Key personalized reminders were assessed
using a mixture of simulated and real scenarios.
Simulated scenarios involved, for example,
placing a phone call to the research nurse, while
real scenarios were guided by the participants’
needs and included, for example, reminders to
have lunch or to begin preparations for an
appointment. The functionality of the PMD
was measured by considering successful interaction
with the device, video transmission rate,
video and audio quality, and reliability of
reminder delivery through patient acknowledgement
via button interaction with the device.
