Description
Industrial operators from a television plant in Istanbul, Turkey were recorded as they carried out their professional tasks on a production line for assembling televisions. Four healthy people, three men and one woman, participated in the MoCap recording session. Their average age was 31.5±6.2 years, their height was 167.8±4.6 cm, and their average weight of 65.3±9.9 kg.
