Technical observations
In addition to the qualitative information
captured through the pretrial and post-trial
interviews, the PMD can record quantitative
measures to gain further insight into assessing
the usefulness of the technology. Such measures
could include GSM signal strength, PMD
power consumption, accelerometer data (if
supported by mobile device), server communication
stability, time taken for user acknowledgement
of reminder, and indication of
which region of the acknowledgment button
was pressed. To date, only data about the communication
stability between the PMD and
server has been integrated into the system.
