HCI Design

Human-Computer Interaction Design is a multidisciplinary field that puts emphasis on the interaction between a computer and a human. It’s about ensuring the smooth interaction between a human and a computer system by ensuring that the computer systems are user-friendly and efficient. HCI designs have some key aspects, some of which are listed below:

• User-centric Design: The heart of HCI design is to make the computer system user-friendly, to do that it is recommended to design the computer in the most user-friendly way possible. This approach takes into account the need of the user and their preference throughout the entire design process.
• Prototype: Most of the time designers create a prototype of the final product and let the users try it beforehand and ask them to provide feedback so that they can make some improvements in the final product and the final product will have fewer problems.
• Accessibility: HCI designers also need to keep in mind the systems that can be accessible by everyone, even by the person who has some disabilities. So keeping that in mind and adhering to the rules, they designed the system in such a way so that everyone can use that.
• UI Design: The main thing that comes up when using any system is the User Interface (UI), and a simpler UI makes more people use the application. So the designers use various design software to come up with a simple yet effective UI that everyone can use.

There are three principles which are used by the designers for the user-centered approach:

• Data based evaluation
• Early Emphasis on User Needs and Objectives
• Design in an iterative manner.

Data-Based Evaluation

Data-based evaluation is a technique that depends upon user feedback and empirical data to assess the usefulness of a certain design prototype before making the final design. This process is solely done to ensure that the design meets all the expectations of the main user or the stakeholders.

Early Emphasis on User Needs and Objectives

Putting an early emphasis on the user needs and objectives makes the design more user-friendly as well as used to improve the design based on the user’s need, main aim, and context. It also helps to ensure that the final design is user-centric, fulfills the user’s needs and easy to use by the user. Usually the designers does this during the early stage of the design, so that they keep in mind about the user’s needs and aim throughout the entire design process.

Design in an Iterative Manner

Desiging in an Iterative manner means that the entire design process from start to end is not a linear process, In a linear process, the designer starts the design and throughout the entire process of the design they don’t listen to the user or any others and just delivers the final product as instructed to him at the start.

In an iterative approach, the designer creates a certain product (prototype), let the user test the product and then gathers the feedback from the user, using the feedback they make changes in the design and again let the user test it until and unless the user says that they liked the product and no other change is needed to do there.

Design Process is a systematic approach used by the designers to resolve complex issues or problems and deduce the solution. It is a structural method that helps designers to think, plan, and execute their ideas in real life to solve the complex problems given to them. In the rapidly changing world, design plays a key role in making any product or service to satisfy customers and meet their expectations. In this article, we will see some of the most important aspects of the Design Process and Task Analysis, and dig deep into the world of Design Methodologies, Task Analysis, Types of Task Analysis
