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

 Palm Handhelds
 Smart Phones
 model: add computation to the
device that is already networked

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

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
