1. What is Human Computer Interaction?
Human Computer Interaction is the field of study of mutual communication between the users and the computer. This is the field of interaction is equipped by using the user interface which includes the software as well as the hardware. All the software which are being made are enabled with users interface design and their implementation. It is an interdisciplinary field in which computer scientist, engineers, psychologist, social scientist and design professional play important roles. The knowledge gained from this study is used to create information system and work environments which help to make people more productive and more satisfied with their work.
2. What is brainstorming relating to Human Computer Interaction?
The brainstorming relating to human computer interaction is a group of method that is used for generating ideas. This process is often used to help find a solution to a problem. Brainstorming should not be confused with focus groups, where the function is to gather data on how users feel about a certain product or idea. It is useful in interaction design or usability engineering, as it can foster creative ideas. Due to the informal nature of brainstorming, team members are more likely to make suggestions without worrying about how these will be judged. It is important that suggestions are only analyzed for feasibility once collected. The aim of brainstorming is to collect numerous ideas.
3. What is Contextual Inquiry?
Contextual inquiry is seen by many as one route to human-centered HCI systems. It can reveal what cognitive work means to the people who are doing it, where they are doing it and while they are doing it. If designers tailor the system to how users themselves see their work and their world, then this has to bring designers closer to creating human-centered systems.
4. What is Making sense data?
Making sense data it is a practical, step-by-step approach to making sense out of data. Making Sense of Data educates readers on the steps and issues that need to be considered in order to successfully complete a data analysis or data mining project. It's provides clear explanations that guide the reader to make timely and accurate decisions from data in almost every field of study.
5. What is dynamic prototype in Human Interaction?
Prototyping is another type of software engineering models that can have a complete range of functionalities of the projected system. In HCI, prototyping is a trial and partial design that helps users in testing design ideas without executing a complete system. Example of a prototype can be Sketches. Sketches of interactive design can later be produced into graphical interface.
6. Discuss the technology and change?
The technology should be invisible hidden from sight. To develop information appliances that fits people needs and lives. To do this companies they develop products.
7. What is Human Computer Interaction?
Human Computer Interaction is the study of interaction between people (users) and computer. Human Computer Interaction is concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.
8. Discuss the concepts of interaction design?
Interaction Design is the design of interactive products and services in which a designer's focus goes beyond the item in development to include the way users will interact with it. Thus, close scrutiny of users' needs, limitations and contexts, etc. empowers designers to customize output to suit precise demands.
Usability is a measure of how well a specific user in a specific context can use a product/design to achieve a defined goal effectively, efficiently and satisfactorily.
Functionality refers to whether a design works and helps the users meet their goals and needs. From products such as chairs or tables to designs such as books or web interfaces, functionality varies but is everywhere. When a design is highly functional, it does what it's expected to do and does it well.
Visual design aims to improve a design's/product's aesthetic appeal and usability with suitable images, typography, space, layout and color.
User interface (UI) design is the process designers use to build interfaces in software or computerized devices, focusing on looks or style.
Information architecture is an incredibly important part of UX. It’s the creation of a structure for your site; organizing the information in a way that helps users understand where they are as well as what they need to do (or where they need to go) to complete their task.
Typographychoosing fonts and thinking about how text is displayed may not seem like one of the more vital parts of crafting a positive user experience.
9. Differentiate the Computer and Human-Computer Interaction?
Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery. Human-Computer interaction is all about designing computer systems that support people so that they can carry out their activities productivity and safely.
10. Discuss Data Gathering and Requirements Analysis with focus in HCI aspects?
Data collection tools refer to the devices/ instruments used to collect data such as a paper questioners or computer-assisted interviews system. Case Studies, Checklist, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data. Data gathering sessions should have clear goals. An informed consent may be needed. There are five key issues of data gathering are goals, choosing participants, triangulations, participant relationship and pilot. Data may be recorded using handwritten notes, audio or video recording, a camera, or any combination of these.
11. What are Interfaces Design and Prototyping?
Interface design provides ways for the programming team to receive input and make changes early in the design process that will save time and money for a company in addition to making an overall better product. Interfaces design has a common formats such as:
Graphical user interfaces (GUIs)- users interact with visual representations on digital control panels. A computer’s desktop is a GUI.
Voice-controlled interfaces (VUIs)- users interact with these through their voices. Most smart assistants—e.g., Siri on iPhone and Alexa on Amazon devices—are VUIs.
Gesture-based interfaces- users engage with 3D design spaces through bodily motions: e.g., in virtual reality (VR) games.
Prototyping is an experimental process where design teams implement ideas into tangible forms from paper to digital. In addition, there are four types of prototyping the following are:
1. RAPID PROTOTYPING is the most commonly used and plus. Its name refers to the ease and speed with which a prototype can be modified to try different ideas with the user audience and incorporate their feedback.
2. EVOLUTIONARY PROTOTYPING
An evolutionary prototype differs from the traditional notion of a software prototype; an evolutionary prototype is a functional piece of software, not just a simulation. Evolutionary prototyping starts with a product that meets only the system requirements that are understood.
3. INCREMENTAL PROTOTYPING is useful for enterprise software that has many modules and components which may be loosely related to one another. In incremental prototyping, separate small prototypes are built in parallel. The individual prototypes are evaluated and refined separately, and then merged into a comprehensive whole, which can then be evaluated for consistency in look, feel, behavior, and terminology.
4. EXTREME PROTOTYPING is more common for web application development. Web applications are composed of:
Presentation layer
Displayed in the user’s browser
Services layer
Communications services
Business logic
Authentication and authorization
Other back-end services
