The document provides an overview of Human-Computer Interaction (HCI), defining it as the study of the design, evaluation, and implementation of interactive computer systems for human use. It emphasizes the importance of making computers user-friendly and outlines the goals of HCI, which include improving safety, utility, effectiveness, efficiency, usability, and appeal. Additionally, the document discusses various aspects involved in HCI, including human psychology, computer hardware and software, and provides examples of good and poor design.
Introduction to Human Computer Interaction
- 1. Introduction to Human Computer Interaction Prof. Vishal Chaudhary Assistant Professor Department of Information Technology Hope Foundation’s International Institute of Information Technology, I²IT www.isquareit.edu.in
- 2. 0BHuman Computer Interaction: An Overview What is Human Computer Interaction (HCI)? Importance of HCI Good and Poor Design Examples What and Who are involved in HCI design?
- 3. What is HCI? The study of bridge between them, which includes Observation of interactions between people & computers, e.g., Find examination papers via our library Web Analysis of the involved interactions, e.g., Are all the steps involved are necessary? Human consequences after interacting with computers, e.g., Can the user perform his task? Does he enjoy working with the computer?
- 4. What is HCI? • concerned with the design, evaluation & implementation of interactive computer systems for human use & with the study of major phenomena surrounding them” (1992) • Dix: HCI is study of people, computer technology and these these influence each determine how we can make more usable by people” (1998) • Carroll: HCI is the study and practice of usability. It is about understanding and creating software and other technology that people will want to use, will be able to use, and will find effective when used.” (2002)
- 5. Why HCI? Now, computers are cheap and used by non-technical people (different backgrounds, needs, knowledge, skills) Computer and software manufacturers have noticed the importance of making computers “user-friendly”: easy to use, save people time, etc. How to achieve “user-friendliness” in computer design?
- 6. HCI Scope • Use & Context: Find application areas for computers • Human : Study psychological & physiological aspects e.g., study how a user learns to use a new product, study human typing speed • Computer: Hardware & software offered e.g., input & output devices, speed, interaction styles, computer graphics • Development: Design, implementation & evaluation
- 7. HCI Goals HCI develop or improve Safety Utility Effectiveness Efficiency Usability Appeal
- 8. Good and Poor Design Examples Inside a lift control Any problems?
- 9. Good and Poor Design Examples This is a lamp switch There are 3 modes: “I”, “O” and “II” correspond to Low, Off and High, respective Is it a good design? Why?
- 10. Good and Poor Design Examples This is an interface of a dialog box Is it a good design?
