EXERCISE 4.4
A truly ubiquitous computing experience
would require the spread of computational capabilities
literally everywhere. Another way to achieve ubiquity
is to carry all of your computational need with you
everywhere, all the time. The field of wearable computing
explores this interaction paradigm. How do you think
the first-person emphasis of wearable computing compares
with the third-person, or environmental, emphasis
of ubiquitous computing? What impact would there be
on context-aware computing if all of the sensors were
attached to the individual instead of embedded in
the environment?
