This paper introduces a new way to analyse and
visualize quantified-self or lifelog data captured from
any lifelogging device over an extended period of time.
The mechanism works on the raw, unstructured lifelog
data by detecting periodicities, those repeating patters
that occur within our lifestyles at different frequencies
including daily, weekly, seasonal, etc. Focusing on the
24 hour cycle, we calculate the strength of the 24-hour
periodicity at 24-hour intervals over an extended period
of a lifelog. Changes in this strength of the 24-hour
cycle can illustrate changes or shifts in underlying
human behavior. We have performed this analysis on
several lifelog datasets of durations from several weeks
to almost a decade, from recordings of training
distances to sleep data. In this paper we use 24 hour
accelerometer data to illustrate the technique, showing
how changes in human behavior can be identified.
