  1. First experience in teaching HCI course Dusanka Boskovic Faculty of Electrical Engineering University of Sarajevo

  2. Content • Background • Organisation • Course of study • Some statistics • Conclusion 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  3. HCI Course • Background: capstone project within “ante-Bologna” course Digital Computers and Software Organization • Introduced 2009/2010 • Master studies at Automatic Control and Electronics Department, 3rd semester, elective course • D. Boskovic and Nihad Borovina • Learning outcome: • Human Computer Interface - Design and implementation • Designing HCI as approach to develop usable software 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  4. What? • Fundamental concepts of HCI • Human factor • Interaction and interface classification • User interface design methods • User cantered methods • Task oriented methods • Prototyping • Interface design patterns • Evaluation approaches • Theoretical concepts • Textbook: Jenifer Tidwel: Designing Interfaces: Patterns for Effective Interaction Design, 2005. 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  5. What? • Input: A lot of theoretical concepts • Output: Change in a way of student thinking • And a lot of practical work to be done on the way 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  6. How? • Give students something to think about • Surprise them • Expose to effects of good and bad designs • Send a clear message with assignments and lab exercises 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  7. Mental models 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  9. Assignments • Weeks 1 - 7: • HW1: Looking for an interface • HW2: GOMS method • HW3: Sensor network prototype – design patterns • Week 8: Midterm exams • Weeks 9 – 14: • Project documentation • HW4: Heuristic evaluation of a web page • Project implementation 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  10. Lab exercises • Discussing examples of a good and bad interface • Tests for measuring accessibility and visibility, human factors • Designing a prototype for a TV remote control • Space organization evaluation • Designing ATM interface prototype and discussion 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  11. Lab exercises • Designing ATM interface prototype and discussion • Smart home remote control paper prototype • Complex data visualisation • Animation techniques • Project inception, planning and implementation 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  12. Homework 1: Looking for interface • Looking for good or bad examples of user ‘interface’ • Not software, but device, map your finding to select one selected interaction principle • Problem with stating I LIKE or I DISLIKE • Message: think as a user, remember feeling happy or frustrated • 23 students AE average grade 4.3 • 20 students CI average grade 4.5 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  13. Lab: Memory test • Students were presented with screenshot of a commonly used application which they could observe for a 30 seconds and than they had to answer some questions that will show what they have noticed and remembered 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  14. Memory test 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  15. Memory test • Questions about user interface details for applications students use daily • Message: how to draw attention, how to distract user, user memory span 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  16. Lab: Space issues • Measuring areas of a web page • Tool: MS Paint • Some of UI features can be easily measured and quantified 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  17. Lab: Paper prototyping • Smart home remote control • Customers and developers teams • One customer per developer team • Customers define requirements, not detailed and too specific • Developers make paper prototype • Customer evaluates prototype with developers team • Customer and developers present the solution 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  18. Homework 2: GOMS • GOMS – goal, operator, method and selection • Working in pairs • Students defined goals and operators • One student performed task – other analysed interaction 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  19. Homework 2: GOMS • 23 students AE average grade 3.3 • 22 students CI average grade 4.3 • Messages: there are interaction analysis methods that are formal, detailed, think of time needed, applicability, results achieved,... 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  20. Homework 3: Prototype • Sensor network – design patterns 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  21. Homework 3: Prototype • Sensor network design patterns 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010

  22. Homework 4: Evaluation • Ten usability heuristics (J. Nielsen) • Visibility of system status • Match between system and the real world • User control and freedom • Consistency and standards • Error prevention • Recognition rather than recall • Flexibility and efficiency of use • Esthetical and minimalist design • Recovering from errors • Help and documentation 10th Workshop "Software Engineering Education and Reverse Engineering" Ivanjica, Serbia, 5-12 September 2010
