The major task facing an evaluator is that of presenting the reference signals
to the device under test, and collecting annotation files from the device. The
details of this task will vary for each device, but a few general hints are
given below. A second task, that of obtaining reference heart rate
measurements, should be a much simpler job. Once all of this information has
been gathered, the remaining work required -- that of comparing the device's
analysis against the ``gold standard'' -- can be performed automatically.
