Human-Computer Interaction (HCI) User Experience (UX) topic overview/definition
Human-Computer Interaction (HCI): Concept Definition
Human-Computer Interaction (HCI) is a field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. It encompasses multiple disciplines, such as computer science, cognitive science, and human-factors engineering. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design.
HCI emerged in the 1980s. It was the crucial instrument in popularizing the idea that the interaction between a computer and the user should resemble a human-to-human, open-ended dialogue. It initially focused on using knowledge in cognitive and computer sciences to improve the usability of computers (i.e., concentrating on how easy computers are to learn and use). However, since then—and thanks to the advent of technologies such as the Internet and the smartphone—it has steadily encompassed more fields (including information visualization, social computing, etc.). The relevance of HCI in the 21st century is particularly apparent in the breakthrough of new modes of interactivity, namely voice user interfaces (VUIs).
In many ways, HCI was the forerunner that would grow to become what we now call “User Experience (UX) Design.” Despite that, some differences persist between HCI and UX design. Practitioners of HCI tend to be more academically focused, and are involved in scientific research and developing empirical understandings of users. UX designers, on the other hand, tend to be industry-focused, and most UX designers are involved in building a product or service—for example, a smartphone app or a website. Regardless of this difference, the practical considerations for products that UX designers concern themselves with have direct links to the findings of HCI specialists about the mindsets of users. Due to this, there is little point in separating these realms to any great extent.
For your convenience, we’ve collected all UX literature that deals with Human-Computer Interaction (HCI). Here’s the full list:
Human Data Interaction (HDI): The New Information Frontier
After more than 40 years in the field, Human Computer Interaction (HCI) is already a well-established design discipline. Now, the pervasiveness of big data, new data collection and interaction techniques is giving rise to a new but related discipline: Human Data Interaction (HDI). This is likely to be a field with major new opportunities for des...
Design iteration brings powerful results. So, do it again designer!
The iterative design process is a simple concept. Once, through user research, you have identified a user need and have generated ideas to meet that need, you develop a prototype. Then you test the prototype to see whether it meets the need in the best possible way. Then you take what you learned from testing and amend the design. Following that...
Guidelines for Design for Appropriation
Appropriation occurs when a user takes a design and puts it to use in a way that wasn’t anticipated by the designer. This can have real benefits for a product; it enables the product to become more useful and can increase the product’s appeal to different audiences and increase its market life too. However, how do you design for things that you ...
A Very Useful Work of Fiction – Mental Models in Design
Mental models play an important role in Human-Computer Interaction (HCI) and interaction design. They relate to the way that a user perceives the world around them and are based in belief as opposed to being a factual concept. However, if you can understand your users mental models you can simulate these models within your designs to make them m...
