| Similarities | Differences | HCI | HCI (human-computer interaction) is the study of how people interact with computers and to what extent computers are or are not developed for successful interaction with human beings | An important HCI factor is that different users form different conceptions or mental models about their interactions and have different ways of learning and keeping knowledge and skills (different "cognitive styles" as in, for example, "left-brained" and "right-brained" people). In addition, cultural and national differences play a part. Another consideration in studying or designing HCI is that user interface technology changes rapidly, offering new interaction possibilities to which previous research findings may not apply. Finally, user preferences change as they gradually master new interfaces. | UX | User experience design (UXD or UED) is the process of enhancing user satisfaction by improving the usability, ease of use, and pleasure provided in the interaction between the user and the product.[1] User experience design encompasses traditional human–computer interaction (HCI) design, and extends it by addressing all aspects of a product or service as perceived by users. | As technology evolves, the goal of UX/HCI is to make it easier for people to use all kinds of digital technologies to accomplish their goals. This includes reducing the barriers to using these tools, whatever the physical ability of the user or the nature of the task; creating a positive user experience including visual and structural elements; ensuring the user can easily navigate the site/device and find what they are looking for; and creating content which is understandable and accessible to the user. | UI | The user interface, in the industrial design field of human–machine interaction, is the space where interactions between humans and machines occur. | The user interface (UI) is everything designed into an information device with which a human being may interact -- including display screen, keyboard, mouse, light pen, the appearance of a desktop, illuminated characters, help messages, and how an application program or a Web site invites interaction and responds to it. In early computers, there was very little user interface except for a few buttons at an operator's console. The user interface was largely in the form of punched card input and report output. | ID | In designing, human–computer interaction, and software development, interaction design, often abbreviated ID, is "about shaping digital things for people’s use",[1] alternately defined as "the practice of designing interactive digital products, environments, systems, and services | Interaction design is about shaping digital things for people’s use.The Goal of ID is to * Develop usable products * Usability means easy to learn, effective to use and provide an enjoyable experience * Involve users in the design process | UCD | 1. 2. 3. User-centered design (UCD) is a process (not restricted to interfaces or technologies) in which the needs, wants, and limitations of end users of a product, service or process are given extensive attention at each stage of the design process. | Human/User Centered Design is a design philosophy that puts the needs of the person using the system over the needs of the system. In other words, if there is a choice between making the user do something extra to achieve their goal or making the System do it for the user, then the choice would be to burden the system, not the user |

Comparison between Usable, Useful and Used:- Useful | Usable | Used | The more usable a tool is, the better it works and the more useful it is. So if we want to build truly excellent products, they must be usable, you can't really make a truly useful tool if it's not really usable. It's a change in thinking from requirements gathering and specification to understanding what the people who will be using the software want to achieve? What their goals are and how they go about achieving them? | Usability is the ease of use and learnability of a human-made object. The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with. Usability is how easy or difficult something is to use. Usability can be measured through a scientific process focused on evaluating user critical tasks and the ability. Usability includes how efficient something is, how easy it is to learn, and the ability of the item to satisfy the user. | Being used is the term mostly used for the object or the modules that were handy or useful one but after performing their particular jo or certain task They are no considered anymore or re-engineered. But only left for increasing the user experience when needed. |
