• Visibility
• Errors
• Habits and agreements

Everyone can experience the feeling of awkwardness when they can't figure out simple actions, such as opening a door, finding a light switch, or turning on a stove. Donald Norman, former vice president of Apple and one of the leading designers of our time, argues that user errors are often caused not by their incompetence, but by design flaws. High-quality design should be intuitive and user-friendly to avoid situations where users encounter difficulties in everyday life. An effective interface plays a key role in ensuring a positive experience when interacting with products and services.

In 1988, Donald Norman published The Design of Everyday Things, which has become a cult work in the field of design. This book contains numerous examples of poor design solutions, as well as practical recommendations for avoiding common mistakes. Norman explores how design influences user interactions with products and emphasizes the importance of usability and intuitiveness in creating successful objects. His work remains relevant and continues to inspire designers around the world, emphasizing the need to consider user needs when developing new solutions.

In this article, we highlight key principles from The Design of Everyday Things that should be at the forefront of every designer's mind. These principles will help create more intuitive and user-friendly products. It is important to consider that successful design not only attracts attention but also facilitates interaction. By applying these ideas, designers can significantly improve the user experience, which in turn leads to increased customer satisfaction and loyalty. Follow these basic principles to create functional and aesthetically pleasing solutions in your design.

Visibility

For users to feel confident in a product, it is important that they clearly understand its purpose, possible states, and the functionality of its controls. Norman emphasizes the need to adhere to this principle, even if it requires compromising aesthetics. Understanding these aspects promotes more effective interaction with the product and improves the overall user experience. Norman is the originator of the popular "Norman's Doors" meme, which illustrates a situation where doors fail to open on the first try. Many of us have experienced this humorous moment when, trying to enter, we first pull the door toward us, then away from us. This evokes laughter and confusion. A photo posted by a Reddit user, which captures all the intricacies of this situation, illustrates this door. The "Norman's Doors" meme has become a symbol of everyday mishaps and sometimes funny moments in our lives.

The vertical handles look more traditional for pulling, but a closer look at the hinge mounts makes it clear that the door is meant to be pushed. This common misconception often leads to mistakes when opening doors. A proper understanding of how door handles work will help avoid misunderstandings and make using doors more convenient. Many doors feature instructions such as "pull," "push," "slide," "lift," "ring the doorbell," "insert card," "enter password," "smile," "spin," "bow," "dance," or even "ask to open." If a simple interior element like a door requires signs with instructions on how to open it—push, pull, or slide—this indicates poor and ineffective design. Proper design should be intuitive, allowing users to easily understand how to operate the door without having to read the instructions. Effective design promotes usability and safety, reducing the risk of miscommunication and enhancing the overall functionality of a space.

His ideas have had a significant influence on the development of UX design, as well as approaches to creating user interfaces. Donald Norman continues to share his knowledge and experience through lectures and articles, contributing to the improvement of design quality in various fields.

A mistake in the design of kitchen stoves is the incorrect placement of the controls. They are usually located in a single line, while the burners are arranged in a square. This can lead to inconvenience when using the stove, as it's difficult for the user to quickly and intuitively adjust the heating temperature. The optimal solution is to position the controls conveniently close to the burners, ensuring comfortable use and increasing cooking safety. Proper stove design is the key to efficient and safe cooking.

To solve this problem in the most economical way, it is enough to slightly raise the second and third regulators. This will allow the control panel to resemble the arrangement of the burners. This approach does not require significant costs and effectively optimizes the use of space.

Effective feedback should be provided immediately, visual, and ongoing. This allows users to confidently perceive that the system is functioning correctly. Feedback can be optimally implemented using progress bars, loading indicators, sound signals, and notifications. Such elements significantly enhance the user experience, making interaction with an app or website more informative and convenient.

Feedback issues in elevators can manifest themselves in the "sluggish" behavior of older models. Often, when a user presses the elevator call button, they receive no response. This can lead to people repeatedly pressing the button or even deciding to take the stairs, resulting in the elevator leaving empty. An effective solution to this problem can be to install an indicator that lights up after the button is pressed. This simple improvement lets the user know that the system is functioning properly and the elevator will arrive soon. Improving feedback in elevators will significantly increase user comfort and satisfaction.

The sound of a car engine serves as an important indicator for pedestrians. When a car approaches from behind, the characteristic engine noise allows people to react in time. Unlike traditional cars, electric vehicles operate almost silently, with only the sound of tires, wind, and high-frequency electronics being audible. This creates a potential hazard for pedestrians, as silent electric vehicles are difficult to spot from behind. It's important to consider these aspects when designing safe urban spaces and developing traffic regulations to improve the safety of all participants.

In order to improve the safety of electric vehicles, a new standard was introduced in the United States. Since September 2019, all electric vehicles are required to have an audible signal. This sound must imitate the engine sound of traditional cars, allowing pedestrians and other road users to always clearly understand the approach of a vehicle. This standard is aimed at preventing accidents and protecting people, especially in urban areas, where electric vehicles may be less noticeable at low speeds.

Feedback can be irritating if it becomes too intrusive and is provided in excess. It is important to find a balance between the amount of information received and its usefulness so that it truly helps improve processes and interactions. Feedback should be constructive and appropriate to the situation so as not to evoke negative emotions.

My dishwasher beeps at 3 a.m. to notify me when the cycle is complete. I run it at night to minimize noise and reduce energy costs. Despite this, the nighttime notification can be quite annoying.

When we are faced with an excessive number of messages, it can lead us to ignore them or turn off notifications. As a result, it is important to remember that we may miss truly significant messages. Feedback plays a vital role in our interactions, but too much of it can distract from more relevant and important communications. Optimizing feedback is necessary to ensure that it does not interfere with the perception of truly important information.

Donald Norman is a renowned American designer, author, and cognitive scientist. He is one of the founders of usability and interaction design. Norman actively explores how users interact with technology and how these experiences can be improved. His books, such as The Design of Everyday Things, have become classics in the design field, offering valuable insights on how to make products more intuitive. In his work, Norman emphasizes the importance of understanding users' needs and creating designs that take their behavior and perceptions into account. His contributions to usability and interface design are of great importance to today's developers and designers.

Errors

A user who encounters a problem should immediately recognize their error and be able to quickly correct it. Norman argues that if the user is left alone with difficulties, this indicates insufficient work by the designer on the product. Creating an intuitive interface that guides the user and helps them avoid errors is a key aspect of successful design. Effective solutions should provide support and make it easy to correct errors, which increases overall user satisfaction and improves interaction with the product.

Inserting AA batteries can be tricky, especially when it comes to the Xbox One controller. While the battery slots look identical, it's important to note that the batteries are installed differently. While there are icons on the contacts indicating polarity, this can be confusing. If you notice your controller isn't working, it's likely due to improper battery installation rather than a faulty compartment. Please pay attention to the correct direction when inserting the batteries to ensure proper operation of the device.

Creating a battery that cannot be inserted incorrectly presents an interesting engineering challenge. One solution is to use physical stops that allow the battery to be inserted into the socket only in one specific orientation. This will ensure a secure connection and prevent installation errors. Another approach is to design the battery and electrical contacts so that the battery's orientation does not affect its functioning. This method will simplify use and improve safety by eliminating the possibility of incorrect installation. The development of such technologies can significantly improve the user experience and minimize the risk of breakdowns.

Habits and Conventions

People often have difficulty adapting to changes in established systems. Disruption of habitual conventions necessitates the acquisition of new skills and approaches. In this case, the benefits of the new system remain obscured, and attention is focused only on the changes themselves. Adapting to new changes takes time and effort, which often leads to resistance and negative reactions.

The English system of measurement, based on inches and feet, is a prime example of the difficulty of changing people's habits. Although much of the world has already adapted to the metric system, which uses centimeters and meters, the United States continues to use the English system. This demonstrates the difficulty of changing ingrained traditions and habits, making the transition to more universal and logical units of measurement challenging.

Change can cause significant anxiety in people, especially when it comes to memorizing the new system and acquiring new tools or measuring equipment. These costs are often perceived as excessive. However, in reality, the retraining process is not as difficult as many people think, and the tools are quite affordable. The metric system is already widely used, even in the United States, making adaptation to new conditions easier. Understanding and using the metric system can be an advantage, contributing to greater efficiency and accuracy in a variety of fields.

Donald Norman is a renowned designer, cognitive scientist, and author who has made significant contributions to the fields of design and usability. His work focuses on how people interact with technology and how this experience can be improved. Norman is a proponent of an approach that considers user needs and behavior when creating products. He is also known for his books, such as The Design of Everyday Things, where he analyzes how design can influence the everyday use of objects and technologies. During his career, Norman has held positions at various universities and companies, including Apple, where he worked on improving the user interface. His ideas continue to inspire designers and developers around the world, making technology more accessible and user-friendly.

The interface of a standard elevator is a clear example of intuitive design. Users always select a floor directly from the cabin, and this practice remains unchanged in everyday life. This arrangement ensures the elevator is simple and easy to use, making it accessible to everyone. Thus, the elevator interface serves as a model for other user interfaces, emphasizing the importance of clarity and consistency in design.

In multi-story buildings, elevators with destination control are used, which optimize the movement of passengers. This system brings together people heading to the same floor, allowing them to rise together. This approach reduces the load on elevators and improves their efficiency. However, there is a significant problem: the control panel is located not in the elevator car, but in the corridor, which can cause inconvenience for users.

A person won't immediately understand how this elevator functions. They won't be interested in efficiency and convenience—without proper elevator agreements, everything else becomes meaningless.

QWERTY keyboards are the standard in the world of computing devices and are used everywhere. Most users don't even consider the possibility of changing to an alternative layout. You likely work with this layout every day. QWERTY has become a familiar layout for millions of people, providing convenience and speed in typing. It's important to note that despite QWERTY's prevalence, other layouts exist that can offer various benefits, such as increased typing speed or convenience for users with special needs. However, QWERTY remains the most popular and widely used layout in the world.

Alternatives to the QWERTY layout include Dvorak, which offers faster typing speeds. However, switching to a new layout is not a common practice. Users will need to retrain, and manufacturers will need to adapt keyboard production to the new layout. Given that the performance gain is insignificant, such an investment is not justified for most users.

It is important to strive for consistency in approaches and methods of work. If a new way of doing a task is only slightly superior to the old one, it makes sense to continue using proven methods. However, if change is necessary, everyone involved in the process must adapt to the innovations. Mixing different systems can lead to confusion and decreased efficiency. If a new method significantly improves results compared to the old one, the benefits of implementing the change outweigh the potential difficulties associated with their implementation.

New ideas and approaches are not always negative. Attachment to established traditions can limit our development and progress. Embracing innovation opens up opportunities for improvement and achieving better results.
