smaller screens, but should be done dynamically client side if possible to get near instant transitions. Loading new content from the server on every press ...

I tend to prefer a stepped process as long as there is a clear indicator of progress. So, something like "Question 1 of 5" then "Question 2 of 5" and so on. To me, it's distracting to have all the questions on one page. I find myself drifting between questions.

Unless users should be allowed to arbitrarily create new codes through the same interface you'll want the interface to provide the available codes to the user, either a full list of all available codes or through a full or partial auto-complete functionality (like assigning tags to questions here in the stack exchange.) Unless there is need for extended ...

Your example solution requires the admin to remember a list of relevant codes & what they mean/who they are linked to. I don't know about your specific users, but most people are not very good at recalling number codes. If the list of code is short enough, consider displaying a table of these code. download bmml source – Wireframes created ...
