If position were measured instead of range this could be used to document activities-of-daily-living, for the elderly or to measure health information for anyone (humans or pets). Precision location could be used to detect cooking, fridge visits, bathroom visits, exercise, time in bed, possibly time sleeping, overall activity (or lack thereof, possibly indicating a health decline if extended over a long time), and more. There has been research on trying to do this with accelerometers and RFID tags, possibly recent research has tried UWB tags.
