Affordances are the properties of a thing that communicate to us how it can be used. When we perceive properties, we form expectations about what will happen when we interact with the object. Sometimes affordances are spoken of as things, rather than properties.

It refers to the properties of an object or environment that permit social actions. Social affordance is most often used in the context of a social technology such as Wiki, Chat and Facebook applications and refers to sociotechnical affordances.

Communicative affordances are defined as an interaction between subjective perceptions of utility and objective qualities of the technology that alter communicative practices. Perceptions of the utility of particular technologies are affected by experimentation, social norms, and learned understandings.

Human-Computer Interaction (HCI) has four main components: the user, task, tools / interface, the context. HCI studies requires the evaluation of obtained observations while the user performs certain tasks and habits of the user together. These data are used in the development process of interactive systems.

Principles of design: Use both knowledge in the world and knowledge in the head. 2. Simplify the structure of tasks.

Knowledge in the head is memory. Knowledge in the world is everything else — external information. Back to knowledge in the head, there are three types of memory: memory for arbitrary things, for meaningful relationships, and for explanation. Memory for arbitrary things is straight memorization.

As its name implies, HCI consists of three parts: the user, the computer itself, and the ways they work together.

Human-Computer Interaction (HCI) is a multidisciplinary field which combines the theories and practices from a number of fields including computer science, cognitive and behavioral psychology, anthropology, sociology, ergonomics, industrial design, and more.

(Science: chemical) hydrochloric acid. Solutions of hydrogen chloride gas in water. It is a highly corrosive, strong mineral acid commonly used as a laboratory reagent. It is present endogenously as the acid component of gastric juice (hydrochloric acid, gastric see gastric acid). chemical name: hydrochloric acid.

The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

In the human body, HCl is produced by the parietal cells of the stomach lining. The parietal cell cytoplasm combines with water and carbon dioxide to produce carbonic acid.

HCI design is considered as a problem solving process that has components like planned usage, target area, resources, cost, and viability. It decides on the requirement of product similarities to balance trade-offs. The following points are the four basic activities of interaction design −

The interaction design (IxD) process is what designers use to create solutions centered on users’ needs, aims and behavior when interacting with products.

Shneiderman’s “Eight Golden Rules of Interface Design” are a guide to good interaction design.

• 1 Strive for consistency.
• 2 Enable frequent users to use shortcuts.
• 3 Offer informative feedback.
• 4 Design dialog to yield closure.
• 5 Offer simple error handling.
• 6 Permit easy reversal of actions.

In other words, you conducted the four fundamental activities that make up the interaction design process – establishing requirements, designing alternatives, prototyping designs, and evaluating prototypes.

THE DESIGN PROCESS CONSISTS OF 6 STEPS:

• Define the Problem. You can’t find a solution until you have a clear idea of what the problem is.
• Collect Information. Collect sketches, take photographs and gather data to start giving you inspiration.
• Brainstorm and Analyze Ideas.
• Develop Solutions.
• Gather Feedback.
• Improve.
