What is Human-Computer Interaction?
Human-computer interaction is the field that studies how people interact with computers and explores ways to design computers.It supports and enhances human activity.
Types of Human-Computer Interaction
Human-Computer Interaction is a broad field that includes many different subfields. However, there are three basic areas he has that have a great impact on human-computer interaction.
Human-computer interaction subfield
- Human factors and ergonomics.
- interaction design.
- Accessibility and assistive technology.
1. Human factors and ergonomics
Human factors research seeks to understand how people’s characteristics affect their performance as they interact with products and systems. Examples of human factors include perception, cognition, and physical ability.
Ergonomics is the application of the human factor to product design. Ergonomics directly affect work productivity and safety. Ergonomic products are designed for human needs, making them more comfortable to use and making work processes safer and more efficient.
2. Interaction design
Interaction design focuses on designing interactive products.this‘A user-centered design approach that involves understanding the needs, goals, and behaviors of the people who use your product. The aim is to create an easy-to-use and efficient product.
3. Accessibility and assistive technology
Good design is accessible design. Initially, accessibility was part of interaction design, but as digital products became more complex, accessibility inevitably became a separate discipline.
Accessibility is the study of how technology can be used by different groups of users, including people with disabilities. The team achieves this goal by making the user interface compliant. Web Content Accessibility Guidelines (WCAG) standard. These recommendations include using appropriate font sizes and color contrast to make text and functional elements readable, using safe visual effects to prevent motion sickness in your design, and using screen readers and other This includes supporting assistive technologies to enable users with low vision to rely on assistive technologies. interact with the product.
How to design good human-computer interactions
Good human-computer interaction design follows a few basic principles.
Basic Principles of Human-Computer Interaction
- Conduct user research.
- Use familiar design patterns.
- Make interactions efficient and predictable.
- Create aesthetically pleasing designs.
- Define usability metrics to guide product development.
1. Conduct user research
First and foremost, you need to understand the needs, goals and behaviors of the people using your product.can be carried out User research User interviews, diary surveys, usability test, and other research methods. Product makers use insights gleaned from research to user persona, is the archetype of the ideal user. This user persona becomes a fundamental element of the product design process. All product design decisions are evaluated according to the user persona.
2. Use familiar design patterns
When people start using a new product, they have certain expectations of how it will perform. Most of the time, people feel more comfortable when: User interface It looks like an interface and behaves the same.‘I have used it before. Affinity helps users learn how to use the product faster and minimizes the number of mistakes users may make when working with the product.
So if you’re designing for a specific platform, the first thing you should do is follow the platform’s guidelines and Research competitors in your product nicheThat way you can design a product that matches the expectations of your target users. For example, let’s say you’re designing an iOS mobile app.then you need to check apple‘s Human Interface Guidelines research competitors‘ Apps (that is, apps in the same category in the App Store).
3. Make interactions efficient and predictable
Why do people want to use your product? They have specific goals they want to achieve and they expect your product to help them achieve that. So you need to know what tasks your users want your product to perform.
You should identify your important tasks and optimize your interface accordingly. This means that the most important and frequently used functional controls should be on the home screen or easily found.Users don’t have to click/tap multiple times to access your product‘Main features of.Rely on Proven Experience 3 click rule It states that users of your product should be able to find information in no more than three mouse clicks.
Human-computer interaction is the interaction between a user and a computer. As users interact with their machines, it’s natural to expect feedback. Feedback serves as confirmation of the user’s interaction. Notifies the user that the system has received the request and is processing it. Depending on the nature of the product and interaction, feedback may be visual (i.e. buttons change color when a person clicks them), tactile (i.e. tactile feedback from a touch screen), or auditory (i.e. the system knows what is playing), or a combination of all of these.
4. Create beautiful designs
Aesthetics refers to the visual appearance of a product. While this is not a specific area of human-computer interaction, it can have a significant impact on how users perceive technology. An aesthetically pleasing product can impress users, increase their engagement, and improve product perception. This phenomenon is aesthetic usability effect.
Veteran product designers often see aesthetics as one of the key factors in creating a positive user experience. They aim to create visually appealing interfaces. That is, a design with a visual hierarchy of elements, good font combinations, and color choices. Because such an interface is easier on the eyes.
5. Define Usability Metrics to Guide Product Development
How do you know if your design is good for your users? To measure the performance and effectiveness of your design, you need to use metrics. The exact set of metrics will vary depending on the nature of the product, but generally include task time (how long it takes a user to complete a particular task), error rate (number of errors a user encounters along the way) must be tracked.When Task level satisfaction (How well the product meets the task at hand). Once you have defined your set of metrics, you should use the same set in each usability testing session. Doing so helps you see how your product design evolves in a dynamic environment.
Continuously improve your design
Human-computer interaction is an area that forces designers to think about creating products that provide a great user experience. It’s nearly impossible to release a perfect product on the first try. Most of the time, you need to continually improve your design until you reach a point where you can say your product offers a great user experience. But even after that, you shouldn’t stop working on your design. User needs and preferences change over time, so adapting designs to the changing product design environment is essential.
