Field notes
The workflow assigns different responsibilities to the research team, site staff and participant, from study setup through session capture and export. Listed outputs include tremor frequency, stroke velocity and tapping rate; the page also describes quality flags and versioned metric definitions. The interactive trace is marked synthetic, so it demonstrates the interface rather than a recorded study.
