2 The origins of ubiquitous computing research at PARC in the late 1980s  urnal/sj/384/weiser.html

3 The Coming Age of Calm Technology

4 Some Computer Science Issues in Ubiquitous Computing

5 Ubiquitous Computing  networked  …but to make the world “calmer”, not to connect your faucet to your cell phone

6 “for every ant in the world today there are 100 transistors” - Gordon Moore, 2003

7 Computing by the inch, foot, & yard  At each scale, the devices have input, computation, and output  Different than more recent work (e.g., that of Abowd et al) where these elements are often decoupled

9 Rem Koolhaas: S M L XL

10 Computing by the inch, foot, & yard  Originally: ParcTabs  Today  Palm Handhelds  Smart Phones  model: add computation to the device that is already networked

11 Computing by the inch, foot, & yard  ParcPads  Today: Tablet Computers

12 Computing by the inch, foot, & yard  LiveBoards  Today: SMART Boards

13 Privacy  Dog food / kool aid  Danyel Fisher and  The nurses in east bay express

14 Evaluation  With embodied virtuality, “tasks” aren’t as discrete, and evaluation (both methods and metrics) is much harder

15 Foreground & Background Interaction  Buxton 1980s  Hinckley TOCHI

16 Mobile: What actually happened

17 Making Sense of Sensing Systems  Bellotti et al., CHI 2002  When I address a system, how does it know I am addressing it?  When I ask a system to do something how do I know it is attending?  When I issue a command (such as save, execute or delete), how does the system know what it relates to?  How do I know the system understands my command and is correctly executing my intended action?  How do I recover from mistakes?

18 At Home with Ubiquitous Computing  Edwards & Grinter, Ubicomp 2001  The "Accidentally" Smart Home  Impromptu Interoperability  No Systems Administrator  Designing for Domestic Use  Social Implications of Aware Home Technologies  Reliability

19 Unpacking Privacy  Dourish and Palen, CHI
