Transcript of "Hci"

  1. 1. Human-Computer Interaction By: B . Sudheer reddy & K . Sai kiran.
  2. 2. DigitalThink lessons <ul><li>Confusions related to course interface </li></ul><ul><li>Orientation phase </li></ul><ul><li>Buttons unexplained </li></ul><ul><li>User can easily be stuck on lower levels (discussion threads etc.) </li></ul>
  3. 3. Human-Computer Interaction <ul><li>Human </li></ul><ul><ul><li>the end-user </li></ul></ul><ul><ul><li>the others in the organization </li></ul></ul><ul><li>Computer </li></ul><ul><ul><li>hardware </li></ul></ul><ul><ul><li>software </li></ul></ul><ul><li>Interaction </li></ul><ul><ul><li>user “tells” the computer what (s)he wants </li></ul></ul><ul><ul><li>computer communicates results </li></ul></ul>
  4. 4. Practical implication of HCI <ul><li>Design, </li></ul><ul><li>Implementation and </li></ul><ul><li>Evaluation of user interfaces </li></ul>
  5. 5. Importance of HCI <ul><li>Productivity </li></ul><ul><ul><li>individual (e.g. installations, word processing) </li></ul></ul><ul><ul><li>organizational (changing job content, satisfaction, working environment, power and influence) </li></ul></ul><ul><li>Safety (e.g. nuclear plants, flight control) </li></ul>
  6. 6. A model of HCI People Technology Work Level 1 Level 2 Level 3 Social system Organisational goal
  7. 7. Disciplines, contributing to HCI <ul><li>Computer science </li></ul><ul><li>Cognitive psychology </li></ul><ul><li>Social & organizational psychology </li></ul><ul><li>Ergonomics </li></ul><ul><li>Artificial intelligence </li></ul><ul><li>Linguistics </li></ul><ul><li>Philosophy, sociology, anthropology </li></ul>
  8. 8. Factors in HCI Organisational: job design, roles, policies, Environmental: noise, heating, lighting, ventilation, Health: stress, headaches The user : motivation, satisfaction, experience Comfort : seating User interface : I/O devices, color scheme, icons, dialogue, help Task : complexity, novelty, allocation, repetitions, monitoring Constraints : costs, timescales, staff, equipment, building System functionality : hardware, software, network Productivity : output, quality, costs, errors, production time
  9. 9. Discuss... <ul><li>… what HCI factors should be considered while designing the Web-based courses? </li></ul>Category Factors The user: student The user: instructor User interface Organisation Constraints Productivity
  10. 10. HCI design models <ul><li>Waterfall model </li></ul><ul><li>The star life cycle model </li></ul><ul><li>Rapid prototyping </li></ul>
  11. 11. The waterfall model Requirements analysis & specification System & software design Implementation & unit testing Integration & system testing
  12. 12. The star life cycle Task analysis / functional analysis Requirements specification Conceptual design / formal design Prototyping Implementation Evaluation
  13. 13. Rapid prototyping
  14. 14. From instructional design to HCI design <ul><li>Task analysis, functional analysis </li></ul><ul><li>Conceptual design, based on selected instructional strategies and tactics </li></ul><ul><li>Physical design guidelines </li></ul>
  15. 15. Sketch… <ul><li>… a flowchart, depicting the instructional strategies and tactics you have selected for you prototype lesson. </li></ul>
  16. 16. User Interface design guidelines <ul><li>E.g. UI design guide from IBM Web site: </li></ul><ul><li>http://www.ibm.com/ibm/hci/guidelines/design/ </li></ul><ul><li>Principles: simplicity, support, familiarity, obviousness, encouragement, satisfaction, accessibility, safety, versatility, personalisation, affinity </li></ul><ul><li>Web style guidelines: specify a reason for the site, define your audience, etc. </li></ul><ul><li>Site-specific conventions: provide search & help on the left side of every page on this site </li></ul>
  17. 17. HCI resources on the Web <ul><li>IBM HCI design guide at http://www.ibm.com/ibm/hci/guidelines/design/ </li></ul><ul><li>Sun’s Web style guide: www.sun.com/styleguide </li></ul><ul><li>Designing killer Web sites www.killersites.com </li></ul><ul><li>Jakob Nielsen’s AlertBox at http://www.useit.com </li></ul><ul><li>Graphical design and visualisation, visual literacy </li></ul><ul><li>Terry Winograd, Donald Norman </li></ul>
