Announcing the book “User Interface”

I’m very excited to unveil my future book, User Interface, which will be released by Bureau Gorbunov Publishing.

Below are some spreads from the book.

The explanation of Fitts’s experiment opens the chapter on aiming:

Informativeness and the myth of seven elements:

One of the brilliant historic examples of how to provide instant and continuous feedback:

One of the topics is the User Interface Syntax. Here, I’m talking about a notable exception to “command equals verb” rule:

This one is just beautiful:

In the chapter “Windows” I show many examples of thoughful workspace organization:

When the user hasn’t filled a form, the main button is usually disabled. This is not always a good idea:

Hey, this is my first sponsored post in this blog. My friend Yaakov Karda asked me to tell you all about Chatra, the chat widget.

This is an ad. Text provided by client

A chat widget is one of the most convenient channels for customers to contact the company. However, many live chat widgets are still intrusive, buggy, robotic (in a bad sense) and ineffective. They are wasting people’s time ruining user experience and are just nasty.

Chatra is a different story. It has a nice and ergonomic UI, affordable pricing, it is user-friendly and helps to treat your visitors with love and care, so that they feel connected to your brand and will come back to your website next time. It can be a perfect alternative to Drift or even Intercom.

Have you ever been looking for professional support services that turned out to be inefficient and untimely? I am sure every company could do better using a better chat product.

Chatra is an effective tool to provide support, collect feedback and and avoid unwanted delays when closing a sale. It’s useful for customers big and small, ranging from freelancers and consultants and to online stores, software companies and startup that understand the value of personally connecting with their customers.

You can chat with visitors in real time (and our apps for Android and iOS help you be in touch with the visitors even out of the office), or use the offline messenger mode to collect messages and leads 24/7 and reply at your own pace.

In a messenger mode, Chatra greets visitors with avatars of your team, and our lead qualification bot not only sets proper expectations on when the visitor should expect an answer, but can also collect any required information from them in a much more effective and user friendly way than an old-fashioned contact form.

We integrate with the majority of CMS platforms, and the widget can be added to your website in just a few clicks.

Chatra stores all the visitor information and conversation history forever both for you and your visitors, so when a visitor comes back to your page, they can see previous messages and continue the conversation.

If you have several websites, you can connect them to the same account and handle all chats from a single dashboard, with no extra fee. The visitor information feature will show you which website the visitor is on, and the Groups feature allows you to assign chats from different pages to different agents if necessary.

Chatra allows you to monitor the real-time visitors on your website and initiate a conversation manually, so you won’t miss any potential leads.

You can also initiate a conversation automatically and offer your assistance on difficult pages using the automatic triggers. Triggers can be connected to various conditions (time spent on a current page or website, number of visits or pages viewed, etc.) and can work even when you are offline.

Some users are afraid of being too “intrusive” and don’t use these two features to proactively contact their visitors, and that leads to them missing a lot of potential customers who leave their website without placing an order. But the automatic triggers and visitors online list can become your greatest allies if you use them correctly. Don’t jump at visitors right away and let them look around first, personalize the texts to show the visitors that there’s a real human ready to help, and experiment with the conditions to make sure you contact customers at the right time.

Another cool feature in Chatra is the typing insights, which allows you to see everything the visitors are typing even before they send the message, so you can prepare a reply beforehand.

We also have powerful API with clear documentation, with some of its features available even on the free plan. You can use simple settings like changing the chat window size, button colors or embedding the chat window into a block on the page, or you can use more complicated things like passing custom information into the visitor information panel or integrating Chatra with third-party tools via webhooks and REST API.

So, if you have an online presence, be it a blog or professional website, get Chatra! I’m sure you are going to like it.

Group checkbox setting

Say you have an interface with a column of checkboxes.

It’s a good idea to simplify toggling of multiple checkboxes. When I press the mouse button on a checkbox and move the pointer vertically while still holding the button, all checkboxes that I’ve crossed this way should switch to the same state.

The “same state” requirement is important. If the first checkbox that I’ve pressed was turned on, all the rest should also turn on, not invert their state (as they would if I just clicked them one by one). If you have Photoshop in front of you, check out how the “eye” icons work in the Layers palette. That’s how it should be.

There’s a nuance. The standard checkbox turns on when you release, not press the mouse button. Moreover, if you press on the checkbox, then move the pointer away and release somewhere else, the standard checkbox would not toggle. To implement the behaviour described above, you’d have to change this and toggle the checkbox immediately on pressing. Usually it shouldn’t be an issue. But if the change of the checkbox’s state affects something else, maybe the change should be applied only after releasing the mouse button.

Ben Thompson on Apple versus Amazon


I mean it when I say these companies are the complete opposite: Apple sells products it makes; Amazon sells products made by anyone and everyone. Apple brags about focus; Amazon calls itself “The Everything Store”. Apple is a product company that struggles at services; Amazon is a services company that struggles at product. Apple has the highest margins and profits in the world; Amazon brags that other’s margin is their opportunity, and until recently, barely registered any profits at all. And, underlying all of this, Apple is an extreme example of a functional organization, and Amazon an extreme example of a divisional one.

Rådhuset Stockholm metro station

Previously: Västra skogen, Huvudsta and Stadshagen stations.

This is my second most liked station (after Solna centrum), Rådhuset:

The coolest thing here is this gygantic column:


Note the tunnel decoration:

All in all, an ordinary station. With ads:

Some kind of tubes:

Conveniently, there is also a bar:

Designing declarative APIs

The video of my Piter CSS conference talk “Designing declarative APIs” has been published:

I’m talking about why declarative APIs are great and give examples of their use in my own projects:

At the time of the talk, the new Jouele Pro was still in development. Now it is available.

Thanks to the conference organisers.

The new Chelyabinsk Trams diagram

Over ten years ago I made the diagram of Chelyabinsk trams and trolleybuses. That design turned out to be very successful: dozens of designers used it as a reference for building their own diagrams. It wouldn’t be as good if not for Artem Gorbunov’s generous help.

Three years ago, together with Alexander Karavaev we made a new version of the diagram. It had a lot of design inventions: the “pencil-drawn” layer for buses and trolleybuses, the “watercolour” rivers and lakes, 3D terminals, the new shape of the stops’ ticks. With that diagram, a logo for chelyabinsk trams was born: the city’s coat of arms decorated with a pantograph.

Then Polina Lesnikova joined the team. She re-drew the map to account for the changes in routes. Together with Alexander, they changed a lot of details after testing the legibility of the previous version. Thus we arrived at the new diagram:

Some landmarks were added. The bus-and-trolleybuses layer gave the previous version some visual richness, and it was interesting to scrutinise. Unfortunately, it didn’t provide any notable utility, so we decided to remove it. This helped to simplify the geometry of lines and make the fonts bigger. The new diagram looks stronger.

Designed by Polina Lesnikova and Alexander Karavaev, art-directed by myself.

Why Photoshop still matters for UI design

In Sketch, you can easily make smooth round corners instead of radial ones. Or you can easily set a background blur on some surface:

Illustration by Konstantin Dubrovsky

It’s natural to use and love Sketch. The progress should go on, routine tasks should be done instantly. But a designer who is seriously saying that Photoshop is now irrelevant, is second-class.

These features are in Sketch, because some designers had invented them with Photoshop some day.

Västra skogen, Huvudsta and Stadshagen Stockholm metro stations

Previously: Näckrosen and Hallonbergen. Now let’s look at what’s in the other direction from Solna centrum.

Västra skogen station:

The main feature of this station is these colourful mosaic patterns here and there:


If you ask Lightroom to make this photo level, it will turn in at 45°:



You may think that it’s a Stormtrooper helmet there:

But it’s actually god knows what.

Huvudsta station:

Seems to be nothing special compared to the neighbouring stations. But there is this stripe along the platform and some ribbons on the ceiling:

And a gigantic green blot, for some reason:

And some cylinders:

Stadshagen station:

In addition to blood stains on the walls, there are these pictures:

Depending on the view angle, you see different things:

Another one:

The escalators are colourfully illuminated:

The pictures are from the trip in June 2016.
