Video is a powerful tool in ergonomic observations. However it is often time consuming to record a video and to identify demanding work postures. A time-saving method was developed: information from direct measurements synchronized with video of a body worn video camera was utilized to identify reasons for demanding work moments. This method was successfully tested on a 5.5-hour work shift of a garbage collector: 17 of 18 events when the worker bended forward were quickly identified in a video editing software with guidance of inclination data (inserted as an audio track) from an accelerometer attached to the worker’s back.
