…but to make the world

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

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

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

Computing by the inch,

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

Privacy
 Dog food / kool aid
 Danyel Fisher and email
 The nurses in east bay express
13
Evaluation
 With embodied virtuality,
“tasks” aren’t as discrete,
and evaluation (both methods
and metrics) is much harder

Foreground & Background
Interaction
 Buxton 1980s
 Hinckley TOCHI

Mobile: What actually
happened

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?

 The "Accidentally" Smart Home
 Impromptu Interoperability
 No Systems Administrator
 Designing for Domestic Use
 Social Implications of Aware
Home Technologies
 Reliability
