Daily human behavior is often quantified as being activities that are characterized by certain duration, a certain degree of recurrence, a certain temporal location, and a certain relation to other activities. Additionally, they take place at a certain location, in presence of absence of others, and are motivated by different reasons. These so-called parameters of time (e.g. duration, tempo, timing, and sequence) and their contextual information are captured in a most reliable manner through time-diary methodology.
The research group TOR has developed expertise on collecting time-use data and their analysis.
