Write a summary of the comments giving at least five key features of good UI and UX design


Look at the pictures. Do you like the design of these things? Which of these things would you call perfectly designed? Which things do you think are designed badly?

Name the objects in the pictures

Listen to 6 speakers expressing their opinion about the objects in the pictures above and match the speaker with the object and their opinion

1. To tell the truth, I can’t stand it. It looks perfect but, in fact, you can’t use it! When you buy it, it comes with a slip of paper that says, «Don’t use this juicer to make juice because the acid will destroy its cover». .

2. I don’t open them the right way, but I don’t really care either way. I know that I’m supposed to tear down the middle, but I tear the tip off and voilà.

3. They are awesome! Just think about it – three turns on a piece of wire is all you need to properly secure a stack of paper.

4. I’m sorry to say this, but I just hate it! I believe the advertising slogan should be «For turning the simple act of pouring liquid into a tough challenge!»

5. They are to my liking. It is the basic combination of adhesive and a square piece of paper, but they still have no peers.

6. They are absolutely average. I know that many people hate them because they always break at the wrong moment. Well, yes, bad things happen, but most of the time when I use them, they are ok.

UI design

Clarity is the first and most important characteristic of any interface. You must generate such a design that people will be able to understand why they use it, recognise how the interface is helping them, predict what will happen when they use it, and then successfully interact with it. Clarity inspires confidence and fulfillment and leads to further use.

Maxim Shustov, Skytech

Every screen we design should support a single action of real value to the person using it. Of course, you can use two or more primary actions, but a single action makes it easier to learn, easier to use, and easier to add to or build on when necessary. Users don’t make a commitment to use the screens that support two or more primary actions.

Mila Shustova, Skytech

You must not forget about the laws of physics, no matter how strange it sounds. I’ll give you an example – the color of physical objects changes as the light changes. In the full light of day, we see a very different tree than the one outlined against the sunset. As in the physical world, color should not determine much in an interface. It can help, be used for highlighting, be used to guide attention, but should not be the only differentiator of things.

Yulia Ivanova, Skytech

UX design

All UX designers must focus on users throughout the design process. The term «user experience» itself makes it clear that your approach to work needs to center on improving your users’ experience with your product or service.

Mary Shelestova, Skytech

If you want your product to be marketable and addictive, you must keep it consistent. Users expect products to share some similarities with other products they regularly use. The more familiar your design is to others, the faster users can learn to use it, which enhances their experience. Such consistency also makes the design process easier for the designers, as they don’t have to reinvent the wheel every time they take on a new project.

Alex Rogov, Skytech

When designing, you have to take into account the user’s context. It’s the basic rule of UX design. Location is a commonly understood contextual factor — are you designing for someone on the go or for someone sitting at a desk? But there are other things to consider, including the time the user has at hand, their emotional state, the device they are using, the people who influence them, and more.

Rinat Trofimov, Skytech

The best tools for UI design

MockFlow is a suite of applications that are very helpful for a number of tasks in the typical project process. Primarily, the WireframePro app is a good alternative prototyping tool for you to use, especially if you’re testing out some new ideas. If you just need to create wireframes, then take a look at MockFlow. It’s great for working on initial ideas and enables you to build basic layouts quickly, which is sometimes all you need to get thoughts into a presentable form.

Sketch is a very popular tool within the design community that enables you to create hi-fi interfaces and prototypes. One of the great features is Symbols, where you can design UI assets and elements for reuse. This helps create design systems and keep your interfaces consistent. From there, you can easily export your design into a clickable prototype. If you are an InVision user, make sure you check out the Craft plug-in. is an incredible contender for creating lifelike prototypes from rough ideas right through to full-fledged designs. The tool also provides a lot of possibilities for your projects, including detailed animations and custom vector animations too. You can start by developing initial ideas with a hand-drawn style, then work them into wireframes and finish off with a high-fidelity prototype. The Sketch and Photoshop plug-ins really help if you want to design using other tools, but does handle the end-to-end design process well. Other features like user testing will also help validate your designs. This is an all-in-one solution with a great number of trusted brands already using it.

ProtoPie enables you to create quite complex interactions and get pretty close to how you would want your design to work. Perhaps the most standout feature is the ability to control the sensors of smart devices in your prototype, such as tilt, sound, compass and 3D Touch sensors. Depending on your project, this is a great tool for encompassing native app features. It’s easy as pie with no code required.
