Package Contents

But first, let’s traditionally take a look at the packaging and contents. The mouse box is blue and small in size. On its front and back sides there is an image of the product and its four main advantages are listed in several languages – low weight, optical Hero sensor, LIGHTSPEED wireless technology and economical battery power consumption. Technical specifications can be found on the left side. Inside, a cardboard damper and a bag are provided for protection against damage.

In addition to the mouse, the package includes a 1.5-meter USB 2.0 extension cable for connecting the receiver, warranty information, a brief user manual, a receiver and one Duracell AA battery.

Appearance and Design

The Logitech G305 has a fairly simple streamlined and symmetrical shape, which generally follows the contours of the G102 and G Pro. The mouse is medium in size, not small, as it might seem at first. The top panel is made of smooth matte plastic, which is quite resistant to dirt. The G logo is applied in gray paint on the back. The LMB and RMB panels are separate, with Omron switches with a rated life of 10 million clicks located under them. In addition, these panels are spring-loaded, so they have no backlash and quickly return to their original position. In terms of pressing force, they are quite light, with loud juicy click sounds. Between the keys is a glossy insert, which contains a scroll wheel, a small oval DPI change button (light, with a muffled click sound), a dot indicator of the current resolution and battery level.

The back of the top panel is removable by pressing it lightly in the center and sliding it back. Under it is a centrally located compartment for a single battery, next to which is a pocket for the receiver. Under the top cover there is a soft spring insert, which provides good battery pressure. The weight of the empty mouse is 74 grams.

No matter how remarkable and stable wireless communication the LIGHTSPEED technology provides, no one has canceled the laws of physics. The greater the distance between the receiver and the transmitter, the greater the delay in signal transmission and the more the signal is interfered with by extraneous radio interference in the now overloaded 2.4 GHz range. Therefore, the kit includes an extension cable for the mouse receiver, which allows you to place it next to the rug and minimize these problems. Ideally, the receiver should be located less than 20 cm from the mouse and no closer than 2 meters from other wireless devices, such as a Wi-Fi router.

The left side is made of rough plastic. In the middle, in the upper part there are two narrow glossy side buttons. They are easy to press and have a clear sound when triggered. The buttons have no free travel.

In the front view, you can see that the main keys have recesses for the fingers. The fit of the parts is good. The scroll wheel is rubberized, with even transverse notches. It rotates quite quietly, has clearly defined fixation positions, well distinguishable tactilely. The middle button is pressed hard and quietly.

The right side of the mouse is the same as the left, but without the side buttons.

The stern of the mouse is streamlined and rounded. It fits comfortably in the base of the palm with a “claw” or “palm” grip.

Logitech G305 is well suited for all major types of grip and will be equally comfortable in both right and left hands. The mouse is most versatile for small and medium hands, while owners of large hands will probably prefer to use it exclusively in a finger grip.

On the bottom of the mouse there are four oval Teflon feet at the corners, a pad around the sensor, and another small round foot at the back. There’s also the power switch located here. In the center is the window of the Hero optical sensor with infrared backlight.

We decided not to open the manipulator, as many video reviews on how to disassemble this mouse are readily available online. And there we noticed one interesting peculiarity. The Hero sensors in the Logitech G305, G Pro, and Pro Wireless look completely different, even though they are called the same. And the sensor from the G305 most resembles the shape of the microchip and the external backlight diode to the mysterious Mercury from the G102. As for the Hero sensors in the G Pro and Pro Wireless, although they have backlight integrated into the microchip, they also differ in appearance.

Fortunately, the mouse lacks RGB backlight elements to save battery life, and the only thing that can light up on it is the dot indicator in the middle. It doesn’t shine for long either, but it shows in color what mode the mouse is currently in (when turned on), which level of resolution is selected, and how much battery life is left.

Software

To configure the mouse, users can choose between two Logitech G305 software options. The first is the traditional universal Logitech driver, and the second is the new Logitech G HUB driver, which is still under development and testing. Both software can even be installed simultaneously, although in this case G HUB will have priority until it is removed. That’s why we’ll talk about it.

From the main screen, there is quick access to selecting a device, changing profiles, program settings (upper right corner), account (lower right corner), viewing news, and accessing the official website (feed below).

If desired, you can create your own account to access the cloud storage of profiles. The mouse supports one built-in memory profile. To edit it, the program needs to be granted access. In LGS, everything was a little simpler in this regard. After enabling the mouse, we get access to the assignments of any of the six keys. The set of allowed commands is standard – keyboard and mouse clicks, Windows functions, and macros. It is possible to set alternative commands that will be activated in G-Shift mode when the button responsible for it is pressed.

The macro editor looks quite funny and allows you to record a sequence of commands from the keyboard and mouse, taking into account delays. After recording, you can choose one of four ways to play back the macro command. The positions of the mouse cursor and the direction of the scroll wheel are not fixed by the application. Text and emojis can be added directly to the body of the macro, a link to start an application, a system command, or a delay can be embedded.

In the sensor settings, you can choose up to five sensitivity levels in the range from 200 to 12,000 cpi with a step of 50 cpi. To quickly select a specific level, you can assign the “SHIFT DPI” key. The polling rate is selected from options of 125, 250, 500, and 1000 Hz, but this is only available in high performance mode. If the mouse is switched to power saving sensor mode, the polling rate is fixed at 125 Hz.

In profile management (tab in the center at the top of the main screen), you can link a profile to the start of a specific application, create a usage scenario for it, assign a basic profile, and add necessary macros to it. And this is what the G HUB settings window looks like. Here you can select its launch and operation parameters, interface language, and you can also update the program or view its manual. In the “My Gear” section, you can select parameters for supported devices, and in ARX Control you can configure pairing with an external screen or mobile device to display program data on it.

Ergonomics and Testing

Testing of the Logitech G305 Lightspeed mouse was conducted on a black Mionix Alioth M single-color fabric rug. The receiver was located directly next to the gaming surface, according to the instructions. Compared to what is now considered “gaming mice,” the G305 looks a bit primitive, like a guest from the past. There are no rubber or metal inserts, soft-touch, multicolored garlands, and aggressive shapes. Everything is extremely ordinary, and if anyone remembers the Logitech Pilot mice from the early 2000s, they will definitely notice the similarity. But behind all this lies reliability and functionality. The body is assembled strong and light at the same time. The weight of the mouse with battery is 96 grams, and it is perfectly distributed along the axes of symmetry so that the manipulator does not tip over when lifted from the surface. The mouse panels feel good in the fingers and are resistant to dirt. The performance of all keys and the scroll wheel can be called excellent – they are clear and responsive. The main buttons are additionally spring-loaded. The feet here are not particularly slippery, and overall the mouse has low inertia.

In terms of connection stability, everything is also very good. During work and games, both in maximum and reduced performance mode, I was unable to feel any lag or delays. This mouse cannot be distinguished from a wired one without special devices. The mouse has a sleep mode after a few minutes of inactivity even in game mode, but the power saving is not aggressive, and to wake it up it is enough to slightly move the manipulator, while the cursor freezes for literally a fraction of a second. Continuous activity mode is not provided here, so this option of automatic saving can be considered an acceptable compromise.

If the mouse is used at minimum settings, its charge will last approximately 9 months of active daily use. But at maximum settings, the battery life is up to 250 hours, which is about a month of gaming for 10 hours a day. Thus, gamers will have to buy not only a mouse, but also a decent rechargeable battery, or even two, if they don’t want to use a cartridge of batteries throughout the year (especially since after a year the rechargeable battery will fully pay for itself).

Regarding the operation of the Hero sensor (in the modification that is installed here), I have no complaints. It differs little from the PMW3360 in performance, supports high speed and accurate cursor positioning. It is also impossible to cause cursor breakdown on it, and there are no parasitic features like acceleration, excessive smoothing of the trajectory, and angular binding. The only difference is the inability to adjust the lift-off height, here it is fixed at slightly less than 2 mm. The ideal resolution range, from my point of view, would be the 800-2000 cpi segment.

Verdict

The Logitech G305 Lightspeed is a high-quality and durable, albeit simple-looking, wireless gaming mouse that is a wireless version of the Logitech G102. Its advantages include an excellent optical sensor, a strong and balanced body, low weight, good keys and scroll wheel, stable lag-free connection, and long battery life. I couldn’t find any significant flaws in the G305 that could spoil the impression of working or playing on it.

However, the recommended price of this mouse seems overpriced, even against the background of other products from the company, not to mention competing solutions. After all, it is worth considering that in a gaming scenario, the buyer will also have to purchase a couple of rechargeable batteries and a charger for them. As they say, good, but expensive. However, if the convenience of the absence of a wire is above considerations of economy, and the shape of this manipulator fits your hand, then the Logitech G305 Lightspeed is a worthy choice.

What contributes to the success of an e-commerce enterprise? A broad and diverse product range, multiple payment options, accessible and efficient customer service through various platforms, and punctual delivery? 

Yes, all these factors play a significant role. But, equally important is an intuitive and aesthetically pleasing website, as it’s the user’s interaction with the site that can truly set you apart.

In this article, we will delve into the concept of user experience (UX) design, identify eight UX design blunders that can wreak havoc on an e-commerce business, and provide recommendations on how to prevent them. But first, let’s clarify what UX design means and outline its primary advantages for online businesses.

Understanding UX Design and Its Fundamental Principles 

There are numerous interpretations of UX design. Simply put, every way you interact with software, whether it’s a website or a desktop/mobile application, from the number of clicks needed to reach a specific page to the positioning and size of a button within the browser window, forms part of user experience design.

Typically, users rate a software product higher if it’s…

… user-friendly

… visually appealing

… beneficial to them

A UX specialist’s objective should be to design an app or website that fulfills these basic criteria. In essence, the ultimate aim of a UX designer is to augment user satisfaction with a software product by enhancing its usability, accessibility, and appeal.

To realize this aim, UX designers should adhere to the following fundamental principles:

• Be human-centric. Software should be designed for people, not machines. Interactions with an app or website should resonate with humans. Computer language should be reserved for computers.
• Be straightforward. This implies maintaining uniformity in the design of website elements and highlighting the more important/less important elements through visual hierarchy. 
• Be context-aware. Users should always know their position on a page or the entire site. Breadcrumb navigation is one way to provide this context. Be discoverable. If website content is not sorted into categories, sections, or other logical divisions, users will struggle to find the information they need. This discourages them from searching further on the site. It’s akin to a library where books are not arranged alphabetically.
• Be uncomplicated. There should be no diversions, i.e., anything that distracts a user’s attention from your primary action. This includes distracting fonts and colors, moving images, additional high-contrast CTAs, etc. Also, use simple language and avoid industry-specific jargon.

Violate any of these principles, and you enter the danger zone. Adhere to them, and your likelihood of success escalates. Here’s why.

The Impact of Effective UX Design on an Online Business 

Boosting Conversion Rates

The online marketplace is fiercely competitive. Imagine you’re searching for a pair of shoes and come across two local websites selling footwear. On the first site, your search for a specific model turns into an ordeal. The website is disorganized and challenging to navigate, and the search results bear no relation to your query. In contrast, the second site immediately displays the exact model you’re looking for.

Which of these sites are you likely to patronize? The choice is clear, and other users would likely make the same decision.

Enhancing SEO Rankings

Google frequently updates its search algorithm, but one constant factor it values is user experience. As a company that cares about its reputation, Google prioritizes websites with superior UX design in its search results pages.

Generating More Leads and Maintaining Existing Customers 

A user-friendly website doesn’t just attract new visitors. It also facilitates smooth interactions, helping businesses retain their existing customers. Effective UX design builds trust in a brand, service, or product, fostering long-term customer relationships. A loyal customer is a consistent revenue source.

To reap these benefits, pay close attention to your online store’s UX design and avoid common mistakes that contradict the principles discussed earlier.

Potential UX Design Pitfalls for Your Business 

#1: Overly Long Forms 

Forms can be an effective tool for gathering customer information. However, their usefulness depends on their purpose. If you need to ship a product to a customer, the form must collect sufficient details to ensure accurate delivery.

Conversely, if a customer is merely downloading an ebook, there’s no need for a physical address field. Remember: the more fields a user must complete, the more likely they are to abandon your site.

Recommended Actions

• Think carefully about what information you need from users when designing forms. Review each form and retain only the most relevant fields for each scenario. 
• Ensure your form fields are sequential and organized. You can achieve this by categorizing them or arranging them in an ordered list. 
• Consider using autocomplete features to simplify the form-filling process. This feature presents a list of options beneath an input field (like the Google search field), allowing users to select an option rather than typing out the full word or phrase. Other beneficial features include date pickers and dropdown menus. 

Ultimately, use any strategy that minimizes the time users spend filling out forms.

#2: Excessive Textual Content

An online store is primarily for selling products or services, not reading. Overwhelming users with text can deter them, as they’re typically disinclined to read lengthy paragraphs.

Recommended Actions

• Reduce the amount of text on your website. Review all content and retain only what’s absolutely necessary. 
• Use ordered or unordered lists instead of long passages.
• Avoid extending your text across the full width of the content section of a page. Ideally, a line of text should be no more than 60 characters long. 
• Divide your text into small, digestible paragraphs. Research shows that people can retain between 5 to 9 items in their short-term memory. Beyond this, they can easily lose focus. 
• Ensure your text is divided into paragraphs with a maximum of 9 lines each. Wherever possible, substitute text with visuals. A picture of a desired product is likely to prompt a purchase more effectively than a textual description would. Most people are visually oriented.
• In addition to photographs, consider incorporating infographics, videos, animations, and other visual elements. However, ensure these graphics are web-optimized as high-resolution images may significantly slow down page load times.

#3: The Overwhelming Onslaught of Popups

“Join us!” “40% off this July.” “Subscribe Now!” It’s incredibly frustrating when popups obscuring the content you want to see continuously appear with every link click. Popups are a leading contributor to high bounce rates.

Recommended Actions 

Avoid irritating your customers with an excess of popups. Instead, locate an area on the page where they can appear without disrupting your visitors’ activities. Also, allow your users some time to engage with the content before presenting them with a popup request.

#4: Overcrowded Content With Minimal White Space

Attempting to pack too much content onto a single page without sufficient white space is ill-advised. It makes it difficult for visitors to distinguish between crucial elements and those of lesser importance. As a result, they may overlook key components like call-to-action buttons.

Recommended Actions 

Ensure there is ample white space around elements to help your audience focus on the most important ones and prevent your page from looking cluttered.

#5: Inadequate Contrast 

Low contrast between the background and text is a significant UX faux pas. While it might be used artistically in some scenarios, clear contrast is essential for product pages. This is especially true for online stores targeting seniors who often have compromised vision.

Recommended Actions 

Experiment with various contrast settings to find the optimal one. Get feedback from friends and colleagues about the readability of your content. There are numerous online tools available to assist you in selecting the best contrast.

#6: Excessive Navigational Layers 

While providing your current or potential customers with many options is good for business, it can adversely affect user experience. An abundance of menus and submenus can quickly overwhelm even the most patient visitors.

Recommended Actions 

Ensure your most valuable offerings are easily accessible within a few clicks. Secondary or optional items should have their own dedicated area on your website. Make it easy for visitors to find what benefits them the most.

#7: A Jumble of Fonts and Colors 

Remember, simplicity is key in UX design. An overabundance of colors and fonts can render a website confusing and divert attention from key actions you want users to take.

Recommended Actions 

Restrict your color palette to two or three harmonious colors. You can use this tool to find the best color combinations. Limit yourself to a maximum of two consistent fonts throughout your site. 

#8: An Unnoticeable CTA Button 

The call-to-action button is arguably the most crucial element on an e-commerce website. It’s the click on this button that generates revenue for your company. However, it’s not uncommon to find websites where the CTA button is hardly noticeable, overshadowed by surrounding elements.

Recommended Actions 

Ensure your CTA button stands out by selecting a unique color, design, and wording that distinguishes it from the rest of the page elements. The placement of this button is equally important. 

Final Words

To sum up, enhancing user experience on your e-commerce website is a multi-faceted task that requires careful attention to several aspects. 

Simplifying and optimizing form-filling processes, reducing text overload, wisely handling popups, providing ample white space, ensuring adequate contrast, minimizing complex navigational layers, practicing restraint with fonts and colors, and making your call-to-action button noticeable are all part and parcel of creating a user-friendly interface. 

By addressing these key points, you can significantly reduce bounce rates, increase user engagement, and ultimately drive your online store’s profitability.

Setting Up and Managing Database Connections with UniDAC

Creating and managing database connections is a crucial part of any database application. With UniDAC, this process is simplified and streamlined. Here are step-by-step instructions on how to set up database drivers and manage database connections with UniDAC.

Setting Up Database Drivers

1. Install UniDAC: Before setting up database drivers, ensure that UniDAC is installed in your development environment. You can download it from the official Devart website and follow the installation instructions.
2. Choose the Database Provider: UniDAC supports a wide range of databases. Choose the provider corresponding to the database you are using. For example, if you’re using Oracle, you would choose the Oracle provider.
3. Configure the Provider: Each provider has a set of properties that you can configure to suit your needs. These properties include the database name, username, password, and others. Configure these properties according to your database setup.

Managing Database Connections

Create a Connection: To create a connection, instantiate the TUniConnection component. This component represents a connection to a database.

    var
    UniConnection: TUniConnection;
    begin
    UniConnection := TUniConnection.Create(nil);
    end;
	

Set Connection Properties: Set the properties of the TUniConnection component to match your database setup. The ProviderName property should match the database provider you’re using. The Username, Password, and Database properties should match your database credentials.

    begin
    UniConnection.ProviderName := 'Oracle';
    UniConnection.Username := 'myUsername';
    UniConnection.Password := 'myPassword';
    UniConnection.Database := 'myDatabase';
    end;

    

Open the Connection: Once the connection properties are set, you can open the connection using the Open method.

    begin
    UniConnection.Open;
    end;
	

Use the Connection: With the connection open, you can now use it to execute SQL commands, work with datasets, and perform other database operations.

Close the Connection: When you’re done with the database operations, close the connection using the Close method.

    begin
    UniConnection.Close;
    end;
    

Destroy the Connection: Finally, when the connection is no longer needed, destroy it to free up resources.

    begin
    UniConnection.Free;
    end;
	

Remember, managing database connections effectively is crucial for the performance and reliability of your application. Always close connections when they’re no longer needed, and handle any connection errors appropriately to ensure your application remains robust and responsive.

Working with UniDAC Dataset Classes

Working with datasets is a fundamental part of database programming. UniDAC provides a set of dataset classes that make it easy to retrieve, navigate, and manipulate data. In this section, we’ll cover how to edit dataset content, use UniDAC to edit dataset data, and post changes to a database.

Editing Dataset Content

Retrieve the Dataset: The first step in editing dataset content is to retrieve the dataset. You can do this by executing a SQL SELECT statement using the TUniQuery component.

    var
    UniQuery: TUniQuery;
    begin
    UniQuery := TUniQuery.Create(nil);
    UniQuery.Connection := UniConnection;
    UniQuery.SQL.Text := 'SELECT * FROM myTable';
    UniQuery.Open;
    end;
	

Navigate the Dataset: Once you have the dataset, you can navigate it using the First, Next, Previous, and Last methods. For example, to move to the next record, you would use the Next method.

    begin
    UniQuery.Next;
    End;
    

Using UniDAC to Edit Dataset Data

Start the Edit: To edit the data in a dataset, you first need to start the edit operation. You can do this using the Edit method.

    begin
    UniQuery.Edit;
    end;
	

Modify the Data: Once the edit operation has started, you can modify the data in the dataset. You can access the fields of the current record using the FieldByName method.

    begin
    UniQuery.FieldByName('myField').AsString := 'New Value';
    end;
	

Posting Changes to a Database

Post the Changes: After you’ve made the necessary changes to the dataset, you need to post the changes back to the database. You can do this using the Post method.

    begin
    UniQuery.Post;
    end;
    

Check for Errors: When posting changes to the database, it’s important to check for any errors that might occur. You can do this using a try/except block.

    begin
    try
    UniQuery.Post;
    except
    on E: EUniError do
    ShowMessage('An error occurred: ' + E.Message);
    end;
    end;
	

Close the Dataset: Once you’re done with the dataset, you should close it to free up resources.

    begin
    UniQuery.Close;
    end;
    

By understanding and effectively using UniDAC’s dataset classes, you can easily retrieve, navigate, and manipulate data in your database applications. In the following sections, we’ll delve deeper into other aspects of UniDAC, such as working with database metadata and preparing a UniDAC application for runtime.

Performance Tuning Techniques in UniDAC

Performance tuning is a critical aspect of database application development. It involves optimizing the speed and efficiency of database operations, which is crucial for applications that handle large amounts of data or have many concurrent users. UniDAC provides several features and techniques that can be used to enhance the performance of your database applications.

Direct Mode

Direct Mode is a feature of UniDAC that allows your application to work with a database directly without involving a database client library. This significantly simplifies the deployment and configuration of your applications and can also improve performance by reducing the overhead associated with client libraries.

To enable Direct Mode, set the Direct property of your TUniConnection component to True.

    begin
    UniConnection.Direct := True;
    end;
    

Mobile Development

UniDAC provides full support for mobile development, allowing your mobile applications to work with multiple databases as easily as desktop applications do. This can significantly improve the performance of your mobile applications by enabling them to directly access and manipulate database data without the need for a separate server-side API.

Server-Independent SQL

UniDAC provides a powerful macros engine that supports server-independent SQL. This allows you to write SQL queries that work with multiple databases, regardless of their specific SQL dialects. By using server-independent SQL, you can avoid the need to write and maintain separate queries for each database, which can significantly improve the maintainability and performance of your application.

Access Cloud Services

UniDAC provides the ability to work with data stored in various cloud services, such as Salesforce, QuickBooks, Zoho CRM, and others. This is achieved through the UniDAC ODBC provider in conjunction with Devart ODBC drivers for Clouds. By accessing cloud services directly from your application, you can improve performance by reducing the need for intermediate APIs or services.

Secure Connection

UniDAC allows you to establish a secure connection to your database server using SSL, SSH, or HTTP/HTTPS protocols. This not only enhances the security of your application but can also improve performance by reducing the risk of network-related issues or attacks that could slow down your application.

To establish a secure connection, you can use the SSLOptions property of your TUniConnection component.

    begin
    UniConnection.SSLOptions.Mode := sslmUnspecified;
    UniConnection.SSLOptions.Cert := 'myCert.pem';
    UniConnection.SSLOptions.Key := 'myKey.pem';
    UniConnection.SSLOptions.CA := 'myCA.pem';
    end;
    

By leveraging these features and techniques, you can significantly enhance the performance of your UniDAC-based applications. In the next section, we’ll discuss how to debug UniDAC applications and handle any errors that might occur.

In UI-design, first and foremost consider the nature of the brand and its emotional message. It is also important to keep in mind the peculiarities of visual perception: for example, to make the text contrast to the background, avoid too bright colors from which the eyes quickly tire. Take into account different features of monitors – their resolution and color rendering – so that the site was displayed correctly everywhere.

The result is a layout – a picture that looks exactly like the real interface.

The finished layout can be transferred to the frontend-developer, who will take it to the code. But if the site is a lot of complex or non-obvious animation, at the stage of design is useful to make a prototype – an animated layout. On him the developer will clearly see how the elements move. If there is no prototype, the frontrunner is guided by text notes or consults with the designer.

In large companies, UX- and UI-design are often handled by different specialists: one is responsible for user-friendliness, and the second – for beauty. But when it comes to small and medium-sized businesses, UX/UI designers who can do both are more in demand.

Beginners usually work with small firms: to get a job in a large company you need more qualifications and experience. That’s why it makes sense to simultaneously develop both UX and UI skills.

Knowledge of the basics of digital marketing. Businesses turn to creating websites and apps to make more profits with them. The designer must understand what motivates people to buy and be able to reach any audience.

Understanding UX research methods. This isn’t just important to conduct your own. Major analytics companies and marketing agencies also study user behavior and publish results – you need to understand and use them.

Communication skills and the ability to quickly immerse yourself in the product. Customers will come from different spheres: you may need to design a marketplace, an internet banking application, or an online cinema. Each business has its own specifics and audience, and you need to be able to listen to the client and ask the right questions.

Proficiency in vector graphic editors. The most popular program for interface design is Figma: you can use it to make window frames, draw icons and buttons, add simple animation. An alternative program is Sketch, though it is used less now.

Know the basics of typography. Fonts – an important part of the interface. The designer must choose them correctly – so that all the text is easy to read.

Skills in working with the grids. To make the interface uniform, all the content is placed on the grid. Small elements are usually aligned on the cells, reminiscent of millimeter paper (a pixel grid). And the main blocks are aligned by columns (this is a column grid). The most popular grid is a 12-column grid.

Understanding Coloristics. Choosing good colors for an interface is also a challenge. Colors can be used to accentuate the main thing and convey a particular mood.

The ability to make adaptive versions. Now it is extremely rare to find non-adaptive sites – they usually make versions for the desktop, tablets and mobile devices. And even if we are talking about mobile applications, smartphone screens are also different – and this must be taken into account. Nowadays, there are two ways to adapt the interface to the device – adaptive versions and responsive.

The ability to work with content. To create an interface you have to select photos, illustrations, icons at stock sites, change them slightly and repaint them. You can look for photos on Unsplash and Pexels, illustrations and icons on Freepik, Fraction and Icons8. You can also look for plugins for Figma with ready-made pictures. By installing them you can add free graphics, icons, diagrams and illustrations without leaving the program.

Inspectability. You have to look closely at the sites of major companies, spotting good compositional techniques, typography, colors. And some brands make their design systems publicly available – a set of elements and layout rules with explanations. These are almost textbooks: they show and tell how the interface was made.

Large companies have UX-laboratories where they conduct research: from simple interviews with users and A/B-tests to iTracking. Smaller firms don’t have the resources for this – then designers are guided by generally accepted rules and trends. This is not a problem: most users are experienced, they are used to existing sites, their expectations and behavior are quite predictable.

Often the most convenient interface is one that is similar to hundreds of others, because then people will have no problem finding the right buttons and blocks. There are patterns by which users browse interfaces. One popular pattern, for example, is the F-pattern.

In addition to patterns UX-designers think about the path of the user – from getting to the site to the target action (when the visitor placed an order or clicked on a link). Take into account different user scenarios. Some people, say, tend to make quick purchases, while others will flip through a catalog or get distracted by secondary sections. This all depends on the brand’s area of activity and the specifics of the audience.

The result of working on UX is a Wireframe. This is a schematic representation of the interface. It shows the main blocks, their size, location, and relationship to each other with the help of gray rectangles.
