Interaction design works focus on Schick's Law and Jacob's Law. On the way to apply for the field of interaction design, many students can easily show beautiful user interface (UI) design works. However, these works are often unattractive in the eyes of interviewers. The key reason behind this is that they failed to make full use of important guiding principles such as Schick's Law and Jacob's Law to guide their design practice. Today, we will discuss in depth the application of these two principles in the interaction design works collection to help everyone improve the quality of works and attract the attention of interviewers.

In the field of interaction design, the quality of user experience often determines the success or failure of products. As the two core principles of human-computer interaction, Schick's Law and Jacob's Law provide us with a unique perspective to optimize the user experience.

How to follow these laws while maintaining product innovation is a problem that every interaction designer needs to think deeply about.

　　 Schick's law

Hick's Law, or Hick Hyman Law, is a basic principle in the field of human-computer interaction, involving the time of human choice and decision-making. This law was first proposed by William Edmund Hick in 1952 to describe the relationship between the time needed to make decisions and the number of options available when facing multiple choices.

The core idea of Schick's Law is that the more choices (n) a person faces, the longer the time (T) it takes to make a decision. This is often because people need to evaluate the likelihood and outcome of each option. Specifically, Schick's law can be expressed by the following mathematical formula: T=a+b*log2(n)

In the interface design of interactive works collection, too many options will cause users to feel confused and at a loss. In order to reduce the decision-making cost of users, we should streamline the options and only retain the core functions that are really valuable to users. By removing redundant and infrequent functions, we can help users find what they need faster, thus improving operational efficiency.

When multiple options cannot be avoided, we can reduce the cognitive burden of users through reasonable classification and organization. Classify relevant options to form a clear hierarchical structure, which helps users quickly locate the information they need. At the same time, reasonable information architecture and navigation design are also the key to improving user experience.

In interaction design, we can also guide users to make more reasonable choices by providing default values, recommended options or personalized suggestions. These guiding measures can help users quickly find options that meet their needs and preferences, and further improve the user experience. At the same time, the application of intelligent recommendation algorithm can also bring more personalized experience to users.

　　 Jacob's law

Jacob's Law, also known as "Jacob's User Experience Law" or "Jacob Nielsen's Law", was proposed by the famous usability expert Jacob Nielsen. This law mainly describes the design consistency and familiarity that users expect when using new products or services.

Specifically, Jacob's Law points out that when users use new products or services, they will tend to use products that have similar design patterns and interaction methods with products or services they have used in the past. This is because people tend to understand and use new things based on their own experience, which can reduce learning costs and improve efficiency.

In order to design products that meet users' expectations, we need to have a deep understanding of their mental models and usage habits. Through user research, interviews and testing, we can gain insight into users' understanding and expectations of the product, so as to ensure that the design conforms to their mental model.

stay Creation of interaction design works Following industry practices and standards is an important way to achieve consistency. Using familiar design elements, interaction methods and operation processes can reduce user learning costs and improve product usability. At the same time, compliance with standards will also help improve the professionalism and credibility of products.

In addition to following industry conventions, we also need to ensure consistency between various parts of the product. This includes design style, color scheme, font selection, icon design and interaction mode. By maintaining internal consistency, we can create a harmonious and unified use environment for users and further improve the user experience. At the same time, it also helps to shape the brand image of the product and enhance the user's sense of identity.

　　 Innovation and user experience

In interaction design, innovation and user experience often restrict each other. In order to find the balance point, designers can adopt the progressive innovation strategy, gradually introduce new functions and design elements, and pay close attention to user feedback to continuously optimize the product. In addition, educating and guiding users to cultivate their new usage habits is also an important means to promote innovation.

In order to introduce innovative elements on the basis of maintaining the consistency of user experience, we can adopt the method of incremental innovation. This means that only a few new design elements or interaction methods are introduced in each iteration, so that users can gradually adapt to and accept these changes. By gradually introducing innovation, we can ensure that the user experience will not be affected, and at the same time, we can bring continuous freshness and value to users. At the same time, it also helps to reduce the risk and cost of products.

Interaction design is a process of continuous iteration and optimization. After the product is released, we need to pay close attention to user feedback and usage, and find and solve existing problems in a timely manner. By collecting user feedback, analyzing usage data and conducting user tests, we can continuously optimize product design and improve user experience. At the same time, this is also a process of continuous innovation. We can introduce new design elements and interaction methods in continuous optimization to meet the changing needs of users. In addition, keeping close communication with users is also the key to improving product quality and user experience.

　　 Today's summary

Schick's Law and Jacob's Law provide us with valuable guidelines for optimizing interaction design. It is the responsibility of every interaction designer to focus on the needs and challenges of user experience while pursuing innovation.

By deeply understanding and applying these laws and adopting appropriate strategies and methods to balance the relationship between innovation and user experience, we can create new and easy-to-use products and bring users a better digital experience.

In the future design practice, we should flexibly apply these two laws, combine user needs and scene characteristics, and create innovative and easy to use products. At the same time, we should also maintain our sensitivity to new technologies and concepts, and keep forging ahead on the road of exploration and innovation to bring users a more exciting and diverse digital world.
