  1. CS814PE: HUMAN COMPUTER INTERACTION (Professional Elective - VI)
  2. Course Objectives • To gain an overview of Human-Computer Interaction (HCI), with an understanding of user interface design in general, and alternatives to traditional "keyboard and mouse" computing. • become familiar with the vocabulary associated with sensory and cognitive systems as relevant to task performance by humans. • be able to apply models from cognitive psychology to predicting user performance in various human- computer interaction tasks and recognize the limits of human performance as they apply to computer operation.
  3. Course Objectives • appreciate the importance of a design and evaluation methodology that begins with and maintains a focus on the user. • be familiar with a variety of both conventional and non- traditional user interface paradigms, the latter including virtual and augmented reality, mobile and wearable computing, and ubiquitous computing • understand the social implications of technology and their ethical responsibilities as engineers in the design of technological systems. • Finally, working in small groups on a product design from start to finish will provide you with invaluable team-work experience.
  4. Course Outcomes: • Ability to apply HCI and principles to interaction design. • Ability to design certain tools for blind or PH people.
  5. UNIT - I • Introduction: Importance of user Interface – definition, importance of good design. Benefits of good design. A brief history of Screen design. • The graphical user interface – popularity of graphics, the concept of direct manipulation, graphical system, Characteristics, Web user – Interface popularity, characteristics- Principles of user interface.
  6. What is HCI?
  7. • HCI stands for Human-Computer Interaction. • It is an interdisciplinary field that focuses on the design, evaluation, and implementation of interactive computing systems for human use. • The goal of HCI is to create intuitive and user-friendly interfaces • between humans and computers that allow people to interact with technology in a natural and efficient way. • This involves understanding human behavior, cognitive processes, and social interactions, as well as the capabilities and limitations of computers and other digital devices.
  8. • HCI is a critical component in the design and development of software applications, websites, mobile devices, and other interactive technologies. • It involves a range of methods and techniques for studying user behavior, such as usability testing, user surveys, and user-centered design. • The ultimate aim of HCI is to improve the user experience and make technology more accessible and effective for all users.
  9. What is User Interface?
  10. • A User Interface (UI) is the point of interaction between a user and a digital device such as a  Computer  mobile phone  or other electronic device. It includes: all the visual, audio, and tactile elements that users can see, hear, and touch when they interact with a device. as well as the overall layout and organization of information on the screen.
  11. List some of the Components of User Interface ?
  12. User Interface has two components • Input • Output Input is how a per communicates his/her needs or desires to the computer. Common input components are Keyboard, mouse, trackball, voice Output is how the computer conveys the results of its computations and requirements to the user.
  13. next class Why user Interface is important? General considerations for designing user interface. what is meant by good user interface? Benefits of good design.
  14. Why user Interface is important?
  15. • User interface is important to meet user expectations (accessability, visual aesthetic and ease of use) and support the effective functionality of user site. • A well executed user interface facilitates effective interaction between the user and the program. • An optimal mix of effective visuals and efficient responsiveness will improve site’s conversion rates. • It anticipates the needs of the user and then satisfies those needs.
  16. General considerations for designing user interface
  17. 3 general considerations for designing of user interface: • Whether the system uses custom built screens or browser based. • What devices will it be used on. • Which operating systems will it support.
  18. what is meant by good user interface? • Clear • Consistent • Simple • User-controlled • Direct and • Forgiving
  19. Benefits of good design • Training costs are lowered. • Employee / user satisfaction will improve. • Builds customer relationships. • Bounce rates will lower.
