Talk Abstract:
Mobile phones promise to replace

the desktop as the predominant
computing-and-communications platform.

Yet simply reproducing
desktop application genres -- e-mail web brows

ing and
streaming video to name a few -- in a small form-factor
c

annot achieve this promise. A new vision for mobile computing
is requi

red. A critical yet under-explored element of this
vision is the use o

f personal context.

For example early studies showed that context-a

wareness
can improve the usefulness of automated reminders but little

is known about how a context-aware reminder application
might be us

ed throughout a person''s daily life. Mobile
phones provide a potentia

lly convenient and truly ubiquitous
platform for the detection of perso

nal context such as location
as well as the delivery of reminders. To
study people using
location-aware reminders throughout their daily liv

es we
designed Place-Its a location-based reminder application
th

at runs on mobile phones. This talk describes the design
of Place-Its

and a two week exploratory user study. The
study reveals that location

-based reminders are useful
in large part because people use location

in nuanced ways.

Other on-going projects relating to mobile phones a

re briefly discussed.
