  • Hey Shamik, thanks for pointing out. I was just trying to illustrate the different roles involved. In fact the screenshots in the later slides are of different products. :) I should have mentioned it as just roles involved in going for designing for a better experience, rather than the iPod Experience. However there would definitely have been some amount of research done in the design of the product. If nothing, atleast a competitor analysis :) Thanks again.

  • Something that seemed a bit contradictory in the iPod example is that do you think that Apple actually used the services of user researchers and usability analysts . I feel Jobs was the guy who was the 'ultimate user' and all user-related decisions were his.. Correct me if I am mistaken :)

  • # How do you do? What sort of ways do you affect the world: poke it, manipulate it, sit on it? # How do you feel? What do you sense of the world and what are the sensory qualities that shape media? # How do you know? What are the ways that you learn and plan (or perhaps, how we want you to think)?
  • HCI Professionals as MEDIATORS. Their ability to be the bridge to help people in the team understand better.
  • Introduction To HCI

    1. 1. Introduction to HCI Kshitiz Anand
    2. 2. What is HCI? <ul><li>Human Computer Interaction </li></ul><ul><ul><li>Definition captures more of the interaction. Which is not just limited to the interface. </li></ul></ul><ul><li>Human Computer Interface </li></ul><ul><ul><li>Incorrect definition: Capturing only the final interface. </li></ul></ul><ul><li>One line definition: HCI is the study of interaction between people (users) and computers. </li></ul>
    3. 4. Where does it come from? HCI Cognitive Psychology Computer Science Fine Arts Design
    4. 5. <ul><li>Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them. </li></ul>How about this ? ACM Definition
    5. 6. Brief History of HCI <ul><li>Gained prominence in the early 1980s </li></ul><ul><li>Research at Stanford Research Labs and MIT </li></ul><ul><li>GUI research at Xerox PARC </li></ul><ul><li>Apple Macintosh </li></ul><ul><li>Windows 95 interface </li></ul><ul><li>Research at Universities and Industrial research laboratories at the corporate level in Xerox, IBM, AT&T, and others </li></ul><ul><li>Expansion from the desktop to environments to gestures </li></ul>
    6. 7. Waves of HCI
    7. 8. First Wave <ul><li>1980s </li></ul><ul><ul><li>Rigid guidelines </li></ul></ul><ul><ul><li>Focus on user and the user dimensions </li></ul></ul><ul><ul><li>Anthropometry </li></ul></ul><ul><ul><li>Human factors </li></ul></ul><ul><ul><li>Work related to the desktop </li></ul></ul><ul><ul><li>Machine centered notion </li></ul></ul><ul><ul><li>Usability testing and experimental psychology </li></ul></ul><ul><ul><li>Tasks based actions </li></ul></ul>
    8. 9. Second Wave <ul><li>1990s </li></ul><ul><ul><li>Context Based </li></ul></ul><ul><ul><li>Expansion of HCI research to workspaces </li></ul></ul><ul><ul><li>Context where interactions happened </li></ul></ul><ul><ul><li>Focus on the word ‘Humans’ from ‘Users’ </li></ul></ul><ul><ul><li>Emphasis on trying to design for workspace and people around it </li></ul></ul><ul><ul><li>Focus on newer Methods and Rational Thinking </li></ul></ul><ul><ul><li>Participatory Design becomes famous </li></ul></ul>
    9. 10. Third Wave <ul><li>2000s </li></ul><ul><ul><li>Expanding the reach of HCI to homes and larger environments </li></ul></ul><ul><ul><li>Users are now called actors and participants </li></ul></ul><ul><ul><li>Cultural differences takes prominence </li></ul></ul><ul><ul><li>Solidified Design Processes being followed </li></ul></ul><ul><ul><li>Non Rational Thinking adopted </li></ul></ul><ul><ul><li>Thinking out of the box supported at large </li></ul></ul><ul><ul><li>Research on non tangible factors like Emotions </li></ul></ul><ul><ul><li>Design inputs from multiple mediators </li></ul></ul><ul><ul><li>Wider range of application of technology </li></ul></ul>

    32. 33. The Experience!
    33. 34. Some Job roles in HCI that would have gone into the making of the iPod experience
    34. 35. User Experience Researcher <ul><li>Applies the different methods like ethnography, contextual inquiry, surveys etc of research to get information about the potential users and existing users. </li></ul>
    35. 36. <ul><li>Information architecture is concerned with the structure of content: how to best structure and label content so that users find the information they need. </li></ul>Information Architect
    36. 37. Communication / Visual Designer <ul><li>Communication design is about creating a visual language to communicate content. </li></ul><ul><li>The fonts, colors, and layout of Web sites and printed materials like this book provide examples of communication design. </li></ul>
    37. 38. Industrial Designer <ul><li>Industrial design is about form shaping objects in a way that communicates their use while also making them functional. Physical objects like mobile, chairs, tables, etc illustrate this. </li></ul>

    39. 40. Interaction Designer <ul><li>This is about how humans relate to each other. Looks into the interactions between humans-computer, computer-computer, computer-human and human-human in varying systems and contexts. Includes any area where technology is applicable. </li></ul>
    40. 41. Usability Engineer <ul><li>Usability engineering is about testing products to make sure they make sense to users based on a certain set of rules and heuristics. </li></ul>
