1. Interaction DesignHuman-computer Interaction JMA 464/564 MWF 12:00 – 12:50 College Hall 205

2. JMA 464/545 - Instructor • Dr. Bill Gibbs • Associate Professor in Journalism & Multimedia Arts. • Ph.D. in Instructional Systems from The Pennsylvania State University. • Office 341 College Hall • Office hours – Mon., Wed. and Fri. 10:30–12:00 and 1:00-2:00 and by appointment • Phone – 412 - 396-1310 • E-mail – gibbsw@duq.edu

3. JMA 464/545 - Purpose • Course about IxD & HCI • Overview of IxD, HCI, UxD, and usability • Review IxD, HCI, UxD methods and issues

4. JMA 464/545 – Course goals • Develop understanding of IxD, human computer-interaction (HCI) and user-centered design & development. • Develop understanding of UxD, user-experience design. • Discuss development processes and tools.

5. JMA 464/545 – Course goals • Explain methods for IxD research & development. • Demonstrate general principles underlying effective interaction design and navigation control. • Use equipment and software to observe interaction.

6. JMA 464/545 – Applications & Tools • The course focuses on: • Interaction/HCI • User observation

7. JMA 464/545 – Applications & Tools • In class we use a variety of tools to prototype interactions.

8. JMA 464/545 – Applications & Tools For observations, we will use: • Observer XT • Arrington Research Eye-tracker • TechSmith – Morae • Human Factors Facility

9. Begin to observe everyday things… …how might you improve them?

10. What might happen?

11. What might happen? Pull hood latch Proximity

12. What might happen?

13. What might happen? Is the coffee maker on or off? How do you fix it?

15. Returns Web-wide results, which confuses users

16. CNN now implements search in this way.

17. Mapping. Good or Bad? A B C D

18. Is this a better design?

19. Mapping example – digital interface • You’ve been asked to develop App that controls electrical outlets in a home or building. Could organize spatially – direct relationship between outlet location and interface Could organize like this- Menu driven

20. Mapping – direct relationship between the device design and how it functions.

21. Poor designs? • Which bottle ?- Insulin Not sure what these mean? Cadillac car What do you think happens? Source: http://www.baddesigns.com/

22. People often take the path of least resistance. Try to figure out what the least resistant paths are before pouring concrete. Source: http://www.baddesigns.com/

23. People often take the path of least resistance. In a similar way, Amazon makes it easy to buy additional items.

24. Physical constraint

25. Physical constraint What happens here? Source: http://www.baddesigns.com/

26. Physical constraint – not visible What happens here? Source: http://www.baddesigns.com/

27. Logical constraint

28. Task: Return movie (DVD) to Redbox I think… similar to Conceptual model

29. Task: Return movie (DVD) to Redbox Ok, drop it in … but

30. Task: Return movie (DVD) to Redbox Must press Return A DVD first What might be a better approach?

31. Task: Return movie (DVD) to Redbox Why not a physical constraint instead of this? Return a DVD is activated when inserting DVD.

32. What might happen here? Source: http://goodexperience.com/tib/b/product_design/

33. Labels??? If the switch is pointing to "Off", it's really "On", and vice versa. Source: http://goodexperience.com/tib/b/product_design/

34. Labels??? The arrows relate to direction or how to use switch, not the final state of the switch. The words “ON/OFF” suggest the final state but they are positioned inversely to switch function. Source: http://goodexperience.com/tib/b/product_design/

35. Labels??? A simpler design is better. The switch affords/suggests how to use it. Additional labels may add confusing information.

36. How do we design for different devices? • By looking at examples in the physical world, we can become informed about how to design for: • Web • Mobile devices • Etc.

37. We’re use to this…

38. What about this…

39. What about this…

40. And the controls… What do these controls mean?

41. Design and use | Questions • How do people use different devices? • What can observing their use tell us about how we should design and develop? • How do different devices influence behavior?

42. Design and use | Questions • How do we design for the initial User Experience (UX)? • How do we design for the entire User Experience (UX)?

43. Observe human-computer interactions Example 3: Morae Example 1: Observer Example 2: Observer Example 6: CNN - EyeTrack Example 4:Post Example 5: EyeTrack Example7: Student EyeTracks Example 8: ViewPoint Analysis
