Does the formal specification of UX require special language outside of general specification languages?

I'm a fan of Alloy and CASL specification languages ​​and my question is: what is the common practice for formal UX methods? Does UX require separate specification languages? Generally, any specification language can be used to describe: 1) the graphical presentation of the screen and the available commands; 2) the content of the available commands. UX gives only additional constraints on the specification, some non-logical guidelines (external, empirical) of the content of the specification. Or am I wrong and the IT community has special methods for modern web / mobile / TV / device / portable graphics programming and modern UX programming?

terminology – DesignOps in organizations with high UX maturity

Now that we've moved from ResearchOps to the whole design process (DesignOps), is this a function that has been successfully implemented in what I assume are very mature organizations with UX?

I am interested in how mature design organizations have been able to operationalize their design process to integrate and work with the organization's business and software development branches, or if it is simply a concept described as the next step / trend. for organizations focused on design.

Has anybody met organizations that have a DesignOps feature? Where is the organization hierarchy and how are the teams and roles defined?

authentication – correct UX for the scenario when a user forgets the answers to his security questions?

You use security issues effectively as a second factor.

Two-factor authentication

Two-factor authentication (2FA) is used to make it more difficult for attackers to obtain credentials. You may have seen them in great services like Amazon in two steps or Google. It makes good sense to use them if money is at stake.

Please read the Wikipedia article on multi-factor authentication for more details.

Security issues for 2FA

Best suited in another context, see 2-factor authentication vs Security issues

Security questions for "forgotten password"

Security issues make sense to prevent your users from being followed by others through the "forgotten password" feature. Here is a little user story that works:

Anna is on GitHub. Her username is her e-mail address, which she also uses to sign her commits and that she also publicly in her profile.

Anna is fighting with Bob. Bob knows that Anna is on Github and wants to annoy her. It triggers GitHub's "password forgotten" function every hour to distract Anna.

Let's say that GitHub allowed Anna to ask a security question (if she wishes). Then the story would look like this:

Anna is on GitHub. Her username is her e-mail address, which she also uses to sign her commits and that she also publicly in her profile. Since she has already received "forgotten password" emails, she asks the following security question: "What is the second name of my wife's mother?" Two people in his family know it, but it's not public information.

Bob knows that Anna is on Github and wants to annoy her. It triggers the function "password forgotten". He is asked "What is the second name of my wife's mother?" He googles for this, but does not find this information. Anna is not disturbed.

ux designer – How UI / UX design works for Android apps


Android has different layout styles; it is easily possible (and always recommended in any case) to make relative layout files. Meaning, based on percentages, etc., to look alike on different screen resolutions:
overview of Android layouts

This means that you must provide accurate information on all sizes and margins, either in percentage or in absolute numbers.

What are you as a designer make need to provide are different sizes for the pictures:

overview of different scales for images

This helps the developer a lot if you create the images in properly named folders, so he can just copy and paste them into the project. From this question SO:

The folder names must be:

  • / drawable-ldpi For low density displays
  • / drawable-mdpi For medium density screens
  • / drawable-hdpi For high resolution screens
  • / drawable-xhdpi For very high resolution screens

More on this here:
size of the image (drawable-hdpi / ldpi / mdpi / xhdpi)
Supports different pixel densities

ux designer – How u design works ux for Android apps

How does a designer ui / ux offer Android app designs? As far as I know, a designer will provide a psd file to the developer. But Android apps have different screen sizes. So, how does the developer get the image / icons required in different sizes?

In addition, does the designer need developer guidelines on sizes or ratios? For example, this icon should be that size.

Or does the designer only give one psd and the developer converts them for different screen sizes?

mistletoe design – Ux ideas for the multiple entry search bar

I'm trying to create a search bar that can search for multiple keys and values. An example of use will be "type: car, model: toyota". Available keys will be autocomplete. My initial idea was that once the user started typing to view the available keys, once he has selected one, add the selected key to the input with a & # 39;: & # 39; as:

enter the description of the image here

everything you write after the & # 39;: & # 39; will be the value. Once you entered, I thought I would cheat a token with the key and value entries and repeat the process. You will have at the end of your key / value selection a list of bullets created based on your entries that will be used for the actual search.

My concerns are:
– Is it a clean way to do that?
– Do you know of sites that have a similar search behavior and on which I can inspire?
– How to handle a long list of parameters (note that the search bar has a limited width and height in the page)?
– Do you have any other suggestions on how to approach this?


usability – An alternative to sliding in panels that does not compromise UX?

We are developing a company-wide Web application in which some screens contain maps that contain certain information and can be clicked. By clicking instead of a modal, we have currently integrated a slide from the left pane in which additional information and editing functions are provided to the user.

We envisioned another way to present and provide the same information rather than the current slide style, as they have been used for a long time and seem old and out of time.

I just wanted to know if there are healthy alternatives that do not compromise UX or Look [UI].

thanks and greetings

Does everything look / work as expected? Why or more importantly why not? Any other idea or recommendation would be greatly appreciated!

Thanks in advance!

Ux field – Can we open the keyboard if the mobile application has the status of backsheet?

I am working on a mobile application. It's like ordering an app for the grocery store but wholesale and not at the retailer. Thus, the user can order from 100 kg to 1,000,000 kg for sale. The range of commands is huge and because of this need UX help

I am a user and I can order between 50kg and 1.00.000 kg. I select a bag containing 50 kg. But if I give the possibility to add elements whose design is inferior to the design, it will be very difficult to add 20 to 100 bags because the user will have to click 20 times.

enter the description of the image here

I decided to give some text, but I'm not sure that the background sheet mode is already activated. How can I open the keyboard for all users to enter a specific value?
Need help for Ux design.

Plus – I've redesigned the pop-up but it's a bit complex as in the picture below.

design process – How does a UX designer work in a data science project?

I am a UX designer in a research team on AI in the banking system. We run half of the projects focused on data science and half of the research on AI.

Most of our projects are based on credit or customer score forecasting, financial distress forecasting, etc. Rather, they are projects focused on data science. I am the only UX designer on our team. It is interesting to participate in the data science project and to learn new things. However, I had no experience working with data scientists.

The main difference between a software development project and a data science project is that, for a software development project, we build elements that meet the needs of the user, and there is always a delivery . However, in the data science project, we do not know if it is possible to predict something because scientists have to experiment and try to find the information from the data. Data science solutions do not always come with a delivery.

I found that it is relatively easy to identify the users of a software development project because we have specific requirements to define, while it is difficult to ################################################# 39, identify the users of a data science project, because sometimes people just want to see if it is possible to do something. with data science, the target is so ambiguous.

Most of my work focuses on designing dashboards in analysis tools such as Tableau, as a designer of UI. Sometimes it's also repetitive, I'm tired of these things. I want to do more interesting things, such as researching users, knowing what they think, how they behave and then experimenting.

Here is my dilemma:

I am interested to work in such a data science team, however, I do not know how to work with data scientists and what is my role as a designer in the data science project in addition to one? user interface designer.

Does anyone have this experience and share some of your ideas or ideas with me, please?

Thank you πŸ™‚
