their health, wellness, and other life
experiences. The Omni Track project
is our ongoing effort to fill the gap in
promoting personalized tracking.
We have been extending Omni Track
as a toolkit for other researchers to
employ personalization, and we have
examined ways to elicit personalized
tracking needs for different health
contexts. As for the next step, the
following questions remain: How might
a personalized tracking approach
affect clinical workflow? How can we
support the seamless sharing of patient-generated data in the clinical setting?
Would the sharing of the data collected
from personalized tracking lead to
patient engagement and meaningful
health outcomes? Further research is
needed to examine whether and how the
personalized tracking approach can lead
to tangible outcomes.
