5. Information Processing Model of Cognition

6. What does this imply? Personal computing: empowering the individual --> interface designed and optimized for the individual. But we live and work with other people. Our computers are connected to other computers.

11. Where do you look for traffic signals?  In the US?  In France?

12. Where do you look for traffic signals?  In the US?  In France? ANSWER: Off to the right at eye level

13. What are some other concepts that are driven by social convention?

14.  Language  Politeness  Privacy  Gestures  Money

19. CSCW, CSCW or CSW?  Computer Supported Collaborative Work  North American  Computer Supported Cooperative Work  European (and ACM)  Often uses “participatory design” method  Computer Supported Work  Aka “Knowledge work”  “Do you want fries with that?”

20. A few terms:  Synchronous IM, chat  Asynchronous e-mail  Remote  Colocated “in the same physical space”  Flow “really getting into it”  Work flow “the passing of artifacts from one person to another for different processing”  Participatory design getting users to actively design with designers  Seamlessness integrating control into activity of application  Deictic reference resolving “this” and “that” e.g. pointing

21. From 1 to many  One Brain, One Computer  The Social Realm  Beyond the information processing model  CSCW, CSCW or CSW?  Computers Everywhere  Ubiquitous computing  Augmented reality

22. Ubiquitous Computing aka “Pervasive Computing”  Mark Weiser / PARC (also Roy Want, Rich Gold, me, others)  Instead of 1 computer / person, 100’s / person  HCI consequence:  100’s of interfaces / person  Each one does single task  Each can be simple interface  Embedded in environment

23. Ubiquitous Computing

24. From Ubiquitous Computing to “Pervasive Computing”  Analogs of writing surfaces:  Whiteboard/wallsize --> “Liveboard/Smartboard”  Notepad size --> laptops and notepad  Scrap paper --> PDA’s

25. From Ubiquitous Computing to “Pervasive Computing”  Video: iLand (Dr. Dr. N. Strietz)

26. From Ubiquitous Computing to “Pervasive Computing” McCullough’s Three Milestones of Interaction Design: 1. People and Machines (1920-1960) designers reduce “friction”, make safer, sell more products 2. Personal Computing or HCI (1960-2000) designers help people participate in computing, make useable, and create tools that match cognition 3. Interaction Design (2000- ????) Information technology is the ambient social infrastructure; designers create context a well as content.
